Embodiment Construction

[0007] Take 4% of the original drug chlorpyrifos, 16% of the original drug phoxim, 8% of (0204C) emulsifier, and 72% of the solvent xylene and put them into the reaction pot after being measured by the metering tank, and stir for 60 minutes until they are uniformly dissolved. Technical index of the present invention:

[0008] Chlorpyrifos%(m / m) ≥4

[0009] Phoxim%(m / m) ≥16

[0010] Moisture %(m / m) ≤0.5

[0011] Acidity (in H 2 SO 4 Count)% (m / m) ≤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 filtered by the filter to become a packable product.

[0015] Field drug efficacy tests prove that the present invention has the characteristics of fast knockdown, long duration and good control effect against resistant rice leaf rollers. A field test report is attached.

Abstract

The invention relates to a chlorpyrifos*phoxim emulsifiable concentrate, which is composed of a technical product of chlorpyrifos, a technical product of phoxim, emulsifier (0204C), and solvent of xylene which are compounded together. Field drug efficacy experiments prove that the agricultural chemical has strong permeation in the use for preventing and controlling the grass leaf rollers, the knockdown speed is quick, the duration is long, the poisoning phenomenon does not exist, and thereby the agricultural chemical is favorable for reducing the production cost of rice and increasing the income of peasants.

Description

【Technical field】 [0001] The invention relates to a pesticide for controlling rice leaf roller pests, in particular to a chlorpyrifos-phoxim emulsifiable concentrate. 【Background technique】 [0002] In recent years, rice leaf roller pests have occurred frequently, and the use of organophosphorus pesticides alone has increased year by year. The rice leaf roller has developed resistance to some organophosphorus pesticides to varying degrees. The results are minimal, resulting in poor rice harvests, increased production costs, and environmental pollution. It is an urgent task to develop a high-efficiency, low-toxicity, quick-acting medicament that can control rice leaf rollers. 【Content of invention】 [0003] The object of the present invention is to provide a kind of chlorpyrifos · phoxim emulsifiable concentrate for the drawback of above-mentioned pesticide, it is characterized in that is made of former drug chlorpyrifos 4%-45%, phoxim 10%-50%, emulsifier (0204C) 8% , Sol...
