Embodiment 1

[0022] Example 1: 30% pyraziflumid · pyrimethanil suspension concentrate (pyraziflumid: pyrimethanil = 1:2)

[0023] Made according to the conventional process, wherein pyraziflumid 10g, pyrimethanil 20g, sodium lignosulfonate (dispersant) 4g, sodium lauryl sulfate (wetting agent) 2g, ethylene glycol (antifreezing agent) 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 pyrimethanil can be changed between 20:1~1:20, the mass percentage of the two can be changed between 5%~80%, and the proportion of the auxiliary agent can also be changed. Make corresponding adjustments thereupon, form new embodiment.

[0025] It is also possible to replace pyrimethanil with imazalil, diethofencarb or procymidone to form a new embodiment.

Embodiment 2

[0026] Example 2: 60% pyraziflumid·procymidone water dispersible granules (pyraziflumid:procymidone=1:1)

[0027] Made according to the conventional process, wherein pyraziflumid 30g, procymidone 30g, 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 procymidone 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 procymidone with pyrimethanil, diethofencarb or imazalil to form a new embodiment.

Embodiment 3

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

[0031] Made according to the conventional process, wherein pyraziflumid 2g, imazalil 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 imazalil can vary between 20:1 and 1:20, and the mass percentage of the two can vary between 1% and 85%, and the ratio of the auxiliary agents can also be changed. Make corresponding adjustments thereupon, form new embodiment.

[0033] It is also possible to replace imazalil with pyrimethanil, diethofencarb or procymidone to form a new embodiment.

Abstract

The invention discloses a pyraziflumid-containing bactericidal composition. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is pyraziflumid; the active ingredient B is selected from any one of pyrimethanil, imazalil, diethofencarb or procymidone; the mass ratio of active ingredient A and the active ingredient B is 50:1 to 1:50. The composition disclosed by the invention can be used for preventing and controlling the diseases of a plurality of crops, such as vegetables, fruit trees and flowers, particularly, the diseases, such as botrytis, which are caused by high fungi, has a good preventing and controlling effect, and has the characteristics of wide bacteriocidal spectrum, low medicine using amount, obvious synergistic effect and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a fungicidal composition containing pyraziflumid and its application for preventing and treating crop diseases, and belongs 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...
