Problems solved by technology

[0002] In recent years, the phenomenon of diseases and insect pests harming the growth of vegetables has become more and more serious, and the application of pesticides has had little effect. Because the cabbage caterpillar has developed resistance, the amount and frequency of pesticide use have to increase year by year. It is a very urgent task to control and control cabbage caterpillar with low toxicity and high efficiency

Embodiment Construction

[0008] Take 1.5% of the original drug lambda-cyhalothrin, 8.5% of the original drug chlorpyrifos, 8% of the 2204 emulsifier, and 82% of the solvent xylene, and put them into the reaction pot and stir them for 60 minutes to dissolve until they are uniform, and take samples for analysis Conform to the technical index of the present invention:

[0009] Cyhalothrin%(m / m) ≥1.5

[0010] Chlorpyrifos%(m / m) ≥8.5

[0011] Moisture %(m / m) ≤0.5

[0012] Acidity (in H 2 SO 4 Count)%≤0.5

[0013] Emulsion Stability Passed

[0014] Cold storage and hot storage stability Pass

[0015] Afterwards, it is pumped into the settling tank and high-level tank, and after being filtered by the filter, it becomes a packable product.

[0016] The present invention has been proved by field efficacy tests (field test report is attached), and has the characteristics of fast knockdown, long-lasting effect and good control effect on preventing and controlling cabbage caterpillar.

Abstract

The invention relates to a chlorpyrifos*highly effective lambda-cyhalothrin emulsifiable concentrate (EC), which is composed of a technical product of highly effective lambda-cyhalothrin, a technical product of chlorpyrifos, emulsifier (2204 type) and solvent of xylene which are compounded together. Field drug efficacy experiments prove that the agricultural chemical can effectively prevent and control the harm of cabbage worms to the growth of vegetables (for example, celery cabbage), causes no toxic danger to vegetables, human and livestock, the production cost of the vegetables can be reduced, and the vegetable supply to inhabitants can be guaranteed.

Description

technical field [0001] The invention relates to a pesticide for preventing and controlling vegetable pests, in particular to a chlorpyrifos-cyhalothrin emulsifiable concentrate. Background technique [0002] In recent years, the phenomenon of pests and diseases harming the growth of vegetables has become more and more serious, and the application of pesticides has had little effect. Because the cabbage caterpillar has developed resistance, the amount and frequency of pesticide use have to increase year by year. It is a very urgent task to develop low-toxicity and high-efficiency pesticides for controlling cabbage caterpillars. Contents of the invention [0003] The object of the present invention is to provide a kind of chlorpyrifos·beta-cyhalothrin emulsifiable concentrate for above-mentioned situation, it is characterized in that adopting the original drug beta-cyhalothrin 0.5%-10%, the original drug chlorpyrifos 5%-50%, emulsified Agent (2204 type) 8%, solvent xylene 3...
