Crop Rotation Can Suppress Verticillium Wilt on Chinese Cabbage and Analysis of Factors Affecting Disease Development

Abstract

Abstract In this study, we examined the effect of crop rotation on the suppression of Verticillium wilt in Chinese cabbage. Compared to leaving cultivation areas fallow (i.e., no rotation), introducing crop rotations with broccoli or cabbage were significantly more effective in controlling this disease. Here we used a generalized linear model to evaluate the effectiveness of crop rotations in all trials. In addition, an optimal model was constructed using Akaike’s Information Criterion to select explanatory variables associated with disease suppression. In the best model, the estimated coefficients for crop rotation with broccoli and cabbage were − 0.56 and − 0.38, respectively, compared to fallow (p < 0.05). In addition, we found that susceptibility to disease varied by harvest month and year. This study shows that Chinese cabbage wilt can be controlled by crop rotation. Furthermore, the analysis of factors involved in the development of this disease can help cultivators eliminate it from Chinese cabbage production in the future.
