Embodiment Construction

[0091] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is illustrated with the following specific examples, but the present invention is by no means limited to the examples. The present invention adopts the method of combining indoor bioassay and field test. Unless otherwise specified, the ratios (including percentages) mentioned below are ratios in parts by weight.

[0092] The optimum weight ratio of the active ingredients of A, B and C is 1:(20-50):1.

[0093] Specific examples of wettable powder in the present invention: mix 2 parts of tembotrione, 30 parts of terbuthyridine, 2 parts of potassium salt of isoxadifen, 8 parts of dispersant, 10 parts of wetting agent and 48 parts of filler, mix in Stir evenly in a stirring tank, and then mix evenly after passing through a jet mill to obtain the wettable powder of the herbicidal composition of the present invention.

[0094] As shown in Table 1, the w...

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...
