I. Common Diseases of Vegetable Seedlings The growth of vegetable seedlings is relatively weak, and it is vulnerable to the attack and death of many kinds of diseases, which brings great troubles to production. The common diseases of vegetable seedlings are roughly the following. 1. Phytophthora infestans seedlings infected before the emergence of bad species, the incidence of disease after the emergence of light brown spots on the stem base lesions, lesions around the stem for 1 week, after the soft, epidermal shedding, contracture of the disease, the stem was line shape. The onset of the disease is rapid, and the symptomatic symptoms in the upper part of the lesion are collapsed. 2. The onset of emergence of B. oleracea seedlings and the appearance of oval depressions in the stem base. One week of lesions around the stem causes contraction and dryness, wilting of the plants or death in erection, and generally do not fall down. 3. The incidence of wilt disease seedlings, yellowing and contracting stem base, cotyledon or whole plant wilt. During the wet period, the base of the stem was rotted and the victim suffered longitudinal fissures and a white or pink moldy layer grew on the surface. 4. This is because of the physiological disease caused by low temperature and humidity. Underground roots are rust-colored, perishable, and no new roots are found. The edges of the aboveground leaves turn yellow, prone to scorch, and the seedlings are wilting and easy to pull up. 5. Diseases of leaves and stems of gray mold. The lesions were rotted with water stains, and when the humidity was high, a large amount of brownish brown mold layer was formed. The lesions were irregular and later dried up, often breaking off from the diseased part. Second, the prevention and treatment of common diseases 1, selection of disease-resistant varieties for different diseases, different crops, selection of disease-resistant varieties. For example, purple round eggplant was more resistant to damping-off than cucumber seedlings. Jinyan No. 6 was resistant to cucumber wilt. 2. Seed treatment Seed borne with bacteria is an important factor leading to the onset of seedling stage, with particular emphasis on seed treatment prior to sowing, which can be immersed in warm soup and soaked in two ways. Before sowing, use 75% chlorothalonil WP + 40% double wettable powder (1:1) to soak seeds for 30 minutes, and sow after cleaning. 3, the choice of non-bed soil can be used nutrition seedlings or plastic sets of seedlings to facilitate the cultivation of strong seedlings, enhance host resistance. Seedling nursery can be used with 360 milliliters of formalin plus 9-18 kilograms of water per square meter, spread in seedlings 20 days before sowing, film fumigation 4-5 days, uncovered film can be sown two weeks after sowing. 4, to strengthen the management of seedling mites is to avoid the emergence of low temperature and high humidity conditions, keep the temperature of seedling mites at about 20 °C, proper control of watering, pay attention to ventilation and humidity, when the humidity is too large, it can be applied to the grass in the ash and dry soil, The diseased plant was found to be removed promptly. 5, chemical control can be used 75% of chlorothalonil or 75% of mancozeb 500 times, or 64% of antiviral 600 times spray to prevent damping-off and early blight; with 50% thiophanate-methyl 400 times or with 30% DT500 times spray can prevent blight; with 50% of the 800 times solution of quick-Kling or 50% of prohexine 800 times spray can control gray mold; copper ammonium mixture (ie 10 grams of copper sulfate and ammonium carbonate or 550 grams of ammonium bicarbonate mix, closed stuffy 24 hours) 1 200 kg of water spray, can prevent blight and early blight.
