1978年我们在京郊调查7个公社15个大队的菜田,面积约500亩,发现菜豆枯萎病平均死秧率21.7%,个别地块,死秧率高达67%,严重影响产量。此病,远在1929年 Harter 和和1942年 Kendrick and Suyder 就有了报道,但国内研究不多。为此,我们对菜豆枯萎病发病规律的某些方面及防病措施进行了调查和试验。 In 1978, we investigated the vegetable fields of 15 groups of 7 communes in an area of ​​about 500 mu in the suburbs of Beijing. We found that the average dead seedling rate of bean fusarium wilt was 21.7%. In some plots, the rate of dead seedlings was as high as 67%, seriously affecting the yield. The disease, as far back as Harter in 1929 and Kendrick and Suyder in 1942, was reported but not much studied in the country. Therefore, we investigated and tested some aspects of the pathogenesis of Fusarium Wilt and disease prevention measures.
