preparation example Construction

[0033] The preparation method of the suspension is as follows: the above-mentioned dispersant, wetting agent, defoamer, binder, antifreeze and deionized water are mixed evenly through high-speed shearing, then chlorpyrifos and Tioxazafen are added, and 2-3 Hours, to make the particle size below 5 μm.

[0034] The composition of the present invention can also be made into granules composed of chlorpyrifos, Tioxazafen, dispersant, binder and filler. The mass percentage of each component in the granule is 1-20% of chlorpyrifos, 1-20% of Tioxazafen, 3-15% of dispersant, 1-10% of binder, and 100% of filler .

[0035]The dispersant is alkyl naphthalene sulfonate, bis(alkyl) naphthalene sulfonate formaldehyde condensate, naphthalene sulfonate formaldehyde condensate, arylphenol polyoxyethylene succinate sulfonate, octylphenol polymer Oxyvinyl ether sulfate, polycarboxylate, lignosulfonate, alkylphenol polyoxyethylene pyrimaldehyde condensate sulfate, alkylbenzenesulfonate calcium s...

Abstract

The invention discloses a chlorpyrifos and Tioxazafen-containing nematicidal composition and belongs to composite pesticides. The chlorpyrifos and Tioxazafen-containing nematicidal composition is used for preventing and controlling root nematodes of crops and is prepared from chlorpyrifos and Tioxazafen with the weight ratio being (20 to 1)-(1 to 20). A dosage form of the chlorpyrifos and Tioxazafen-containing nematicidal composition is a suspension concentrate or granules. The chlorpyrifos and Tioxazafen-containing nematicidal composition is reasonable in components, small in application amount, low in preventing and controlling cost and remarkable in synergistic action, can delay generation of resistance to drugs and is high in safety to crops and operators.

Description

technical field [0001] The invention relates to a pesticide composition, especially a pesticide composition containing chlorpyrifos and Tioxazafen, which belongs to compound pesticide and is used for preventing and controlling root nematodes of crops. Background technique [0002] Nematodes belong to the nematode class Nematodes. They are so small that they cannot be seen with the naked eye, but can only be observed with the help of a microscope. There are about 3,000 kinds of nematodes harmful to plants, most of which live in the soil, and some also parasitize in plants. Nematodes are a kind of extremely harmful insect pests. They have the characteristics of wide distribution, various types, strong environmental adaptability, fast reproduction speed, and increasing drug resistance. Therefore, it is very difficult to control them. The aerial parts of the damaged plants show short growth, slow growth, abnormal leaf color, few fruits, low yield, and even cause early death of ...
