Embodiment 1

[0021] A fungicide for preventing and treating grape black pox, which is composed of the following components by weight: 10% of euconazole, 5% of urea, 3% of fatty alcohol sulfate, 1% of sodium alkylphenol polyoxyethylene ether sulfate, Fatty alcohol polyoxyethylene ether 6%, sodium lignosulfonate 4%, anhydrous sodium sulfate 5%, gelatin 3%, polyvinylpyrrolidone 1%, disodium hydrogen phosphate 2%, catechol 2%, kaolin Supplement to 100%, adjust pH to 5 with sodium hydroxide and citric acid. The components are firstly mixed evenly, ultrafinely pulverized by a jet mill, then granulated by a swing granulator, and dried at a low temperature of 70°C.

[0022] This embodiment is used to prevent and control grape black pox, the dosage is 30 g / ha, and the control effect is 93.05-98.88%.

Embodiment 2

[0024] A fungicide for preventing and treating grape black pox, which is composed of the following components by weight: 30% of eucumazole, 15% of urea, 15% of sodium lauryl sulfate, 10% of sodium lauryl sulfate, lauryl polyoxygen Sodium vinyl ether sulfate 3%, pull open powder 2%, calcium chloride 7%, potassium carbonate 3%, polyethylene glycol 6%, succinic acid 3%, epoxidized soybean oil 3%, bentonite supplemented to 100%, ammonia and phosphoric acid to adjust the pH to 7. The components are firstly mixed evenly, ultrafinely pulverized by a jet mill, then granulated by a swing granulator, and dried at a low temperature of 80°C.

[0025] This embodiment is used to prevent and control grape black pox, the dosage is 50 g / ha, and the control effect is 96.05-99.23%.

Embodiment 3

[0027] A fungicide for preventing and treating grape black pox, consisting of the following components by weight: 50% urea, 20% urea, 7% sodium lauryl sulfate, monoalkylphenyl polyoxyethylene succinic acid sulfonate Sodium phosphate 3%, lauryl polyoxyethylene ether phosphate 5%, sodium dodecylbenzene sulfonate 5%, sodium oleate 5%, calcium chloride 8%, polyacrylate 6%, glycerine Alcohol 3%, starch 6%, butyl glycidyl ether 3%, eugenol 2%, hydroquinone 2%, bentonite and white carbon black added to 100%, sodium hydroxide and citric acid to adjust the pH to 6. The components are firstly mixed uniformly, ultrafinely pulverized by a jet mill, then granulated by a swing granulator, and dried at a low temperature of 50-100°C.

[0028] This example is used to prevent and control grape black pox, the dosage is 20 g / ha, and the control effect is 97.05-98.87%.

Abstract

The invention discloses bactericide for controlling anthracnose of grapes. The bactericide comprises components in percentage by weight as follows: 10%-50% of bismerthiazol, 5%-20% of urea, 1%-10% of a wetting agent, 1%-30% of a dispersing agent, 2%-15% of a disintegrating agent, 0.5%-10% of an adhesive, 0.1%-8% of a stabilizer and the balance of filler, wherein the pH value is adjusted to 5-7 by a pH regulator. The bactericide for controlling anthracnose of the grapes has good dispersity, high suspensibility, good mobility, high disintegration speed, good thermal stability and long lasting period, is easy to package, convenient to store and use and low in environmental pollution and produces little dust; the utilization rate of effective ingredients is increased, and the use amount is reduced; the effect for controlling anthracnose of the grapes is good, and the control efficiency is higher than 90%; urea is added, so that the utilization rate of the bactericide effective ingredients is increased, and the efficacy of the bactericide is improved; nutrient elements are added during application of the bactericide, and growth of the grapes is promoted.

Description

technical field [0001] The invention relates to the technical field of grape planting, in particular to a fungicide for preventing and treating grape black pox. Background technique [0002] In the field of grape cultivation, preventing and controlling grape diseases and insect pests is an important step to improve grape yield. Grape black pox is a major disease of grapes, which mainly harms the green and tender parts of grapes such as fruit, fruit stems, leaves, petioles, new shoots and tendrils. After the leaf is damaged, there are small brown spots on the needles at the beginning, and then it develops into a yellowish-brown circular lesion with a diameter of 1-4 mm, and the middle part turns gray. Finally, the tissue of the diseased part dries up and hardens, and falls off into a perforation. The young leaves are often twisted after being injured. Shrunken and deformed; in the early stage of fruit infection, brown round spots appear, the center of the round spots is off-...
