Description:FIELD OF THE INVENTION
The present disclosure relates to a controlled release semi-solid water dispersible emulsion formulation comprising semiochemical/s, in particular, relates to a formulation of semiochemical/s in the form of cream or gel or paste with variable viscosity. The formulation is amenable to manual or mechanical applications in agriculture and which is compatible with or without insecticides. Further, the present disclosure relates to a semiochemical/s delivery vehicle / diffuser, in a natural environment to trigger insect chemical behavioural modification for season long insect control.
BACKGROUND OF THE INVENTION
The global population is projected to increase around 9.7 billion by 2050, which will result in a tremendous demand for food. With the increase in the global population, there will be a corresponding increase in the demand for food to feed the growing population. Various strategies are being used to increase the supply of food including better irrigation for soil based agriculture, aeroponics, hydroponics, and pest management by use of chemicals (such as insecticides, pesticides), genetic modification of plants / organisms, integrated pest management.
Insecticides have a wide application in the field of agriculture and industry. They are being used for a number of years to increase the crop yield by controlling insects that harm crops/ food. However, there are many drawbacks associated with the use of insecticides, such as harmful to non-target organisms, to beneficial insects, building up of resistance by the insects, and environment. They have the potential to alter biodiversity and ecosystem components majorly and are toxic to animals as well as humans. Some insecticides become concentrated as they spread in the food chain. Traditional pest control methods relies on indiscriminate use of insecticides being sprayed at regular intervals from sowing to harvest has induced insecticide resistance.
With the growing insecticide resistance, failing genetic modification of plants / organisms and scant environmentally friendly new chemical pest control molecules in pipeline, there is a need to develop pest control technologies by way of new mechanism of action by use of nontoxic chemicals.
Insect Pheromones which are species specific have proven useful in pest control and have become essential components of crop protection as part of Integrated Pest management. The eco-friendly semiochemical based pest control strategies developed are by way of using sex pheromones for mating disruption & mass trapping, host-plant volatiles are used for attract & Kill, Push Pull techniques that have largely replacing conventional insecticides. Though very effective these semiochemical compounds are used in very high amounts and so far formulated in polymer based protective matrices. Another drawback is that they have been inefficiently deployed in field in the form of plastic dispensers (Ex: hand-applied ropes, tapes, and sachets) all of which have limited the adoption of the technology.
Semiochemical/s (AI) intended to create semiochemical plumes or cloud or atmospheric saturation of the crop field to modify insect behaviour to control the target pest require very low amounts of pheromone . However, due to inefficient diffusers a very high doses of expensive semiochemicals per treated area currently ranging from 80 grams to 250 grams per hectare, have inconsistent performances, generate plastic waste and are very expensive limiting the adoption of use of the technology. The dose presently in use and registered globally for the purpose of mating disruption use exorbitantly very high dose of pheromone than actually required. Based on existing reports on the amount of pheromone females release in environment it’s obvious that we can disrupt mating with even 1/10thth of the A.I quantity presently registered and commercially in use. Thus for the technology to be adopted a diffuser which can release semiochemicals close to zero or 1st order and the one which is not effected by environmental variations like rain, wind, UV rays and temperature and last season long in the field will help adopt the technology replacing conventional insecticides.
Various compositions related to agrochemicals for controlling insects and methods for preparing the same are known in the art and are elucidated hereinafter. Method for the preparation of micro capsular formulations of agrochemicals comprises preparing the paste or suspension of the conventional active agrochemical ingredient in vegetable oil and dispersing the resultant paste/solution in water. Compositions to attract and kill insect pests comprising an organic biodegradable matrix component from natural sources; an organic biodegradable ultraviolet light absorbent matrix component from natural sources; a biodegradable insecticidal or acaricidal compound; and a pheromonal or kairomonal attractant and procedures to prepare it are known.
Stabilized insect mating disruption pheromone composition comprising an insect pheromone and 2,2′-Methylenebis(6-t-butyl-p-cresol) and methods of use and microcapsules containing these compositions are also known.
Fre´De´Rique M. De Lame et.al [Development and Evaluation of an Emulsified Paraffin Wax Dispenser for Season-Long Mating Disruption of Grapholita molesta in Commercial Peach Orchards. J. Econ. Entomol. 100(4): 1316Ð1327 (2007)] describes a sprayable composition with paraffin wax after emulsification with water in combination of pheromones for mating disruption of Grapholita molesta in peach orchard. The major drawback of this composition is that, the method of preparation is not disclosed, dollops were applied with the spatula or as sprayable and only focused towards application side in the agricultural field.

[Development of natural waxes dispensers for pheromones and use in mating disruption of the ambrosia beetle Megaplatypus mutatus in poplar (Populus spp) plantations; Agroforestry Systems · May 2016], Monolithic solid dispensers for mating disruption of ambrosia beetle using Lanolin wax and bee wax in combination with pheromones. The system was thoroughly mixed in molten state and poured into a mold with half sphere shaped. The major drawback of this product is that, it is solid in nature and require some hanging or tying support on the plant or in agricultural field. The release rates exhibits shorter release of not more than six weeks.
US6001346 discloses a sprayable or solid formulation which uses biodegradable wax carrier for insect pheromones and a method for constant release rate of the pheromone from the biodegradable wax. A composition comprising a pheromone and paraffin wax formulated as an aqueous emulsion or in a solid form. suitable for application to a surface of a tree or crop for mating disruption of insect pests. Pheromone is released by diffusion or by partitioning from the biodegradable wax carrier or by pheromone exposure due to the biodegradable wax carrier degradation. The major drawback of this patent is that, method of preparation of formulation and composition is not clearly disclosed, type or nature of aqueous emulsion or a solid is not described, release duration is very short up to three weeks and only focused towards application side in agricultural field. Additionally, other disadvantages of this formulation is that, it is not water dispersible, uses very low concentration of surfactant which leads to physicochemical instability. The formulation does not describe the use of any adhesion promoter so majority of applied dollop may fall down from the plant surface.
Thus, there exists an unmet need for a semiochemical controlled release formulation for insect behaviour modification either by confusion or disorientation and mating disruption, or an attraction and kill to achieve insect control and prevent crop damage. These formulations will be an effective integrated pest management tool and will serve as a replacement to use of harmful broad-spectrum insecticides. We need cost effective, water dispersable and efficient semiochemical/s diffuser which lasts for season long in agriculture field conditions. which also exhibits physicochemical stability under long term storage conditions and rainfastness in field after application on crop. OBJECTIVES OF THE INVENTION
Objective of the present invention is to provide a water dispersible controlled release semi solid formulation containing semiochemical/s resistant to environmental temperature, humidity, and rainy condition, for control of insect pests which are harmful to agrarian crops by means of attract and kill technique, confusion and disorientation or mating disruption (MD) or male annihilation technique (MAT).
Another objective of the present disclosure is to provide a semisolid composition which adheres to wet / dry plant surface or any solid substrate.
Another objective of the present disclosure is to use natural mesoporous materials to regulate release of semiochemical/s as a controlled release material.
Another objective of the present disclosure is to use high surface area carbon for adsorption of semiochemical/s for controlled release.
Another objective of the present disclosure is to use minimum amount of semiochemical/s to achieve season long insect behaviour modification lasting at least a minimum of 2 months and up to 5 months.
Still another objective of the present disclosure is to provide a composition which is amenable to various forms of application systems, to deliver required amount of formualtion in the field.
Yet another objective of the present disclosure is to provide a process for the preparation of controlled release semi solid composition.
Still another objective of the present disclosure is to provide water dispersible property to aid addition of insecticide, which can be used for attract and kill strategy with compatible chemical insecticides.
Another objective of the present disclosure is to provide an eco-friendly, stable, non-phytotoxic, cost-effective, biodegradable and insect specific semiochemical/s controlled release system, which is alternative to existing chemical / bio pesticide systems. The formulation can be prepared with variable viscosity to suit various crops, geographies and equipment used for application. The formulation can be packed and stored in a laminated tubes and applied on the plant foliage or tree surface or any other surface in agricultural field.
Other objectives and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.

This contributed to an average yield increase of 58% in Maharashtra, 44% in Karnataka and 41.4 % in Gujarat over control. The percentage green boll damage was lesser in the controlled release paste (PBW) treated plots when compared to the farmer’s practices adopted control plot. The percentage green boll damage was in the range of 5.14% to 17.1% and 14.0 to 24.29% in the treated and control plots, respectively.
The semi-solid formulation of the present disclosure controlled release paste along with BFSB semiochemical/s was applied in the form of dollops in different fields of brinjal in Karnataka and Maharashtra for disrupting the mating of Brinjal fruit and shoot borer, Leucinodes orbonalis by and 90.6% respectively. This contributed to an average yield increase of 8.5%. The percentage fruit damage was lesser in the controlled release paste (BFSB) treated plot when compared to the farmer’s practices adopted control plot. The percentage fruit damage was in the range of 0.27% to 4% and 6.79% to 20% in the treated and control plots, respectively.
The semi-solid formulation of the present disclosure controlled release paste along with TUTA semiochemical/s was applied in the form of dollops in a tomato field in Kolar, Karnataka for disrupting the mating of Tomato Leaf Miner, Tuta absoluta by 97.8%. This contributed to a substantial yield increase of 45% over control. The fruit damage in treated plot was about 4%, whereas the fruit damage in control was about 38.6%.
The semi-solid formulation of the present disclosure controlled release paste along with DBM semiochemical/s was applied in the form of dollops in cauliflower fields in Maharashtra for disrupting the mating of diamondback moth, Plutella xylostella by 91.67% on an average. Similarly, treatment of controlled release technology (Helio) in chilli fields for the management of Helicoverpa armigera in Gujarat disrupted mating by 95.6%.
All these controlled release paste formulations were found to be non-phytotoxic for selected crops under investigation. The rainfast nature of formulation is tested especially during rainy seasons in the states of Punjab, Gujarath, Maharashtra, Tamilnadu, Andhra Pradesh as well as Telangana regions and precent retention on the plant foliage is found satisfactory more than 80 percent and meeting the amount the active per hectare required to control the pest population during the season long crop cycle.
The release data of the semi-solid formulation of the present disclosure is provided in Figures 1 to 8.
Based on the agricultural field exposure data, the release profile of the semi-solid formulation of the present disclosure with respect to different active at the same level of loading are illustrated in Figures 1-8.
Figure-1 illustrates the effect of active release on agricultural field exposure of Lobesia controlled release paste formulations prepared by using different types of waxes. It is seen from
Figure-1 that at the same level of active loading, effect of wax change is minimal, and they don’t have any effect on active release. The non-effectiveness of wax change is clearly concluded in the formulations prepared by using microcrystalline (MC) wax and rice brain wax exhibiting similar release pattern.
It is seen from Figures 2-3 that active release is sustained up to at least eight weeks, and which may be further extended (more than twelve weeks or three months) due to higher retention of the actives within the formulation, which will be released during further time period.
Figure-4 illustrates the effect of open agricultural field exposure on release of different Scale-up batches of controlled release paste manufactured in commercial scale equipment’s for PBW active. It is seen from Figure-4 that the sustained release duration from PBW formulation is at least three to four months.
.
Figure 5: illustrates the effect of field exposure on the release profile in controlled release paste formulations prepared for different semiochemical/s containing different functional groups with different carbon chain length between C8 to C16 along with functional groups. The formulation characteristics are modulated based on the different vapour pressure and escape rates of different actives containing functional groups are sufficiently demonstrated with controlled release mechanism.
Figure-6: illustrates the effect of field exposure on the release profile in controlled release paste formulations prepared for different semiochemicals containing different functional groups with different carbon chain length between C8 to C16 along with functional groups. The formulation characteristics are modulated based on the different vapour pressure and escape rates of different actives containing functional groups are sufficiently demonstrated with controlled release mechanism.
Figure-7: illustrates the effect of field exposure on the release profile in controlled release paste for prepared by modified microcrystalline wax formulations. The release duration of OFM, LOBESIA, TUTA, TML, RHY and PBW sustain at least up to three months.
Figure-8 illustrates the effect of field exposure on the release profile in controlled release paste formulations prepared by modified rice bran wax formulations with prolonged release of actives to suit the crop period to manage the pest control measures for at least two to three months. Examples of actives extensively studies are FAW, HELIO, PBW and DBM.
The semi-solid formulation of the present disclosure is non-phytotoxic, rain fast, releases semiochemical/s in a controlled release close to zero or first order for season long upto 6 months stable under various environmental conditions, dose dependent release to cover different semiochemical/ss with different crop cycles, uses renewable source of raw materials, and is economical and biodegradable. The preparation and use of natural wax derivatives for controlled and prolonged emission of semio-chemicals, based on the modification of the physicochemical properties of molecules may be able to satisfy the high demand for alternatives insect control in such a way that they provide an emission kinetics adapted to the specific properties of each semiochemical/s.
