Embodiment 1

[0021] Example 1: 20% sulfone sulfone · amino oligosaccharin suspension concentrate (fluorosulfone sulfone: amino oligosaccharin = 1: 1)

[0022] Made according to the conventional process, wherein 10g of fluorene sulfone, 10g of amino oligosaccharin, 4g of sodium lignosulfonate (dispersant), 4g of ethylene glycol (antifreeze), 3g of bentonite (thickener), organic silicon Ketone (defoamer) 3g, deionized water to make up to 100g.

[0023] In the present embodiment, the weight ratio of fluorine sulfone and amino oligosaccharin can be changed between 20:1~1:20, and the weight percentage of the two can be changed between 5~60%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 2

[0024] Example 2: 30% sulfone sulfone · amino oligosaccharin water dispersible granules (fluoro sulfone : amino oligosaccharin = 5: 1)

[0025] Made according to the conventional process, fluorine sulfone 25g, amino oligosaccharin 5g, sodium alkylnaphthalene sulfonate (dispersant) 5g, sodium lignosulfonate (dispersant) 7g, sodium lauryl sulfate (wetting agent) agent) 2g, ammonium sulfate (disintegrant) 5g, light calcium carbonate (filler) to make up to 100g.

[0026] In the present embodiment, the weight ratio of fluorine sulfone and amino oligosaccharin can be changed between 20:1~1:20, and the weight percentage of the two can be changed between 5~80%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 3

[0027] Example 3: 21% sulfone sulfone · oligosaccharin wettable powder (sulfone sulfone: oligoaminosaccharin = 20:1)

[0028] Fluorene sulfone 20g, amino oligosaccharin 1g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin to make up to 100g.

[0029] In the present embodiment, the weight ratio of fluorine sulfone and amino oligosaccharin can be changed between 20:1~1:20, and the weight percentage of the two can be changed between 5~85%. Proportioning also is adjusted correspondingly thereupon, forms new embodiment.

Abstract

The invention discloses a nematode killing composition. Active components of the composition comprise fluensulfone and amino-oligosaccharin according to a mass ratio of 1:80-80:1. The composition can thoroughly control nematodes in the whole growth stage of crops, and has the advantages of good effect, low cost, substantial synergistic effect, and improvement of the resistance of crops to virus diseases, blight, epidemic diseases and other soil borne diseases.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a nematocidal composition containing sulfone and its application. 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] Fluorocene sulfone, CAS registration number: 318290-98-1, English name: Fluensulfone, product name: MCW-2, test code: BYI1921, MAI-08015, MAI-08016, other names: Nimitz, fluoro...
