Embodiment 3

[0065] Example 3: Flupyrazone·octanoylbromoxynil·aminopyralid water dispersible granules.

[0066]

[0067] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain the corresponding weight percentage of Flupidalone·octanoylbromoxynil·chlorine Fampridine water dispersible granules.

Abstract

The present invention relates to a pesticide composition of flumefenidone, bromoxynil octanoyl and pyridine carboxylic acid herbicides, the active ingredients are flumefenidone, bromoxynil octanoyl, and pyridine carboxylic acid herbicides; The acid herbicide is selected from one of aminopyralid and isooctyl fluroxypyr; the weight percentage of fluroxypyrone in the composition is 1% to 30%, and bromoxynil in the composition The weight percentage in the composition is 1% to 30%, the weight percentage of the pyridine carboxylic acid herbicide in the composition is 1% to 30%, and the rest are pesticide adjuvants. The composition of the invention is reasonable, has a synergistic response to weeds in corn fields, expands the herbicidal spectrum of a single agent, and reduces the risk of weed resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition with flumetrazone, bromoxynil octanoyl and pyridine carboxylic acid herbicides as active ingredients, which is suitable for controlling annual weeds in corn fields, especially barnyardgrass Grass (Echinochloa crusgalli), purslane (Portulacaoleracea), and lacquer (Euphorbia helioscopia) are dominant weeds in cornfields. Background technique [0002] Bicyclopyrone, a triketone ketone herbicide, is absorbed through plant roots and leaves, and conducts in the body to inhibit hydroxyphenylpyruvate dioxygenase, resulting in the accumulation of tyrosine, plastoquinone and The biosynthesis of tocopherol stops, which in turn leads to a decrease in chlorophyll content, causing the plant meristems to lose chlorosis and cause albino death. It can prevent and control annual weeds. It can be used for pre-emergence soil surface treatment and post-emergence...
