Problems solved by technology

[0011] At present, my country's emulsifiable concentrate accounts for about 50% of the total production of preparations. The proportion of wettable powder, granule, soluble powder and other dosage forms is relatively small, and the proportion of other new dosage forms is even smaller. The existing pesticide dosage form structure is very unreasonable.

Abstract

The invention discloses a compound composition for preventing and treating rice planthopper, relating to biodiesel cream and suspending agent containing pymetrozine and thiamethoxam. The invention has better desinsection effect on pests such as rice planthopper and the like, and the activity thereof has obvious synergy compared with the activity of one-component. The invention obtains optimized formula by tests, has long lasting effect of the medicine, slows down the generation of resistibility, has small amount of pesticide residue, has no pollution to crops, has high safety, and accords with the safety requirements of pesticide preparation. Comparatively speaking, the invention reduces the usage of single dosage, reduces medicine cost, and improves economic and ecological benefits.

Description

1. Technical field [0001] The invention discloses a compound composition for controlling pests such as rice planthopper, and relates to active ingredients containing insecticides such as pymetrozine and thiamethoxam. The invention also discloses a method for using the compound composition to protect crops against harmful organisms, which can produce a higher insecticidal effect than each active component when used alone, and has a synergistic effect. The compound composition is effective on both adult insects and nymphs of pests, has strong quick-acting effect after use, long-lasting effect period and the like. [0002] The invention belongs to the field of agricultural chemicals. 2. Background technology [0003] 1. The need to control pests such as rice planthoppers [0004] Rice planthoppers include brown planthopper, brown planthopper, white-backed planthopper, etc., which mainly harm rice and often cause devastating disasters. And can spread rice virus disease. Rice...
