Embodiment Construction

[0010] 1. Agricultural measures, apply enough basal fertilizer to enhance the host's disease resistance. Implement crop rotation for more than 2 years. Harvest at the right time and store at low temperature, especially for onions. Harvest when the top of the onion is mature. After harvesting, dry the outside of the bulb and store it in a cellar. The temperature in the cellar is controlled at 0-5°C and the relative humidity is below 65%.

[0011] 2. For seed disinfection, use disease-free seeds. If necessary, the seeds are soaked in 300 times of 40% formaldehyde for 3 hours, and washed in time after soaking. The bulbs can be sterilized by soaking in warm water at 40-45°C for 1.5 hours.

[0012] 3. Chemical control, spray 75% chlorothalonil wettable powder 500-600 times liquid at the early stage of the disease, or 64% anti-virus alum wettable powder 500 times liquid, or 50% promethadin wettable powder 1500 times liquid, every 7 ~ Once every 10 days, 3 to 4 times of continuous ...

Abstract

A novel method for the prevention and treatment of onion purple spot is characterized in that by applying enough organic fertilizers, sowing in a suitable period, adding a phosphorus fertilizer and apotash fertilizer in the growth period, rationally irrigating and removing diseased plants in time, the purpose of preventing and treating onion purple spot can be achieved. High yield and high efficiency can be achieved, and the method is suitable for prevention and treatment of onion purple spot.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a new method for preventing and treating onion purple spot disease. Background technique [0002] Onion purple spot disease mainly damages leaves and pedicels. It appears as small water-soaked white spots at first, and then becomes light brown circular or spindle-shaped slightly sunken spots, which continue to expand and turn brown or dark purple, often with yellow halos around them. The disease grows dark brown Or black-gray mold with concentric rings, the diseased part continues to expand, causing the whole leaf to turn yellow, die or break. The peduncle of the seed plant has a high incidence rate, causing the seeds to shrink and fail to fully mature. Like this, reduce output, affect its commodity value and edible value. Contents of the invention [0003] In order to solve the traditional technical problem of preventing and treating onion purple spot, the invention invents...
