用50%安克WP(可湿性粉剂)、58%甲霜·锰锌WP、25%甲霜·霜霉WP、80%大生M-45WP和30%代森锰锌悬浮剂等5种杀菌剂防治荔枝霜疫霉病。结果表明:第4次药后第7天防效分别为80.8%、75.5%、76.6%、75.0%和67.7%;采收前防效分别为82.9%、75.7%、77.4%、75.3%和66.1%;采后贮藏第2天防效分别为68.6%、66.7%、67.5%、63.1%和57.9%;50%安克WP等5种药剂对荔枝霜疫霉病都有较好的防治效果,可在荔枝产区轮换使用。
Field experiments were conducted to control Peronophythora litchi Chen ex Ko et al with 5 fungicides. The control effects of Dimethomorph 50WP, Metalaxyl-Mancozeb 58WP, Metalaxyl-Propamocarb, 25WP Dithane M-45 (Mancozeb) 80WP and Mancozeb 30SC on P. litchi were observed to be 80.77%, 75.46%, 76.58%, 75.02% and 67.66% respectively at the 7^th days after the 4^th round of treatment, 82.90%, 75.68%, 77.37%, 75.30% and 66.06% respectively before harvest, and 68.64%, 66.67%, 67.46%, 63.07% and 57.89% respectively at the 2^nd day of storage after harvest. The results showed that these 5 fungicides provided good control against P. litchi, and can be applied alternately in litchi plantations.
