“Fall soil samples collected after harvest (up to 6 weeks after the R8 growth stage) can be useful to monitor changes in [root-knot nematode] population densities or to make management decisions for the subsequent cropping season. Soil samples should be collected at an 8 to 10-inch (20 to 25-cm) soil depth within the root zone of the previously existing crop.”

Double trouble on zinnia: Alternaria blight causes circular spots w/t white centers on upper leaf surface. Powdery mildew causes white dusty spots on leaves, stem & flowers leading to yellowing & defoliation. Use Sanitation, tolerant varieties & proper watering @MSUDiagnostics

Do your bermuda greens have gorgeous roots but still look drought-stressed? It may be an insect problem. #Mealybugs are sap-sucking insects that settle down at the base of the plant and secrete a white waxy (looks powdery) coating over their 2mm long pinkish bodies. #MSUext

Spent the afternoon in the Delta with Dr. Kristy McAndrew’s lab looking at some stands of ash. Prolonged drought stress is taking a toll on a wide variety trees in this region of the state and is predisposing them to insect and disease problems. #MSUext

It’s parsley worm time! Every year I delight in sharing my parsley with the beautiful caterpillars that will become black swallowtail butterflies. They are voracious feeders, but the plants will recover. #MSUext

Although pasture mealybugs have not been detected in Mississippi, entomologists and forage specialists at Mississippi State University urge farmers to frequently scout their pastures for signs of the invasive pest.

Our newest research paper compares the efficacy of fluopyram (Indemnify) with cyclobutrifluram (Trefinti) for management of lance Nematode. Great work @EricaGuri !

They might not sting, but this invasive species can actually cause costly electrical problems.

Still seeing a lot of new fairy ring popping up on bermudagrass fairways across parts of the Southeast. I like Densicor or Kalida now as they also have activity against mini ring. Water in immediately. Wetting agents help!
