FIELD OF THE INVENTION
The present invention relates to a pesticidal composition and more particularly to
a synergistic pesticidal composition comprising Diafenthiuron, and Emamectin or
its salts.
BACKGROUND OF THE INVENTION
It is observed very often, that prolonged usage of pesticides leads to development
of resistance by pests which make the pesticide ineffective. This results in
application of pesticide compositions in higher doses which is detrimental to the
environment.
A significant obstacle faced by the researchers in this technical field is regarding
pesticide activity. For protection of crops it is vital that biological activity of the
pesticides should be improved and also that the activity should be persistent over a
period of time.
Hence, there is a need to develop a composition which addresses the problem of
resistance and soil toxicity and also is used at reduced dosages, controls
environmental damage, offers broader crop protection spectrum, improved and
healthy foliage, rainfastedness, improved crop yield, saves labour and controls
various insects and pests, improves plant growth and is yet cost-effective to the
end user.
Prior art patent application EP0736252 discloses the combinations of
diafenthiuron with other insecticides. The patent application EP 0736252 A2
discloses the list of several insecticides that can be used in combination with
Diafenthiuron. However it does not teach or provide the particular combination of
Diafenthiuron and Emamectin or its salts thereof nor does it discloses the
concentration ranges and the ratios of Diafenthiuron and Emamectin which show
synergistic effect and hence preclude high loading of harmful pesticides.
A pesticidal composition must satisfy a range of requirements to be viable on the
market. One such requirement of the pesticidal composition is the ability to be
selective in biological action and have low toxicity and a high margin of safety to
humans, crops, economic animals, aquatic organisms and birds. Another
1011/PAT APPLN/13
3
requirement is the desire that the composition should be environmental-friendly in
that there should be demonstrably low impacts on the environment. Further, there
should be none or little insect resistance to such compounds or combinations.
In a view of afore mentioned there is a need for preparing synergistic pesticidal
compositions comprising effective amounts of Emamectin and Diafenthiuron
which provide improved efficacies at lower concentration compared to that
observed with the individual components.
Certain mixtures of active ingredients are proposed in the literature for controlling
pests. However, the biological properties of these mixtures of known compounds
are not entirely satisfactory in the field of pest control, which is why there is a
demand for providing further mixtures having synergistic pesticidal properties, in
particular for controlling insects and representatives of the order Acarina. This
object is achieved according to the present invention by providing the present
composition.
The invention relates to a pesticidal composition which comprises a pesticidallysynergistically
active combination, in variable proportions, of the pesticidally
active compound Diafenthiuron (CAS-Number: 80060-09-9), in free form or in
the form of an agro chemically acceptable salt.
Diafenthiuron, mainly protects crops, fruits, vegetables, cotton, tea and
ornamental plants from aphids, whiteflies, leafhoppers, has high control effect on
the already resistant diamondback moth and grey armyworm and has a specific
control effect on spider mite. It has excellent contact and stomach action, and
good penetration ability. It is a pro-insecticide, which has to be converted to its
active from, before it can act on an insect. The active compound then acts on the
energy-producing enzymes in the mitochondria. This results in immediate
paralysis of the pest after intake or contact with the product. Notably,
Diafenthiuron is also safe for predators, earthworms and birds.
Emamectin (CAS-Number: 155569-91-8) is a mixture of mixture of ≥ 90%
(10E,14E,16E)-(1R,4S,5′S,6S,6′R,8R,12S,13S,20R,21R,24S)-6′-[(S)-sec-butyl]-

hexapyranoside benzoate and is described as MK-244 in Journal of
Organic Chemistry, Vol. 59 (1994), 7704- 7708. Salts of Emamectin that are
especially valuable agrochemically are described in US-P-5,288,710. Emamectin
works as a chloride channel activator by binding gamma aminobutyric
acid (GABA) receptor and glutamate-gated chloride channels disrupting nerve
signals within arthropods. The compound stimulates the release of GABA from
the synapses between nerve cells and while additionally increasing GABA’s
affinity for its receptor on the post-junction membrane of muscle cells in insects
and arthropods. The stronger binding of GABA increases the cells permeability to
chloride ions within the cell due to the hypotonic concentration
gradient. Neurotransmission is thereby reduced by subsequent hyperpolarisation
and the elimination of signal transduction.
Diafenthiuron is available in form of 50% wettable powder, whereas Emamectin
(Benzoate) is generally formulated as 5% soluble granules and 1.9% emulsifiable
concentrate. Hitherto, there have been no studies to determine the mostefficacious
and synergistic ratios of these two pesticides to achieve efficacious
insect control. Hence there is a need in the art for a synergistic pesticidal
composition comprising these pesticides.
SUMMARY OF THE INVENTION
The present invention relates to a synergistic pesticidal composition for wide
spectrum control of insect pests, delaying the emergence of the resistant strains of
the insect-pests, minimizing the risk of development of resistance, and achieving
effective and economical control of undesired insect-pests.

form of a suspension concentrate (SC).
DETAILED DESCRIPTION OF INVENTION
Discussed below are some representative embodiments of the present invention.
The invention in its broader aspects is not limited to the specific details and
representative methods. The illustrative examples are described in this section in
connection with the embodiments and methods provided. The invention according
to its various aspects is particularly pointed out and distinctly claimed in the
appended claims read in view of this specification and appropriate equivalents.
It is to be noted that, as used in the specification and the appended claims, the
singular forms "a", "an" and "the" include plural referents unless the context
clearly dictates otherwise. Thus, for example, reference to a composition
containing “a compound” includes a mixture of two or more compounds. It should
also be noted that the term “or” is generally employed in its sense including
“and/or” unless the content clearly dictates otherwise.
The expression of various quantities in terms of “% w/w” or “%” means the
percentage by weight, relative to the weight of the total solution or composition
unless otherwise specified.
The term "agrochemically effective amount" is that quantity of active agent,
applied in any amount which will provide the required control of insect pests and
diseases. The particular amount is dependent upon many factors including, for
example, the crop, pest and disease sought to be controlled and environmental
conditions. The selection of the proper quantity of active agent to be applied,
however, is within the expertise of one skilled in the art. Further, the term “active
1011/PAT APPLN/13
7
ingredient” (A.I.) or “active agent” used herein refers to that component of the
composition responsible for control of insect pests.
Compositions comprising a single insecticidally active component suffer from
numerous drawbacks such as development of resistant insect species, requirement
of high amount and concentration of the active ingredient, environmental damage,
seepage of the active component into ground water, phyto-toxicity and harmful
effects on the health of animals and humans.
Accordingly, the inventors of the present invention have developed a synergistic
pesticidal composition comprising Diafenthiuron; and Emamectin or its salt such
as Emamectin benzoate, wherein the mass ratio between Diafenthiuron, and
Emamectin or its salts ranges from 1:16 to 1:50. The pesticidal composition
contains about 30.00% of Diafenthiuron, and Emamectin, or its salt such as
Emamectin benzoate, is present in an amount in the range from 0.60 to 1.90%.
The synergistic pesticidal composition, further comprises excipients selected from
the group consisting of anti-freezing agent, dispersing cum wetting agent,
defoamer, biocide, thickener, water and combinations thereof, and the
composition is in the form of a suspension concentrate (SC). The term
“suspension concentrate” used herein refers to a suspension of the active pesticide
and excipients in a small quantity of liquid, usually water. A composition in the
form of a suspension concentrate is user friendly and affords a reduced risk of
occupational exposure.
An anti-freezing agent is generally added to pesticidal compositions, to prevent
the aqueous compositions from freezing. Suitable anti-freezing agents useful
herein, but not limited to, include propylene glycol, Diethylene glycol (DEG),
Mono ethylene glycol (MEG) and combinations thereof. Preferably, the antifreezing
agent is present in an amount in the range from 1.00-8.00%.
A dispersing cum wetting agent is another important component of a suspension
concentrates as it facilitates the formation of a suspension of a water insoluble
substrate in water. Non-limiting examples of dispersing cum wetting agent that
can be used in the present invention include non-ionic surfactants and amine salt
of phosphate tristyryl phenol ethylated, acrylic copolymer, ethoxylated
1011/PAT APPLN/13
8
polyarylphenol phosphate ester, each of which can be used individually or in
combination, in an amount in the range from 2.00-10.00%.
A defoamer, also called as anti-foam, is generally added to a pesticidal
composition as foam formation prevents the efficient filling of a container.
Preferably, the defoamer is dimethyl polysiloxane emulsion and present in an
amount in the range from 0.01-0.50%.
The synergistic pesticidal composition may contain a biocide selected from the
group consisting of Proxel GXL, formaldehyde and combinations thereof, and
present in an amount in the range from 0.01-0.50%. Proxel GXL is a broad
spectrum biocide for the preservation of industrial water-based products, such as
the composition of the present invention, against spoilage from bacteria, yeasts
and fungi.
It is necessary to add a thickener to a pesticidal composition to reduce the
tendency of the pesticide composition to disperse when sprayed, and decrease the
likelihood of it being rinsed off of the crops. Preferably, the synergistic pesticidal
composition comprises xanthan gum as thickener in an amount in the range from
0.10-0.50%.
It has been surprisingly found that the synergistic pesticidal composition of
present invention provides a wide spectrum control of insect pests, delaying the
emergence of the resistant strains of the insect-pests, and achieving effective and
economical control of undesired insect-pests.
The embodiments of the present invention are more particularly described in the
following examples that are intended as illustrations only, since numerous
modifications and variations within the scope of the present invention will be
apparent to those of skill in the art. Unless otherwise noted, all parts, percentages
and ratios reported in the following examples are on a weight basis and all
reagents used in the examples were obtained or are available from the chemical
suppliers.

Process for preparing synergistic pesticide composition in the form of
Suspension Concentrate (SC)
The synergistic insecticidal compositions of Examples 1-3 are prepared by the
process depicted in Figure 1. All the raw materials were verified for conformance
to the laid down individual specifications. The raw materials required for
Examples 1, 2, and 3 are illustrated in table 2 under the column headings 1, 2, and
3 respectively. Entries for Emamectin Benzoate and Diafenthiuron in table 2 differ
from those in table 1 as entries in table 1 are for 100% pure compounds, whereas
those in table 2 are for technical ones, i.e. the ones containing a certain percentage
of impurities.
The amounts of active ingredients presented in table 2 may be greater than the
values calculated taking into account the percentage purity of the active
ingredients, to compensate for losses of said ingredients during the manufacturing
process. It was observed that following said procedure on industrial scale the final
yield of A.I. will be similar or same as to standardized values.
The required quantities of raw materials as illustrated in Table 2 below, were
weighed, and transferred through the auto-batching system. The dispersing cum
wetting agent is first diluted in demineralized (D.M.) water and solubilized by
high shear mixing, and then added along with required quantities of anti-freezing
agent, Emamectin benzoate technical, deformer and Diafenthiuron technical, into
a premixing vessel, to make a homogeneous mass. Thereafter, the homogenous
mass was ground to a mean particle size of 3-5 microns in a bead mil and mixed
with 2% aqueous solution of xanthan gum under low stirring. Further, the quality
of in-process sample was checked for conformance to the laid out specifications.
Finally, the quality approved in-process sample was transferred to the holding
tank after passing through sparkler filter pump for packing as per the
requirements.

The aforementioned trial results indicate that a composition in the form of a
Suspension Concentrate (T4) comprising Diafenthiuron (30%) and Emamectin
Benzoate (1.9%) is most effective against all the target insects as specified in the
table above. Additionally, this composition results in lower shoot & fruit damage,
better crop condition i.e. fresh green leaves and better yield. Similar effects were
found in the case of a composition in the form of a suspension concentrate (T1)
comprising Diafenthiuron (30%) and Emamectin Benzoate (0.6%) and the one
(T2) comprising Diafenthiuron (30%) and Emamectin Benzoate (1.1%).
Commercially available reference products failed to show any significant effect.
The phytotoxic effect of different treatment schedules were also observed in ten
randomly selected plants from each plot on 0-10 scale (Table 6) for yellowing,
stunting, necrosis, epinasty hyponasty etc. Observations were recorded on 1, 3, 7,
