Paddy field weeding composition containing triafamone

Abstract

The invention discloses a paddy field weeding composition containing triafamone. The effective component of the weeding composition is prepared from a component A and a component B, the component A isthe triafamone, and the component B is benthiocarb or molinate; the mass ratio of the component A to the component B is (1 to 40) to (10 to 90). The weeding composition has a synergistic effect, is mainly used for annual weeds of paddy rice direct-seeding fields or transplanting fields, effectively prevents and weeds the annual cyperus rotundus including barnyard grass, paspalum distichum, scirpus planiculmis, fescue, cyperus difformis, leptochloa chinensis, digitaria sanguinalis, yard grass, green bristlegrass, cyperus iria, amaranthus lividus and alopecurus aequalis and the like and has theadvantages that the weeding activity is high, the weed control spectrum is wide, and use is convenient; moreover, the weeding composition is safe to paddy rice and is an environment-friendly weed killer.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a paddy field herbicide composition containing fluoroketone sulfentrame. 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 ...
