Embodiment 1

[0022] Example 1: 24% pyraziflumid · fluazinam suspension concentrate (pyraziflumid: fluazinam = 1:2)

[0023] Made according to the conventional process, wherein pyraziflumid 8g, fluazinam 16g, sodium lignosulfonate (dispersant) 4g, sodium lauryl sulfate (wetting agent) 2g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 0.15g, organic silicone (defoamer) 0.4g, deionized water to make up to 100g.

[0024] In this embodiment, the weight ratio of pyraziflumid and fluazinam can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 5% to 80%. Make corresponding adjustments thereupon, form new embodiment.

[0025] It is also possible to replace fluazinam with iprodione or fludioxonil to form new embodiments.

Embodiment 2

[0026] Example 2: 50% pyraziflumid · iprodione water dispersible granules (pyraziflumid: fluazinam = 1:1)

[0027] Made according to the conventional process, wherein pyraziflumid 25g, iprodione 25g, 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 pyraziflumid and iprodione can vary from 50:1 to 1:50, and the mass percentage of the two can vary from 1% to 85%. Make corresponding adjustments thereupon, form new embodiment.

[0029] It is also possible to replace iprodione with fluazinam or fludioxonil to form new embodiments.

Embodiment 3

[0030] Example 3: 42% pyraziflumid · iprodione wettable powder (pyraziflumid: iprodione = 1:20)

[0031] Made according to the conventional process, wherein pyraziflumid 2g, iprodione 40g, sodium lauryl sulfate (wetting agent) 2g, sodium lignosulfonate (dispersant) 3g, NNO (dispersant) 5g, kaolin supplemented to 100g .

[0032] In this embodiment, the weight ratio of pyraziflumid and iprodione can vary from 20:1 to 1:20, and the mass percentage of the two can vary from 1% to 85%. Make corresponding adjustments thereupon, form new embodiment.

[0033] It is also possible to replace iprodione with fluazinam or fludioxonil to form new embodiments.

Abstract

The invention discloses a sterilization composition containing pyraziflumid, which includes active components A and B, wherein the active component A is the pyraziflumid and the active component B isany one selected from fluazinam, iprodione or fludioxonil, mass ratio of A:B is 50:1-1:50. The composition is used for preventing and treating diseases on crops, such as vegetables, fruit trees, flowers and the like, especially having excellent prevention treatment effect on diseases of gray mold caused by higher fungus. The sterilization composition has wide antibacterial spectrum, is low in useamount and has significant synergistic effect.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a bactericidal composition containing pyraziflumid and its application on crop diseases, belonging to the technical field of pesticides. Background technique [0002] pyraziflumid (test code: NNF-0721) is an SDHI fungicide developed by Nippon Agricultural Chemicals Co., Ltd., which has a good effect on powdery mildew, scab, gray mold, sclerotinia, and ring disease on rice, fruits and vegetables. The control effect, structural formula is as follows: [0003] [0004] Botrytis cinerea is a worldwide important fungal disease caused by Botrytis cinerea. It is harmful to various crops such as vegetables, strawberries, and grapes, and the damage is serious, bringing greater economic benefits to growers. loss. [0005] Chemical control has the characteristics of high efficiency, quick effect, convenience and high economic benefit. It is one of the main measures to control Botrytis cinerea...
