BACKGROUND OF THE INVENTION

Paclobutrazol was first disclosed in US 4243405. Paclobutrazol is chemically known as (aR,bR)-rel-b-[(4-Chlorophenyl)methyl]-a-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol and having chemical structure as below;

Paclobutrazol (PBZ) is a plant growth retardant and triazole fungicide. It is a known antagonist of the plant hormone gibberellin. It acts by inhibiting gibberellin biosynthesis, reducing internodial growth to give stouter stems, increasing root growth, causing early fruitset and increasing seedset in plants such as tomato and pepper. PBZ has also been shown to reduce frost sensitivity in plants. Moreover, paclobutrazol can be used as a chemical approach for reducing the risk of lodging in cereal crops.(kamran et al 2017). PBZ is used by arborists to reduce shoot growth and has been shown to have additional positive effects on trees and shrubs. Among those are improved resistance to drought stress, darker green leaves, higher resistance against fungi and bacteria, and enhanced development of roots. Cambial growth, as well as shoot growth, has been shown to be reduced in some tree species.

Mancozeb is a dithiocarbamate non-systemic agricultural fungicide with multi-site, protective action on contact. It is a combination of two other dithiocarbamates: maneb and zineb. The mixture controls many fungal diseases in a wide range of field crops, fruits, nuts, vegetables, and ornamentals. It is marketed as Penncozeb, Trimanoc, Vondozeb, Dithane, Manzeb, Nemispot, and Manzane.

Propineb is a dithiocarbamate fungicide. It has been evaluated several times by the JMPR, the initial evaluation being in 1977 and the latest residues evaluation being in 1993 for residues and toxicology. Contact fungicide based used as a foliar spray for the control of fungal diseases in different crops Apple, Potato, Chilli, Tomato, Grapes, Grapes and Pomegranate.

Folpet is a protective leaf-fungicide. Its mode of action inhibits normal cell division of a broad spectrum of microorganisms. It is used to control cherry leaf spot, rose mildew, rose black spot, and apple scab. Used on berries, flowers, ornamentals, fruits and vegetables, and for seed- and plant- bed treatment. Also used as a fungicide in paints and plastics, and for treatment of internal and external structural surfaces of buildings. Incompatible with strongly alkaline preparations, such as lime sulfur,

Captan is man-made fungicide used to control a range of fungal diseases. The pesticide was first registered in 1951. Captan can be used to control plant diseases such as black rot, early and late blight, and downy mildew, among others. Captan works by coming into contact with a fungus and interrupting a key process in its life cycle. It can be toxic to many different fungal diseases. Captan is non-systemic, which means it is not expected to move through plants.

Captafol is a fungicide. It is used to control almost all fungal diseases of plants except powdery mildews. It is believed to be a human carcinogen, and production for use as a fungicide in the United States stopped in 1987. Its continued use from existing stocks was allowed, but in 1999 the Environmental Protection Agency banned its use on all crops except onions, potatoes, and tomatoes. In 2006 even these exceptions were disallowed, so currently its use on all crops is banned in the United States,

Dithianon is a synthetic compound of the quinine family. It acts as a conventional, protective, broad spectrum fungicide in apples, pears and many other fruits. Dithianon is applied as a foliar spray, and is surface acting. Dithianon adheres well to the surface of the leaves, and once dried gives good persistence and is relatively rainfast. It is also possible for the compound to be reactivated on the surface of the plant by rain and run off, resulting in a certain level of protection to new growth. The mode of action of dithianon is that it is a multi-site inhibitor of protein formation that acts by modifying the sulfydryl groups found in the cysteine residues of many proteins. This protein inhibition prevents spore germination and germ tube growth.

Metalaxyl-M is a methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)alaninate that is the more active R-enantiomer of metalaxyl. A systemic fungicide, it is active against phytopathogens of the order Peronosporales and is used to conrtrol Pythium in a number of vegetable crops. It has a role as an agrochemical. It is a methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)alaninate, a D-alanine derivative, an acylamino acid fungicide and an anilide fungicide. It derives from a D-alanine. It is an enantiomer of a (S)-metalaxyl.

Azoxystrobin (brand name Amistar, Syngenta) is a systemic fungicide commonly used in agriculture. The substance is used as an active agent protecting plants and fruit/vegetables from fungal diseases. Azoxystrobin possesses the broadest spectrum of activity of all known antifungals. It is the only counteragent that has the ability to protect against the four big groups of fungal and fungal-like diseases.

Picoxystrobin is the new strobilurin fungicide developed specifically by Syngenta to control cereal diseases in early season. It differs from the existing strobilurins thanks to its complete biokinetic properties, such as a rapid uptake, systemic and translaminar movements vapour phase activity, strong affinity with the wax layer, a protection of newly formed organs and also a curative activity. Picoxystrobin will deliver better disease control and yield within a cereal fungicide programme. It is developed as a straight product or in a ready-to-use mixture with hexaconazole, a well-known fungicide from the triazole group, and will be recommended in early season applications.

Isoprothiolane is a malonate ester that is diisopropyl malonate in which the two methylene hydrogens at position 2 are replaced by a 1,3-dithiolan-2-ylidene group. An insecticide and fungicide used to control a range of diseases including Pyricularia oryzae, Helminthosporium sigmoideum and Fusarium nivale. It has a role as an insecticide, an environmental contaminant, a phospholipid biosynthesis inhibitor and an antifungal agrochemical. It is a malonate ester, a member of dithiolanes and an isopropyl ester. It derives from a malonic acid.

Tricyclazole (5-methyl-1,2,4-triazolo[3,4-b]benzothiazole) is a unique fungicide for control of Pyricularia oryzae on rice. Tricyclazole is systemic in rice and will control rice blast disease in any stage of plant development by a variety of application methods. Tricyclazole protects plants from infection by P. oryzae by preventing penetration of the epidermis by the fungus. The compound acts by inhibiting melanization within the appressorium, thus causing a lack of rigidity in the appressorial wall. Tricyclazole has no apparent effect on spore germination although sporulation is reduced. Tricyclazole is not curative but is protective in its activity.

Hexaconazole is a Broad-spectrum systemic triazole fungicide used for the control of many fungi particularly Ascomycetes and Basidiomycetes. Major consumption is in Asian countries and it is used mainly for the control of rice sheath blight in China, India, Vietnam and parts of East Asia. It is also used for control of diseases in various fruits & vegetables.

Validamycin is a non-systemic antibiotic with fungicide action. It is produced from fermentation of streptomyces hygroscopicus variety limoneus. It is most effective against soil borne diseases and is used for the control of Rhizoctonia solani in rice, potatoes, vegetables, and others as well as damping off diseases in vegetable seedlings, cotton, sugar beets, rice and other plants. The U.S. EPA has classified validamycin as Toxicity Class IV- practically non-toxic.

The main concern with the use of fungicide is the development of resistance by the pests for that particular fungicide and at the end one has to apply more concentrated formulation of the fungicide. The high amount of fungicide may results in the toxicity to human beings as well as has bad effect on environment.

Previously people have tried many alternatives and option to overcome this problem and as a result developed poly mixture of pesticide, use of non-toxic ingredients and developing novel formulations which provides effective amount of the fungicide and at the required part only.

However the use of poly mixture containing large number of fungicide poses a problem in many was like preparing formulation of multiple fungicide with different chemical properties and behavior and physical properties. It also creates challenge for formulator in term of compatibility and stability of all the fungicide along with used excipients in the formulation.

DETAILED DESCRIPTION OF THE INVENTION

The term "health of a plant" or "plant health" is defined as a condition of the plant and/or its products. As a result of the improved health, yield, plant vigor, quality and tolerance to abiotic or biotic stress are increased. Noteworthy, the health of a plant when applying the method according to the invention, is increased independently of the pesticidal properties of the active ingredients used because the increase in health is not based upon the reduced pest pressure but instead on complex physiological and metabolic reactions which result for example in an activation of the plant's own natural defense system. As a result, the health of a plant is increased even in the absence of pest pressure.

Accordingly, in an especially preferred embodiment of the method according to the invention, the health of a plant is increased both in the presence and absence of biotic or abiotic stress factors.

The above identified indicators for the health condition of a plant may be interdependent or they may result from each other. An increase in plant vigor may for example result in an increased yield and/or tolerance to abiotic or biotic stress. One indicator for the condition of the plant is the yield. "Yield" is to be understood as any plant product of economic value that is produced by the plant such as grains, fruits in the proper sense, vegetables, nuts, grains, seeds, wood (e.g. in the case of silviculture plants) or even flowers (e.g. in the case of gardening plants, ornamentals). The plant products may in addition be further utilized and/or processed after harvesting.

In an especially preferred embodiment of the invention, the yield of the treated plant is increased.

In another preferred embodiment of the invention, the yield of the plants treated according to the method of the invention, is increased synergistically.

According to the present invention, "increased yield" of a plant, in particular of an agricultural, silvicultural and/or horticultural plant means that the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the mixture according to the invention.

A further indicator for the condition of the plant is the plant vigor. The plant vigor becomes manifest in several aspects such as the general visual appearance.
In another especially preferred embodiment of the invention, the plant vigor of the treated plant is increased. In another preferred embodiment of the invention, the plant vigor of the plants treated according to the method of the invention is increased synergistically.

The improvement of the plant vigor according to the present invention particularly means that the improvement of any one or several or all of the above mentioned plant characteristics are improved independently of the pesticidal action of the mixture or active ingredients (components).Another indicator for the condition of the plant is the "quality" of a plant and/or its products.

In an especially preferred embodiment of the invention, the quality of the treated plant is increased.

In another preferred embodiment of the invention, the quality of the plants treated according to the method of the invention, is increased synergistically.

According to the present invention, enhanced quality means that certain plant characteristics such as the content or composition of certain ingredients are increased or improved by a measurable or noticeable amount over the same factor of the plant produced under the same conditions, but without the application of the mixtures of the present invention. Enhanced quality can be characterized, among others, by following improved properties of the plant or its product:
• Increased nutrient content
• Increased protein content
• Increased content of fatty acids
• Increased metabolite content
• Increased carotenoid content
• Increased sugar content
• Increased amount of essential amino acids
• improved nutrient composition
• improved protein composition
• improved composition of fatty acids
• improved metabolite composition
• improved carotenoid composition
• improved sugar composition
• improved amino acids composition
• Improved or optimal fruit color • improved leaf color
• Higher storage capacity
• Higher process ability of the harvested products.

Another indicator for the condition of the plant is the plant's tolerance or resistance to biotic and/or abiotic stress factors. Biotic and abiotic stress, especially over longer terms, can have harmful effects on plants. Biotic stress is caused by living organisms while abiotic stress is caused for example by environmental extremes. According to the present invention, "enhanced tolerance or resistance to biotic and/or abiotic stress factors" means that certain negative factors caused by biotic and/or abiotic stress are diminished in a measurable or noticeable amount as compared to plants exposed to the same conditions, but without being treated with a mixture according to the invention and that the negative effects are not diminished by a direct action of the mixture according to the invention on the stress factors, e.g. by its fungicidal or insecticidal action which directly destroys the microorganisms or pests, but rather by a stimulation of the plants' own defensive reactions against said stress factors.

The novel pesticidal composition of present invention comprising Paclobutrazol, at least one more active ingredient selected from Mancozeb, Propineb, Folpet, Captan, Captafol, Dithianon, Sulphur, Metalaxyl M, Azoxystrobin, Picoxystrobin, Isoprothiolane, Tricyclazole, Hexaconazole and Validamycin may further comprises inactive excipients including but not limited to dispersant, anti-freezing agent, anti-foam agent, wetting agent, suspension aid, anti-microbial agent, thickener, quick coating agent or sticking agents (also referred to as “stickers” or “binders”) and buffering agent.

Surfactants that are used as dispersants have the ability to adsorb strongly onto a particle surface and provide a charged or steric barrier to re-aggregation of particles. The most commonly used surfactants are anionic, non-ionic, or mixtures of the two types. For wettable powder formulations, the most common dispersants are sodium lignosulphonates. For suspension concentrates, very good adsorption and stabilization are obtained using polyelectrolytes, such as sodium naphthalene sulphonate formaldehyde condensates. Tristyrylphenolethoxylate phosphate esters are also used. Nonionics such as alkylarylethylene oxide condensates and EO-PO block copolymers are sometimes combined with anionics as dispersants for suspension concentrates. In recent years, new types of very high molecular weight polymeric surfactants have been developed as dispersants. These have very long hydrophobic ‘backbones’ and a large number of ethylene oxide chains forming the ‘teeth’ of a ‘comb’ surfactant. These high molecular weight polymers can give very good long-term stability to suspension concentrates because the hydrophobic backbones have many anchoring points onto the particle surfaces. Examples of dispersants used herein include but not limited to sodium lignosulphonates; sodium naphthalene sulphonate formaldehyde condensates; tristyrylphenolethoxylate phosphate esters; aliphatic alcohol ethoxylates; alky ethoxylates; EO-PO block copolymers; and graft copolymers or mixtures thereof.

Anti-freezing agent as used herein can be selected from the group consisting of polyethylene glycols, methoxypolyethylene glycols, polypropylene glycols, polybutylene glycols, glycerin and ethylene glycol.

Water-based formulations often cause foam during mixing operations in production. In order to reduce the tendency to foam, anti-foam agents are often added either during the production stage or before filling into bottles. Generally, there are two types of anti-foam agents, namely silicones and non-silicones. Silicones are usually aqueous emulsions of dimethyl polysiloxane while the non-silicone anti-foam agents are water-insoluble oils, such as octanol and nonanol, or silica. In both cases, the function of the anti-foam agent is to displace the surfactant from the air-water interface.

Examples of wetting agents used in wettable powder, suspension concentrate, and water-dispersible granule formulations include but not limited to sodium lauryl sulphate; sodium dioctylsulphosuccinate; alkyl phenol ethoxylates; and aliphatic alcohol ethoxylates or mixtures thereof.

Suspension aid in the present description denotes a natural or synthetic, organic or inorganic material with which the active substance is combined in order to facilitate its application to the plant, to the seeds or to the soil. This carrier is hence generally inert, and it must be agriculturally acceptable, in particular to the plant being treated. The carrier may be solid (clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers, and the like or mixtures thereof) or liquid (water, alcohols, ketones, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons, liquefied gases, and the like or mixtures thereof).

Biocides / Microorganisms cause spoilage of formulated products. Therefore anti-microbial agents are used to eliminate or reduce their effect. Examples of such agents include, but are not limited to: propionic acid and its sodium salt; sorbic acid and its sodium or potassium salts; benzoic acid and its sodium salt; p-hydroxy benzoic acid sodium salt; methyl p-hydroxy benzoate; and biocide such as sodium benzoate, 1,2-benzisothiazoline-3-one, 2-methyl-4-isothiazolin-3-one, 5-chloro-2-methyl-4-isothiazolin-3-one, potassium sorbate, parahydroxy benzoates or mixtures thereof.

Thickening, gelling, and anti-settling agents generally fall into two categories, namely water-insoluble particulates and water-soluble polymers. It is possible to produce suspension concentrate formulations using clays and silicas. Examples of these types of materials, include, but are limited to, montmorillonite, e.g. bentonite; magnesium aluminum silicate; and attapulgite. Water-soluble polysaccharides have been used as thickening-gelling agents for many years. The types of polysaccharides most commonly used are natural extracts of seeds and seaweeds are synthetic derivatives of cellulose or mixtures thereof. Examples of these types of materials include, but are not limited to, guar gum; locust bean gum; carrageenam; xanthan gum; alginates; methyl cellulose; sodium carboxymethyl cellulose (SCMC); hydroxyethyl cellulose (HEC) or mixtures thereof. Other types of anti-settling agents are based on modified starches, polyacrylates, polyvinyl alcohol and polyethylene oxide or mixtures.

The quick coating agent can be a conventionally available sticker, for example polyesters, polyamides, poly- carbonates, polyurea and polyurethanes, acrylate polymers and copolymers, styrene copolymers, butadiene copolymers, polysaccharides such as starch and cellulose derivatives, vinylalcohol, vinylacetate and vinylpyrrolidone polymers and copolymers, polyethers, epoxy, phenolic and melamine resins, polyolefins and define copolymersand mixtures thereof. Examples of preferred polymers are acrylate polymers such as poly(methacrylate), poly(ethyl methacrylate), poly(methylmethacrylate), acrylate copoylmers and styrene-acrylic copolymers as defined herein below, poly(styrene-co maleic anhydride), cellulosic polymers such as ethyl cellulose, cellulose acetate, cellulose acetatebutyrate, acetylated mono, di, and triglycerides, poly(vinylpyrrolidone), vinyl acetate polymers and copolymers, poly(alkylene glycol), styrene butadiene copolymers, poly(orthoesters), alkyd resins, and mixtures of two or more of these. Polymers that are biodegradable are also useful in the present invention. As used herein, a polymer is biodegradable if is not water soluble, but is degraded over a period of several weeks when placed in an application environment. Examples of biodegradable polymers that are useful in the present invention include biodegradable polyesters, starch, polylactic acid starch blends, polylactic acid, poly(lactic acid-glycolic acid) copolymers, polydioxanone, cellulose esters, ethyl cellulose, cellulose acetate butyrate, starch esters, starch esteraliphatic polyester blends, modified corn starch, polycaprolactone, poly(namylmethacrylate), wood rosin, polyanhydrides, polyvinylalcohol, polyhydroxybutyratevalerate, biodegradable aliphatic polyesters, and polyhydroxybutyrate or mixtures thereof.

Buffering agent as used herein is selected from group consisting of calcium hydroxyapatite, PotassiumDihydrogen Phosphate, Sodium Hydroxide, carbonated apatite, calcium carbonate, sodium bicarbonate, tri-calcium phosphate, calcium phosphates, carbonated calcium phosphates, amine monomers, lactate dehydrogenase and magnesium hydroxide.

The solvent for the formulations of the present invention may include water, water-soluble alcohols and dihydroxy alcohol ethers. The water-soluble alcohol which can be used in the present invention may be lower alcohols or water-soluble macromolecular alcohols. The term "lower alcohol", as used herein, represents an alcohol having 1-4 carbon atoms, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, etc. Macromolecular alcohol is not limited, as long as it may be dissolved in water in a suitable amount range, e.g., polyethylene glycol, sorbitol, glucitol, etc. The examples of suitable dihydroxyalcohol ethers used in the present invention may be dihydroxy alcohol alkyl ethers or dihydroxy alcohol aryl ethers. The examples of dihydroxy alcohol alkyl ether include ethylene glycol methyl ether, diethylene glycol methyl ether, propylene glycol methyl ether, dipropylene glycol methyl ether, ethylene glycol ethyl ether, diethylene glycol ethyl ether, propylene glycol ethyl ether, dipropylene glycol ethyl ether, etc. The examples of dihydroxy alcohol aryl ethers include ethylene glycol phenyl ether, diethylene glycol phenyl ether, propylene glycol phenyl ether, dipropylene glycol phenyl ether, and the like. Any of the above mentioned solvent can be used either alone or in combination thereof.

Biological Examples:
The synergistic pesticide action of the inventive mixtures can be demonstrated by the experiments below. A synergistic effect exists wherever the action of a combination (ready-mix) or tank mix of active ingredient is greater than the sum of the action of each of the components alone. Therefore a synergistically effective amount or an effective amount of a synergistic composition or combination is an amount that exhibits greater pesticide activity than the sum of the pesticide activities of the individual components. In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S.R. in an article entitled “ Calculation of the synergistic and antagonistic responses of herbicide combinations” published in the journal Weeds, 1967, 15, p.20-22, incorporated herein by reference in its entirety. The action expected for a given combination of two active components can be calculated as follows:
Colby’s Formula:

To study the synergistic effect of Paclobutrazol and fungicide, field trial was conducted in groundnut (Arachis hypogaea).
Example 1
The objective of the present study was to study the synergism between paclobutrazol and fungicide.
Details of Experiment:
a) Experiment design : Randomized Block Design
b) Replication : Three
c) Treatments : Twelve
d) Plot size : 20 sq.m.
e) Spacing : 75 cm x 15 cm
f) Test Crop & Variety : Groundnut, J 11
g) Time of application : 45 DAS (Days after sowing)
h) Spray method : Manually operated knap sack sprayer, using 500
liter per hectare Water volume

Evaluation Method : The observation was recorded at 60 and 75 days after sowing. Disease severity (Tikka Leaf spot disease caused by Cercospora arachidicola) was recorded from 100 leaflet per plot and disease severity was calculated and % disease reduction calculated. The pod count i.e. number of pods per plat was recorded at the time of harvest.
