The mold rot mainly occurs in the protected area, and it damages the fruit. At the early stage of fruit onset, brown spots and small spots of water immersion are formed, and the lesion gradually expands and shows a wet rot. Lesions are round, nearly round, 10-30 mm in size, and even larger, light brown. When the humidity is high, the diseased part of the disease begins to be white, and it turns to black and green velvety mildew.
Agricultural measures to cultivate disease-free and strong seedlings, strengthen fertilizer and water management, apply sufficient manure, timely fertilizer application, control irrigation, strengthen ventilation, and reduce humidity. The use of non-drip film, often remove dust on the film, increase light transmittance. After the fruit matures, it is found that the diseased fruit is removed promptly and buried deeply.
Pharmacological control, prevention of plant cellular immune factors before the onset of disease, enhance plant resistance, can make viral DNA breakage and apoptosis. Strong immune function, induces interferon and active interleukin, inhibits residual virus replication. After the onset of the disease with targeted drugs plus a new high-fat membrane for effective control, spraying once every 7 days or so, continuous control 2 to 3 times.
