Application of a synergistic combination of silwet 806 and chloromyron as an adjuvant for the control and control of fenoxaprop-methyl in Japan

Abstract

The invention discloses a synergistic combination of Silwet 806 and chlorotoluron as an adjuvant for controlling resistant weeds and its application. At the same time, it has the advantages of being safe to wheat; significantly reducing the amount of application and reducing the cost of chemical control; it can also control other resistant gramineous weeds and some broad-leaved weeds in winter wheat fields, and reduce the frequency of application. It is a combination of synergistic and volume-reducing herbicide adjuvants that is currently feasible for the control of winter wheat fields against fenoxaprop-methyl.

Description

technical field

[0001] The invention belongs to the technical field of plant protection, and relates to a synergistic combination of adjuvant Silwet 806 and chlorotoluron, which is used to prevent and control the fenoxaprop-ethyl japonica in winter wheat fields. Background technique

[0002] Wheat is a crop widely planted all over the world. It is one of the most important food crops in the world, and its yield is second only to corn. About 40% of the world's population uses wheat as their main food. According to statistics, the total sown area of ​​wheat in my country in 2017 was 23.9875 million hectares, and the total wheat output was 129.774 million tons, accounting for 21.38% of the country's total grain sown area and 21% of the country's total grain output.

[0003] In the middle and lower reaches of the Yangtze River plain rice stubble wheat field, A. japonica is one of the most serious damage and widely distributed gramineous weeds. Studies have shown that the density...
