Quiet Insect Activity: Alabama Producers Still Need to Take Precautions
Insect pressure is currently quiet in Alabama. But infestations could increase dramatically if producers don’t take the proper precautions, says Ayanava Majumdar, Extension Professor in Entomology and Plant Pathology at Auburn University. “At this point, things are kind of calm and quiet, except perhaps for people who have greenhouse crops or are trying to start their seedlings or trying to …
Whitefly Management: Don’t Get Behind in Spray Program
Insecticides are available for growers managing whitefly populations. But they need to be applied early in the season when whiteflies are young and immature. “Most of the things we use primarily target immatures. That’s where our best control is.

Identification Key in Managing Stink Bugs in Tomatoes
Stink bugs are a diverse species that can wreak havoc on Florida’s tomato crop. With a piercing-sucking mouthpart, stink bugs pierce the fruit and suck out fluids.

Winter Weather Conditions Challenging for Alabama Vegetable Producers
A cold and rainy winter has been challenging so far for Alabama vegetable producers. Joe Kemble, Alabama Extension vegetable specialist, cautions growers that though it may be chillier, that does not eliminate certain diseases that can be problematic. “I will say on the vegetable side, things are a bit slow. Weather’s been not exactly ideal. The rainfall we’ve been having, …
Whitefly Management: Sanitation Key Especially for Watermelon Producers
Stormy Sparks’ message regarding whitefly management remains the same: If you’re done with the crop, get rid of that crop. Sanitation remains the best defense against whitefly buildup in Southeast vegetable and cotton crops.
