Problems solved by technology

In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance; at the same time, due to the complex grass phase and various types of weeds in the field, such as grass weeds, sedge weeds Mixed with broad-leaved weeds, etc., the single or dual compound use of herbicides can no longer effectively solve the above problems, and all of them will show some defects

Embodiment 1

[0034] Example 1: 30% Benthiazamide Mesotrione Mesotrione Ethsulfuron-methyl Dispersible Oil Suspension Concentrate

[0035] Mefenacet 25%, Mesotrione 4%, Ethsulfuron 1%, Sodium Lauryl Sulfate 8%, EO-PO Block Copolymer 7%, Sodium Alkylphenol Polyoxyethylene Ether Sulfate 5%, carboxymethyl cellulose 2%, sodium chloride 2%, palm oil to make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 30% mefenacet-mesotrione-ethoxysulfuron-methyl dispersible oil suspension concentrate.

Embodiment 2

[0036] Example 2: 17% Mesotrione Mesotrione Mesotrione Trisulfuron-methyl Dispersible Oil Suspension Concentrate

[0037]Mefenacet 15%, Mesotrione 1%, Flurimsulfuron 1%, Pull Open Powder BX 10%, EO-PO Block Copolymer 8%, Castor Oil Polyoxyethylene Ether 7%, Carboxymethyl Base cellulose 2%, sodium chloride 2%, rapeseed oil make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 17% fenthiazide·mesotrione·pyrimsulfuron-methyl dispersible oil suspension concentrate.

Embodiment 3

[0038] Example 3: 19% Benthiazamide Mesotrione Mesotrione Promethazone-methyl Dispersible Oil Suspension Concentrate

[0039] Mefenacet 15%, Mesotrione 1%, Promasulfuron-methyl 3%, Pull Opening Powder BX 10%, Lignosulfonate 10%, Castor Oil Polyoxyethylene Ether 8%, Xanthan Gum 2.5%, sodium chloride 2%, and linseed oil make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 19% mefenacet-mesotrione-promethazone-methyl dispersible oil suspension concentrate.

Abstract

The invention discloses a herbicidal composition for paddy fields. The active ingredients of the herbicide composition consist of mefenacet, mesotrione and a sulfonylurea herbicide, wherein the sulfonylurea herbicide is selected from ethoxysulfuron, orthosulfamuron, propyrisulfuron and metazosulfuron, and the weight ratio of the mefenacet to the mesotrione to the sulfonylurea herbicide is (1-500):(1-100):(1-100). The herbicidal composition of the present invention is mainly applied to prevention and elimination of weeds in paddy fields, the weeding effect is obviously improved compared with that of an independently used single reagent or a reagent formed by mutual binary compounding, and the weeding spectrum is expanded, the persistent effect is long, and the herbicidal composition is safeto rice. The herbicidal composition formed through ternary compounding of the mefenacet, the mesotrione and the sulfonylurea herbicide has substantial synergic effect, can reduce the effective usageamount of the single reagents, is reduced in usage cost, alleviates environmental pollution, delays drug resistance of weeds and is increased in service life.

Description

technical field [0001] The present invention relates to the field of pesticide composition and its application, specifically a kind of herbicidal composition with mesotrione, mesotrione and sulfonylurea herbicides as effective active ingredients. Control of weeds in paddy fields. Background technique [0002] Mefenacet, an anilide herbicide, is an inhibitor of cell growth and division, eventually causing plant death. It can be used to control annual weeds such as barnyardgrass, sedge, and shaped sedge in paddy fields. [0003] Mesotrione is a p-hydroxyphenyl ketone dioxygenase inhibitor, which can be absorbed by the roots, stems and leaves of plants. The accumulation of plastoquinone and tocopherol hinders the biosynthesis of carotenoids, leading to the death of weed stems and leaves after bleaching. It is mainly used for controlling annual weeds after corn and sugarcane seedlings. [0004] Ethoxysulfuron (ethoxysulfuron) is a sulfonylurea herbicide, which can control du...
