Problems solved by technology

[0008] However, in actual agricultural production, underground pests and nematodes often occur mixedly on crops, requiring repeated use of pesticides for control, which increases the use of pesticides, increases the production cost of crops, and increases pesticide residues on crops, increasing the environmental pollution

Embodiment 3

[0028] Formulation example 3: 20% fluthiazol-diazinon suspension seed coating.

[0029] Fluthiafur sulfone 5%, diazinon 15%, alkylphenol polyoxyethylene ether 2%, acrylic acid homopolymer sodium salt 2%, glycerol 4%, polydimethylsiloxane 0.1%, sodium benzoate 0.5%, sodium carboxymethylcellulose 2%, xanthan gum 1%, acid scarlet 1%, deionized water to make up 100%. Mix the above active ingredients, wetting agent, dispersant, antifreeze agent, defoamer, preservative, film forming agent, thickener and warning color evenly, and grind them in a sand mill for 3 to 4 hours, so that the particle size is all within 5 μm Next, the 20% fluthiazol-diazinon suspension seed coating agent can be obtained by filtering.

[0030] Formulation Example 4: 20% fluthiazol·chlorpyrifos microcapsule suspension.

[0031] Fluthiazol 4%, chlorpyrifos 16%, tolyl isocyanate 10%, cyclohexanone 20%, acryl polyether 5%, fatty acid polyoxyethylene ester 3%, sodium hydroxide 2%, deionized water to make up to 1...

Embodiment 5

[0032] Formulation example 5: 22% fluthiazol·phoxim microcapsule suspension.

[0033] Fluthiafur sulfone 2%, phoxim 20%, cresyl isocyanate 10%, cyclohexanone 20%, acryl polyether 5%, fatty acid polyoxyethylene ester 3%, sodium hydroxide 2%, deionized water to make up to 100%. Mix the above effective ingredients, polymer capsule wall materials, and solvents to dissolve them into a uniform oil phase. Under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifiers, dispersants, and pH regulators. Make up with deionized water, the two materials react at the oil-water interface to form a polymer capsule wall, and then the 22% fluthiazol-phoxim microcapsule suspension can be prepared.

[0034] Formulation example 6: 18% fluthiazol-diazinon microcapsule suspension.

[0035] Fluthiafur sulfone 5%, diazinon 13%, tolyl isocyanate 10%, cyclohexanone 20%, acryl polyether 5%, fatty acid polyoxyethylene ester 3%, sodium hydroxide 2%, deionized water to ma...

Embodiment 16

[0054] Formulation Example 16: 60% fluthiazol·chlorpyrifos water-dispersible granule.

[0055] Fluthiazol sulfone 20%, chlorpyrifos 40%, octyl sulfosuccinate sodium salt 5%, fatty alcohol polyoxyethylene ether sodium sulfate 10%, sodium sulfate 2%, and diatomaceous earth make up 100%. Mix the above-mentioned effective ingredients, wetting agent, dispersant, disintegrating agent and filler uniformly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, and sieving, that is 60% fluthiazol·chlorpyrifos water dispersible granules can be obtained.

Abstract

The invention discloses a pesticide composition containing fluensulfone and organophosphorus insecticide. The composition comprises a first effective ingredient fluensulfone, a second effective ingredient organophosphorus insecticide and common pesticide auxiliaries, wherein the organophosphorus insecticide is one of chlorpyrifos, phoxim and diazinon; and the weight ratio of fluensulfone to organophosphorus insecticide is (40:1)-(1:40) Massive indoor and outdoor tests indicate that the pesticide composition has a remarkable synergetic effect, and has a preventing and controlling effect on underground pests and nematodes on crops remarkably superior to those of independent application of single agent, so that the pesticide usage is reduced, residues of pesticide on crops are reduced, environmental pollution is reduced, and generation of drug resistance of pests and insects is retarded.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a pesticide composition with fluthiazol and organophosphorus insecticides as active ingredients, which is used to prevent and control underground pests and nematodes of crops. Background technique [0002] Fluensulfone: a new type of non-fumigation nematicide, which has a good control effect on nematodes at various growth stages. Usually, the mode of action of non-fumigation nematicides is to make nematodes lose their ability to move, but after a period of time, nematodes It will recover, while fluthiazol will completely kill the nematodes. The time for fluthiazol to enter the soil is only 12 hours, while the time for other nematicides to enter the soil is generally about 5 days. [0003] Chlorpyrifos (chlorpyrifos): belongs to organophosphorus insecticides, has contact killing, stomach poisoning and fumigation effects, and is used to control aboveground and un...
