Many pests feed on squash from seedling to harvest. They are generally broken down into two groups: the chewing insects and the sucking insects. Chewing insects of squash consist of common pests like cucumber beetle, squash vine borer larva and pickleworm. Sucking insect pests consist of aphids, squash bugs and whiteflies. The pests a squash grower experiences may depend on location.
PREVENTION STRATEGIES
Remember that prevention of pests is the No. 1 goal of organic integrated pest management (IPM) systems. Rapid control after pest establishment becomes a difficult aim later in the production season. Cultural control tactics that include selecting virus-resistant varieties, timely planting and harvest (reduces pickleworm buildup), crop rotation and timely removal of crop debris after harvest (reduces squash vine borer buildup), consistent irrigation and trap cropping are some basic preventive approaches, also called Level 1 control.
Perimeter trap cropping with Baby Blue and New England Hubbard squash in a mixed system is effective in reducing cucumber beetle and squash bug damage to yellow squash (main crop).
PEST EXCLUSION FABRIC
For Level 2 control, growers should use temporary or permanent pest exclusion fabric to create a barrier between insect pests and the main crop. Two lightweight materials tested in Alabama include the Super-Lite Insect Barrier (Gardens Alive, Inc.) and AgroFabric Pro 19 (Seven Springs Farm, Inc.). Both these materials look like lighter versions of the common row cover used for frost protection, but these materials are much lighter with 85 to 95 percent light and rain penetration.
The trick is to put these light fabrics on low hoops (inverted loops) almost immediately after transplanting or after the seeds have germinated. These materials deflect much of the aphids and squash vine borers that fly early in the season. Squash plants can be grown inside the fabric for several weeks and removed or partially opened when flowering begins. Growers can also release beneficial insects like lacewings and lady beetles under the fabric for controlling accidental pest infestations.
Growers also have a wide range of organic insecticides to choose from (Level 3 control). See the Organic Materials Review Institute website (www.omri.org) to find hundreds of approved organic products.
Remember to scout squash crops for timely pest detection and identification, then use insecticides per the label with equipment that gives good coverage. For example, highly mobile squash bug adults are difficult to control with natural pyrethrin and spinosad, but the flightless small nymphs are far better targets for organic spray applications.
Several premix insecticides are available commercially today in a variety of packaging, making them affordable for farmers. Squash vine borer and pickleworm larvae are internal pests, which are difficult to manage with topical spray applications. Initiate timely sprays with targeted placement where insect pests are hidden.
Don’t quit spraying too soon since weather patterns can reduce insecticide persistence. Always spray in the evening hours when bees are not around and so that the solution can dry out overnight. Stop spray applications of organic materials when pests become inactive. You can save on the cost of insecticides and protect natural enemies this way.
Finally, it is recommended that growers get in touch with Extension personnel in their state to develop an IPM strategy suitable for their farm. Producers in Alabama can download the Farming Basics mobile app to keep in touch with Alabama Extension.

We are now exporting more fruit from the United States than we were last year. According to a story from Gary Crawford, we are also importing much less fruit.
LAKE ALFRED, Fla. — If information is power, Florida citrus growers have a new asset in their fight against citrus greening disease which has been impacting the state’s multi-billion dollar citrus industry.
The University of Florida Institute of Food and Agricultural Sciences statewide citrus program launched a major revision of a website, providing instant access to a portfolio of information valuable to growers.
The citrusresearch.ifas.ufl.edu website underwent a major revision, making it easier to navigate, adding new access to research trials, publications and presentations.
“We know growers are busy and don’t have time to search multiple sites for information,” said Michael Rogers, professor and director of the UF/IFAS Citrus Research and Education Center in Lake Alfred, Florida. “We put the most current research in one website where growers can search for and find what they need to be successful in today’s challenging growing situation.”
The new site includes special features of interest to growers including:
Data from over 20 rootstock trials conducted by the UF/IFAS plant improvement team. Growers can review the data collected from the trials and compare data from sites across the state.
UF/IFAS researchers share their ongoing research priorities in citrus economics, grove management, new varieties, nutrition/water management, psyllid management and root health.
A resources section includes current production and nutrition guides and Extension documents (edis.ifas.ufl.edu) on citrus-related topics from 2016 to the present that are easily linked to from the website and are also presented by researcher for easy searching.
“This website is just one of the ways that the UF/IFAS citrus team is working to support growers with the latest science to best battle citrus greening. We are working to get this information directly to growers as soon as it is available so that they may be able to put it into action as soon as possible,” Rogers said.
According to a University of Florida/IFAS blog, the corn earworm is especially concerning to corn and tomato growers. It causes serious damage when it feeds on corn silk and kernels and tomato fruit.

In corn, eggs are laid on silk and the caterpillar hatches and feeds on silk and kernels. In tomato, eggs are laid on leaves, flowers or fruit. The caterpillar feeds by burrowing into tomato fruit. The corn earworm prefers warmer climates. Adult moths migrate north from southern states and can overwinter as far north as Ohio and Kansas.
Caterpillars are a common pest of vegetable plants. They can reduce fruit quality and yield by feeding on leaves or fruit. One important caterpillar pest is the corn earworm (Helicoverpa zea). This caterpillar develops into a relatively harmless nondescript moth, but the caterpillar causes major crop damage in corn and tomato. It is also known as the tomato fruitworm, cotton bollworm, soybean podworm, and sorghum headworm. Some experts consider it one of the most damaging pests in the United States.
Identification
Identification of caterpillars can be difficult and may require the assistance of an expert. Caterpillar body color is variable and can change as it grows older. They can be brown, green or even pink. There is usually a pair of narrow stripes that run down the back. There is also usually a white net pattern on the head. Adults are also difficult to identify. They have brown to yellow forewings with a dark spot in the center.
Lookalike
The corn earworm is established in the United States, but it looks identical to the old world bollworm (Helicoverpa armigera) which is considered an invasive pest. In order to distinguish the two species, DNA molecular analysis or dissections must to be performed by an expert. If you find a caterpillar that you are unsure is the corn earworm or the invasive old world bollworm, contact the FDACS-DPI help line at: DPIHelpline@FDACS.gov or 1-888-397-1517.
Pecan producers will soon enter a critical point in this year’s production season in ensuring their trees have adequate moisture. If the current dry period continues as expected into August, water needs will be even more essential.
According to UGA Extension Pecan Management calendar, water needs increase from 120 to 158 gallons per tree per day in July to 300 to 350 gallons per tree per day in August. The needs increase from 1,440 to 1,896 gallons per acre per day in July to 3,600 to 4,200 gallons per acre per day in August.
“If we turn off really hot and dry in August and September, which we have seen happen many times in the past, if you’re not watering adequately during that time, mid-August through September, you can lose a lot of your crop,” University of Georgia Cooperative Extension pecan specialist Lenny Wells said. “Especially when they’re really loaded, there’s a huge water demand there. If they get stressed at all for water in a situation like that, they’ll start aborting nuts. It would be a big problem.
“We really need to get really good kernel fillings. We do need a few timely rains during that mid-August to that mid-September period to really help us get kernels filled like we need. Especially when the trees are this loaded.”
Irrigation will be critical. According to Pam Knox, UGA Extension Agricultural Climatologist, hot and dry conditions are expected to persist throughout the Southeast for the next month.
Clemson Extension agents provided updates in The South Carolina Grower this week about the status of various crops being produced throughout the state.
Statewide
Dr. Matt Cutulle reports, “It is always good to control goosegrass even if it is past the critical period for competition with the crop. Lack of late-season control made hand-harvesting tomatoes difficult. Also, there will be a huge deposit of goosegrass seeds into the soil seed bank for next year unless the seeds are destroyed after the harvest.”
Coastal

Zack Snipes reports, “We experienced a nice hot week of weather in the Lowcountry. Most crops are finishing up with the heat and recent rains. On later season tomato I have seen bacterial leaf spot on the fruit which makes fruit unmarketable. I am seeing this on the second cluster of fruit set and not on the first or third clusters. Hemp seems to be off to the races and looking pretty good so far. There are within every hemp field occasional wilted, stunted and yellowed plants. These plants always have a weak root system and most of the time have girdling and interveinal discoloration. Peppers and eggplants are loving this heat and are producing in high volumes.”
Midlands
Justin Ballew reports, “Last week was hot and mostly dry, though we did have some scattered thunderstorms come through over the weekend. Field prep for fall crops continues. We’ve had some fall tomatoes, peppers, and brassicas transplanted already and more to come this week. Everything is growing pretty fast right now and we’re still picking spring crops. Keep an eye out for spider mites, as they love the hot, dry weather we’ve had lately.”
Sarah Scott reports, “We are still ahead of schedule on peach varieties being harvested. Early August Prince and August Prince are being picked now which is over a week earlier than usual. The fruit quality is still good with slightly smaller than ideal fruit. With the extreme heat and lack of rain in the past week, summer crops like tomatoes and cucumbers are looking rough. Bell peppers are doing well.”
Pee Dee
Bruce McLean reports, “Sweet potatoes are looking good. Establishment seems to be very good for the most part. Long green cucumbers, yellow squash, zucchini, cantaloupe, peas, okra, and sweet corn are harvesting well. Condition is good to very good. Sweet corn will be wrapping up shortly. Blueberries are pretty much finished, with only a few remaining fruit on Powderblue. Fruit condition is fair to good. Muscadines are coming along nicely and appear to have an excellent crop. Fresh muscadines should be beginning harvest soon, with wine/juice grapes still a few weeks from harvest. Be on the lookout for Grape root borer moths. They are starting to emerge. They were being caught in traps placed in vineyards in Marion and Horry counties.”
Tony Melton reports, “Harvested first crop of processing peppers. Continuing to pick and plant pickles. Processing greens are over for the spring crop. Harvesting the first crop of processing and seed peas and planting fall crop. Getting processing tomatoes out of the field as quickly as the plant can take them. Things are drying out, hope we don’t go into drought with the heat.”
Upstate
Kerrie Roach reports, “Spotty rain and high temperatures have left many small growers scrambling for irrigation options throughout the Upstate. Peaches and nectarines are still being harvested. Blueberries are just about finished, and farmers’ market produce is starting to wind down with the heat. Apples should begin next week with early varieties like ‘Ginger Gold’ and ‘Golden Supreme’.”
Andy Rollins reports, “Plenty of early blight, bacterial spot/speck on tomatoes this season, but some of the more troublesome problems have been various tomato virus problems. When diagnosing virus problems it is important to get lab verification because herbicide injury can look very similar when just going by visual symptoms. If you suspect herbicide drift from a neighboring farm. Look for damage to other broadleaf plants in the area in between the suspected source and the damaged plants. Follow the wind direction. You should have more severe damage on the leading edge. Also, herbicide residual from a previous crop like sunflowers can also give you herbicide damage that you did to yourself. Read and follow all pesticide label directions. There are plant back restrictions on some herbicides so be careful. If this is the case the damage should be fairly consistent/uniform throughout the area that was planted in the other crop.
Unlike both of these other situations, virus problems may come from your seed source, the greenhouse where plants were grown or from weeds in the field. Pokeweed is commonly a source, as are many other broadleaf weeds. Thrips, aphids, and whiteflies are all known to vector viruses into plants. Symptoms are what you see below with “shoestring” looking leaves, leaves with distorted veins, and mosaic yellow and green coloration. There are many viruses that infect plants. Each of them can show different symptoms and also they can each look different on other plants as well. It’s even possible for a healthy-looking plant with no symptoms to be infected with several viruses.”
It is never too early start thinking about next year’s Southeast Regional Fruit and Vegetable Conference. In the age of the coronavirus pandemic, industry leaders like Charles Hall, executive director of the Georgia Fruit and Vegetable Growers Association, must start thinking about an event still several months away.
“We’re operating on the premise that we’re going to have a show in January in Savannah (Georgia). But we’re looking at, if the outbreak doesn’t calm down, if the requirements are such that we can’t hold the show, we’re looking at what the options are,” Hall said. “We’re just trying to do some preliminary, looking at different ways of doing that and whether we have virtual shows, live presentations. We’re just hoping that things calm down enough that we can have the show and get things going from there.”
Scheduled for Jan. 7-10
The conference is slated to be held in Savannah, Georgia on Jan. 7-10. It’s one of the largest events in the Southeast. It attracts 3,200 attendees and 280 companies that have booths to showcase their agricultural products.
Hall believes a final decision will be made in the fall on whether the conference will be in-person or virtual. A lot will depend on the availability of companies being able to travel for meetings at that point.
“If some of the national companies make the decision that their employees can’t travel in January, that will begin to affect our decision of whether we do with the conference,” Hall said. “We will have a conference. The real question is, hopefully, we’ll have an in-person conference and not a virtual conference.”
The other dilemma is if the conference proceeds as normal, how will social distancing guidelines be followed with that many people expected to attend?
“Right now, if we had that conference in Savannah, you would have to be at a 50-person maximum in a room. I think is what the requirements are, and then they have to be social distancing. Those classrooms have been wall-to-wall people and they’re standing along the sides, you can’t have that many people in a classroom right now,” Hall said.
Rift in Relations Between U.S. and China Leads to Unpredictability in Initial Agreement
The Phase One Trade Deal between the U.S. and China was supposed to bolster the agriculture industry. According to a prior Southeast AgNet story, China was to increase its purchases of agricultural products by $32 billion over the next two years.
But according to Adam Rabinowitz, Assistant Professor and Extension Economist at Auburn University, it appears China will not reach those goals. Add in the current rift between the two countries because of the ongoing coronavirus pandemic, U.S. farmers are left with more uncertainty regarding a major player in the global export market.
“There’s been some positive components from the Phase One Deal, just that it has opened the door for commodities to move back into China and even some new commodities that had not been moving in that direction before have started to. But it doesn’t appear that they’re going to meet the goals of Phase One from a dollar perspective. Without a Phase Two Deal, it does lead to a question I guess of what the long-term impacts will be,” Rabinowitz said. “From a grower’s perspective, it’s just more uncertainty. There’s difficult financial times to begin with, that we’ve seen over the last few years and then add on top of that, uncertainty in terms of markets; the impacts from natural events and health-related now; it adds that risk and adds to the questions of how do we ensure that we’re going to be able to survive for the next season.”
According to the Sunbelt Expo website, this year’s North Carolina Farmer of the Year is James Lamb.
Lamb is now eligible for the Swisher Sweets Farmer of the Year award and $15,000 cash prize given to the overall winner, who will be named at this year’s Sunbelt Ag Expo in Moultrie, Georgia on Oct. 20-22.
Lamb was nominated as North Carolina Farmer of the Year by Jessica H. Tripp, District Field Representative for North Carolina Farm Bureau Federation.
James Lamb
“Lamb is the type of farmer who does everything in his power to help preserve the agricultural industry as a whole. He’s managed to maintain his farm operation while working full time for Prestage as an environmental specialist, a job that requires a huge commitment of time and energy,” Tripp said.
Lamb built a pig nursery farm on the same 75–acre tract in Clinton where he grew up. He and his family manage the nursery operation and grow corn, soybeans, millet, and Bermuda grass and raise a few cattle. Over the years, Lamb has constructed two swine barns to house his animals and purchased three new tractors and attachments.
He receives weaned pigs at 21 days of age from Prestage’s trucking staff and keeps them for seven weeks or until they are about 50 pounds, and then forwards them to finishing farms until they reach their market weight. At the nursery barn, pigs are provided with ample ventilation and supplemental heat of approximately 82 degrees.
Lamb explained, “Here we have an eight-week cycle or turn that includes a week to clean the facility before the next turn begins. There are approximately 3,040 pigs here at any given time. Given our six-and-a-half cycles or turns per year, this amounts to around 20,000 pigs annually.”
The yields on Lamb’s contract farm are as follows: 4.29 acres of irrigated Bermuda hay yields 6900 lbs.; 5 acres of millet are grazed by the farm’s cattle; 2 acres are planted with sunflowers as a wildlife habitat; and 22 acres of corn and soybeans yield 160 bushels per acre and 40 bushels per acre respectively. There is also an acre and a half of cultivated garden space. The farm has 7 brood cows and 1 bull. Seven calves per year are raised to approximately 400 pounds and then sold to market in Smithfield, North Carolina where they are sent on to a feed lot in the Midwest and grown to a finishing weight of 700 to 800 pounds.
As the North Carolina winner of the Swisher Sweets/Sunbelt Expo award, Lamb will receive a $2,500 cash award, an expense-paid trip to the Sunbelt Expo from Swisher International of Jacksonville, Florida, and a $500 gift certificate from Southern States Cooperative.
A Columbia vest from Ivey’s Outdoor and Farm Supply will be given to each state winner and nominator. Syngenta will donate $500 to the state winner’s charity of choice.
Massey Ferguson North America will provide each state winner with a gift package and the overall winner with the use of a Massey Ferguson tractor for a year or 250 hours (whichever comes first). Southern States Cooperative will supply the overall winner with an additional $500 gift certificate. A Columbia jacket from Ivey’s Outdoor and Farm Supply will be given to the overall winner. Syngenta will provide a $500 donation to the charity of choice for the overall winner who will also receive a Hays LTI Smoker/Grill. In addition, the overall winner will receive a Henry Repeating Arms American Farmer Tribute Edition rifle from Reinke Irrigation.
