The water stains and brown spots are contiguous, and they quickly turn black and collapse. Falling flowers and falling fruit. The most common is pepper. For prevention and treatment, the first is seed treatment. Use 10% formaldehyde (formalin) to soak seed for 30-60 minutes, remove and rinse, and then sow. The second is that in July-August each year, 98% of copper sulphate is used to irrigate the root of 0.8-1.2 kilograms of water per mu and 100-150 kilograms of water. Third, at the beginning of the onset period, the plants were sprayed with 400-600 times of 40% aluminum phosphonium WP, or 400-600 times of 25% of the cream, and roots were also irrigated with 400 times the amount of Borax, and the plants were sprayed 600 times. With 22% cream urea zinc WP 500 to 650 times, spray every 7 days, once, and spray 2 or 3 times; 50% carbendazim WP 500 to 800 times spray; 64% antivirus 500 times spray.
