麦赤霉病的发生预测,过去主要是利用气象因子的方法,但仅用此法未必充分。为了提高麦赤霉病发生预测的精确度,作者对发病的主要原因病原菌子囊孢子飞散状况,自一九六○年起至一九六九年进行连续调查。结果表明,比以往利用气象因子的预测法精确度为高。调查方法:子囊孢子的捕捉,从四月一日至五月三十一日,采用明日山氏设计的孢子捕

Prediction of the occurrence of wheat scab belongs to meteorological factors in the past, but this method may not be sufficient. In order to improve the predictive accuracy of wheat head blight, the author conducted a continuous investigation on the scattering of ascosporogenous bacteria of the pathogen from 1960 to 1969. The results show that the forecasting method using meteorological factors has higher accuracy than ever before. Method of investigation: Ascospore capture, from April 1 to May 31, using tomorrow’s spore catch
