Abstract

The invention discloses a paddy direct sowing field ternary weeding composition. Effective components of the weeding composition are composed of anilofos, simetryne and mesotrione. The mass ratio of the anilofos to the simetryne to the mesotrione is 10-30:10-30:1-10. The paddy direct sowing field weeding composition has the synergism, is mainly used for being sprayed about ten days after paddy direct sowing field transplanting, and preventing and removing barnyard grass, moleplant seeds and other gramineous weeds prevailing in the paddy direct sowing field and can also be used for preventing other rotala indica, monochoria vaginalis, euphorbia helioscopia and other broad leaf weeds and eleocharis yokoscensis, cyperus difformis and other cyperaceae weeds. The paddy direct sowing field ternary weeding composition has the beneficial effects of being high in weeding activity, wide in herbicide controlling spectrum and convenient to use, safety is achieved for paddy, and the paddy direct sowing field ternary weeding composition belongs to an environment-friendly weed killer.

Description

technical field

[0001] The invention belongs to the technical field of pesticides and herbicides, and particularly relates to a herbicidal composition for controlling weeds in direct seeding fields of rice, which is composed of sedge phosphine, citrozin and mesotrione. Background technique

[0002] Rice is one of the main food crops in my country and is the staple food of about 60% of the country's population. Its sown area accounts for about 18.5% of the country's total sown area, and the rice yield accounts for 39.23% of the total grain output. significant impact. But all the time, all kinds of weeds have affected the yield of rice. According to the survey, the loss of rice yield in the fields damaged by weeds is generally 10-20%, and the serious loss is 40-50%. In recent years, a labor-saving and water-saving planting method of direct seeding rice has emerged rapidly, and its control of weeds is particularly important. Among them, the most influential and difficult to con...
