摘要
利用比利时CARAH预警系统指导分别施药4次,研究了8种药剂对马铃薯晚疫病的控制作用以及对马铃薯产量的影响,为防治马铃薯晚疫病提供科学依据。结果表明:0.3%丁子香酚SL对晚疫病的防治效果和马铃薯的增产效果最好,其他依次是52.5%恶唑菌酮.霜脲WDG、60%锰锌.氟吗啉WP、64%恶霜.锰锌WP、80%代森锰锌WP、50%烯酰吗啉WP、80%三乙膦酸铝WDG、35%甲霜灵WP,其中0.3%丁子香酚SL处理4次后对晚疫病的防效为80.25%,比对照增产达51.09%。0.3%丁子香酚SL作为生物药剂,兼有安全环保、持效期长等优点,可在马铃薯产区大面积推广应用。
The effects of eight fungicides against potato late blight and＇on the yield of potato were tested, with four times spraying under the guidance of Belgian CARAH warning system in order to provide an important theoretical base for the control of potato late blight. The results showed that Eugenol 0.3% SL had the best activity with 80.25% control and an increase in yield by 51.09% compared with the control, followed by Famoxadone ＋ Cymoxanil 52.5% WDG, Mancozeb ＋ Flumorph 60% WP, Oxadixyl ＋ Mancozeb 64% WP, Mancozeb 80% WP, Dimethomorph 50% WP, Triethyl aluminum phosphate 80% WDG, and Metalaxy135% WP. Eugenol 0.3% SL as the biological agent, with the advantages of safety, environment-friendly character and long duration, could be used extensively to control potato late blight in the field.
