摘要
[ Objective] The paper was to discuss the control effect of tomato and maize intereropping against tomato powdery mildew. [Method] Three tomato varieties （6629, .[in＇aihong and Yuxing） and two maize varieties were selected as materials, and control effects of maize and tomato intercmpping against tomato pow- dery mildew were studied in the paper. [ Result ] Tomato and maize intercmpping had obvious control effect against tomato powdery mildew. The relative control effect of 6629 was the highest （61.1%）, followed by Jin＇aihang （49.5%）, and the control effect of Yuxing was the lowest （30.4%）. [ Conclusion] The study provides the theoretical basis for pollution - free production of tomato.
