Composition for preventing grape veraison disease

Abstract

The invention belongs to the field of plant disease control and particularly discloses composition for preventing grape veraison disease. The composition is prepared from the following raw materials in parts by weight: 50-60 parts of soybean cakes, 8-12 parts of sesame dregs, 20-30 parts of pig manure, 5-10 parts of pigeon dung, 11-15 parts of plant ash, 9-13 parts of parthenocissus tricuspidata and 8-10 parts of Entireleaf Neoalsomitra. An application method of the composition comprises steps as follows: fermenting the soybean cakes and the sesame dregs to obtain a mixture I; powdering the parthenocissus tricuspidata and the Entireleaf Neoalsomitra, and mixing powder uniformly to obtain a mixture II; fermenting the pig manure and then uniformly mixing the pig manure with the pigeon dung to obtain a mixture III; mixing and uniformly stirring the mixture I, the mixture II and the mixture III to obtain mixed fertilizer; digging a first circular trench in a position 0.5 m away from a plant, and applying 20 kg of the mixed fertilizer; digging a second circular trench in a position 1 m away from the plant and applying 40 kg of the mixed fertilizer; digging a third circular trench in a position 2 m away from the plant and applying 70 kg of the mixed fertilizer. The composition for preventing the grape veraison disease can reduce the probability of the grape veraison disease, thereby improving the yield of grapes.

Description

technical field [0001] The invention relates to the field of plant disease prevention and control, in particular to a composition for preventing grape rot and an application method thereof. Background technique [0002] Grape is one of the oldest and most widely distributed fruits in the world. Its berries are mostly round or oval, and the color varies with the variety. Grapes have high nutritional value and can be made into grape juice, raisins and wine. Large grains, thick skin, less juice, more water, easy separation of skin and flesh, sweet and sour taste, a thin layer of skin on the outside of the flesh, a thin frost on the outside of the skin, and some varieties are seedless. Grapes can be used as raw fruit, wine or raisins. [0003] Grape discoloration disease, also known as water pot disease, mainly manifests on the fruit ears, and usually manifests symptoms after fruit sizing to the ripening stage. Often, several to dozens of grains at the tip of the fruit ear sho...
