Plants became infected, and irregular water-like lesions were found on stems and shoots. The lesions turned gray or brown. The lesions spread around the stems and shoots for one week. The upper branches and leaves wilted and died, and the diseased surface had gray moldy material. Low temperature, low light, and high humidity are conducive to disease. It can be prevented with 75% Dakkonine WP 600 times, with 65% Tamycin WP 1000 times, 45% Tex Multisuspension 1000X, 50% acetaminophen WP 600X etc. Prevention.

Prolonged cold or frost prone to occur. In addition to strengthening the greenhouse moisturizing, dehumidification work, spray cold resistance agent, can be used Kang Kang 7500 times, or love to receive, guarantee more income, or brown sugar, 50 grams plus 15 grams of potassium dihydrogen phosphate plus 1 bucket of water spray.
