金瓜贮藏期主要病害有炭疽病和湿腐病。炭疽病菌和湿腐病菌菌丝生长最适温度均为28℃;分生孢子萌发最适温度,炭疽菌为20~30℃,湿腐菌为25~35℃,分生孢子的致死温度,炭疽菌为52℃,湿腐菌为53℃。菌丝生长和孢子萌发最适宜pH值,炭疽菌分别为7~8和5~6,湿腐菌分别为8~10和4左右。以10%的寄主汁液最能刺激孢子萌发。化学药剂以多菌灵1000倍和噻菌灵1000倍对炭疽菌菌丝抑菌作用明显,施保功1000倍对湿腐菌菌丝有效。
The main diseases of gourd during storage are anthracnose and wet rot. The optimum temperature for the growth of mycelia of C. anthracnose and wet rot were 28 ℃. The optimum temperature for conidia germination was 20-30 ℃ for anthrax and 25-35 ℃ for wet rot fungi. The lethal temperature of conidia, anthrax 52 ℃ for bacteria and 53 ℃ for wet rot fungi. Mycelial growth and spore germination optimum pH value, anthrax were 7 to 8 and 5 to 6, wet rot fungi were 8 to 10 and 4, respectively. Spore germination was best stimulated by 10% host juice. Chemical agents with carbendazim 1000 times and thiabendazole 1000 times bacteriostatic effect of anthrax mycelia obvious, Shi Bao Gong 1000 times wet mycelium is effective.
