Herbicide composition as well as preparation method and application thereof

Abstract

The invention discloses a herbicide composition as well as a preparation method and application thereof. The herbicide composition is a three-component herbicide composition comprising nicosulfuron, atrazine and fiuroxypyr used as active components, wherein the proportion by weight of the nicosulfuron to the atrazine to the fiuroxypyr is 1-10:5-50:1-20. The preparation method of the composition comprises the following steps of: firstly weighing primary medicines and auxiliary agents, then adding the nicosulfuron as the primary medicine, the atrazine as the primary medicine, the fiuroxypyr as the primary medicine, the auxiliary agents and a solvent into a ball mill for milling for 2-3 hours, transferring into a sand mill for sanding for 3-4 hours, adding into a finished-product blending tank, sampling, analyzing and blending. The composition is suitable for preventing and removing in-field weeds and is particularly suitable for preventing and removing the weeds in corn fields. The herbicide composition can play the weeding effect within a short period of time and has good weeding effect, thereby the dosage of a herbicide is reduced.

Description

technical field [0001] The invention relates to a herbicidal composition for controlling weeds in farmland, in particular to a herbicidal composition for controlling grass weeds and broadleaf weeds in corn fields, and a preparation method and application thereof. Background technique [0002] Chemical weeding is the development trend of modern agriculture, and chemical herbicides have been widely used in corn in northern my country, which has produced great economic benefits. Among them, the compound nicosulfuron is a new type of herbicide, which can be used for the control of monocotyledonous and dicotyledonous weeds in corn fields. However, due to the low content of this agent (below 4.1%), the efficacy is not ideal, and the existing compound nicosulfuron is combined with other agents, so it cannot be used for older weeds, with a long effective time and a large amount of use. , high cost, poor effect, especially in arid climatic conditions, the efficacy is significantly r...

AI Technical Summary

Problems solved by technology

Among them, the compound nicosulfuron is a new type of herbicide, which can be used to control monocotyledonous and dicotyledonous weeds in corn fields. It can kill both grass and broadleaf. It has a good effect on corn after seedlings, and is highly safe for corn. However, due to the low content (below 4.1%) of this medicament at present, the drug effect is not ideal, and the existing compound nicosulfuron cooperates with other medicaments, so it cannot be used for older weeds, and the effective time is long and the amount of use is large. , high cost, and poor effect, especially in arid climate conditions, the efficacy of the drug is significantly reduced, which directly affects its application performance
