Embodiment 1

[0023] Example 1: 10% sulfone sulfone · lentinan suspension concentrate (sulfone sulfone: lentinan = 1:1)

[0024] Make according to routine process, wherein fluorine sulfone 5g, lentinan 5g, sodium lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, organic silicone ( defoamer) 3g, and deionized water was added to 100g.

[0025] In this embodiment, the weight ratio of sulfone and lentinan can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 60%. The ratio is adjusted accordingly to form a new embodiment.

Embodiment 2

[0026] Example 2: 30% sulfone sulfone · lentinan water dispersible granules (sulfone sulfone: lentinan = 5: 1)

[0027] Made according to the conventional process, 25g of fluorine sulfone, lentinan 5g, sodium alkylnaphthalene sulfonate (dispersant) 5g, sodium lignosulfonate (dispersant) 7g, sodium lauryl sulfate (wetting agent) 2g, ammonium sulfate (disintegrant) 5g, light calcium carbonate (filler) to make up to 100g.

[0028] In this embodiment, the weight ratio of sulfone and lentinan can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 80%. The ratio is adjusted accordingly to form a new embodiment.

Embodiment 3

[0029] Example 3: 84% sulfone sulfone · lentinan wettable powder (sulfone sulfone: lentinan = 20:1)

[0030] Fluorene sulfone 80g, lentinan 4g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin to make up to 100g.

[0031] In this embodiment, the weight ratio of sulfone and lentinan can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 85%. The ratio is adjusted accordingly to form a new embodiment.

Abstract

The invention discloses a nematicidal disease-resistant composition and application thereof. The composition comprises the active ingredients of fluensulfone and lentinan, and the mass ratio of fluensulfone to lentinan ranges from 1:80 to 80:1. The composition has a significant synergistic effect, can prevent and treat nematodes of the whole crop growth period, can improve the immunity of crops and has a good preventing and treating effect on soil-borne diseases such as virus diseases and blight.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a nematicide and disease-resistant composition containing sulfone and its application in preventing and controlling crop diseases, and belongs to the technical field of pesticides. Background technique [0002] Plant-parasitic nematodes mainly include: root-knot nematodes, reniform nematodes, heterodermal nematodes, breviphyllous nematodes, sciatica, long needle nematodes, sword nematodes, burr nematodes, and umbrella syringian nematodes. Nematodes not only directly harm host plants, but also transmit bacteria and viruses. Chemical control plays an important role in the control of nematodes, but most of the chemical nematicides currently used are highly toxic pesticides, which have many problems such as high toxicity, serious environmental pollution, insignificant control effect, and easy resistance of nematodes. . [0003] The proportion of plant virus diseases in plant diseases is s...
