Embodiment 1

[0044] 5% Thiazophosphine Chitosan Granules:

[0045] Thiazophosphine 4%, chitosan 1%, alkylphenol polyoxyethylene ether 3%, polyoxyethanol 5%, sodium dodecyl sulfonate 5%, sodium butylnaphthalene sulfonate 2%, kaolin supplemented to 100%. The above materials are mixed and kneaded by adding water, kneaded and shaped by a kneading granulator, and then dried and sieved by a fluidized bed to obtain 5% thiazophosphine-chitosan granules.

Embodiment 2

[0047] 5% Thiazophosphine Matrine Granules:

[0048]Thiazophosphine 3%, matrine 2%, alkylphenol polyoxyethylene ether 3%, polyoxyethanol 5%, sodium dodecylsulfonate 5%, sodium butylnaphthalenesulfonate 3%, kaolin supplemented to 100 %. The above materials are kneaded by mixing and adding water, kneaded and shaped by a kneading granulator, and then dried and sieved by a fluidized bed to obtain 5% thiazophosphine-matrine granules.

Embodiment 3

[0050] 8% Thiazophosphine Chitosan Granules:

[0051] Thiazophosphine 6%, chitosan 2%, alkylphenol polyoxyethylene ether 5%, polyoxyethanol 6%, sodium dodecylsulfonate 5%, sodium butylnaphthalenesulfonate 4%, kaolin supplemented to 100%. The above materials are mixed and kneaded by adding water, kneaded and shaped by a kneading granulator, and then dried and sieved by a fluidized bed to obtain 8% thiazophosphine-chitosan granules.

Abstract

The invention relates to a nematicidal composition containing fosthiazate. The composition comprises an effective component A and an effective component B, wherein the effective component A is fosthiazate, the effective component B is chitosan or matrine, and the weight ratio of the component A to the component B is (50-1):(1-50). The composition can be applied to pesticide manufacturing and prepared into various preparations allowed in agriculture. The composition is reasonable in component compounding and good in plant nematode prevention effect, the nematicidal effect of the composition is not simple combination of activity of the components, and compared with a single preparation, the composition is obvious in synergistic effect and more excellent in nematicidal effect. In actual application, pesticide residues are reduced, the pesticide consumption is low, the service life of pesticides is prolonged, and drug resistance of pests is delayed. Chitosan and matrine serve as biological pesticide and is environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a nematocidal composition containing thiazophosphine. Background technique [0002] Nematodes belong to the nematode class Nematodes. They are small in size and can only be observed with a microscope. It is common in China and the damage is serious. Most of the nematodes that are harmful to plants live in the soil, and some also parasitize in plants. Nematodes spread through soil or seeds, which can damage the root system of plants; nematodes feed directly on plants, which can greatly reduce the absorption of nutrients and water by plants; nematodes feed on plants and cause wounds, which also provide convenience for plant pathogens to invade , bacteria, and viruses interact to form a compound infection, which indirectly spreads fungal and bacterial diseases caused by other microorganisms, aggravating the damage to crops and causing huge economic losses.
