摘要
“早衰”是高粱生产和育种上存在的普遍现象。长期以来被认为是一种生理性病害。经4年研究证明它是草酸青霉(Penicilliem axalicum)和纤细交链孢霉(Allernaria allernala)于初花期浸染而引起的一种高粱穗部病害。主要症状是颖壳及与其连接的枝梗组织坏死,阻止了养分、水分向上输导,造成籽粒秕瘦变小。一般减产10％以上。这是国内首次报道的高粱新病害,定名为高粱青霉颖枯病,此病在初花期用多菌灵防治有较好效果。
Sorghum glume blight is a widely distributed disease in the sorghum growing areas of Shanxi province. The typical symptoms of the diseased plants are withered glumes and small seeds. 1984 to 1987, Penicillium spp. , Alternaria spp. , Curvularia spp. , and Fusarium spp. were isolated from diseased sorghum plants. It was proved that Penicillium oxalicum was the major causal agent and Alternaria alternata was the next. Good control results were obtained by spraying sorghum with the fungicide carbendazim at the early blooming stage.
