Problems solved by technology

[0002] In recent years, rice stem borer pests have become more and more serious during rice growth. When organophosphorus pesticides are used alone, stem borer has developed resistance to some organophosphorus pesticides to varying degrees. The amount and frequency of use are increasing year by year. little effect

Embodiment Construction

[0007] Take 12% of the original drug malathion, 8% of the original drug triazophos, 8% of the 0201 type emulsifier, and 72% of the solvent xylene, put them into the reaction pot after being measured by the metering tank, and stir for 60 minutes to dissolve until uniform. Sampling analysis meets technical index of the present invention:

[0008] Malathion%(m / m) ≥12

[0009] Triazophos % (m / m) ≥8

[0010] Moisture %(m / m) ≤0.5

[0011] Acidity (in H 2 SO 4 Count)%≤0.5

[0012] Emulsion Stability Passed

[0013] Cold storage and hot storage stability Pass

[0014] Then it is pumped into the settling tank and high-level tank, and after being filtered by the filter, it becomes a packable product.

[0015] The present invention has been proved by the field efficacy test (the field efficacy test report is attached), and has the characteristics of fast knockdown, long duration and good control effect for preventing and controlling the stem borer.

Abstract

The invention relates to a malathion*hostathion emulsifiable concentrate, which is composed of a technical product of malathion, a technical product of hostathion, emulsifier (0201 type) and solvent of xylene which are compounded together. Field drug efficacy experiments prove that the agricultural chemical can effectively control the harm of rice stem borers to the growth of rice, and has strong permeation, the persistence period can reach about 20 days, the production cost of rice can be reduced, the income of peasants can be increased, and the severe environment pollution can be avoided.

Description

【Technical field】 [0001] The invention relates to a pesticide for controlling rice stem borer pests, in particular to a pesticide for malathion-triazophos emulsifiable concentrate. 【Background technique】 [0002] In recent years, rice stem borer pests have become more and more serious during the growth of rice. When organophosphorus pesticides are used alone, stem borer has developed resistance to some organophosphorus pesticides to varying degrees. The amount and frequency of use are increasing year by year. had little effect. There is an urgent need to develop a high-efficiency, low-toxicity, and control-resistant chemical borer agent. 【Content of invention】 [0003] The object of the present invention is to provide a malathion-triazophos emulsifiable concentrate in response to the above-mentioned needs, which is characterized in that 5%-50% of the original drug malathion, 5%-50% of the original drug triazophos, emulsified Agent (0201 type) 8%, solvent xylene 30%-75%, ...
