摘  要:
荔枝霜疫霉病是危害荔枝的重要病害,目前仍以化学防治为主。为探讨防治荔枝霜疫霉病杀菌剂的防治效果,进行五种不同杀菌剂防治荔枝霜疫霉病田间药效试验。试验结果表明,在荔枝挂果期喷药3次后,68.75%氟菌.霜霉威SE 600倍液、75%肟菌.戊唑醇WG 2500倍液、66.8%丙森.缬霉威WP 800倍液、70%丙森锌WP 500倍液和68%精甲霜.锰锌WG 800倍液5种不同处理对果实成熟期霜疫霉病的各自防效为89.92%、91.45、89.53、88.11、88.01,差异不显著,可在荔枝产区上轮换应用。

摘  要:
Litchi downy blight caused by Peronophythora litchii is a devastating disease of litchi plants in China,which is prevented and controlled mainly by chemicals at present.In order to explore the control effect of 5 germicides,an experiments was conducted and the results show that after being tested in the Litchi fruiting period for 3 times respectively,(68.75% fluorine bacteria with propamocarb SE using 1: 600,75% Trifloxystrobin with tebuconazole WG using 1: 2500,66.8% iprovalicarb with propineb WP using 1: 800,70% propineb WP using 1: 500 and 68% metalaxyl-M with mancozeb WG using 1: 800),the abrov-mentioned treatments' control effect in turn are 89.92%,91.45%,89.53%,88.11% and 88.01%,demonstrating that the control efficiency of the above 5 kinds of germicides are of little difference and they can be used by turns in the litchi producing area.
