Because of this cold weather and freeze last night, Sclerotinia sp. can be a problem in our cabbage, cauliflower, collards and other leafy brassicas. I would recommend 5-day rotation with following fungicides; (Fontelis ; at labeled rate) and (Endura; at labeled rate).

All behind the scenes indications are that the comment period for the pyrethroids risk assessment will be extended. However, it appears that this cannot be officially approved and completed under the current Executive Order that limits regulatory activity. The governmental web pages (including EPA’s) that were set up to accept comments show the comment period…

Nine are specifically being evaluated, but serve as surrogates for all 19 active ingredients. The preliminary evaluation shows that all pyrethroids exceed “Levels of Concern” for exposure to aquatic invertebrates. THIS IS MAJOR. If LOCs are exceeded,…

Cucurbit yellow stunt disorder virus (CYSDV) has recently been confirmed on cucumber and cantaloupe samples in GA. Symptoms: Initial symptom starts with chlorotic (yellow) spotting, which gradually develops into a distinct interveinal chlorosis (yellowing). The veins of the leaf remain green but the rest of the leaf turns bright yellow giving an appearance as that of a nutrient deficient leaf.…

Got a question today concerning mixing Coragen and Bravo with the Coragen targeting whiteflies. I do know from research plots that Coragen needs to be mixed with a penetrating surfactant when targeting whiteflies. If targeting caterpillars (which eat the surface of the leaf) this is not needed, but whiteflies feed inside the leaf and the…

Cucumber downy mildew has been reported from few counties in GA in Fall watermelon and cucumbers. This disease can cause severe defoliation and vine decline resulting in significant yield loss.
