Problems solved by technology

[0008] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is easy to produce resistance, the herbicidal spectrum is not wide enough, and it can only control monocotyledonous or dicotyledonous weeds, or can only control emerging weeds. Weeds or unemerged weeds cannot be controlled at the same time

Embodiment 1

[0028] Formulation Example 1: 5.5% Nitrogen·Ethyl·Sodium Metolachlor Granules

[0029] Mesotrione 0.5%,

[0030] Acetochlor 2.5%,

[0031] Sperm metolachlor 2.5%

[0032] Emulsifier 2%,

[0033] Dispersant 3%,

[0034] Methyl Oleate 10%

[0035] Attapulgite particles Supplement.

[0036] The preparation method is as follows: measuring mesotrione, acetochlor, acetochlor, emulsifier, dispersant and methyl oleate respectively, putting them into a sand mill and processing into a sand mill to be processed into mesotrione, acetochlor Amine, metolachlor essence dispersible oil suspension agent, for use. Add the liquid into the attapulgite particle carrier, stir while adding, carry out adsorption, and dry in the air.

Abstract

The invention discloses a ternary weeding compound. The ternary weeding compound contains three active components A, B and C, wherein A is mesotrione, B is acetochlor, C is s-metolachlor, and the massratio of the A to B to C is (0.25-10):(1-30):(1-29). The ternary weeding compound can be prepared into a suspension emulsion, a suspending agent, granules, wettable powder, water dispersible granulesand the like. The ternary weeding compound has an obvious synergistic and weeding effect, the control and removal effect and weeding spectrum are improved, the pesticide use amount is lowered, the ternary weeding compound is particularly suitable for controlling and removing weeds of a cornfield, is worthy of application and popularization and has large economic benefits.

Description

technical field [0001] The present invention relates to an agricultural herbicidal composition. Background technique [0002] Mesotrione, chemical name: 2-(4-methanesulfonyl)-2-nitrobenzoyl)cyclohexane-1,3-dione, CAS number: 104206-82-8. [0003] Mesotrione is a new type of triketone herbicide, which can be used for pre-emergence soil surface treatment or post-emergence spraying on stems and leaves. Safe for subsequent crops. At the same time, its biological activity is more than 10 times more than that of sulcotrione, and it has development potential and competitiveness. Due to its environmental friendliness, it was approved by the US Environmental Protection Agency in 2001 and sold in EU countries and the United States in 2002. However, its control effect on common broad-leaved weeds in corn fields such as cocklebur and bindweed is not very ideal. [0004] Acetochlor, chemical name: 2-ethyl-6methyl--N-ethoxymethyl-α-chloroacetanilide, CAS number: 34256-82-1. [0005] ...
