Embodiment 1

[0030] The emulsifiable concentrate of the nematicide composition of the present invention contains the following components in weight percent: 1-40% of fluthiazol, 1-40% of carbosulfan, 3-10% of emulsifier, and 2-8% of dispersant , 5-20% solvent, 5-20% co-solvent. After mixing and stirring the original drug, solvent and cosolvent evenly, adding emulsifier and dispersant and stirring evenly, it can be prepared.

Embodiment 2

[0032] The suspending agent of the nematicide composition of the present invention contains the following components in weight percent: 1-40% of fluthiazol, 1-40% of carbosulfan, 2-8% of wetting agent, and 2-8% of dispersing agent %, antifreeze 7-12%, thickener 0.1-0.5%, defoamer 0.1-0.8%, preservative 0.1-0.8%, water balance. First mix the original drug, wetting agent, dispersant, antifreeze and preservative, mix evenly by high shear, then sand mill for 1.0~1.5h, add defoamer, thickener and water at low speed, and you are done. be made of.

Embodiment 3

[0034] The nematicide composition is a water-dispersible granule, which contains the following components in weight percent: fluthiazol 1-40%, carbosulfan 1-40%, wetting agent 1-5%, dispersant 1 ~5%, disintegrant 2~8%, filler balance. Mix all raw materials evenly, pass through a jet mill, knead and granulate, dry and sieve to obtain the product.

Abstract

The invention relates to the field of insecticides, and specifically discloses a nematocidal composition containing fluthiazol and carbosulfan. The nematicide composition of the present invention comprises: 1-40% fluthiazol, 1-40% carbofuran, and the balance of adjuvants by weight, which can be compounded into emulsifiable concentrates, suspending agents, Water-dispersible granules, wettable powders, emulsions in water, granules, etc., have high-efficiency, broad-spectrum, low-toxicity, and environmental-friendly insecticidal effects.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a nematocidal composition containing fluthiazol and carbosulfan. Background technique [0002] Fluensulfone is the only new chemical nematicide developed in the past 20 years. It is a fluoroolefin sulfide compound. It acts on nematodes through contact killing. Stop feeding after 1 hour, the ability to infect and lay eggs will decrease, the hatching rate of eggs will decrease, and the hatched larvae will not survive, and its irreversible nematicidal effect can cause nematodes to die. Because fluthiazol has significant control effects on various plant parasitic nematodes, including the seriously harmful root-knot nematode, and has the advantages of low toxicity, low environmental risk and simple use, it has a good development prospect in the control of nematodes. However, in specific applications, there are many problems with a single bactericidal component, such as: large dosage, rapi...
