摘要
[目的]针对广西河池市蔗区近年来甘蔗褐条病危害逐年加重的情况,筛选有效的防控药剂。[方法]以桂糖44号为对象,在河池市金城江区选用复合高效配方药剂40%苯甲·唑醚与常规杀菌剂进行叶面喷施田间药效对比试验。[结果]甘蔗褐条病对甘蔗长高、增粗、蔗糖分均产生较大的不利影响,最终造成甘蔗减产、减糖。8月甘蔗褐条病暴发前期,使用40%苯甲·唑醚药剂连续2次喷施可有效防治褐条病,见效快,防治效果持续时间长,防效稳定,比常规使用的50%多菌灵效果更好。[结论]建议重视甘蔗病害的防治,合理选用环保、高效的防病药剂,做好中后期甘蔗主要病害的科学有效防控,同时,还应注重抗病甘蔗品种的选育及推广应用。
[Objective]In view of the increasing harm of sugarcane brown stripe disease in recent years in Hechi city of Guangxi,effective prevention and control fungicides were screened.[Method]Taking Guitang 44as the research object,the field efficacy comparison test of foliar spraying with 40%benzoxazole·ether and conventional fungicides was carried out in Jinchengjiang district of Hechi city.[Result]Sugarcane brown stripe disease had a great adverse effect on sugarcane height,thickening and sucrose content,which eventually led to sugarcane yield reduction and sugar reduction.In the early stage of sugarcane brown stripe disease outbreak in August,the application of 40%benzodiazole·ether for two consecutive times could effectively control brown stripe disease,with rapid effect,long control duration and stable control effect,which was better than the conventional 50%carbendazim.[Conclusion]It is suggested to pay attention to the prevention and control of sugarcane diseases,reasonably select environmentally friendly and efficient disease prevention agents,and do a good job in the scientific and effective prevention and control of major sugarcane diseases in the middle and later stage.Meanwhile,it should also pay attention to the breeding,popularization and application of disease resistant sugarcane varieties.
