Embodiment 1

[0033] Weigh 5% oxafluconate, 25% folpet, 4% sodium dodecylbenzene sulfonate, 7.2% sodium lignosulfonate, 0.3% magnesium aluminum silicate, 0.7% organic bentonite, 5% propylene glycol, 0.1% sodium benzoate, 1% isoamyl alcohol, and deionized water are added to 100% by weight. The above raw materials are mixed, dispersed at high speed for 40 minutes, and sanded with a sand mill to a particle size of D 90 After the thickness is less than 10 μm, a 30% oxaconazole·folpet suspension concentrate is prepared.

Embodiment 2

[0035] Weigh 10% oxaflucone, 10% folpet, 3% polycarboxylate, 2% phenethylphenol polyoxyethylene ether phosphate, 2.5% sodium carboxymethylcellulose, 3% polyethylene glycol alcohol, 0.2% potassium sorbate, 0.1% octanol, and deionized water to 100% by weight. The above raw materials are mixed, dispersed at high speed for 50 minutes, and sanded with a sand mill to a particle size of D 90 A 20% oxafezone·folpet suspension was prepared after the thickness was less than 10 μm.

Embodiment 3

[0037] Take by weighing 3% oxafefenone, 31% folpet, 4.2% TERSPERSE 2700 (produced by Huntsman, U.S.), 3% sodium lignosulfonate, 2.6% pull open powder BX (sodium dibutylnaphthalene sulfonate) ), 2% sodium lauryl sulfate, 1% polyvinyl alcohol (PVA molecular weight 2000), 3% sucrose, and white carbon black added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, ie, mixing, ultra-micro airflow pulverization, mixing, and granulating steps to prepare 34% oxafefenone·folpet water-dispersible granules.

Abstract

The invention discloses an agricultural bactericidal composition containing folpet and famoxadone and applications thereof. The effective component comprises folpet and famoxadone. The weight ratio offolpet to famoxadone is 1:20-30:1, preferably 1:15-20:1, and more preferably 1:1-20:1. The bactericidal composition can be made in agriculturally acceptable dosage forms such as emulsion in water, wettable powder, suspending agent, water dispersible granule, or the like. The formula is reasonable, the bactericidal effect is good, the activity and bactericidal effect are better than total activityand bactericidal effect of all components; compared with a single component preparation, the bactericidal effect is enhanced, an obvious synergistic effect is generated, and moreover, the bactericidal composition is safe for crops and has a prominent control effect on early blight of tomatoes and late blight of potatoes.

Description

technical field [0001] The invention relates to a bactericidal composition safe for crops, which contains fendand and oxafeconone, 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, potato late blight, melon frost Mildew, etc., at the recommended dose, it is safe and has no phytotoxicity to crops. [0003] Famoxadone, chemical name: 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-dione, English common name: famoxadone , single-dose trade name: Yibao, is a new ...
