Embodiment 1

[0032] Example 1 90% dicamba sodium salt · atrazine water dispersible granules

[0033] Wheat straw sodium salt 34%, atrazine 56%, dispersant polycarboxylate sodium salt 1.5%, alkylphenol sulfonate sodium 1%, lignosulfonate calcium 1.5%, wetting agent a-sulfo fatty acid methyl ester 0.1 %, α-olefin sulfonate sodium 1.0%, fatty amide N-methyl taurine sodium salt 0.4%, disintegrant potassium dihydrogen phosphate 1.0%, diammonium hydrogen phosphate 0.32%, potassium chloride 0.18%, kaolin supplement 100%, after the mixture is fully mixed evenly, carry out ultra-fine airflow pulverization to obtain 700 mesh fine powder, then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and fluidize in boiling Dry in bed at 65°C to obtain 90% dicamba salt · atrazine water dispersible granules.

Embodiment 2

[0034] Example 2 70.49% dicamba sodium salt · atrazine water dispersible granules

[0035] Dicamba sodium salt 26.6%, atrazine 43.89%, dispersant polycarboxylate sodium salt 1.5%, alkylphenol sulfonate sodium 1%, lignosulfonate calcium 1.5%, wetting agent a-sulfo fatty acid methyl ester 0.1%, sodium a-olefin sulfonate 1.0%, fatty amide N-methyl taurine sodium salt 0.4%, disintegrant potassium dihydrogen phosphate 1.0%, diammonium hydrogen phosphate 0.32%, potassium chloride 0.18%, kaolin Make up 100%, after the mixture is fully mixed evenly, carry out ultra-fine airflow pulverization to obtain 700 mesh fine powder, then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and grind in a boiling flow Dry at 65°C in a chemical bed to obtain 70.49% dicamba salt · atrazine water dispersible granules.

Embodiment 3

[0036] Example 3 10.6% dicamba sodium salt · atrazine water dispersible granules

[0037] Dicamba sodium salt 4%, atrazine 6.6%, dispersant polycarboxylate sodium salt 1.5%, alkylphenol sulfonate sodium 1%, calcium lignosulfonate 1.5%, wetting agent a-sulfo fatty acid methyl ester 0.1%, sodium a-olefin sulfonate 1.0%, fatty amide N-methyl taurine sodium salt 0.4%, disintegrant potassium dihydrogen phosphate 1.0%, diammonium hydrogen phosphate 0.32%, potassium chloride 0.18%, kaolin Make up 100%, after the mixture is fully mixed evenly, carry out ultra-fine airflow pulverization to obtain 700 mesh fine powder, then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and grind in a boiling flow Dry at 65°C in a chemical bed to obtain 10.6% dicamba salt · atrazine water dispersible granules.

Abstract

The invention relates to water dispersible granules containing dicamba salt and atrazine and a method for manufacturing the water dispersible granules. The preparations containing the dicamba salt and the atrazine which are used as active ingredients have a remarkable synergistic interaction effect, most monocotyledon and dicotyledonous weeds in corn fields can be controlled and eliminated at one step, the weeds are controlled in an entire growth period of corns, the water dispersible granules are safe for the corns and after-culture crops, a weeding spectrum is enlarged, insecticide resistance of main weeds and resurgence of secondary weeds are deferred, the service lives of the insecticides are prolonged, environmental pollution is alleviated, and the water dispersible granules have important economic, environmental protection and ecological significances.

Description

technical field [0001] The invention relates to a pesticide herbicide preparation and a preparation method thereof, in particular to a water-dispersible granule containing dicamba salt and atrazine and a preparation method thereof. Background technique [0002] Both dicamba and atrazine can be used to control weeds in corn fields, but with the increase of the application period, the weeds' resistance to a single agent increases year by year, and it is necessary to increase the dosage and frequency of application to achieve the weeding effect. The cost is increased, the environmental pressure is also increased, and the phytotoxicity of the sensitive crops after the crop is also increased. The above problems are solved by compounding dicamba salt and atrazine in a certain proportion, which is of great significance for practical application. [0003] Patent CN1194612C discloses a mixed herbicide preparation of dicamba and atrazine. This patent discloses the technology of compo...
