Watermelon (Citrullus lanatus (Thumb.) Matsum. & Nakai), including seeded (diploid) and seedless (triploid) varieties. No other cucurbit species are affected.
Fruits and Vegetables
Plants infected with race 2 of Fusarium oxysporum f.sp. niveum may die before producing fruit or be severely stunted, resulting in lower yields. No varieties of watermelon are resistant to race 2 of Fusarium oxysporum f.sp. niveum, so all watermelon production in Indiana is potentially threatened
Race 2 of Fusarium oxysporum f.sp. niveum has been confirmed in Knox and Gibson Counties and may exist in additional counties. There exists the potential for Fusarium oxysporum f.sp. niveum race 2 to spread from these counties to other watermelon production areas within Indiana. Race 2 may also be imported into Indiana via seeds or transplants.
