Field Update – 6/1/20

Statewide

Dr. Matt Cutulle reports, “Yellow nutsedge is one of the more problematic weeds we deal with and we are approaching peak nutsedge season with the heat and all the rain we have been getting. Post herbicide options are limited in most vegetable crops. However, if growing sweet corn you may have the option to combine a good (Basagran) Post nutsedge herbicide with an average Post nutsedge herbicide (Callisto) to provide excellent control of yellow nutsedge. Please consult your seed company regarding whether a specific variety is expected to be tolerant to post-emergent applications. The majority of sweet corn is tolerant to PRE application of Callisto.”

Coastal

Zack Snipes reports, “We had some heavy rains in places last week, but everything seems to be drying out. It seems that every crop is coming in right now from basil to zucchini so everyone is busy out in the fields. Now is the time, when things are busy, that insects and diseases thrive. Perhaps a weekly fungicide application is skipped and a small issue turns into a disease or insect outbreak. Stay on your scouting, IPM, and spray programs as much as possible.”

Midlands

Justin Ballew reports, “Lots more rain last week, but the weekend was nice and allowed for a lot of the excess water to dry up. It doesn’t take long in our sandy soil. Lots of water damaged strawberries along with Botrytis and either Rhizopus or Mucor rot (possibly both). Some growers have wrapped up picking and others will be wrapping up soon. We’ve had a decent picking season here in the midlands and reported sales were very good. Other crops like tomatoes, peppers, sweet corn, and beans are growing fast and looking good. Stay on top of disease programs right now.”

Sarah Scott reports, “Peach harvest is going strong throughout the Ridge. Warmer, wet weather has been on the increase which could give way to some emerging pest and disease issues. Brown rot is showing up in some orchards. Bacterial spot is also heavy in areas. Continue spray programs following the Southeastern Peach,  Nectarine and Plum Pest Management Guide. Summer crops and looking good with some powdery mildew showing up in squash. Increased diamondback moth caterpillars in broccoli.”

Pee Dee

Bruce McLean reports, “Strawberry season has (for-the-most-part) come to an end. Heavy rains for the last two weeks was the primary reason. Excess moisture has damaged blueberries and caused a somewhat early harvest of potatoes. Many fields are too wet to make pesticide applications. Disease, insect, and weed pressure is getting rather heavy in spots. Fertility is a major concern, as well. Much of the pre-plant fertilizer applied early in the season is likely leached out/moved in the soil profile, and fields are too wet to apply fertilizer. Drier conditions are desperately needed to improve field and crop conditions.”

Tony Melton reports, “I am thinking about becoming an aquaculture agent to help farmers stock all these ponds from the rain in their fields. I am recommending folks to spray phosphide products to perk-up the crops and help with all the root rot – even if it has to be done with an airplane. Thrips, stink bugs, and false cinch bugs are awful this spring. We have Pythium growing in sweet potato transplant beds and on cucumbers from the heat and rain. Everything from cucumbers to peppers are baring early because of the stress of the wind earlier in the spring. We are adding extra nitrogen to everything because of the leaching rains. Weeds are taking over the world.”
