由植物病毒引起的植物叶斑病是常见病害之一。如烟草花叶病,甘蔗花叶病和番茄花叶病等。病毒侵染植物后即出现叶斑,影响光合作用正常进行,导致发育不良而减产和品质低劣。防治植物病毒性花叶病,多从杜绝侵染源消灭传毒媒介、选用抗病及耐病性品种、加强栽培管理措施等着手,同时逐步寻找药瓤治疗方法。据报道,日本千叶农业试验场研究室运用免疫学及交互保护作用原理,对病毒性花叶病进行了免疫处理,效果甚好,现已在生产上大面积推广。对大多数病毒来说,一个株系的侵染能抑制第二个和它密切相关
Plant leaf spot caused by plant viruses is one of the common diseases. Such as tobacco mosaic disease, sugarcane mosaic disease and tomato mosaic disease. Leaf spot appears after the virus infects plants, affecting the normal photosynthesis, leading to poor growth and yield and poor quality. Prevention and treatment of plant viral mosaic disease, and more from eliminating the source of infection to eliminate transmission media, the selection of disease-resistant and disease-resistant varieties, cultivation measures to strengthen management and so proceed, and gradually find the drug 瓤 treatment. According to reports, Japan’s Chiba Agricultural Experimental Field Laboratory using immunological and interactive protection principle, the viral mosaic disease immunization, the effect is very good, is now a large area in the promotion of production. For most viruses, infection of one strain inhibits the second closely related to it
