Abstract
The invention discloses a suspending agent assistant of glufosinate-ammonium compounded quizalofop-p-ethyl and oxyfluorfen, which comprises the following components in percentage by mass: 1-40% of styryl phenol polyoxyethylene ether phosphate, 1-45% of polycarboxylate dispersant, 1-20% of lauramidopropyl amine oxide, 1-20% of diisooctyl succinate sodium sulfonate and water. The assistant of the invention ensures that the pesticide composition has stable dispersion and suspension performance, has obvious synergistic effect, obviously delays the generation of weed resistance, reduces the times of repeated use of the pesticide and reduces the agricultural cost.
Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a high-efficiency auxiliary agent of a suspending agent of glufosinate-ammonium compounded quizalofop-p-ethyl and oxyfluorfen.
Background
Glufosinate belongs to phosphonic acid herbicides and can inhibit glutamine synthetase in plant nitrogen metabolic pathways, so that metabolism of plants is interfered, and the plants die. Glufosinate is an excellent non-selective and broad-spectrum contact herbicide, and with the rising of glyphosate resistance and the limited use of paraquat, the glufosinate sales are rising continuously, and the glufosinate becomes a herbicide for the second major transgenic crop in the world.
Oxyfluorfen belongs to fluorine-containing diphenyl ether, is a selective, pre-bud and post-bud contact-type herbicide with ultralow dosage, and weeds are killed mainly by absorbing medicaments through coleoptiles and mesocotyl. The herbicide composition is suitable for rice, soybean, wheat, cotton, corn, oil palm, vegetables, orchards and the like, and is used for preventing and killing broadleaf weeds and certain gramineous weeds, such as dayflower, barnyard grass, nutgrass flatsedge, sesbania, brome, stramonium and the like.
The quizalofop-p-ethyl is absorbed by the stem leaves of the weeds, is conducted in the plant body in two directions upwards and downwards, is accumulated on the top and the intermediate meristem, inhibits the synthesis of cell fatty acid and leads the weeds to be necrotic. Quizalofop-p-ethyl is a novel high-selectivity stem and leaf treating agent for dry farmland, has high selectivity between gramineous weeds and dicotyledonous crops, and has good control effect on gramineous weeds in broad leaf crop fields. Quizalofop-p-ethyl has fast acting speed and more stable drug effect, and is not easily influenced by environmental conditions such as temperature, humidity and the like of rainwater.
Resistant weeds continue to increase as the population of herbicide resistant weeds evolves as a result of the inevitable long-term application of a single mode of action herbicide. In order to slow down the development of glufosinate-ammonium resistant weeds, improve the weeding speed of glufosinate-ammonium and expand the weeding spectrum, the combination of glufosinate-ammonium and other herbicides becomes a future development trend.
