Thrips (T.) parvispinus was recently observed in Florida on cucumber, squash and zucchini for the first time last spring. First symptoms look like broad mite damage, so growers need to scout for thrips.

Florida watermelons benefit from UF/IFAS research
Plant disease and water information from University of Florida Extension and researchers helped Florida watermelon farmers grow a bumper crop in 2023. Part of this year’s success came from partnerships between the industry and UF/IFAS research and Extension to provide information on disease management and extended water and nutrient programs, keeping the crops healthy and productive much longer than normal.

Preventitive sprays help hold Powdery Mildew at bay
For producers who are actively scouting for the disease, symptoms start as circular yellow areas on the leaves. As the infection progresses, growth of the fungus appears and can be observed on the underside of the leaves. “White powder” can be viewed on both surfaces of the leaves and stems as the tissue decays.
Florida Watermelon Producers Should Guard Against Powdery Mildew
Powdery mildew is different than most of the other major watermelon diseases in that it can become active under relatively dry conditions.

Caterpillar pressure has increased to moderate levels in Homestead, Florida, though beet armyworm was reportedly at high levels in okra. Rindworm damage was also reported from melonworms and pickworms in watermelon.
