Common seedling infestation diseases include damping-off, blight, anthrax, and leaf spot. This kind of disease occurs quickly and spreads to each other, often resulting in lack of seedlings and ridges. It is necessary to pay attention to prevention and control. Cultivation and disease prevention adhere to the rotation system, and do not continuously cultivate the same kind of seedlings in the same nursery, and do not use nursery plots in low-lying, easily recognizable plots. There should be appropriate irrigation and drainage facilities in the nursery plots. Fine soil preparation, timely sowing, pay attention to the depth of sowing, cover soil is not too thick, so that the seed can quickly sprout seedlings, can enhance the resistance of seedlings. Increase the maturity of organic fertilizers to meet the requirements of seedlings for various nutrient elements, so that seedlings grow robustly. Urinary Tract Infection Test Strips 1. who are we?

First, the seeds were sown before sowing, and the weak seeds were eliminated. Because of the low germination rate of the weak seeds, they were often the primary sources of infection. Spray the seeds with 0.5% formalin, mix and cover the stack for 2 hours, spread out, and run until the formalin gas has run clean. Or first soak the seed in cold water for 4-6 hours, then soak it in warm water of 49-50°C for 10 minutes, remove it and allow it to dry.
Second, the soil is treated 2 to 3 weeks before sowing to loosen the soil. Formalin is used in 40 ml of water to 1 to 3 kg per square meter (the amount of water added depends on the soil moisture), and after being wetted, the film 4 to 5 is covered. Days, about 2 weeks after the removal of the film, the seeds are ready to be volatilized and re-seeded, or 50% carbendazim WP or 10% thiophanate-methyl or 50% thiram or 70% trichloronitrobenzene are used as bactericides. 8 to 10 grams per square meter, add 10 to 15 kilograms of dry fine soil, and mix the soil. Before planting, one-third of the medicinal soil should be spread evenly as bedding, and the remaining three points after sowing. The second drug soil as a cover soil, and keep the soil moist.
Third, pharmacological treatment for root disease, if a small number of diseased plants found in the nursery, after removal can be sprayed with ammonia disinfection agent. The formula is: 2 parts of copper sulfate, 11 parts of ammonium carbonate or 2 parts of copper sulfate, 15 parts of ammonium sulfate, 4 parts of slaked lime, fully mixed and sealed for 24 hours. When used, take 1 part of the drug plus 400 parts of water spray, and spray it 7 to 10 days later. When the humidity on the soil surface is too high after spraying, the wood ash can be used to reduce the humidity. For leaf spot disease and other above-ground diseases, 1% Bordeaux mixture, 50% dexamethasone, and zesin can be used as the bactericide. Spray every 7 to 10 days until the disease is controlled.
