Problems solved by technology

[0009] Using the above agents alone has the disadvantages of relatively high cost, poor quick-acting or persistent effect, etc.
In order to develop pesticides with good quick-acting and long-lasting effects and low cost, we screened clothianidin and benzoylurea compounds on the basis of indoor screening and field experiments, which have obvious synergistic effects , and no relevant reports have been found so far

Embodiment approach

[0018] One of the technical solutions of the present invention, the insecticidal composition is an aqueous emulsion, and the weight percent of the component is:

[0019] Active ingredient A 1~80%

[0020] Active ingredient B 1~80%

[0021] Emulsifier 3~30%

[0022] Solvent 5~15%

[0023] Antimicrobial agent 0.1~1%

[0024] Stabilizer 2~15%

[0025] Antifreeze 2~5%

[0026] Defoamer 0.1~8%

[0027] Thickener 0.2~2%

[0028] water balance

[0029] The specific production steps of the water emulsion are as follows: first, add the original drug A and B, the solvent, the emulsifier and the cosolvent together to dissolve into a uniform oil phase; add part of the water, antifreeze, antimicrobial agent and other other The pesticide adjuvants 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 reaching the phase inversion point, turn on the shearing machine for high-speed she...

example 1

[0085] (1) Test drug

[0086] 96% Thiafenamide technical drug, 94% Hexaflumuron technical drug, the above technical drugs are all provided by Qingdao Hailier Pharmaceutical Group R&D Center.

[0087] (2) Test target

[0088] Helicobacter bollworm reared for generations indoors, indoor conditions: temperature (28±2)℃. The relative humidity is 70%±5%, and the light cycle is 16 / 8h (L / D).

[0089] (3) Test method

[0090] In this experiment, the insect body immersion method was used. First, the mother solutions of clothianidin and hexaflumuron were diluted to 5 concentrations, which were respectively placed in beakers for use. Use a writing brush to gently sweep the larvae of cotton bollworm in the early stage of the third instar with the same physiological state into the dipping device, immerse the dipping device in the medicinal solution, shake it gently, take it out after 5s, and quickly wash the worm body with absorbent paper and dry it. Surrounding the excess liquid medi...

[0107] (1) Experimental drug to be tested

[0108] 96% thiamethoxam technical, 95% diafenthiuron technical, all the above-mentioned technical medicines are provided by Qingdao Hailier Pharmaceutical Group.

[0109] According to the pre-experiment, the total active ingredients of the two were set to be 20%, and the set ratios were m (thiananilamide): m (hexflumuron), which were 5: 15, 8: 12, 10: 10, 12: 8, 15: 5.

[0110] (2) Test target

[0111] Helicobacter bollworm reared for generations indoors, indoor conditions: temperature (28±2)℃. The relative humidity is 70%±5%, and the light cycle is 16 / 8h (L / D).

[0112] The experimental method is the same as the activity measurement example 1

Abstract

The invention relates to a pesticide composition in the field of pesticide compounding, which comprises the active ingredients of thiacloprid amide and benzoyl urea compounds, the balance of allowable and acceptable auxiliary ingredients, wherein the weight percentage of the two active ingredients is 1-80:80-1, preferably 1-40:40-1; and the total mass percentage of the active ingredients in the pesticide composition is 1 to 90 percent, preferably 10 to 50 percent. The pesticide composition can be prepared into a water emulsion, a microemulsion, missible oil, a suspension, wettable powder and a water dispersible granule by using known methods. Moreover, the thiacloprid amide and an anabasine pesticide are taken as active ingredients to control rice leaf roller, diamondback moth, spodoptera litura, cotton bollworm or beet armyworm, thrips and other homoptera and thysanoptera pests.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a two-component insecticidal composition with clothianidin and a benzoyl urea compound as active ingredients. Background technique [0002] Clothianidin, test code JS9117, is a new type of o-heterocyclic benzamide compound created and discovered by Jiangsu Pesticide Research Institute Co., Ltd. in 2009. The chemical name is 3-bromo-N-{4-chloro-2-methyl yl-6-[2-(5-amino-1,3,4-thiadiazole)]phenyl}-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxamide [1] , It has high activity on lepidopteran insects such as diamondback moth, beet armyworm, armyworm, cotton bollworm, and diploid borer. The structural formula is: [0003] [0004] Lufenuron, chemical name: RS)-1-[2,5-dichloro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]-3-(2, 6-Difluorobenzoyl) urea, molecular formula: C 17 H 8 C 12 F 8 N 2 O 3 , acts on insect larvae, prevents the peeling process and kills pests,...
