Weeding compound containing tembotrions, atrazine and isoxadifen-ethyl

Abstract

The invention relates to a weeding compound containing tembotrions, atrazine and isoxadifen-ethyl. In the weeding compound, the ratio of three components in the weeding compound is (1-10):(1-50):(0.5-10) in parts by weight, the total weight of effective components accounts for 2.5-70 percent of the total weight of the entire weeding compound, the weeding compound is prepared into dosage forms such as a wettable powder, a suspending agent, a dispersible suspending agent, microemulsion in water, emulsion in water, granules and water dispersible granules, and is used for preventing and treating various gramineous weeds, broadleaved weeds and cyperaceous weeds. The weeding compound provided by the invention can improve the durable effect of each component single dosage, obviously delays the production of herbicide resistance, is safe for corn crops, reduces repeated usage amount of pesticides, lowers agricultural utilization cost, can be easily degraded after a period of preserving effect, improves the safety of the compound to next-stubble crops, and reduces pollution to environment.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tembotrione, atrazine and isoxadifen. Background technique [0002] Triketone is a new type of triketone herbicide, which is also an HPPD inhibitor, and is mainly used for weeding in corn fields. Its chemical structural formula is as follows: [0003] [0004] Atrazine, chemical name: 2-chloro-4-diethylamino-6-isopropylamino-1,3,5-triazine, also known as Atrazine. Atrazine is a pre-emergence soil treatment herbicide, and it can also be used for post-emergence stem and leaf treatment. It is mainly absorbed through the roots of the plant and conducted upwards to inhibit weeds (such as cocklebur, foxtail, ragweed, wild cucumber, etc.) ) photosynthesis, causing it to die. Its chemical structural formula is as follows: [0005] [0006] Isoxadifen-ethyl, whose chemical name is 4,5-dihydro-5,5-diphenyl-1,2-azole-3-carboxylic a...

Problems solved by technology

[0009] The purpose of the present invention is to solve the technical problem that existing cornfield herbicides have poor control effects on some grass weeds and broad-leaved weeds. In order to solve this problem, we have designed a three-component compound cornfield herbicide , not only can control a variety of gramineous weeds, broad-leaved weeds, and sedge weeds that can be controlled by tembotrione alone, but also has a very synergistic effect on the control of some gramineous weeds and broad-leaved weeds Significantly, it broadens the herbicidal spectrum, improves the safety of corn, reduces the dosage of pesticides, and saves the cost of control
