Rob Last reports, “Pest and disease issues in the area remain very low; however, as temperatures rise, we expect activity to increase. Although it is quiet, it is still essential to continue to scout. Assessment of crops indicates that we have escaped the worst of any chill injury or loss of plants. Pruning of fruit crops continues while dormancy holds and labor begins to return to the area.”
Justin Ballew reports, “We had another cool week last week, and some places on the eastern side of Columbia saw a little bit more snow. Strawberries are progressing, and most fields now have 3 to 4 crowns. Some growers have been working on sanitizing cold-damaged blooms and fruit from the plants, and their fields are looking good. For those that haven’t started sanitizing yet, don’t forget to do this prior to growth taking off in the spring, or having all those dead blooms and fruit present will make disease management more difficult. Deer feeding damage seems to have picked up in the last couple of weeks. Fencing can still be helpful at this point in the season. The number of plants saved will quickly make up for the cost of the fence. Take a look atthis publication for fencing plans and costs.
Sarah Scott reports, “Peach pruning and tree planting is still going on here in the Ridge. This week a grower spotted some white peach scale on a single branch in his orchard. White peach scale usually isn’t widespread and isolates to one or just a couple of trees. It has been spotted more this winter than in the past, so growers should be on the lookout. Regular dormant oil applications should take care of the population or spot treat.”
Bruce McLean reports, “Winter is upon us, and it’s finally good pruning weather. Perennial fruit crops

Rob Last reports, “Strawberry crops continue to develop well with minimal pest and disease pressure so far. Fall vegetables are progressing towards the market. We continue to see pest pressure from caterpillars, and a few isolated aphids have been spotted during scouting. As we progress towards the holiday season, scouting of crops remains of vital importance to catch insect infestation and disease progression early for treatments to be effective.”
Rob Last reports, “Strawberry crops in the area are looking good with good crown development. We are seeing open flowers and some fruit set based on warmer conditions. These crops are cause for some concern as we are likely to see damage from forecast cold snaps. There is evidence of botrytis (gray mold) in crops on cold damaged flowers and fruit. Sanitation can really help to mitigate the spread of the disease. Spider mites remain active and in places are requiring treatment. Remember to avoid pyrethroids for mite control as these can flare mite populations.”
Happy New Year! We hope everyone had a great holiday season and is off to a good start in 2021. We have several virtual grower meetings coming up over the next two months, so keep an eye on the “Upcoming Events” page for info. Also, don’t forget the Southeastern Regional Fruit and Vegetable conference kicks off virtually this week, and it’s not too late to register.
Dr. Matt Cutulle reports, “Burndown herbicide efficacy can be reduced in colder weather, especially systemic products such as glyphosate (Reduced translocation in the cold means herbicide does not move through the plant as much).”
Rob Last reports, “Vegetable crops are growing out of the impacts of frost well. There is active Alternaria in places on brassica crops. Insect activity in vegetable crops in the area remains low. Strawberry crops are moving well, with a few spider mites and aphids being observed. Remember, if mite treatment is needed, use a specific miticide to target the pest to avoid flaring populations. If you need a second pair of eyes to help scout, then please give me a shout.”
Rob Last reports, “Crops in the area continue to develop well, and I expect this to continue after some welcome rainfall over the weekend. Following the rain over the weekend and returning to warm temperatures, keep scouting for diseases in crops and ensure fungicide applications are made promptly. Spider mites show activity in a range of crops from strawberries to peppers, tomatoes, and blackberries. Cucumber beetles are beginning to be found in sticky traps. Currently, no damage is being seen to crops.”
Rob Last reports, “In our area, crops are developing well with few pest or disease issues currently. Some brassicas are displaying a reddening to the older leaves associated with reduced phosphorous uptake. Phosphorous uptake can be reduced in cold temperatures but will recover when we see some warmer temperatures. There is no response to an additional application. Where strawberries are flowering or have fruit, it is advisable to remove those to minimize sources of Botrytis gray mold for later in the year.”
Zack Snipes reports, “It has been a very windy spring. The winds are drying out our soils and beating up plants. I have looked at some tomatoes, and the ones that aren’t tied are wind-whipped, and the ones that are tied have callus tissue forming where the string is touching them. We have some beautiful lettuce and greens coming in right now, along with spring onions. I have also seen some squash coming in on farms that grew squash in high tunnels. Strawberry plants are still small and have very few blooms for this time of year. We are harvesting highbush blueberries in high volumes right now. I think we escaped more cold damage than previously expected.”
Zack Snipes reports, “It seems like everything is coming in from the fields right now. We got some rain but could really use some more. I am seeing lots of aphids on a variety of crops (melons, cukes, eggplant). I am also seeing ladybird beetles and parasitized aphids in these fields, which means our predators are out there working for us. Bacterial wilt and Southern blight are starting to appear on tomatoes as well. Knowing the difference and preparing for next season’s crop is critical. It is getting hot and is still windy, so growers might consider adding one or more irrigation cycles to their fields. Remember that in our sandy soils, any irrigation event over an hour is just wasting water. More frequent 30-45 minute cycles are more efficient.”
