甘薯生产上的主要病害黑斑病(Ceratocystis fjmbrjataE11)近年来有所回升,北方广大地区用温床育苗,伏薯后由于种薯带病,易造成烂坑,生产上迫切要求简易的防病措施。1975年之后对苯骈咪唑类内吸杀菌剂应用于甘薯黑斑病的防治,进行了室内试验及生产防治试验,实践证明:多菌灵(MBC、CTR—6669)、7313及托布津(NF—44)等用于浸薯、浸秧、薯坑泼浇等均能高效的控制黑斑病,防效均高于生产上应用的药剂“401”及代森铵等,深受广大群众欢迎。
Ceratocystis fjmbrjataE11, a major disease in sweet potato production, has rebounded in recent years. In northern part of the world, seedlings are raised on hotbed. After potato is diseased due to potato disease, it is easy to cause bad pit. Therefore, it is urgent to produce simple disease prevention measures in production. After 1975, the antibacterial agents of benzodiazepines were applied to the control of sweetpotato black spot. The indoor experiments and production control tests were carried out. Carbendazim (MBC, CTR-6669), 7313 and Topaz -44) and so on for soaking potatoes, soaking seedlings, pouring pot and pit irrigation can effectively control the black spot disease, the control effect is higher than the production of pharmaceutical agents “401” and the generation of ammonium and so on, welcomed by the masses .
