Embodiment 1

[0047] Embodiment 1: Chitosan oligosaccharide+Verticillium chlamydia nematicide

[0048] It is 2.0 (± 0.5)% by weight in the composition of chitosan oligosaccharide, and 2.5 billion spores / gram Verticillium chlamydia mother powder is 8.0 (± 1.0)% by weight in the composition, and can be formulated Emulsions, microemulsions, emulsions in water, suspensions, water dispersible granules, wettable powders and granules. It is used to control nematodes on various fruit trees such as bananas and citrus, various vegetables such as peppers, tomatoes, cucumbers, and bitter gourds, crops such as tobacco and sugar cane, and forest trees.

[0049] In this example, the low, medium and high contents of each active ingredient are selected to be mixed with each other, and corresponding auxiliaries are added according to the requirements of pesticide processing to make several formulations. Tobacco crops are used as the control object of the embodiment to detect the control effect of the embodi...

Embodiment 2

[0052] Embodiment 2: oligomeric chitosan+emamectin benzoate nematocide

[0053] It is 2.0 (± 0.5)% by weight in the composition of chitosan oligosaccharide, and emamectin benzoate is 1.8 (± 0.5)% by weight in the composition, can be formulated into emulsifiable concentrate, slightly Emulsions, aqueous emulsions, suspensions, water-dispersible granules, wettable powders and granules. It is used to control nematodes on various fruit trees such as bananas, grapes, citrus, various vegetables such as peppers, tomatoes, cucumbers, bitter gourds, ginger, onions, and cereals, beans, potatoes, tobacco, sugarcane, and oil crops.

[0054] In this example, the low, medium and high contents of each active ingredient are selected to be mixed with each other, and corresponding auxiliaries are added according to the requirements of pesticide processing to make several dosage forms. Several crops such as cucumber are used as the control objects of the embodiment to detect the control effect o...

Embodiment 3

[0057] Embodiment 3: chitosan oligosaccharide+thiazophos nematicide

[0058] According to the weight content of oligochitosan in the composition is 2.0 (±0.5)%, and the weight content of thiazolphos in the composition is 8.0 (±1.0)%, it can be formulated into emulsifiable concentrate, microemulsion, water emulsion, suspension, Water-dispersible granules, wettable powders and granules. It is used to control nematodes on various fruit trees such as bananas, grapes, citrus, various vegetables such as peppers, tomatoes, cucumbers, bitter gourds, ginger, onions, and cereals, beans, potatoes, tobacco, sugarcane, and oil crops.

[0059] In this example, the low, medium and high contents of each active ingredient are selected to be mixed with each other, and corresponding auxiliaries are added according to the requirements of pesticide processing to make several dosage forms. These several crops of pine trees are used as the control objects of the embodiment to detect the control eff...

Abstract

The invention relates to the technical field of a pesticide composition for preventing and controlling nematode. The pesticide composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is chitooligosaccharide; the active ingredient B is any one or a combination of any two or three of verticillium chlamydosporium, emamectin benzoate and lythidathion. The formula of the pesticide composition has the advantages of synergistic interaction, reasonable proportion and particularly good prevention and control effect on crop nematode and economic forest nematode.

Description

technical field [0001] The invention belongs to the field of pesticides and relates to a pesticide composition for nematode control. Background technique [0002] Chitosan oligosaccharide, chemical name is β-1,4-oligo-glucosamine, molecular formula: (C 6 h 11 o 4 N)n (n≥2) is an oligomer with a degree of polymerization of 2-15 produced by enzymatic hydrolysis of polysaccharide biological natural products extracted from biological chitin. Chitosan oligosaccharide has a good control effect on diseases caused by various fungi, bacteria and viruses. [0003] Verticillium chlamydosporium sp. is a facultative endoparasitic fungus that can live saprophytically in the soil and parasitize Globoderaspp. and cyst nematodes in the root zone of plants (Heteroderaspp.) and root-knot nematodes (Meloidogynespp.) and other plant nematodes with strong fixation, cysts, oocysts or eggs. It is an important natural enemy of some parasitic nematodes. Widely used in the prevention and control...
