Embodiment 1

[0010] The percentages (%) of the effective ingredients of the plant sterilization composition are: carbendazim 22.5, mancozeb 14.35, metalaxyl 1.125, dixon 18.75, and pharmaceutical grade potassium permanganate 5. The prepared fungicide can be used for soil treatment, root irrigation and foliar spraying. To prevent and cure diseases such as blight and damping-off at the seedling stage of flue-cured tobacco, use 200 grams of medicine per acre, add 50 kg of water, and spray on the seedbed. 10 days before the emergence of the seedlings, apply 100 to 150 grams of medicine per acre and add 50 kg of water. Spray a kilogram on the seedlings to prevent black shank and root black rot of flue-cured tobacco. When transplanting flue-cured tobacco, apply 200 grams of medicine per mu, mix 10-20 kilograms of fine soil and apply it in the pond, or 15-30 days after the flue-cured tobacco survives. Then use 150 grams of medicine and add 50 kg of water to spray.

Embodiment 2

[0012] Take 50% carbendazim wettable powder 45 kg, 70% mancozeb wettable powder 20.5 kg, 25% metalaxyl wettable powder 4.5 kg, 75% dixone powder 25 kg, medical high manganese 5 kilograms of potassium acid crystals, the mixing time is 8 minutes, after sampling inspection, weighing, packaging, sealing, and packing to obtain 100 kilograms of gray-yellow powdery plant sterilization composition. The product can be used to prevent and cure leaf diseases such as flue-cured tobacco brown spot and anthracnose. At the initial stage of onset, 150 grams of medicine per mu is sprayed with water and 50 kilograms of water. Afterwards, spray 1 to 2 times depending on the disease, pepper, watermelon, eggplant, tomato and other crop diseases Control can be applied according to the above methods.

Abstract

The invention relates to a plant sterilization composition and a preparation method thereof. According to the present invention, the plant sterilization composition contains metalaxyl, fenaminosulf, and pharmaceutic-grade potassium permanganate, and the effective components comprise 19-24% of carbendazim, 11-16% of mancozeb, 0.8-1.2% of metalaxyl, 15-20% of fenaminosulf, and 4-6% of pharmaceutic-grade potassium permanganate; carbendazim, mancozeb, metalaxyl, fenaminosulf and potassium permanganate crystal crushed and screened with a 100 mesh sieve are respectively weighed and fed, the ratio of the carbendazim to the mancozeb to the metalaxyl to the fenaminosulf to the pharmaceutic-grade potassium permanganate during the preparation is 19-24%:11-16%:0.8-1.2%:15-20%:4-6%, and various components are stirred for 4-12 min by using a mixer so as to obtain the plant sterilization composition.

Description

Technical field [0001] The invention relates to a composition type plant fungicide and a corresponding preparation method. Background technique [0002] Spicy pepper, watermelon, tomato, eggplant, etc. are widely grown cash crops, especially flue-cured tobacco has an important economic position. There are many factors that affect the yield and quality of these crops. Among them, disease is one of the main factors. Among the diseases, the most harmful are blight, damping-off, blight, black shank, root black rot, brown spot, and bacterial wilt. , Anthracnose, virus disease, etc. Moreover, the diseases on these crops often occur mixed and cross-infected during the same growth period or different growth periods, causing serious consequences. How to take effective prevention and control measures for the above-mentioned diseases is a difficult problem that has plagued people for a long time. Most of the bactericides used in the prior art are single-agent or binary mixtures, with a s...
