Abstract
The invention discloses a cyhalofop-butyl containing ternary weeding composition for directly-sown rice fields. The weeding composition contains effective ingredients, wherein the effective ingredients comprise quinclorac, cyhalofop-butyl and metamifop which are in the mass ratio of (1 to 20): (10 to 50): (1 to 10). The weeding composition for the directly-sown rice fields, disclosed by the invention, has a synergistic effect, is mainly used for carrying out spraying on the directly-sown rice fields about 10 days after transplanting so as to prevent and kill off prevailing Gramineae weeds such as Echinochloa crusgalli and Leptochloa chinensis of the directly-sown rice fields and can simultaneously be used for preventing other broad-leaved weeds such as Rotala indica, Monochoria vaginalis and Euphorbia helioscopia and Cyperus weeds such as Eleocharis acicularis and Cyperus difformis. The weeding composition has the characteristics of high weeding activity, wide weed control spectrum and convenience in use and is safe to rice.
Description
technical field [0001] The invention belongs to the technical field of pesticide herbicides, in particular to a ternary herbicide composition for direct-seeding rice fields containing cyhalofop-ethyl. Background technique [0002] Rice is one of the main grain crops in my country. Its sown area accounts for about 18.5% of the country's total sown area, and rice production accounts for 39.23% of the total grain production. Therefore, the increase or decrease of rice production has a decisive impact. But all the time, all kinds of weeds have affected the yield of paddy rice, according to investigation, its paddy paddy yield loss of weed damage field is generally 10-20%, serious loss 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, followed by Broa...
