Problems solved by technology

[0002] In recent years, the resistance of barnyardgrass in water-seeded rice fields has become stronger and stronger. In the middle and lower reaches of the Yangtze River and Northwest China, a resistant barnyardgrass has appeared in an increasing area. This barnyardgrass has a very strong tillering ability. After that, common rice field herbicide ingredients such as cyhalofop-methyl, fenpyramid, bispyribac, and quinclorac were basically ineffective against it.

Embodiment 2

[0101] Biological Example 2 Field Test of Controlling Weeds in Water Seeded Rice Fields

[0102] In Yanxi Village, Taoyuan County, Changde, Hunan Province, the efficacy test of 50% cyhalofop-methyl, fenpyramid, propanil suspoemulsion (20:5:25) in the control of water-seeded annual grass weeds in Example 3 was carried out. The control effect, effective dosage and safety of the agent on rice field weeds were verified. The experimental crop is water-seeded rice, the rice variety is hybrid early rice, and the control object is barnyardgrass ( Echinochloa crusgalli (L.) Beauv.), Paspalum bitacica ( Paspalum paspaloides (Michx.) Scribn.), weed leaf age 4-5 leaf stage.

Abstract

The invention relates to a weeding composition containing cyhalofop-butyl, metamifop and propanil. The weeding composition has synergistic effects, and a weight ratio of the cyhalofop-butyl to the metamifop to the propanil is (10-30):(5-15):(15-25), and preferably (20-30):(10-15):(20-25).

Description

technical field [0001] The invention belongs to the field of compounding herbicides, and in particular relates to a herbicidal composition containing cyhalofop-ethyl, fenpyramid and propannil. The herbicidal composition is efficient and thorough in weeding, easy to use, low in cost, and effective on crops. Safety. Background technique [0002] In recent years, the resistance of barnyardgrass in water-seeded rice fields has become stronger and stronger. In the middle and lower reaches of the Yangtze River and Northwest China, a resistant barnyardgrass has appeared in an increasing area. This barnyardgrass has a very strong tillering ability. After that, the common rice field herbicide ingredients such as cyhalofop-methyl, fenpyramid, bispyribac, and quinclorac were basically ineffective. [0003] Cyhalofop-butyl, a highly safe herbicidal active substance for rice, belongs to the class of aryloxyphenoxypropionic acid herbicides, and acts through the systemic conduction of ste...
