综合防治是控制地瓜黑斑病为害的有效办法。用化学农药处理瓜种、瓜苗是综合防治措施中的重要一环。过去曾推广赛力散药剂处理瓜苗,取得一定效果,但有机汞剂停用以来,尚缺安全、高效的药剂代替。 1974年我所与荣成、牟平、栖霞等县部分生产大队结合,开展苯骈咪唑类新农药“7313”防治地瓜黑斑病的试验、示范工作。结果表明,“7313”对地瓜黑斑病有高效,浸种效果接近温汤处理,浸苗效果显著优于赛力散。
Integrated control is an effective way to control sweet potato black spot disease. With chemical pesticides to deal with melons, melon seedlings is an important part of comprehensive prevention and control measures. In the past, salerkal had been used to treat melon seedlings with some success. However, since the deactivation of the amalgam, there is still no safe and effective alternative medicine. In 1974, we cooperated with some production brigade units in Rongcheng, Muping, Qixia and other counties to carry out experiments and demonstration work on preventing and curing sweet potato black spot disease with the new pesticide “7313”. The results showed that “7313” was effective on sweetpotato black spot, and soaking effect was close to that of warm soup.
