1976～1985的十年期间,对上海棉花烂铃的发生和防治进行了系统观察和研究,还就防治策略进行了探讨。上海棉花烂铃病害主要为寄生性病害疫病和炭疽病,个别年份有角斑病。弱寄生和腐生性病害有软腐病、红腐病、黑果病、曲霉病、灰霉病、红粉病。烂铃的虫害在前期(7月下旬～8月中旬)为二、三代玉米螟,在中后期(8月下旬～9月中旬)为红铃虫,而以玉米螟为害较重。烂铃发生的严重程度,1978、1980年烂铃率在10%以下,其它年份都在10～30%,严重的达40～60%。棉花烂铃病害发生的种类、发生程度、发生时期,因年际的气候、棉株生长、虫害发生以及防 During the decade from 1976 to 1985, the occurrence and control of the rotten cotton boll in Shanghai were systematically observed and studied, and the control strategies were also discussed. Shanghai cotton boll diseases are mainly parasitic diseases and anthracnose disease, angular leaf spot in individual years. Weak, parasitic and saprophytic diseases include soft rot, red rot, black fruit, aspergillosis, gray mold and powdery mildew. Pests of rotten bell pests were the second and third generations of Ostrinia furnacalis in the early period (from late July to mid-August), and were red bollworm in the late period (late August to mid-September), while the damage to corn borer was heavier. The severity of rotten boll occurred in 1978 and 1980 when the rate of rotten boll was below 10%. In other years, it was between 10 and 30% and the severity reached 40-60%.
