Pesticide composition containing albendazole and fluensulfone

Abstract

The invention discloses pesticide composition containing albendazole and fluensulfone. The pesticide composition comprises a first effective ingredient albendazole, a second effective ingredient fluensulfone and common auxiliary ingredients, wherein the weight ratio of the albendazole to the fluensulfone is (40:1)-(1:40), and the albendazole and the fluensulfone accounts for 0.1%-80% of the total weight of the composition. A large number of indoor and outdoor tests indicate that the pesticide composition has the significant synergistic effect, the control effect on crop nematodes is obviously superior to that of each single agent used separately, the fast-acting property is good, and the lasting period is long. Meanwhile, the usage amount of pesticide is decreased, the residual amount of the pesticide on plants is decreased, environmental pollution is reduced, production of drug resistance of the nematodes is delayed, and the service life of the pesticide is prolonged.

Description

technical field

[0001] The invention relates to the field of pesticide composition and its application, in particular to a pesticide composition with prothiazole and sulfone as active ingredients, which is used for preventing and controlling crop nematodes. Background technique

[0002] Albendazole is a benzimidazole insecticide. As a medicine, it can be used to drive roundworms, pinworms, tapeworms, whipworms, hookworms, strongyloides, etc. After being metabolized into sulfoxides or sulfones in the body, it can inhibit the absorption of glucose by parasites, resulting in the depletion of glycogen in the parasites, or inhibit the fumarate reductase system, hinder the production of ATP, and make the parasites unable to survive and reproduce. Crop pesticides have significant control effects on a variety of plant diseases, and have a certain effect on increasing production. At the same time, they also have a good control effect on nematodes on plants.

Examples

Embodiment 1

[0016] Example 1: 22% prothiazol·fluoromethazolone microcapsule suspension.

[0017] The following substances are all percentages by weight: 2% prothioazole, 20% sulfone sulfone, 10% tolyl isocyanate, 10% trimethylbenzene, 10% ethyl acetate, 5% castor oil polyoxyethylene ether, lignosulfonic acid Calcium 3%, sodium hydroxide 2%, deionized water make up to 100%. Mix the above effective ingredients, polymer capsule wall materials, and solvents to dissolve them into a uniform oil phase. Under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifiers, dispersants, and pH regulators. Make up with deionized water, and the two materials react at the oil-water interface to form a polymer capsule wall, and then the 22% prothiozol·fluoxene sulfone microcapsule suspension can be prepared.
