Problems solved by technology

At present, there is no report on the technology of using dimethyltetrachloride and propanil as active ingredients to control weeds in rice fields. The compounded product of dimethyltetrachloride and propanil can obviously save economic costs, and can also It is of great economic, environmental and ecological significance to reduce pesticide residues in agricultural products and the environment, delay the emergence of primary weed resistance and secondary weeds, and prolong the service life of pesticides.

Embodiment 1

[0048] Example 1 67.5% dimethyltetrachloride sodium propanil water dispersible granules

[0049] Dimethyl tetrachloride sodium salt 60%, propanil 7.5%, dispersant polycarboxylate sodium salt 3.75%, calcium lignosulfonate 1.25%, wetting agent a-sulfo fatty acid methyl ester 0.5%, a-olefin sulfonic acid Sodium 0.5%, fatty amide N-methyl taurine sodium salt 1.0%, disintegrating agent urea 1.5%, sodium sulfate 1.5%, kaolin supplement 100%, after the mixture is fully mixed, carry out ultra-fine jet milling to obtain 750 mesh Fine powder, then knead the resulting fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and dry at 50°C in a fluidized fluidized bed to obtain 67.5% dimethyltetrachloride. Propanil water dispersible granules.

Embodiment 2

[0050] Example 2 67.5% dimethyl tetrachloride sodium salt propanil water dispersible granules

[0051] Dimethyl tetrachloride sodium salt 60%, propanil 7.5%, dispersant maleic acid-acrylic acid copolymer salt 3.0%, wetting agent wetting agent sodium lauryl sulfate 5.0%, disintegrant potassium chloride 10% , sodium sulfate 1.5%, and attapulgite to make up 100%. After the mixture is fully mixed and uniform, it is pulverized by ultra-fine airflow to obtain a 750-mesh fine powder. Granulate in a granulator and dry in a fluidized bed at 50°C to obtain 67.5% dimethyltetrachloride · propanil water dispersible granules.

Embodiment 3

[0052] Example 3 67.5% dimethyltetrachloride sodium propanil water dispersible granules

[0053] Dimethyl tetrachloride sodium salt 33.75%, propanil 33.75%, dispersant polycarboxylate sodium salt 3.75%, calcium lignosulfonate 1.25%, wetting agent a-sulfo fatty acid methyl ester 0.5%, a-olefin sulfonic acid Sodium 0.5%, fatty amide N-methyl taurine sodium salt 1.0%, disintegrating agent urea 1.5%, sodium sulfate 1.5%, kaolin supplement 100%, after the mixture is fully mixed, carry out ultra-fine jet milling to obtain 750 mesh Fine powder, then knead the resulting fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and dry at 50°C in a fluidized fluidized bed to obtain 67.5% dimethyltetrachloride.

Abstract

The invention discloses a phytocidal composite containing methoxone salt and propanil. The composite uses the methoxone salt and the propanil as active ingredients, and the mass ratio of the methoxone salt and the propanil is 1-80 to 1-80. The invention also discloses applications of the phytocidal composite. The methoxone salt and the propanil are mixed, so that the phytocidal composite has a significant synergistic effect, the advantages of the methoxone salt and the propanil are effectively exerted, and the obtained product has a good quality and a good effect, is suitable for crops such as rice to effectively prevent and kill weeds such as barnyard grass, semen euphorbiae, crab grass, green bristlegrass, kochia scoparia, amaranthus retroflexus, dayflower and the like. The preparation method of the phytocidal composite is simple, the operation is convenient, and the energy consumption is low. The mixed composite reduces the usage amount of drugs, the resistance to drugs of main weeds to a single drug and the resurgence of the main weeds are delayed, and the phytocidal composite has good social, economic and ecological significances.

Description

technical field [0001] The invention relates to a compound herbicidal composition and its application, in particular to a herbicidal composition containing dimethyltetrachloride and propannil and its application, and belongs to the technical field of pesticides. Background technique [0002] 2-methyl-4-chloro, English name: MCPA, chemical name: 2-methyl-4-chlorophenoxyacetic acid. The pure product of 2M and 4Cl is colorless and odorless crystal, which can form corresponding salts with various alkalis, generally made into sodium salt, and easily soluble in water. Dimethyltetrachloride is a phenoxyacetic acid selective systemic conduction hormone herbicide, which can destroy the conduction tissue of dicotyledonous plants, disturb the growth and development, twist the stems and leaves, and swell and thicken the base of the stems or crack. It is mainly used to control willow-leaved Polygonum, sorrel leaf, Chenopodium, retroverted amaranthus, cocklebur, quince, convolvulus, lett...
