Problems solved by technology

It has a very outstanding control effect on larvae. The disadvantage is that it has limited control effect on adults, no ovicidal effect, and weak systemic conduction effect.
[0006] Long-term use of one type of insecticide will easily lead to insect resistance, which will increase the amount of insecticide used, kill a large number of natural enemies of pests, increase the cost of insecticide, and pollute the environment, resulting in high toxicity, large dosage, large residues, and poor efficacy.
Reasonable mixing of pesticides with no cross-resistance and different mechanisms of action is a relatively simple means to solve the above problems, and the development cycle is short and harmless to the environment. The dual compounding of cyanamide and benzamide insecticides in a certain proportion has obvious synergistic effect, and the dosage is less, the control effect is high, and it is more environmentally friendly, and the compounding of these two types of pesticides has not been reported so far

Embodiment approach

[0015] In the following embodiments, component A is selected from sulfoxaflor, and component B is selected from any one of chlorantraniliprole, bromantraniliprole, flubendiamide, chlorantraniliprole, and flonicamid.

[0016] In one of the technical solutions of the present invention, the insecticidal composition is an emulsion in water, and the weight percentage of the components is:

[0017]

[0018] The specific production steps of the emulsion in water are as follows: first, the original medicine A and B, solvent, emulsifier, and cosolvent are added together to dissolve into a uniform oil phase; Pesticide auxiliaries are mixed together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearer for high-speed shearing, and add the remaining water , cut for about half an hour to form an oil-in-water emulsion. A water emulsion of the compo...

[0050] (1) Test drug

[0051] 96% sulfoxaflor technical substance, 95.3% chlorantraniliprole technical substance, all of which are provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0052] Dissolve the original drug with acetone first, and mix the appropriate amount of the two original drugs into 5 different ratios according to the results of the preliminary experiment, and then use acetone to dilute each treatment into 5 series of concentration gradients for use.

[0053] (2) Test target

[0054] Rice planthopper. The brown planthopper was used as the test object. The insect species were taken from the paddy fields of Dalu Village, Zhaodian Town, Gaoqing County. They were artificially raised for multiple generations in the insect culture room, and the healthy and consistent 4-5 instar nymphs were selected for future use.

[0055] (3) Test method

[0056] The spot method recommended by NY / T1154.1-2006 was used for determination. Clean the micro-dropper with sol...

[0082] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, wherein the synergistic effect of sulfoxaflor: chlorantraniliprole is 8:2 The effect is the most obvious, and the co-toxicity coefficient is 147.94. The test results showed that both sulfonicafran and chlorantraniliprole...

Abstract

A pesticidal composition in the field of composite pesticides is disclosed in the invention. The effective components of the pesticidal composition comprise sulfoxaflor and amide pesticides, wherein, the weight ratio of sulfoxaflor to amide pesticides is 1-80:80-1, preferred 1-45:35-1. The total content of the effective components accounts for 1-90wt% of the pesticidal composition, preferred 1-50%, and the rest are auxiliary components which are allowed and accepted in pesticides. The pesticidal composition can be prepared into dosage forms, such as missible oil, suspending agent, wettable powder, water dispersible granule, emulsion in water and micron emulsion by known methods, and has substantial effects on controlling Lepidopterous pests such as diamondback moth, beet armyworm, prodenia litura, cotton bollworm, Chilo suppressalis, mealybugs and the like, and homopteran pests with piercing-sucking mouthparts such as plant hopper, aphid, whitefly, leafhopper and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, and relates to a dual compound insecticidal composition using sulfoxaflor and amide compounds as active ingredients. Background technique [0002] Sulfoxaflor, its chemical name: [1-6-(trifluoromethyl)pyridin-3-yl]ethyl]-λ4-mercaptocyanamide; molecular formula: C 10 h 10 f 3 N 3 OS, the structural formula is: [0003] [0004] Sulfoxaflor is a sulfonylimide insecticide that acts on a unique binding site in the choline receptor to exert insecticidal function. It can be absorbed into plants through leaves, stems and roots. Sulfoxaflor is suitable for the control of cotton bugs, aphids, whiteflies, planthoppers and scale insects, etc.; it is efficient, fast and has a long residual effect, and can effectively control neonicotinoids, pyrethroids, organophosphorus and amino acids. Formate pesticides produce resistant sap-sucking pests. It has the advantages of fast onset of acti...
