Abstract
The invention discloses an herbicidal composition of a paddy field. The herbicidal composition contains active ingredients of a component A and a component B. The component A is metamifop. The component B is benthiocarb or molinate. A mass ratio of the component A to the component B is 1-40: 10-90. The herbicidal composition produces synergism, is mainly used for removing annual weeds in a direct seeding rice field or a transplanted field, is used for preventing and removing gramineous weeds such as barnyard grass and moleplant seed lushly growing in the direct seeding rice field, broadleaf weeds such as Rotala indica, duck tongue and wartwort, and cyperus weeds such as Eleocharis yokoscensis and cyperus difformis. The herbicidal composition has the characteristics of high herbicidal activity, wide herbicide spectrum and convenient use, is safe for rice and is an environment-friendly herbicide.
Description
technical field [0001] The invention belongs to the technical field of pesticide herbicides, in particular to a herbicidal composition for paddy fields. Background technique [0002] Rice is one of the main food crops in my country. Rice 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 rice output accounts for 39.23% of the total grain output. Therefore, the increase or decrease of rice output have a significant impact. However, all kinds of weeds have affected the yield of rice all the time. According to investigations, the loss of rice yield in fields damaged by weeds is generally 10-20%, and serious loss is 40-50%. In recent years, a labor-saving and water-saving planting method of live-seeding rice has risen rapidly, and its weed control is particularly important. Among them, barnyardgrass, stephenia and other gramineous weeds have a greater impact and are more difficult to control, ...
