甜菜黑脚病病原、症状及药剂防治研究开始于五十年代末六十年代初。由于各地导致甜菜黑脚病的病原菌不同,药剂防治效果有明显差异,特别随着品种的更新,耕作水平的提高,农药长期使用带来的致病菌抗药性的产生,生态系微妙的变化以及环境因子的影响,黑脚病病原也发生相应的变化,造成药物的防治效果不稳定,黑脚病的发生为害仍很猖獗。笔者认为有必要对黑脚病病原、症状及药剂防治作进一步的研究,为防治提供理论依据。
Beet blackhead disease pathogens, symptoms and drug control research began in the late fifties and early sixties. Due to the different pathogenic bacteria causing sugarbeet black foot disease in various places, there are obvious differences in the control effect of the medicaments, especially with the update of cultivars, the improvement of farming level, the generation of pathogenic bacteria resistance caused by long-term use of pesticides, the subtle changes of ecosystems and Environmental factors, black foot disease pathogen also occur corresponding changes, resulting in the prevention and treatment of drug instability, black foot disease is still rampant damage. The author thinks it is necessary to further study the pathogens, symptoms and medicaments prevention and treatment of black foot disease and provide theoretical basis for prevention and treatment.
