Embodiment 1

[0080] Example 1: Mix 20 parts of tembotrione, 0.5 parts of isoxadifen, 8 parts of dispersant, 10 parts of wetting agent and 62 parts of filler, stir evenly in a stirring tank, and mix evenly after passing through a jet mill , that is, to prepare the wettable powder of the herbicidal composition of the present invention.

Embodiment 2

[0081] Example 2: Mix 10 parts of tembotrione, 5 parts of potassium salt of isoxadifen, 7 parts of dispersant, 10 parts of wetting agent and 68 parts of filler, stir evenly in a stirring tank, pass through a jet mill Mix evenly to obtain the wettable powder of the herbicidal composition of the present invention.

Embodiment 3

[0082] Example 3: Mix 25 parts of tembotrione, 1 part of potassium salt of isoxadifen, 1.5 parts of sodium salt of isoxadifen, 12 parts of dispersant, 15 parts of wetting agent and 45 parts of filler, and mix in a stirred tank Stir uniformly in the medium, and mix evenly after passing through the airflow mill, and then the wettable powder of the herbicidal composition of the present invention is obtained.

Abstract

The invention relates to a weeding composition containing tembotrione and isoxadifen-ethyl. The weeding composition preparation comprises tembotrione and isoxadifen-ethyl or a salt of isoxadifen-ethyl, wherein the weight part ratio of the two effective components in the preparation is 55:1 to 0.1:30, and the total weight parts of the effective components in the weeding composition preparation accounts for 1%-60% of the total weight parts of the whole preparation. The weeding composition preparation can be made into pesticide preparation dosage forms such as a wettable powder, a suspending agent, an emulsifiable concentrate, a micro-emulsion, an emulsion in water, granules and water dispersible granules. The weeding composition has a remarkable synergistic effect, improves the persistence of single agents, significantly delays the generation of weed drug resistance, reduces the number of times of pesticide repeated use, lowers the using amount of pesticides, and lowers agricultural costs; and the weeding composition is safe to agricultural crops, is easy to degrade in the environment after an effect preserving period, improves the safety of the composition on next-stubble crops, and has Important significance on protection of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing tembotrione 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: [0003] . [0004] Isoxadifen, chemical name is 4,5-dihydro-5,5-diphenyl-1,2-oxazole-3-carboxylic acid, belongs to isoxazole safener, mainly used in Prevention and control of annual and perennial weeds in corn fields. [0005] Due to the wide variety of herbicides currently used in agricultural production, the drug toxicity is high, and the residual amount is high, it is easier to make weeds resistant. When a herbicide with a single active ingredient is used, its weeding effect will be greatly reduced due to factors such as resistance. . If we continue to create new herbicide technical compounds, the crea...
