What are the control methods for rapeseed viral disease?
How to control rapeseed viral disease? Please advise. Rapeseed viral disease symptoms occur in all rapeseed production areas nationwide, with especially severe incidence in the winter rapeseed areas of North China, Southwest China, and Central China. The symptoms of this disease vary slightly depending on the type of rapeseed. Brassica rapa and Brassica juncea mainly develop chlorosis along both sides of the leaf veins, with leaves showing a yellow-green mosaic pattern, and the veins appearing translucent; in severe cases, the leaves shrink, curl, or become deformed, and diseased plants are markedly stunted, mostly dying before or at the bolting stage. Plants with mild infection and late onset may still bolt, but the flowering stems are curved or stunted, flowers and pods are densely packed, pods are shrunken and thin, and maturity is advanced. Brassica napus, by contrast, develops systemic necrotic spots, with symptoms appearing early and conspicuously on old leaves, then spreading to newly emerged leaves. At the initial stage of infection, needle-tip-sized transparent spots appear, which later expand into nearly round 2-4 mm yellow spots with dark brown necrotic centers, and the necrotic spots are surrounded by an oil-soaked appearance. On the stems and bolts, purplish-black spindle-shaped to elongated lesions appear, spreading from the middle-lower part toward the branches and fruit stalks; in the later stage, the stem lesions mostly split longitudinally or transversely, and the flowers and pods tend to wilt or die. The pods develop black necrotic spots and are mostly deformed.
