水稻紫鞘黄叶病(又称紫秆病、锈秆黄叶)在我省普遍发生。已知国内分布南至海南岛,北至大连。1978年我们首次以从病株上分离到的真菌,经人工培养后,于孕穗破口期喷孢子液接种水稻,获得成功;经我们与有关单位6季16次反复接种试验,证明此病主要是由头孢霉属真菌侵染引起的。现将有关此病的发生、为害及药剂防治结果整理如下。 Rice sheath sheath yellow leaf disease (also known as purple stalk disease, yellow leaf rust) occurred in our province. Known domestic distribution south to Hainan Island, north to Dalian. In 1978, for the first time, we isolated the fungi from the diseased plants and cultivated them to inoculate rice with the spore liquid at the booting stage of the bream. After repeated inoculation experiments with sixteen seasons, we found that the disease mainly Cephalosporium fungi caused by infection. Now the occurrence of the disease, damage and drug control results are summarized below.
