本研究对葡萄黑痘病发生的环境条件、品种抗病性及药剂防治等方面,进行了调查和试验,结果表明:地势高燥或排水良好,且除草、整枝及时,使园中湿度较低的,发病较轻;在品种方面:乍娜最易感病,巨峰中抗,红富士、先锋、早生高木、龙宝、康拜尔早等品种抗病力较强。药剂防治试验中50％果病灵和50％多菌灵的600倍液防治效果最好,防效达88.97％和81.86％;其次为灭黑灵、拌种双、速保利,防效分别为75.18％、58.36％和66.18％,但粉锈宁无效。此外还发现斑衣蜡蝉危害似有加重黑痘病的可能。
In this study, we investigated and tested the environmental conditions, disease resistance and chemical control of Anthurium andrutum. The results showed that high terrain or good drainage and timely weeding and pruning made the humidity in the garden lower , The incidence is less; in terms of varieties: Zachary most susceptible, Jufeng Zhongkai, Red Fuji, Pioneer, early Takagi, Longbao, Kang Baier early variety stronger resistance. Pharmacological control test 50% of the fruit and the spirit of 50% carbendazim 600 times the best control effect, control effect of 88.97% and 81.86%; followed by the black spirit, seed dressing double, Pauli, control effect was 75.18%, 58.36% and 66.18%, but triadimefon invalid. In addition, spotted wax cicada also found it possible to increase the risk of acne.
