Embodiment 1

[0065] Weigh 30% captan, 10% pyraclostrobin, 4% TERSPERSE 4894, 1.5% TERSPERSE 2500, 2% TERSPERSE 2020 (produced by Huntsman, USA), 1% magnesium aluminum silicate, 0.2% xanthan Glue, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), 2% triphenyl phosphate, deionized water to 100% parts by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 40% captan pyraclostrobin suspension concentrate.

Embodiment 2

[0067]Weigh 24% captan, 12% trifloxystrobin, 1% diffusing agent NNO, 3% agricultural milk 700#, 2% agricultural milk 1601#, 2% TERSPERSE 2500, 0.3% xanthan gum, 5% propylene glycol, 0.5 % benzoic acid, 0.5% silicone defoamer, 1% epichlorohydrin, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare 36% captan trifloxystrobin suspension concentrate.

Embodiment 3

[0069] Weigh 2% captan, 1% syringstrobin, 2% TERSPERSE 2020, 2% Span-60#, 2% Tween-60#, 1% TERSPERSE 2500, 0.5% white carbon black, 0.3% xanthan Glue, 5% ethylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer, 1% epichlorohydrin, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 3% captan-syringstrobin suspension.

Abstract

The invention discloses a sterilizing composite containing captan. The sterilizing composite comprises an effective and active component, wherein the effective and active component of the sterilizing composite consist of captan as a first active component and methoxyl acrylate bactericide from pyraclostrobin, trifloxystrobin and coumoxystrobin as a second active component; the weight ratio of the first active component to the second active component is 1:10-20:1, and preferred as 1:5-10:1. The sterilizing composite can be prepared into an agriculturally-allowable suspending agent, a suspending emulsion, a suspending seed coating agent, a micro-capsule suspending-suspending agent and seed-treatment dispersible powder. The sterilizing composite disclosed by the invention has the advantages that the components are reasonable, the sterilizing effect is good, the medicine use cost is low, and the activity and the sterilizing effect are not in simple superposition of various components. Compared with the traditional single preparation, the sterilizing composite disclosed by the invention not only has an obvious sterilizing effect, but also has an obvious synergistic action, has no pollution to crops, is good in safety, meets the requirement of safety of pesticide formulations, and has obvious preventing effects on wheat powdery mildew, rice sheath blight diseases, cochliobolus miyabeanus, damping off, vegetable pythium aphanidermatum and downy mildew.

Description

Technical field [0001] The present invention relates to a bactericidal composition, particularly a methoxyacrylate fungicide containing captan as the first active ingredient and selected from the group consisting of pyraclostrobin, trifloxystrobin and syringostrobin as the second active ingredient. A bactericidal composition with active ingredients belongs to the technical field of compound pesticides. Background technique [0002] Captan, English name is Captan, chemical name: N-trichloromethylthio-1,2,3,6-tetrahydrophthalimide. Captan is a broad-spectrum, low-toxic fungicide that mainly has a protective effect and also has a certain therapeutic effect. It can prevent and control various crop diseases on fruit trees and vegetable crops, such as pear tree scab, grape downy mildew, tomato early blight, pepper anthracnose, etc. Captan has been used for many years, and the problem of resistance is very prominent. [0003] Methoxyacrylic acid fungicides are newly developed fu...
