Field Update – 11/11/19

Midlands

Justin Ballew reports, “The weather was a little cooler this week. The soil is cooling down also and is causing some purpling at the tips of the leaves of brassicas (a sign of phosphorus deficiency).  Roots have a hard time taking up nutrients in cold soil, so make sure your fertility is adequate. Caterpillar populations are still relatively low. We’re still seeing a few whiteflies, but their numbers seem a little lower this week also. Strawberries are looking great so far. We are about done with the fall crops.”

The soil Monday morning (11/11) was just under 50 degrees.  This will cause root growth and nutrient uptake to slow.  Photos from Justin Ballew

Sarah Scott reports, “There have been several nights where temperatures dipped into the low 30s and we have had a few frosty mornings along the Ridge. Pepper plants are beginning to come out and late summer/fall crops wrapping up. Broccoli continues to be harvested along with kale, spinach, sweet potatoes and collards. Peach growers are preparing their orchards for planting new trees.”

Pee Dee Region

Tony Melton reports, “Last week, I found Clubroot on collards in a home garden in Florence and the plant problem clinic confirmed.  This is clubroot an awful disease of brassicas (greens, cabbage, etc.).  It was first found in SC in 2015.  That farm has a voluntary quarantine to keep it from spreading.  Please do not move plants or soil and cause it to spread.  It will stay in the soil for a long time (almost forever) and has the capability to destroy the brassica industry in SC.  Brassica and sweet potato harvest are at full speed because of the possible cold damage this week.

Field Update – 11/4/19

Statewide

Dr. Matt Cutulle cautions growers to be careful with late planted greens. “If getting out late with greens planting I would be careful with applying treflan pre-plant herbicides, as cold soil temperatures can facilitate injury.”

Coastal Region

Zack Snipes reports, “We are finishing up with summer crop harvests of cucumber, squash, and beans and harvesting fall crops like broccoli, collards, root crops, and lettuces. The rains and, at times, cooler weather have helped our fall crops. This past week I found some really cool beneficial insects in our Lowcountry brassica fields.  When scouting take note of any beneficials in your fields and know that they are providing lots of pest control for you.  Black rot in brassica has started showing up pretty regularly with the recent rains and lower temperatures.  Crop rotation, using clean seed and transplants, and sanitation (removing of diseased tissue) can help with control of this disease.  Many farms are seeding cover crops this time of year. Cover crops like clover can be grown to increase soil biomass, produce nitrogen, suppress weeds, and provide nectar and pollen for our beneficial insects.”

Midlands

Justin Ballew reports, “We got some rain from thunderstorms last week and the weather has turned significantly cooler since. We are seeing a few spidermites on strawberries. Keep an eye out for those. We don’t normally see a lot spidermites this early, so don’t let them catch you not paying attention. Caterpillar populations are still low on brassicas and disease has been relatively low also. A few false chinch bugs have been reported on mustard and turnip. We’re cropping kale and collards and still picking some last minute fall squash, zucchini, peppers, eggplant, and tomatoes.”

Pee Dee Region

Tony Melton reports, “Bacterial leaf diseases of brassicas have been terrible this fall, maybe due to heat we had early  – processing greens had to be harvested early to meet grade.  I have found millions of  False Cinch Bugs on brassicas especially turnips – imidacloprid is a good control without killing beneficial insects.  Farmers (especially row crop farmers) need to be rotating from products containing chlorantraniliprole to other active ingredients – I have noticed a reduction of the length of control with these products.  Frost is here – protect.

Field Update – 10/28/19

Coastal Region

Zack Snipes reports, “Strawberries have been planted in the Lowcountry. Some rain throughout the week has really helped them take. Already seeing deer tracks in fields without fencing. I scouted a few fields and found enough juvenile spider mites to warrant a spray. We need to stay on top of the mites this season. Please scout your fields and take necessary measures to manage them.”

Midlands

Justin Ballew reports, “We had a few showers come through the midlands last week. Strawberry planting has wrapped up and the young transplants are getting established well so far, as we’ve had pretty favorable weather lately. Fall brassicas are looking great and worm pressure is still a little below average. Fall crops of cucumbers, tomatoes, peppers, green onions, eggplant, squash and zucchini are still being harvested.”

Pee Dee Region

Bruce McLean reports, “Brassica (cabbage, collards, turnips, broccoli, etc.) and strawberry planting has finished. The crops look very good. Okra and squash will finishing up soon. Downy mildew is still a challenge on squash. Brassica insect pressure has been relatively light, except for aphids which have been moderate in limited locations. Continue to scout regularly.”

Tony Melton reports seeing lots of worms and moths. “I have seen sweet potatoes stripped by stripped armyworms, armyworms, loopers and velvetbean caterpilars in greens, and millions of corn earworm moths in peas.  Also false chinch bugs are loving the turnips, kale, and mustard.  Strawberries are getting established. ”

Field Update – 10/21/19

Coastal Region

Zack Snipes reports, “A few rain showers and some cooler temperatures have really helped out our fall crops.  Collards, kale, and broccoli have really perked up this week and some early stuff could possibly be cut this week. Our worm pressure has not been terrible this year but that does not mean you can take a week off of scouting.  Strawberries have gone in throughout the Lowcountry and are looking great after some cooler temperatures and rain. If you have not put up your deer fencing for strawberries, get it out ASAP.  Each plant can be worth around $3, so one night of feeding can really cut into your bottom line.”

Midlands

Justin Ballew reports, “We got some much needed rain this past week thanks in part to Tropical Storm Nestor. This has our fall brassicas growing fast and looking great. We’re still seeing some whiteflies in brassicas, but the caterpillar numbers are a little lower for the time being.  Lots of strawberries were planted last week and they are developing well so far. The rain and cooler weather has really been helpful in getting them established. Strawberry planting will finish up this week for the folks planting larger acreages.”

Sarah Scott reports, “Cooler temperatures and much needed rain are giving a boost to fall crops including collards, cabbage and broccoli. Bell peppers, tomatoes, squash, broccoli, sweet potatoes are still being harvested as well as hemp. Strawberry plants have been going in over the past couple of weeks.

Pee Dee Region

Bruce McLean reports, “The recent rain from the remnants of Tropical Storm Nestor helped to improve dry soil conditions in the Pee Dee. This beneficial moisture should help the remaining cucurbit crops (yellow squash, zucchini, and cucumbers) and the okra crop through the final few weeks of the season. Planting of brassicas (collards, cabbage, kale, broccoli, etc.) and spinach are finished. Strawberry planting should be finished in the next week. Worm damage on brassicas has been light, but aphids have been plentiful in isolated locations. Be sure to scout your fall crops regularly.”

Tony Melton reports, “Still in the middle of harvesting processing sweet potatoes – not enough rain to size them up earlier, now having to wait for soil to dry and more rain is coming.  Bacterial disease on turnips bad this year (maybe because of the heat), losing about 1/3 of yield because we’re having to harvest early.  Also, reduced stand on greens from the beginning because of the excessive heat at planting.  Also, bacterial soft rot is bad in the heat where irrigation and harvest equipment has spread through the fields.  A lot of moths (Hawaiian webworm) flying in fields. We’re spraying once, which is more than usual (with Coragen and similar products) to keep larvae out of greens.  Last of the pickling cucumbers are being harvested this week.”

Upstate

 Mark Arena reports early harvest of pecans may begin soon. “Here are some tips for pecan management for the month of October. Prepare for harvest by mowing the orchard floor and keep it free of limbs and other debris. Maintain adequate soil moisture. Treat all “mouse ear” nickel deficiency noticed. Lime, zinc, phosphorus and magnesium can be applied if deficient. Scout and treat aphids, mites and pecan weevils as necessary. Apply preventative fungicides as scheduled and be aware of pre-harvest intervals for all chemicals applied.”

Field Update – 8/19/19

Coastal Region

Dr. Tony Keinath reports, “Phomopsis blight is showing up on eggplant at the Coastal REC. On susceptible cultivars, like ‘Black Beauty,’ the disease starts as leaf spots; later in the season stem cankers and fruit rot appear. Although several fungicides are registered on eggplant, none are specifically labeled for Phomopsis blight. Aprovia Top and Priaxor might give some control; more testing is needed before a definite recommendation can be made.”

Midlands

Justin Ballew reports, “Last week we had some scattered rains, but some areas remain bone dry.  Irrigation is running a lot in those areas.  Muscadine harvest has started and so far, this is the largest yield we’ve seen in recent years.  Squash, zucchini, eggplant, cucumbers, and tomatoes are also being harvested. Quality looks good, but volume is down a bit in some areas.  More fall brassicas are being planted and strawberry growers are just starting the process of prepping their fields.”

Pee Dee Region

Bruce McLean reports, “Much of the upper Pee Dee Region received beneficial rains late last week. This helped to drop temps back to about normal, following the excessive heat from a few days earlier. On most crops, the rain really helped to push production again. Late season cucumbers, squash, zucchini, and okra are looking good. Canary melons are looking excellent. Volumes on these crops are good. Last week’s heat did take a toll on watermelons, though. Volumes are significantly down from the prior week and are likely winding down for the season. Muscadines are a bit varied across the region. In some locations, ‘Carlos’ and ‘Noble’ (wine and juice varieties) are getting very close to harvest, while other vineyards are ripening a bit slower. Harvest on the most mature wine and juice muscadines could begin as soon as next week.

Tony Melton reports, “Heavy rain in certain area but none in others.  Some fresh market sweet potatoes are ready for harvest.  Processing sweet potato harvest will begin end of August.  Pickling cucumbers for machine harvest are still being planted most growers are favoring the parthenocarpic varieties.  Brassica planting has begun – seeds and transplants.  Fall bearing blackberries are yielding well.”

Upstate

Mark Arena reports seeing pecan scab. “Pecan Scab fungus is a weather dependant disease. There are varieties/cultivars that exhibit tolerance to this disease as shown below in the photos. Observed in Picture #1, we see both the nuts and foliage are showing signs of infection (the brown lessions). Picture #2 shows no sign of disease on either the nuts and/or foliage at the present time. Pecan scab can go undetected for days before the lessions appear, therefore, it is imperaitive to use a preventitive fungicide program to insure nut production.

Field Update – 5/6/19

Coastal: Zack Snipes reports, “Beautiful sunny weather has really pushed our spring crops this week.  We received some spotty thunderstorms this weekend that will help dryland crops as well as settle some dust.  We are approaching the end of strawberry season as berries are getting smaller.  Be sure to keep plants clean these next few weeks as berries develop quicker.  When berries develop quicker it is harder to keep them picked thus allowing pests such as spotted wing drosophila and botrytis to settle in.  We are seeing beautiful tomato, eggplant, and cucurbit crops growing off throughout the region.  We began squash and zucchini harvest this past week and are in the middle of highbush blueberry harvest.”

Midlands: Justin Ballew reports, “It was very sunny and warm last week. Storms came in Saturday afternoon and brought around 1.5 inches of rain. This was good for just about everything except for the strawberries. We are seeing a ton of water damage on berries now and grey mold has also picked up. Spider mite populations were building last week as well, so keep scouting for those. Spring and summer crops are looking great and growing fast. Stringing has started in tomatoes, heading brassicas are developing well, and leafy brassicas are being harvested daily.

Sarah Scott reports peach picking in the Ridge will begin this week with early varieties. “The season is on track for 2019 with a good crop load of early variety peaches. Bacteriosis is visible on some peaches once color begins to develop. Copper applications are critical to maintain best fruit quality. Refer to the 2019 Peach and Nectarine and Plum Pest Management and Culture Guide for recommendations.

Upstate: Kerrie Roach reports, “It’s been a great week for growers in the Upstate. Peaches are coming along nicely and apples are not far behind at about thumb size. Spring vegetables are in the ground with many producers projected to start picking squash in just a week or two. Farmers Markets have slowly started opening with mainly cool season crops. We are hoping for another great week of growing weather!”
