Clemson Plant Pathologist Tony Keinath has a new article featured in the American Vegetable Grower. Click here to read about “Why Disease Control is More Challenging on Leafy Greens.”
Don’t forget about the Watermelon Field Day coming up this Thursday (7/14) at the Edisto Research Center (64 Research Rd.) in Blackville from 8am-1pm. Registration opens at 8am and no RSVP is required.
Do you have a whopper melon on your farm right now? Bring your biggest melon to the EREC Watermelon Field Day on Thursday to compete in the first annual big watermelon contest. The grower with the biggest watermelon weighed in will receive a cash prize from the SC Watermelon Board and bragging rights for the 2022 growing season. Weigh-in will begin at 7:45 AM and run until 8:15 AM. The winner will be announced by the SC Watermelon Queen at the event. Good luck!

Coastal Region
Zack Snipes reports, “The recent rains have yet again made fields sloppy and hard to harvest. Most of our tomato crop is about finished as are zucchini and cukes. We have had an unusually high amount of southern stem blight in tomatoes this year. We are seeing some increased worm pressure (armyworms and fruitworms) in fields that are still producing. We have planted some acreage of fall watermelon and are getting other fields ready for the fall season. Many growers are painting black plastic white to reduce the heat held in the beds. If re-using spring drip tape and plastic, it is a good idea to flush irrigation lines and pulse irrigate beds with a liquid phosphorous product before planting your fall crop.”
Midlands
Justin Ballew reports, “We got more rain almost every evening last week. With the exception of a few low spots, most fields are still in a workable condition. This is one occasion when having sandy soil is a blessing. We’re entering an in-between stage where lots of spring-planted crops are finishing up and fields are being prepped for planting fall crops. Diseases have picked up some recently, though growers are doing a pretty good job of managing them. I’ve also seen an increase in false chinch bug populations recently. In most cases, they don’t cause a whole lot of direct feeding damage, but at high populations, the bugs themselves can become contaminates in harvested greens. Hopefully, they won’t stick around long.”
Sarah Scott reports, “We wanted rain and have gotten plenty! Significant rain events following a hot and dry period have brought up some issues in the peach field. Brown rot has been hit or miss this year, but in some areas, it is pretty bad with wet weather contributing to some spread. The “cooler” temperatures in the coming days along with wet weather will likely cause an explosion of the disease in orchards if not treated properly. Bronzing is another issue that we have started to see following rain events. Although it is unclear exactly what causes the skin discoloration, rain events following periods of dry weather do seem to increase the bronzing, especially on peaches that have darker skin and are closer to harvest. Spider mite populations have slowed down thanks to the rain, but they were pretty bad in recent weeks and some trees have significant leaf drop from heavy infestation. Scale crawlers are being seen in the orchards as well. According to our entomologist, Dr. Brett Blaauw, GA has not seen a significant peak in crawler populations so we are hoping we too will not see a heavy increase in SC. Monitoring for scale crawlers can be done by putting some black tape, sticky side out or covered with double-sided tape, on branches of peach trees in orchards known to have scale issues. The rain has made this a bit challenging but I have still been able to find crawlers when checking “traps” prior to rain events.”
Upstate
Andy Rollins reports, “Vegetable production is in full swing picking tomato, pepper, cucumber, squash, zucchini, sweet corn, and others. We have some minor problems with various caterpillar pests, some tomato wilt virus, and plenty of spider mites. We’re harvesting heirloom tomato varieties from retired tomato breeder Dr. Randy Gardner on 3 farms. Mountain Girl is doing better than others. We are having some blossom end rot everywhere, but it was only on a few of the first fruit before clearing up. The peach crop has improved quite a bit on some farms, but not others. We are seeing excellent eating quality on Scarletprince, Juneprince, and July Flame. We are picking a few Contender, Redglobe, and also Julyprince. We are concerned about heavy rains causing cracking on all crops.”
