Weedicide composition containing Tembotrione, Terbuthylazine and Isoxadifen-ethyl

Abstract

The invention relates to a weedicide composition containing Tembotrione, Terbuthylazine and Isoxadifen-ethyl. The weight part ratio of the three active components in the preparation is (1-10):(1-50):(0.5-10), and the total weight part of the active components accounts for 2.5-70% of the total weight part of the whole preparation. The weedicide composition can be prepared into multiple agricultural chemical preparation forms such as wettable powder, suspending agents, dispersible suspending agents, microemulsion, emulsion in water, granules and water-dispersible granules, and is used for controlling multiple grassy weeds, broadleaf weeds and sedge weeds. The weedicide composition can control the multiple grassy weeds, broadleaf weeds and sedge weeds capable of being controlled by single use of the Tembotrione, improves the control effect on part of the grassy weeds and broadleaf weeds, widens the weed control spectrum, additionally has a particular sealing effect of the Terbuthylazine, improves the degree of safety for corns, lowers the dosage, saves the control cost, improves the safety for succeeding crops, and reduces pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tembotrione, terbuthazine and isoxadifen. Background technique [0002] Tembotrione, a new type of triketone herbicide, is also an HPPD inhibitor, mainly used for weeding in corn fields. Its chemical structural formula is as follows: [0003] [0004] Terbutylazine (Terbutylazine), chemical name: N2-tert-butyl-6-chloro-N4-ethyl-1.3.5-triazine-2,4-diamine. It belongs to the 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 plants and conducted upwards, inhibiting the photosynthesis of most weeds and causing them to die. Its chemical structural formula is as follows: [0005] [0006] Isoxadifen-ethyl, the chemical name is 4,5-dihydro-5,5-diphenyl-1,2-azole-3-carboxylic acid ethyl ester, which belongs to the isoxazole sa...

Problems solved by technology

[0011] 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
