Novel compound weeding preparation for cotton fields and preparation method thereof

Abstract

The invention discloses a novel compound weeding preparation for cotton fields, which comprises the following components in percentage by weight: 15-25% of prometryn, 15-25% of fluometuron, 5-10% of glyphosate isopropylamine salt, 3-5% of dispersing agent, 3-5% of synergist, 2-8% of stabilizer, 3-6% of thickener and the balance of water. The invention also discloses a preparation method of the novel compound weeding preparation for cotton fields. The novel compound weeding preparation for cotton fields is used for cotton fields, and has an obvious synergistic action and lower consumption as compared with a common single weedicide; the novel compound weeding preparation for cotton fields can prevent and remove elder worst weed, has the characteristics of wide weed control spectrum and long duration time, and can ensure no weed for the whole season after being applied once; and the preparation uses water as the carrier, and thus, is safe and environment-friendly. The novel compound weeding preparation for cotton fields has the advantages of low cost, simple production procedure, high safety and broad weed control spectrum, and especially has favorable preventive effects on elder worst weed.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, relates to a new compound herbicide preparation for cotton fields, and also relates to a preparation method of the new compound herbicide preparation for cotton fields. Background technique [0002] my country is one of the largest cotton-producing countries in the world. There are more than 60 species of weeds in 24 families in cotton fields. The loss of cotton due to grass damage is 14.8%, and the production of lint is reduced by about 255,000 tons. These weeds are also hosts for cotton pests and diseases. It is imminent to develop a safe, broad-spectrum, long-lasting and high-efficiency herbicide. [0003] Flumeuron is one of the main herbicides used in cotton fields. It has a good control effect on most weeds, but it has poor effect on grass weeds such as crabgrass, the main weed, and has a long residual effect period. It is necessary to add other ingredients to improve its h...
