Embodiment 1
[0040] Weigh 20% folpet, 2.3% mandestrobin, 6% polycarboxylate, 3% sapinberry powder, 0.1% C10-20 saturated fatty acid, 1.5% β-cyclodextrin, 1.9% ethylene glycol, Add ionized water to 100%, mix the above raw materials, disperse at high speed for 30 minutes, and grind to particle size D with a sand mill 90 After less than 10 μm, a 22.3% sterile Dan·mandestrobin suspension was prepared.
Embodiment 2
[0042] Weigh 20% folpet, 4.5% mandestrobin, 5% calcium dodecylbenzenesulfonate, wetting and penetrating agent F1.4%, Nongru 400#6%, xanthan gum 1.3%, propylene glycol 1.7%, silicon Add 0.2% of ketone compound and water to 100%. The above raw materials are mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to a particle size of D 90 After less than 10 μm, a 24.5% sterile Dan·mandestrobin suspension was prepared.
Embodiment 3
[0044] Weigh 8% folpet, 7% mandestrobin, 7% alkyl aryl polyoxyethylene ether, 5.5% silkworm excrement, 2.3% ammonium sulfate, 3.8% white carbon black, add kaolin to 100%, the above raw materials are conventionally prepared into water The method for dispersing the granule is to prepare the 15% sterilized mandestrobin water-dispersible granule through the steps of mixing, ultrafine airflow pulverization, mixing and granulation.

Abstract
The invention relates to a sterilizing composition containing folpet and Mandestrobin and application thereof. The effective components of the sterilizing composition include the folpet and the Mandestrobin, wherein the weight ratio of the first active component and the second active component is 1:20-40:1, further preferably 1:10-20:1, and more preferably 1:2.5-10:1. The sterilizing composition can be prepared into preparations such as agriculturally-allowable emulsion in water, wettable powder, a suspending agent or water-dispersible granule. The sterilizing composition has the advantages that the components are reasonable, the sterilizing effect is good and the activity and the sterilizing effect are not simple superposition of the activities of all the components; compared with the existing single preparation, the sterilizing composition not only has obvious sterilizing effect, but also has an obvious synergistic effect and has good safety to crops. The sterilizing composition plays a better role in preventing botrytis cinerea and cucumber downy mildew, and has an obvious synergistic effect for preventing the diseases by complexing of the folpet and Mandestrobin.
Description
technical field [0001] The invention relates to a bactericidal composition safe for vegetable crops, which contains folpet and Mandestrobin, and belongs to the technical field of compound pesticides. Background technique [0002] Folpet, chemical name: N-trichloromethylthiophthalimide, English common name: folpet, trade name: Folpan, Cuprofal, Fobeci, Sygan PM, Syphal PM, CAS registration number is 133-07 -3, is a fungicide developed by Chevron Chemical Company. At present, Fendan is mainly used to prevent and control grain and oil crops, vegetables, fruit trees and other crop diseases, such as rice sheath blight, rice blast, wheat rust, tobacco anthracnose, peanut leaf spot, rape sclerotinia, wheat powdery mildew, melon frost Mildew, etc., at the recommended dose, it is safe and has no phytotoxicity to crops. [0003] Mandestrobin, chemical name: (RS)-2-methoxy-N-methyl-2-[α-(2,5-dimethylphenoxy)-o-tolyl]acetamide, CAS accession number 173662-97 -0, a methoxyacrylate fun...
