调查在农民田和缅甸山州农业试验农场山区进行 ,根据病害测报评价定期用药、播期、烧堆措施在马铃薯晚疫病综合防治中的效果。试验 1的结果表明 ,在未施药的不同播期小区晚疫病严重 ,而施达克尼尔的小区病情明显轻。在试验 2中 ,Wallin’s测报系统准确地预测马铃薯晚疫病的初发生期 ,并建议开始施药。.降雨量 12 .7mm时施药比每周定期施药更有效。不同施药处理比不施药的对照增产 30 .1%～ 6 2 .2 %。病害造成的产量损失 2 3 1%～ 38 3%。烧堆措施对防治晚疫病无效 ,不过可增产 39.2 %。
The survey was conducted in the farmer fields and mountainous areas of Shan State agricultural experiment farm in Burma, and the effects of regular medication, sowing date and burning measures on the integrated prevention and control of potato late blight were evaluated according to the disease forecasting reports. The results of experiment 1 showed that the late blight was serious in different sowing times without applying pesticides, and the cell density of stachnone was obviously lighter. In Experiment 2, Wallin’s system of forecasting accurately predicted the initial stage of potato late blight and recommended start of application. Rainfall at 12.7mm is more effective than regular weekly doses. Compared with the non-application control, the yield of different application treatments increased by 30.1% ~ 62.2%. Diseases caused by the loss of production 2 3 1% ~ 38 3%. Burning measures for the control of late blight ineffective, but can increase 39.2%.
