Embodiment Construction

[0009] 1. Agricultural measures. Rotation with vegetables such as melons, solanaceous fruits, leeks, garlic, and green onions is implemented for 1 to 2 years in diseased areas. Choose a plot with relatively high terrain and good drainage for planting. If it is a low-lying land, it should be cultivated with a small high-border or high-border. Apply adequately decomposed manure, and increase the application of phosphorus and potassium fertilizers to improve plant disease resistance. The planting density should be appropriate. Water scientifically to prevent flooding, and drain water in time after rain. Protect the ground to strengthen the ventilation, reduce the humidity, and prevent the leaf surface from condensation. Clean the fields in time, take the diseased leaves and disabled bodies out of the field and bury them deeply or burn them to reduce the spread of pathogens in the fields.

[0010] 2. Chemical control. In the early stage of the disease, use 800 times liquid of 25...

Abstract

The invention relates to a novel technology for preventing and treating white rust of rape. The novel technology is characterized in that a purpose of preventing and treating white rust of rape can be realized by virtue of processes of crop rotation, rational application of a fertilizer, proper close planting, reasonable irrigation, field management, agent prevention and treatment and the like, and is suitable for preventing and treating white rust of rape.

Description

Technical field [0001] The invention relates to the field of vegetable planting, in particular to a new technology for the prevention and treatment of rape white rust. Background technique [0002] Rape white rust disease is manifested as leaf damage, small light green spots grow on the front, and then gradually turn yellow-green to yellow spots, and on the back of the leaves, there are slightly raised white near-circular or irregular-shaped spots. In severe cases, the lesions develop one after another, covering the whole leaf. After maturity, the lesions rupture and emit white powder. The leaves are uneven and turn yellow and die. Petioles, stems, and pedicels can also be damaged. The damaged parts are hypertrophy, twisted, deformed, and white spots are also produced. The pods are injured, swollen and deformed, and they are not full or firm. In this way, reducing production will affect its commodity value and edible value. Summary of the invention [0003] In order to solve t...
