Embodiment 1

[0039] Embodiment 1: the processing and embodiment of spinosad and bifenthrin suspension

[0040] Spinosyn 25g, bifenthrin 9g, dispersant 8g, antifreeze agent 4g, thickener 3.5g, defoamer 1g, make up the remaining water to 300g, mix other additives, and mix by high-speed shearing Evenly, add spinosad and bifenthrin, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameters are all below 5mm, and the spinosad and bifenthrin containing plethrin and bifenthrin described in the present invention are prepared. Suspension formulations of insecticidal compositions of pyrethroids.

[0041] Spinosyn 13g, bifenthrin 3g, dispersant 5g, antifreeze agent 2g, thickener 2g, defoamer 1g, make up the remaining water to 100g, mix other additives, and mix evenly by high-speed shearing , add spinosyn and bifenthrin, and grind the balls in a ball mill for 2 to 3 hours, so that the particle diameter is all below 5mm, and the plethyroxine and bifenthrin of the present inve...

Embodiment 2

[0042] Embodiment 2: the processing and embodiment of spinosad and beta-cypermethrin aqueous emulsion

[0043] Spinosad 7g, beta-cypermethrin 4g, emulsifier 3g, solvent 7g, stabilizer 3g, antifreeze 2g, defoamer 1g, thickener 2g, water to make up to 100g. Add the original drug ethyl spinosad and beta-cypermethrin, solvent, emulsifier, and cosolvent together to dissolve into a uniform oil phase; mix part of water, antifreeze, antimicrobial agent and other pesticide auxiliaries in the 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 about half Hours, an oil-in-water emulsion is formed. That is, the aqueous emulsion of the insecticidal composition containing spinosyn and beta-cypermethrin is prepared.

Embodiment 3

[0044] Embodiment 3: the processing and embodiment of spinosad and beta-cypermethrin water-dispersible granules

[0045] Spinosad 9g, beta-cypermethrin 2g, dispersant 4g, wetting agent 4g, disintegrant 3g, filler 70g. Mix spinosad, beta-cypermethrin, dispersant, wetting agent, disintegrating agent and filler evenly, pulverize with ultra-fine jet mill, knead, and then add to fluidized bed granulation dryer for granulation, After drying and sieving, the water-dispersible granules of the insecticidal composition containing spinosyn and beta-cypermethrin of the present invention are obtained through sampling and analysis.

Abstract

The invention relates to a pesticide composition in the field of pesticide combination, wherein the effective ingredients thereof are spinetoram and one of three pyrethroid compounds, the ratio of the two effective ingredients by weight percent is 1 to 80:40 to 0.1, and preferably 3 to 45: 20 to 0.1; the total mass percent of the effective ingredients in the pesticide composition is 1% to 90%, preferably 3% to 50%, the balance is assistant ingredients allowable and acceptable in pesticide preparation, and aqueous emulsion, particle, micro-emulsion, emulsifiable concentrate, suspension, soluble liquid, wettable powder, microcapsule suspension or water dispersible granule can be prepared using known methods; the pesticide combination of the invention can be used for preventing and controlling homopteran and thysanoptera pests such as cnaphalocrocis medinalis guenee, diamondback moth, prodenia litura, cotton bollworm or beet armyworm, thrip, etc.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition compounded with spinosyn and pyrethroid compounds. Background technique [0002] Spinetoram, Spinetoram (XDE-175) is a novel spinosyn insecticide developed by Dow AgroSciences, and it is the second generation product of spinosyn. Spinosyn is an antibiotic insecticide produced by the fermentation of the actinomycete Saccharopolyspora spinosa. It consists of spinosyn A and spinosyn D. Because it has the safety of biological pesticides and the quick-acting properties of chemically synthesized pesticides, it was released in 1999 Received the "President's Green Chemical Challenge Award" in the United States, and began to register more than 100 crops in 24 countries that year. However, although the agent has a good insecticidal effect on vegetable crops, it is not ideal for pest control of crops such as fruits and nuts. But spinosyn has succe...
