Definitions

  • the present invention relates to a synergistic insecticidal composition comprising three active components.
  • the present invention also relates to a process for preparing the insecticidal composition and to a method to prevent, control and/or treat insect infestations in plants, plant parts and/or their surroundings by applying the synergistic insecticidal composition.
  • Insect infestations represent a major threat to economically important agricultural crops.
  • the yield of plants for example, fruit, leguminous plants, cucurbitaceae, fibre plants, citrus, vegetables sugarcane, are adversely impacted by insect attack.
  • Chemical control is an important way for preventing and controlling pests in agriculture.
  • current agents show unsatisfactory effects to certain kinds of pests.
  • many pests have developed resistance to commonly used pesticides due to a long term use of the pesticides. Therefore, there is an urgent need to develop new methods and pesticides and/or composition containing them to control these pests.
  • the environmental and economic requirements imposed on modern-day insecticides are continually increasing, with regard, for example, to the spectrum of action, toxicity, selectivity, application rate, formation of residues, and favorable preparation ability. Since there may be problems, for example, with resistances developing to known active compounds, a constant task is to develop new insecticide agents which in some areas at least have advantages over their known counterparts.
  • Thiamethoxam is the common name for 3- [(2-chloro-5-thiazolyl) methyl] tetrahydro-5-methyl-N-nitro-4H-1, 3, 5-oxadiazin-4-imine and has the following chemical formula I:
  • Thiamethoxam is known to have insecticidal activity and is available commercially.
  • Pyrethroids are known insecticides and are synthesized derivatives of naturally occurring pyrethrins, which are taken from pyrethrum, the oleoresin extract of dried chrysanthemum flowers.
  • Ketoalcoholic esters of chrystanthemic and pyrethroic acid account for the insectidial properties of pyethrins. These acids are lipophilic and penetrate insects and paralyze their nervous system (Reigart, et al., 1999) .
  • the insecticidal action of pyrethroid is widely known to be effective against a variety of insect pests in many major crops such as fruits, vegetables, cereals, maize, cotton, soybean, grapes and even on public and animal health sectors.
  • pyrethroids The activity of pyrethroids is both contact and stomach action as a broad spectrum insecticides.
  • synthetic pyrethroids are deltamethrin, lambda-cyhalothrin, fenvalerate, permethrin, cypermethrin, bifenthrin, esfenvalerate, etofenprox, cyfluthrin, fenpropathrin, allethrin, cyphenothrin, flucythrinate, flumethrin, imiprothrin, metofluthrin, prallethrin, resmethrin, silafluofen, sumithrin, tefluthrin, tetramethrin, tralomethrin and transluthrin.
  • Buprofezin is a well-known, readily available pesticide and methods to produce it are known in the art, for example, see U.S. Patent 4,159,328. It is a probable chitin synthesis and prostaglandin inhibitor. It inhibits moulting of nymphs and larvae, eventually leading to death.
  • Enhancements of insecticidal agents and compositions have been achieved to improve control of insect pests and application practice to target crops as single or mixed pesticides.
  • the judicious use of adopting strip application or spot application on areas with high insect incidence only and soil application to avoid direct contact with natural enemies and the use of selective and non-persistent agents increase environmental safety and lower incidence of insect resistance.
  • the adoption of the rotational application of insect control agents with different modes of action contributes to good pest management.
  • Having an insecticidal composition with a high synergistic action with no cross resistance to existing insecticide agents and with a low environmental impact is desirable. Therefore, it would be advantageous to provide a composition, which is potent to insect attack, with physico compatible formulations stable in during storage, safely pack and in ready-to-use formulation.

Description

SYNERGISTIC INSECTICIDAL COMPOSITION
Cross Reference of related application
The present application claims the priority of AU Patent Application No. 2015234288, filed on September 29, 2015, the contents of which are incorporated herein by reference in its entirety.
The present invention relates to a synergistic insecticidal composition comprising three active components. The present invention also relates to a process for preparing the insecticidal composition and to a method to prevent, control and/or treat insect infestations in plants, plant parts and/or their surroundings by applying the synergistic insecticidal composition.
BACKGROUND
Insect infestations represent a major threat to economically important agricultural crops. The yield of plants, for example, fruit, leguminous plants, cucurbitaceae, fibre plants, citrus, vegetables sugarcane, are adversely impacted by insect attack.
Chemical control is an important way for preventing and controlling pests in agriculture. However, current agents show unsatisfactory effects to certain kinds of pests. Furthermore, many pests have developed resistance to commonly used pesticides due to a long term use of the pesticides. Therefore, there is an urgent need to develop new methods and pesticides and/or composition containing them to control these pests. Moreover, the environmental and economic requirements imposed on modern-day insecticides are continually increasing, with regard, for example, to the spectrum of action, toxicity, selectivity, application rate, formation of residues, and favorable preparation ability. Since there may be problems, for example, with resistances developing to known active compounds, a constant task is to develop new insecticide agents which in some areas at least have advantages over their known counterparts.
Thiamethoxam is the common name for 3- [(2-chloro-5-thiazolyl) methyl] tetrahydro-5-methyl-N-nitro-4H-1, 3, 5-oxadiazin-4-imine and has the following chemical formula I:
Figure PCTCN2016100097-appb-000001
Thiamethoxam is known to have insecticidal activity and is available commercially.
However, experience with the single active straight formulation of insecticides worldwide indicates there is a high risk of development of resistant insect subpopulations. Resistance has been reported worldwide in an increasing number of insects active in field crops, fruit, vegetables, and so on.
Pyrethroids are known insecticides and are synthesized derivatives of naturally occurring pyrethrins, which are taken from pyrethrum, the oleoresin extract of dried chrysanthemum flowers. Ketoalcoholic esters of chrystanthemic and pyrethroic acid account for the insectidial properties of pyethrins. These acids are lipophilic and penetrate insects and paralyze their nervous system (Reigart, et al., 1999) . The insecticidal action of pyrethroid is widely known to be effective against a variety of insect pests in many major crops such as fruits, vegetables, cereals, maize, cotton, soybean, grapes and even on public and animal health sectors. The activity of pyrethroids is both contact and stomach action as a broad spectrum insecticides. Examples of synthetic pyrethroids are deltamethrin, lambda-cyhalothrin, fenvalerate, permethrin, cypermethrin, bifenthrin, esfenvalerate, etofenprox, cyfluthrin, fenpropathrin, allethrin, cyphenothrin, flucythrinate, flumethrin, imiprothrin, metofluthrin, prallethrin, resmethrin, silafluofen, sumithrin, tefluthrin, tetramethrin, tralomethrin and transluthrin.
Buprofezin is a well-known, readily available pesticide and methods to produce it are known in the art, for example, see U.S. Patent 4,159,328. It is a probable chitin synthesis and prostaglandin inhibitor. It inhibits moulting of nymphs and larvae, eventually leading to death.
Enhancements of insecticidal agents and compositions have been achieved to improve control of insect pests and application practice to target crops as single or mixed pesticides. The judicious use of adopting strip application or spot application on areas with high insect incidence only and soil application to avoid direct contact with natural enemies  and the use of selective and non-persistent agents increase environmental safety and lower incidence of insect resistance. In addition, the adoption of the rotational application of insect control agents with different modes of action contributes to good pest management. Having an insecticidal composition with a high synergistic action with no cross resistance to existing insecticide agents and with a low environmental impact is desirable. Therefore, it would be advantageous to provide a composition, which is potent to insect attack, with physico compatible formulations stable in during storage, safely pack and in ready-to-use formulation.
SUMMARY OF THE INVENTION
The present invention provides a synergistic insecticidal composition comprising three components (A) buprofezin, (B) thiamethoxam and (C) lambda-cyhalothrin.
The present invention also provides a method to control insect infestations in plants, plant parts and/or their surroundings by applying a synergistic insecticidal composition comprising the above components (A) , (B) and (C) on the plants, plant parts and/or surrounding.
The present invention also provides a process for making a synergistic insecticidal composition containing three components (A) buprofezin, (B) thiamethoxam and (C) lambda-cyhalothrin.
The present invention also provides the use of a synergistic insecticidal composition comprising the above components (A) , (B) and (C) to prevent, control and/or treat insect infestations in plants, plant parts and/or surrounding.
"Plant" as used herein, refers to all plant and plant populations such as desired and undesired wild plants or crop plants.
"Plant parts" as used herein, refers to all parts and organs of plants, such as shoots, leaves, needles, stalks, stems, fruit bodies, fruits, seeds, roots, tubers and rhizomes. Harvested materials, and vegetative and generative propagation materials, for example, cuttings, tubers, meristem tissues, rhizomes, offsets, seeds, single and multiple plant cells and any other plant tissues, are also included.
The word “surroundings” refers to the place on which the plants are growing, the place on which the plant propagation materials of the plants are sown or the place on which the plant propagation materials of the plants will be sown.
“At least one” designates a number of the respective compounds of 1, 2, 3, 4, 5, 6, 7, 8, 9 or more, preferably 1, 2, or 3.
The term “％” generally indicates weight-％if not indicated otherwise.
It has now surprisingly been found that when applying an insecticidal composition comprising three components, namely (A) buprofezin, (B) thiamethoxam and (C) lambda-cyhalothrin on the plants, plant parts and/or their surroundings, for example soybean, dry bean, cotton, vegetable, fruit, citrus and sugarcane, an excellent performance in preventing, controlling and treating insect infestations may be observed. The synergistic insecticidal composition is highly effective for the protection of the aforementioned crops from insect attack.
The synergistic insecticidal composition is found to be highly active against a wide range of pests, i.e., aphids, armyworms, beetles, bollworm, budworms, pickleworm, burrowing bugs, borers, caterpillars, citrus orthezia, Great Southern White, leafhoppers, leafminers, loopers, millipedes, broad mites, moths, spider mites, spittlebug, stink bugs, termite, thrips, weevils, whiteflies, worms, psylla. The present compositions are particular effective against aphids, beetles, bollworm, borers, leafhoppers, moths, spittlebug, stink bugs, termite, thrips, weevils, whiteflies, psylla.
The present invention also demonstrates reduced application cost, increased crop yield and reduced environmental risk. It also essentially prevents the development of and/or delays the dominance of resistant strains of pests, has a broader spectrum of activity and reduces risk of developing resistance.
The present invention also provides a process for using the synergistic insecticidal composition containing the three components buprofezin, thiamethoxam and lambda-cyhalothrin for crop protection. The advantage of the process relates to the propagation of part of plants and especially the seeds, as coated with and/or containing the present synergistic composition.

Biological Examples
A synergistic effect exists with a combination of two or more active compounds when the activity of a composition comprising two or more active compounds is greater than the sum of the activities of each active compounds applied individually. The expected activity for a given combination of two active compounds can be calculated by the so called “Colby equation” (see S.R. Colby, “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations” , Weeds 1967, 15, 20-22) :
whereby:
A ＝ the activity percentage of compound A when active compound A is empolyed at an application rate of m g/ha；
B ＝ the activity percentage of compound B when active compound B is empolyed at an application rate of n g/ha；
E1 ＝ the percentage of estimated activity when compounds A and B are empolyed together at an application rate of m g/ha and n g/ha；
then: E1＝A+B- (A×B/100) .
If the actual activity observed for the combination of compounds A and B is greater than that calculated (E1) , then the activity of the combination is superadditive. In other words, synergism is present.
The expected activity for a given combination of three active compounds can be calculated by the “Colby equation” (S.R. Colby, Weeds 15, 20-22, 1967) , i.e., E＝ (A+B+C) - (A×B+A×C+B×C) /100 + A×B×C/10000
Whereby A ＝ the percent efficacy of compound A when compound A is employed at a dose of m (g/ha) ； B ＝the percent efficacy of compound B when compound B is employed at a dose of n (g/ha) ； C＝ the percent efficacy of compound C when compound C is employed at a dose of p (g/ha) ； E2 ＝ the percent estimated efficacy when compounds A and B and C are employed together at a dose of m (g/ha) , n (g/ha) and p (g/ha) , respectively.
If the actual activity observed for the combination of compounds A, B and C is greater than that calculated (E2) , then the activity of the combination is superadditive. In other words, synergism is present.
