Embodiment 1

[0051] Example 1: 20.2% Shenzimycin Sclerotin Suspension Concentrate (1:100)

[0052] Components: Shenzimycin 0.2%, Sclerotin 20%, Acrylic Acid-Hydroxypropyl Acrylate Copolymer 3%, Sodium Octylphenol Polyoxyethylene Ether Sulfonate 3%, Ethylene Glycol 6%, XG 0.3%, Silicone defoamer 0.2%, sodium benzoate 0.4%, soft water make up to 100%.

[0053] Preparation method: Mix the components, mix them uniformly by high-speed shearing, and then sand them with a sand mill for 2-3 hours, so that the average particle size reaches 1-5 microns, and then 20.2% Shenzimycin bacteria can be prepared. Nuclear net suspending agent.

Embodiment 2

[0057] Embodiment 2: 25.5% Shenzimycin Sclerotin wettable powder (1:50)

[0058] Components: Shenzimycin 0.5%, Sclerotinia 25%, Sodium Lauryl Sulfate 5%, Sodium Lauryl Sulfate 5%, White Carbon Black 6%, Light Calcium Carbonate supplemented to 100%.

[0059] Preparation method: Mix all the components uniformly, first pass through mechanical pulverization, then jet pulverization, and then mix uniformly to prepare 25.5% Shenzimycin · Sclerotinia wettable powder.

Embodiment 3

[0063] Embodiment 3: 35% Shenzimycin · Sclerotia clean dry suspension concentrate (1:34)

[0064] Components: Shenzimycin 1%, sclerotium 34%, sodium lignosulfonate 8%, sodium lignonaphthalenesulfonate 6%, white carbon black 4%, sodium benzoate 0.2%, talcum powder 100%. An additional 150-200% of deionized water was added during preparation.

[0065] Preparation method: add 1.5-2.0 times the amount of water prepared by the preparation, mix the components, mix them evenly through high-speed shearing, and then sand them with a sand mill for 2-3 hours to make the average particle size reach 1-5 microns, dehydrate After drying, a 35% Shenzimycin·sclerotia net dry suspension can be prepared.

Abstract

The invention discloses a fungicide composition and application thereof, and relates to the technical field of pesticide compounding. Active ingredients of the fungicide composition comprise phenazine-1-carboxylic acid A and a fungicide B, wherein the fungicide B is selected from dimethachlon and tridemorph, and the weight ratio of the phenazine-1-carboxylic acid A to the fungicide B is (1:100) - (100:1). According to the fungicide composition, the compounded active ingredients A and B have remarkable synergism and can effectively reduce the application rate of each single reagent; expansion of a bacteriocidal spectrum and slowing of plant fungicide resistance are greatly facilitated, the effect preservation period can also be prolonged, and a remarkable promotional value exists. The fungicide composition can be added with other auxiliary ingredients, which are allowed to be used in pesticides, to be prepared into any agent, and can effectively prevent and control a rice sheath blight disease, rice blast, rice false smut, wheat rust, powdery mildew, wheat root rot, wheat sharp eyespot, soybean root rot, sclerotinia rot of colza, corn head smut, fusarium wilt, downy mildew, pestilence, bacterial angular leaf spot and the like.

Description

technical field [0001] The invention relates to a bactericidal composition and application thereof, in particular to a bactericidal composition containing shenzamycin, sclerotin or tridemorpholine as active ingredients and application thereof, and belongs to the technical field of pesticide compounding. Background technique [0002] In agricultural production, the healthy growth of crops is not only affected by insects and weeds, but also the prevention and control of diseases is very important. With the strengthening of environmental protection concepts and the implementation of sustainable development strategies, high efficiency, low toxicity, high activity, and low residue have become an inevitable trend in the development of pesticides. However, even if high-efficiency fungicides are used alone for a long time, it is easy to cause disease resistance, leading to problems such as increased dosage, reduced control effect, and shortened duration, which is not conducive to su...
