Embodiment 1

[0032] Weigh 7% folpet, 7% fenflufen, 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 30 minutes, and sanded with a sand mill to a particle size of D 90 A 14% fenflufen·folpet suspension concentrate was prepared after the thickness was less than 10 μm.

Embodiment 2

[0034] Weigh 20% folpet, 2% fenflufen, 3% polycarboxylate, 2% phenethylphenol polyoxyethylene ether phosphate, 2.5% sodium carboxymethylcellulose, 3% polyethylene Glycol, 0.2% potassium sorbate, 0.1% octanol, and deionized water are added to 100% by weight. 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 the thickness is less than 10 μm, a 22% fenflufen·folpet suspension concentrate is prepared.

Embodiment 3

[0036] Weigh 15% folpet, 6% fenflufen, 4.2% TERSPERSE 2700 (produced by Huntsman, U.S.), 3% sodium lignosulfonate, 2.6% pull open powder BX (dibutyl naphthalene sulfonic acid sodium), 2% sodium lauryl sulfate, 1% polyvinyl alcohol (PVA molecular weight 2000), 3% sucrose, 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, ultrafine airflow pulverization, mixing, and granulating steps to prepare 21% fenflufen·foldol water-dispersible granules.

Abstract

The invention relates to a synergistic interaction composition containing folpet and fenpyrazamine and application of the composition. Effective active ingredients include folpet and fenpyrazamine, the weight ratio of folpet to fenpyrazamine is 1:20-20:1, preferentially is 1:10-10:1 and further preferentially is 1:5-5:1. The composition can be prepared into agriculturally-allowed emulsion in wateror wettable powder or a suspending agent or water granules. The components are reasonable, the sterilization effect is good, and the activity and sterilizing effects are not simply overlapped by activities of the components; compared with an existing single preparation, the composition has the remarkable synergism besides the remarkable sterilizing effect, and the crop security is good. The goodprevention effect on cucumber downy mildew and botrytis cinerea is achieved, and the remarkably synergic effect on the diseases is achieved by compounding folpet and fenpyrazamine.

Description

technical field [0001] The invention relates to a bactericidal composition safe for crops, which contains fendand and fenpyridone, 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, tomato gray mold, melons Downy mildew, etc. It is safe and has no phytotoxicity to crops at the recommended dosage. [0003] Amphetamine, chemical name: 1-[(2-propenylthio)formyl]-2-isopropyl-4-(2-methylphenyl)-5-amino-1H-pyrazole- 3-keto, English common name: fenpyrazamine, molecular formula...
