辣椒病毒病是辣椒生产中的主要病害。近年来由于病毒病的为害,一般辣椒减产10％以上,不仅影响产量,还使品质下降。病毒病在辣椒各个生育阶段都可发生,而且随着气温的变化,病毒的增殖量逐渐加大,症状亦越趋于明显。引起辣椒病毒病的毒原主要有黄瓜花叶病毒(CMV)和烟草花叶病毒(TMV),我省以TMV占优势,CMV次之。田间症状主要有落叶、叶脉或茎杆变褐坏死,生长点萎蔫坏死、花叶、疱斑、蕨叶、丛枝、矮化、畸形果等。 Pepper virus disease is the main disease in pepper production. In recent years due to the damage of the virus disease, the general pepper yield reduction of 10% or more, not only affect the yield, but also to the quality decline. Virus disease can occur in all stages of pepper growth, and as the temperature changes, the proliferation of the virus gradually increased, the symptoms become more apparent. Chlamydophila virus (CMV) and tobacco mosaic virus (TMV) are the main causative agents of pepper virus disease. In our province, TMV is dominant and CMV is the second. Field symptoms are deciduous, veins or stalk browning necrosis, wilting necrosis, mosaic, blister, fern leaves, Congzhi, dwarf, deformed fruit and so on.
