Problems solved by technology

However, the current production and use costs of fluorene sulfone are relatively high, and there is a great risk of resistance when used alone for a long time
[0004] Iprodione is a low-toxic fungicide, which is effective against many fungal diseases such as gray mold, early blight, black spot, etc. It is reported in the patent CN101669517B that it has certain killing activity against plant nematodes, but Iprodione is used alone The effect is not ideal, and it is easy to induce nematode resistance, which is not conducive to the development of sustained effect

Embodiment 1

[0019] Example 1: 40% sulfonesulfone · iprodione suspension concentrate (fluphensulfone: iprodione = 1:1)

[0020] Made according to the conventional process, wherein 20g of sulfone sulfone, 20g of iprodione, 4g of sodium lignosulfonate (dispersant), 4g of ethylene glycol (antifreeze), 3g of bentonite (thickener), organic silicone (defoamer) 3g, deionized water is added to 100g.

[0021] In this example, the weight ratio of sulfone and iprodione can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 60%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 2

[0022] Example 2: 30% sulfonesulfone·iprodione water dispersible granule (fluphensulfone: iprodione=5:1)

[0023] Made according to the conventional process, 25g of fluorine sulfone, 5g of iprodione, 5g of sodium alkylnaphthalene sulfonate (dispersant), 7g of sodium lignosulfonate (dispersant), sodium lauryl sulfate (wetting agent) ) 2g, ammonium sulfate (disintegrant) 5g, light calcium carbonate (filler) to make up to 100g.

[0024] In this example, the weight ratio of sulfone and iprodione can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 80%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 3

[0025] Example 3: 60% sulfonesulfone·iprodione wettable powder (fluphensulfone: iprodione=1:5)

[0026] Fluorene sulfone 10g, iprodione 60g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin to make up to 100g.

[0027] In this embodiment, the weight ratio of sulfone and iprodione can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 85%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Abstract

The invention discloses a nematicide composition. The active ingredient of the composition is composed of sulfone and iprodione, and the mass ratio of the two is 1:80-80:1. The composition of the invention has remarkable synergistic effect, has better control effect on nematodes, has good effect and low cost.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a nematicidal 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] Fluoroline sulfone, CAS registration number: 318290-98-1, English name: fluensulfo...
