大豆胞囊线虫病(soybean cyst nematode,SCN),又称大豆黄萎病、火龙秧子,是制约大豆生产的重要病害,防治极为困难,严重影响农民收入[1]。防治该病最经济安全的措施是种植抗线虫品种,但由于常规育种工作所需周期较长,且由于选择压力存在长期种植抗病品种会导致品种抗性丧失。近年来,人们已将防治大豆胞囊线虫病的工作重点转向了生物防治。本研究通过对2年田间试验筛选出来的10株生防菌株进行复筛和防治效果评价,以期为大豆胞
Soybean cyst nematode (SCN), also known as Soybean Verticillium wilt, fire dragon seedlings, is an important disease that restricts soybean production, prevention and control is extremely difficult, seriously affecting the income of farmers [1]. The most economical and safe way to control the disease is to plant nematode species. However, due to the long period needed for routine breeding and the long-term planting of resistant varieties due to selective stress, the resistance will be lost. In recent years, people have shifted the focus of their efforts on the prevention and treatment of soybean cyst nematode disease to biological control. In this study, 10 strains of biocontrol strains screened from 2 years of field trials were screened and their control effects were evaluated.
