Coastal Region

Zack Snipes reports, “We are in the middle of muscadine and scuppernong harvest right now. Okra and mixed peppers are still pushing out despite the heat. We had a great Strawberry Production Meeting in Charleston last week. If you have any questions on strawberry production now is the time to ask before planting.”

Midlands

Justin Ballew reports, “We had a storm come through Saturday night that brought a little rain to some parts of the midlands, but overall we are still quite dry. More fall brassicas are going in the ground and there is already some caterpillar pressure on those that are up. Downy mildew is showing up on cucumbers and pumpkins on a more widespread scale now. Stick to fungicide programs if you’re growing fall cucurbits.”

Sarah Scott reports, “We have had hot and dry conditions along the Ridge with hit and miss showers. Running irrigation heavily. Late cherry tomatoes, eggplant, peppers and broccoli are being planted. Leaf footed bugs on late season tomatoes causing minimal damage. Peaches still producing through late August, possibly into early September. Field work is still being done to prepare for fall planting of new orchards.”

Upstate

Mark Arena reports fall webworms and tent caterpillars are showing up on pecans. “This is truly a nuisance pest and generally does not influence nut production. Proper control may be challenging since the webbing should be broken apart prior to spraying. Once the webbing is broken apart, the insecticide can make contact with the caterpillars and offer effective control. Any insecticides labeled for caterpillars will work.”

Pee Dee Region

Bruce McLean reports, “Temps have been soaring and rain has been scarce across the Pee Dee Region. Most crops are looking good though. Watermelon, cantaloupe, canary melons, cucumber, zucchini and yellow squash volumes are still up and quality is good. Okra volumes are really starting to pick up and the quality is very good. Okra is flowering heavy, so volumes should be good for the foreseeable future. Muscadines are continuing to ripen. Muscadine brix levels (sugars) are rather high for this time of the season. Harvest should be very good this year. Fresh market muscadines should be available starting this week.

Tony Melton reports, “Fall pickling cucumbers are being planted. Pythium is still prevalent on pickling cucumbers and may need to be controlled. Fall peas and snap-beans are up and growing and need thrips control, but I have found thrips are in low numbers this fall and they may grow out of damage. I have found some beet armyworms on peas in some locations – scout. Also, lesser cornstalk borers are bad on both peas and snap-beans mainly due to the dry conditions; therefore, irrigate if possible or apply Coragen or similar systemic product. Loopers are present on sweet potatoes but doing mostly very little economic damage. I have found some striped armyworms in certain locations which need to be controlled. Starting to plant fall processing greens.

Coastal Region

Zack Snipes reports, “Summer cover crops are looking good in the Lowcountry. Cowpeas are one of my favorite cover crops for their ability to shade out weeds, particularly nutsedge, and provide the land with nitrogen for the next crop planted. We have had some timely rains to keep everything green and prepare fields for the fall. Some fields are being laid out and prepared for the fall season now. One technique used for weed management is called the stale bed technique. This involves working the soil and bedding up a few weeks to a month before growers plan to transplant. An herbicide or a flame is used once weeds germinate on the bed tops. This process is repeated 1-3 more times before the crop is planted. Because the soil is not disturbed after the initial bedding process, weeds are less likely to germinate once a crop is seeded or transplanted.”

Midlands

Justin Ballew reports, “We had a few isolated showers throughout the week, but overall we’re still pretty dry in the midlands. Muscadines are ripening and some of the earliest varieties should be ready to pick this week. The first of the fall brassicas are up and growing now. Fall tomato, eggplant, and peppers are looking good. We are seeing some spidermites in tomatoes, so scout closely. If treatments are needed, remember to use high spray volumes to get good coverage and rotate IRAC groups.”

Muscadines are ripening and will be ready to pick very soon. Photo from Justin Ballew.

Lalo Toledo reports, “Fall bell peppers and Broccoli are being planted. We are continuing to pick string beans, processing tomatoes, and cucumbers. Field preparations are underway for fall planting for Brassicas. We finally got some rain over the weekend, which will help with the new plantings.

Upstate

Mark Arena reports, “Fall webworm or tent caterpillars are showing up on pecans. Breaking the web apart and spraying with an appropriate insecticide is an option.”

Kerrie Roach reports, “Peaches are still coming in strong in the mountains, and the apples are continuing to build. The earliest ‘Ginger Gold’ apples (right photo) are just about finished. ‘Golden Supremes’ (left photo) are still a little low on the sugar (Brix) scale, but will sweeten up a little more this week. We should be picking ‘Galas’ within the next two weeks if the weather cooperates.”

Pee Dee Region

Bruce McLean reports, “Well, it’s starting to look a bit like harvest time for muscadines. We’re seeing some advanced ripening this year due to heat, primarily in Carlos. There’s still some ripening to do, but it won’t be long. The crop looks really good this year… just a bit early. Watermelons, cantaloupe, yellow squash, zucchini, cucumbers and okra are being harvested in good volumes, and grading out well.

Coastal Region

Zack Snipes reports, “We are harvesting the last remaining things in the fields, preparing fields for fall planting, and planting fall pepper and tomato. I found an interesting disease in watermelon this week that is known as bacterial rind necrosis. While it is not entirely known what factors and pathogens cause the disease, it is thought that environmental conditions could increase the presence of this disease. If you have seen this disease, take precaution by rotating fields, staying away from varieties known to have had symptoms in the past, and stay on top of irrigation and nutrient management. I have also seen some spongy squash this week. The combination of heat, high humidity, and poor pollination can all lead to poor quality squash.”

Midlands

Justin Ballew reports, “The weather cooled down a few degrees towards the end of last week and felt nice. Fall tomatoes, peppers, and eggplant are in the ground now. Downy mildew was found in the midlands in slicing cucumbers this past week, so folks growing fall cucurbits definitely need to maintain a good spray schedule. Also, late last week, bacterial wilt was confirmed for the first time in hemp. In the future, growers will need to practice good rotation between hemp, tobacco, tomatoes, peppers, and eggplant.”

Lalo Toledo reports, “Bell peppers are being planted in Orangeburg and Clarendon counties. Hemp is growing well and is expected to make a good harvest. Worm damage was found on some hemp plants in Orangeburg county. Collards are also being planted. Mole crickets have been found tunneling in many collard fields.

Pee Dee Region

Bruce McLean reports, “Last week was a welcomed reprieve from the heat and humidity. Many crops seemed to respond positively from the temperature break, as well. Watermelon, cantaloupe volumes looked very good. Yellow squash, zucchini and cucumbers were well improved from the week before. Okra volume is on the rise, and should be coming off very well in a week or so. Peas and butterbeans, on the other hand, sustained significant damage from the heat and many plantings have dried up. The first of the week looks pretty dry with building temps. By the end of the week, some welcomed rain should be in the forecast.”

Zucchini are doing well in the slightly lower temperatures. Photo from Bruce McLean.

Midlands

Justin Ballew reports, “It was another fairly hot week with scattered afternoon showers. We’re about finished with the spring cucurbit and brassica crops and growers are planting some fall brassicas now. Peas, green onions, tomatoes, peppers and some eggplant are being picked now. Still seeing some cutworm damage showing up in hemp. They feed at night, so growers having trouble with cutworms may benefit from night time applications of Dipel or Grandevo directed at the base of the plant.

Sarah Scott reports, “The fall crop of bell peppers are being planted. We are continuing to pick peaches and have started picking Asian pears. Field prep is underway for fall planting of new peach trees. Old orchards are pushed up and the trees burned when they are no longer productive, making way for new orchards for the coming seasons.

Lalo Toledo reports, “Tomatoes have been suffering from many pest and diseases. Most prevalent Southern Blight (White Mold) and Bacterial wilt. Make sure to properly diagnose your pest and/or diseases. Improper identification has led to improper control.”

Pee Dee Region

Bruce McLean reports, “This last week’s hot weather has taken a bit of a toll on some crops in the Pee Dee Region. Volumes on cantaloupe, cucumber and peppers were off a bit due to heat related damage. But, cooler weather looks to be in the forecast for this upcoming week. Be on the look out for Downy Mildew in cucurbits. I found some in a field of cucumbers last week. Some fall crops have been planted. The remaining acreage will likely be planted after the temperature break.

Upstate

Kerrie Roach reports, “Many upstate apple growers are having to do some late thinning on orchards hit by hail from one of the many late afternoon summer storms. Picking early varieties like ‘Wolf River’ and some of the Golden Delicious sports. Peaches are in full swing as are all our major summer vegetable crops. As in other areas of the state we have seen many instances of southern stem blight on tomatoes.”

Coastal Region

Zack Snipes reports, “Most crops are finished here in the Lowcountry. There are a few crops that are being harvested for the final time this week. Fall watermelon and tomato are in the ground already. I saw some interesting cucumber beetle larvae damage on watermelons this past week. This type of damage will result in loads of melons being rejected by buyers. Crop rotation is a vital component to managing this pest. If you have seen this type of damage, please reach out so we can develop a plan of attack for next season. I attended the Edisto REC Watermelon Field Day this past week and learned about the future of robotics in agricultural production and had the opportunity to taste over 30 varieties of watermelons.

Midlands

Justin Ballew reports, “We had some scattered rain over the last week. Some folks are still needing some. We’re winding down on the spring brassicas and cucurbits. This is good because foliar diseases like anthracnose and powdery mildew are really increasing with the humidity. We’re still picking tomatoes and have started picking peas. Spider mites are picking up, so scout closely for those. Hemp is growing well, though we’ve seen some seedling disease and cutworm damage in spots.”

Sarah Scott reports, “Hot and dry weather along the Ridge. Conditions have been favorable for increased spider mite and stink bug activity.

Upstate

Andy Rollins reports seeing some blackberry tips wilting from raspberry cane borers. “If you see this, they need to be cut off 6 inches below the 2 girdled lines you see below. This material can be composted or you can just squish them. Insecticide sprays can be helpful but only when applied before symptoms appear. It is a type of beetle larvae that is feeding on the stem before becoming an adult. Commercially, there would have to be a major infestation to warrant the extra labor. Normally this won’t be present in a regularly sprayed crop.”

Pee Dee

Bruce Mclean reports, “Well, it looks like another hot week is on tap for us this week. Squash, watermelons, cucumbers, cantaloupes, peas and peppers are coming off in good volumes. Quality looks especially good on these crops. Blueberries and sweet corn are finishing up. Starting to see some disease in muscadines. If you are seeing leaf spots in them, it may be time to evaluate and adjust your spray program. Also, starting to see early ripening of fruit. Be on the look out for fruit rot.

Tony Melton reports, “Cucumbers having hard time setting fruit in the heat – getting many nubbins (crooked fruit). Parthenocarpic varieties seem to handle the heat better than regular pollinated varieties. Processing tomato harvest is progressing quickly and about ½ complete. Processing pea harvest will begin this week – thousands of acres ahead to harvest. Processing hot pepper harvest has begun and will continue for a month.

Coastal Region

Zack Snipes reports, “It’s hot in the Lowcountry! We are just about finished on all summer crops. Bell peppers and rabbiteye blueberries should finish up this week. We are still picking some okra and hot peppers. Keep an eye out for worms in the coming weeks. I am seeing some basil downy mildew on basil. I have seen lots of ant and cricket damage on recently planted hemp.”

Midlands

Justin Ballew reports, “It’s been hot and humid. Some lucky folks have gotten some isolated showers, but overall, we need rain badly. The humidity is allowing powdery mildew to pick up on cucurbits and pickleworms are showing up heavy in some fields. Hemp is doing well so far. We are seeing some mite, caterpillar, and cutworm activity.”

Pee Dee Region

Bruce McLean reports, “The recent rain showers have really helped the area crops. Cantaloupe and watermelons are seeing some good volumes coming out of the field. Mid season cucumbers are looking good as well. A consistent volume of peas are being picked and looking great. Sweet corn volumes are starting to fall off as the season is winding down. Muscadines are starting to size pretty well, and are looking very good.”

Tony Melton reports, “Butterbean harvest will be in full swing this week and it seems this week and next maybe our total spring harvest. Processing peas will begin harvest this week if rains hold off. Processing peppers are being harvested and will continue for next 4 weeks. Also, processing tomatoes are being harvested and will continue for 4 weeks. Harvest of second planting of pickles for processing will begin this week. Last of the collards for processing will be harvested this week.”

Upstate

Kerrie Roach reports, “In apple news, we are about 2 weeks from picking the early golden varieties and about 4 weeks out from Galas. Hail damage is wreaking havoc at many orchards, and we are hoping for some clear weather for a few weeks to finish out the prime growing season. Peaches have finally come in and are looking good right now. Later varieties of peaches at many orchards in the upstate are seeing between a 70-80 percent crop loss.”

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.”

Midlands

Justin Ballew reports, “We had a few storms last week that brought rain to most of the midlands. Everything is growing well and we are really benefiting from the timely rain and mild temperatures. Growers are harvesting collards, kale, cucumbers, squash, zucchini, herbs, tomatoes, peppers, and sweet corn.”

Sarah Scott reports, “Potatoes are being dug around Aiken. Conditions have been favorable for blackberry leaf rust. Plants that are affected will show small orange colored spots, or pustules on the undersides of leaves and on shoots. Pustules can appear on undersides of leaves as well. In severe cases defoliation can occur and a lack of vigor in canes. Refer the Small Fruit Consortium website for information on control and management.”

Pee Dee Region

Tony Melton reports, “Tomatoes are ripening. Sweet potatoes are mostly planted and lay-by has begun. Some peas are ready for harvest and the last of the collards are being harvested.”

Upstate

Andy Rollins reports, “Orange isn’t a good color to be seeing in your blackberry plants! Be on the look-out for leaf rust in Blackberry and get it properly identified. Over the last 2 weeks I have found this on 3 farms in the upstate and one in the midlands with another agent. This light orange colored leaf rust isn’t as destructive as the orange rust that can be found in the early spring on the ‘Navaho’ variety especially but it does deserve your attention. Spores can be found on the top and bottom of leaves so look closely sometimes it’s hard to see. There is a another leaf rust that has yellow colored spores. If you are still picking fruit, Rally or a generic product containing the same active ingredient ‘myclobutanil’ can be used but as always read and follow the label. Tilt (propiconazole) is labeled also but has a 30 day PHI. So, I would use Rally then follow with Tilt when I was finished picking. Hopefully this will help keep your blackberry patches clean. There maybe other options for organic growers also but I am not sure how effective they would be. NARBA (North American Raspberry and Blackberry Association) has a good article on this here https://www.raspberryblackberry.com/is-it-blackberry-leaf-rust-or-orange-rust/ .
