Field Update – 7/1/19

Coastal Region

Zack Snipes reports, “Everyone is busy in the Low country harvesting summer crops.  This should be a big week for us in the field and at local markets and roadside stands as July 4 approaches.  The tomato crop is either finished or finishing up this week.”

Midlands

Justin Ballew reports, “It’s getting hot here in the midlands and it’s getting dry too.  Harvest is still going strong on a number of crops.  We have a reduced blueberry crop because of the hot, dry weather back in May, but picking is going on now. Lots of hemp has been planted in the last two weeks and is growing well.”

Sarah Scott reports, “We are picking several summer varieties of peaches along the Ridge, many varieties coming in early. Freestone peaches are beginning to ripen and become available. A second population of Brown Marmorated Stink Bugs is near its peak based on high numbers found in traps across the Ridge. Be on the lookout for egg masses, generally in groups of 28 eggs. (picture) BMSB damage from earlier populations causes distortion as fruit ripens. Damage goes beyond skin into flesh.

Pee Dee Region

Bruce McLean reports, “Harvest for many vegetable crops are rolling right along. Watermelons and cantaloupes are starting to see some volume.  Early season rabbiteye blueberries are starting to wrap up. Mid and late season rabbiteyes are looking good. Heat and dry weather is starting to have an impact on crops, even those with irrigation. Growers are adjusting irrigation schedules to compensate for the increased heat and the lack of rain.”

Tony Melton reports, “Downy Mildew is showing up in later planted cantaloupes, cucumbers, and squash.  First planting of cantaloupes and watermelons are winding down.  Processing peas are drying and will be terminated soon for harvest.  Butterbeans that reset pods after heat at the beginning of June will begin harvest this week.  Sweet potato planting is winding down many of the first planted are laid-by.  Pepper and eggplant harvest has begun.”

Some Pesticides Now Approved for Hemp Production in SC

Yesterday (6/27/19) Clemson’s Department of Pesticide Regulation (DPR) released a list of pesticides they are now allowing for use in hemp production.  A PDF including a letter from DPR and the list of approved products can be accessed here: Approved Hemp Pesticides.  Please read the letter from DPR before using any chemicals on the list.  Additionally, it is recommended that growers speak with their processors to ensure using these chemicals will not result in any unacceptable residues.

Growers will now have some chemical options for treating insect and disease pests in hemp crops.

Previously, growers were only allowed 25(b) products, which the EPA deems “minimum risk products”. These are products that do not have EPA registration numbers (mostly plant extract oils).
