Tobacco streak of soybean
Symptoms of Tobacco streak virus (TSV) include bud blight, shepherd's crooking, stunting, wilting, delayed maturity, bud and leaf proliferation, reduced pod number, and discolored, distorted, and dead leaves. TSV infection can cause discoloration and dead streaks at nodes, dark spots on pods, and delayed seed development.
TSV can be seed transmitted but is also spread by thrips. Hot, dry weather is conducive to disease development.
Make sure to plant disease-free, high-quality seed. Tobacco streak incidence may be decreased by delaying planting.
