[0051]

[0052] 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 tembotrione, nicosulfuron, and chlorampridine. Acid water dispersible granules.

Abstract

The invention discloses a pesticide composition containing tembotrions, nicosulfuron and a pyridyloxyacetic acid herbicide. The effective components are the tembotrions, the nicosulfuron and the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid). The weight percentage of the tembotrions in the herbicide is 1%-30%, the weight percentage of the nicosulfuron in the herbicide is 1%-30%, the weight percentage of the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid) in the herbicide is 1%-40%, and the balance is pesticide adjuvants. The pesticide composition has the advantages that the weeding effect is improved after the tembotrions, the nicosulfuron and the pyridyloxyacetic acid (or the ester compound of the pyridyloxyacetic acid) are compounded, a weeding spectrum is widened, the pesticide composition is low in toxicity and low in residue content, the dosage, the application frequency and the using cost are remarkably reduced, the effect of the composition is obviously higher than those of mono-agents, and the pesticide composition is a novel better composition pesticide for preventing and removing annual weed in corn fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a synergistic response herbicidal composition with tembotrione, nicosulfuron, aminopyralid or isooctyl fluroxypyr as active ingredients, and is mainly suitable for controlling Cornfields are especially annual weeds in cornfields with Alternantheraphiloxeroides, Commelina communis and Acalypha australis as dominant weeds. Background technique [0002] Tembotrione is a triketone selective herbicide, which can effectively control the main broad-leaved grasses and some grass weeds, such as velvetleum, amaranth, quinoa, Polygonum, barnyardgrass, crabgrass, etc. Good control effect, can be used for pre-emergence sealing treatment and post-emergence stem and leaf treatment. [0003] Nicosulfuron (nicosulfuron) is a sulfonylurea systemic herbicide and an acetolactate synthase inhibitor, which can be absorbed by the stems, leaves and roots of weeds, and then conduct in plan...
