Embodiment 1

[0033] The present embodiment provides a kind of nematicide suspending agent:

[0034] It is prepared according to the mass percentage of emamectin B2 benzoate, fluthiazol sulfone and Achyranthes bidentata polysaccharide at 1:4:2. Take 2.86% of emamectin B2 benzoate, 11.43% of fluthiazol, 5.71% of Achyranthes knuckle polysaccharide, 4% of sodium lignosulfonate, and 1% of hydroxypolyethylene oxide block copolymer , 5% ethylene glycol, 1% magnesium aluminum silicate, 0.2% xanthan gum, and deionized water to make up, mix evenly, and grind with a sand mill to obtain a nematicidal suspension.

Embodiment 2

[0036] The present embodiment provides a kind of nematicide suspending agent:

[0037] It is prepared according to the mass percentage of emamectin B2 benzoate, fluthiazol sulfone and Achyranthes bidentata polysaccharide at 1:0.2:0.1. Take 15.4% of emamectin B2 benzoate, 3.1% of fluthiazol, 1.54% of Achyranthes knuckle polysaccharide, 4% of sodium lignosulfonate, and 1% of hydroxypolyethylene oxide block copolymer , 5% ethylene glycol, 1% magnesium aluminum silicate, 0.2% xanthan gum, and deionized water to make up, mix evenly, and grind with a sand mill to obtain a nematicidal suspension.

Embodiment 3

[0039] The present embodiment provides a kind of nematicide suspending agent:

[0040] It is prepared according to the mass percentage of emamectin B2 benzoate, fluthiazol sulfone and Achyranthes bidentata polysaccharide at 1:10:5. Take 3.1% of emamectin B2 benzoate, 31.2% of fluthiazol sulfone, 15.6% of Achyranthes knuckle polysaccharide, 4% of sodium lignosulfonate, and 1% of hydroxyl polyethylene oxide block copolymer , 5% ethylene glycol, 1% magnesium aluminum silicate, 0.2% xanthan gum, and deionized water to make up, mix evenly, and grind with a sand mill to obtain a nematicidal suspension.

Abstract

The invention relates to the technical field of pesticide preparation and in particular discloses a nematicide composition. According to the nematicide composition disclosed by the invention, methylamino abamectin B2 benzoate, tuensulfone and achyranthan are compounded, so that a prevention and treatment effect on plant nematodes is remarkably improved; because of different action mechanisms of effective components in the nematicide composition, the single selection pressure for nematodes is alleviated, nematode resistance occurrence can be overcome, and the nematode resistance occurrence velocity can be retarded; in addition, the prepared nematicide composition is small in dosage and excellent in effect lasting property, application times are reduced, the nematode resistance occurrence isfurther retarded, the production cost and the medicine cost can be lowered, the utilization rate of the nematicide composition is increased, environment pollution caused by the nematicide compositioncan be reduced, and the nematicide composition has a great popularization value.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a nematicide composition. Background technique [0002] Plant parasitic nematodes are a class of pathogenic microorganisms that are extremely harmful. They have a wide range of distribution, a wide variety, and strong environmental adaptability. They can parasitize in the roots, stems, leaves, seeds, sprouts, and fruits of plants. It causes mechanical damage to the host plant and plunders the host plant's nutrition, especially its esophageal gland secretion will cause a series of pathological changes in the host plant, and it will also infect the host plant together with other pathogenic microorganisms, causing compound diseases and resulting in yield loss. Globally, plant parasitic nematodes cause agricultural losses of more than 100 billion U.S. dollars every year, seriously restricting the development of agricultural economy. [0003] At present, there are not m...
