谷子锈病盛发期发生在谷子灌浆时期,谷子生育期后期低温多雨锈病易流行,谷子穗重千粒重与病指呈显著的负相关;谷子秕谷率与病指呈显著的正相关防治谷子锈病以70％代森锰锌每亩次120克,防治两次效果最好为77％。一、谷子锈病田间消长规律谷子锈病田间消长分始发期、缓慢增长期和盛发期。始发期发生在谷子抽穗以前,只有零星病株 Mildew rust occurred in the filling period of millet filling period, late mildew mildew cold weather prone to epidemic, millet spike weight and grain weight was significantly negative correlation; millet millet rate and the pathological index was significantly positive control of millet rust 70% Mancozeb 120 grams per acre, the best prevention and treatment twice as 77%. First, the law of the growth and decline of millet rust Millet rust growth and decline of the field of origin, slow growth and Shengfa period. The onset occurred in the millet before heading, only sporadic disease
