Composition containing thiazophosphine and acetoallin and application thereof

Abstract

The invention discloses composition containing fosthiazate and ethylicin and an application of the composition. The composition contains active ingredients and auxiliaries, wherein the active ingredients are fosthiazate and ethylicin in the weight ratio of (1:20)-(15:1). According to the composition, defects of small selection range, high probability of decomposition and instability of conventional pesticide (cartap) are effectively overcome, the fosthiazate permeability is enhanced, the control effect is good, the use amount of the fosthiazate for each mu is remarkably reduced and can be lower than 20 g, the inhibition effect of fosthiazate on rice seed germination is relieved, and the pesticide use safety is improved.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a composition containing thiazophosphine and acetoallin. Background technique [0002] Rice apical nematode disease occurs in all countries in the world. It was introduced from Japan to the suburbs of Tianjin in 1940, and then gradually expanded to all major rice areas in the country with the transportation of rice seeds. Among them, it occurred in some areas of Zhejiang, Jiangsu, Shandong, Yunnan and other provinces. heavier. Due to long-term neglect of the prevention and control of rice apical nematode disease, in 2002, a large-scale outbreak of "small spikes" in the main japonica rice varieties Wuyujing No. 2 and Wuyunjing No. 7 in Jiangsu Province caused serious damage to rice production. harm. [0003] When rice is infected with bakanae disease, the plants will grow wildly. The diseased plants are often more than 50% taller than normal plants, and the seed setting rate is greatly...

AI Technical Summary

Problems solved by technology

[0004] Existing agents for the prevention and control of bakanae or bakanae disease have been used for many years, and there is already a problem of strong drug resistance that leads to a decline in the control effect

At the same time, some commonly used drugs, such as cartap, due to their special physical and chemical properties, the compounded formulations of medicaments and other medicaments are limited to a few formulations such as wettable powder, and are easy to decompose, resulting in a decline in the control effect

The dosage of existing medicines is relatively large, which generally needs to reach 200-300 g / mu, which further leads to two problems: the phytotoxicity occurs, which leads to a decrease in the germination rate of rice; the second is that the cost of medicines is too high, and users are unwilling accept
