Comprehensive Prevention of Falling Blight of Nursery Tomatoes in Spring

Tomato cataplexy often occurs after the emergence of seedlings and before the true leaves have yet to unfold. After the infection, pathogenic bacteria develop dark stains on the base of the young shoots, which then expand around the stems and gradually shrink into thin lines, causing the seedlings to remain on the ground. Loss of supporting ability and inverted shape, when the humidity of the seedbed is high, white cotton flocculent hyphae often appear on the surface of the diseased seedlings or nearby beds. Seedlings are low temperature and high humidity, and seedlings are susceptible to disease when they grow slowly. The main control methods are as follows:

1. Use rapid seedling or soilless seedling methods to disinfect bed seedlings and greenhouses. Strengthen the management of seedbeds to see if the seedlings release moderate amounts of moisture in due course so as to avoid the occurrence of low temperature and high humidity conditions and not to water in rainy days.

2. Spray 0.1%-0.2% potassium dihydrogen phosphate, 0.05%-0.1% calcium chloride during seedling period to improve disease resistance.

3, seedbed disinfection, per square meter seedbed can choose 40% nitrochlorobenzene 9-10 grams, add fine soil 4.0 to 4.5 kg mix, soaked before the broadcast of water, until the water infiltration, take 1/3 Medicinal soil is sprinkled on the surface, and the rest of the soil is covered with the remaining 2/3 of the soil. Can also be used before the onset or early onset with 72.2% Preclosure 400 times spray, 2 to 3 liters of liquid per square meter.

4, timely chemical control, can be sprayed 72% Kelu wettable powder 600 times, or 72% Ankegan zinc wettable powder 1000 times, or% Lei Duomier wettable powder 500 times, or 75% 100% Bacterial Widow WP 600 times, or 64% anti-virus WP 500 times, 72.2% PREC water 600 times, every 7 to 10 days, depending on the condition of prevention 1 or 2 times.
