By Clint Thompson With the domestic workforce almost non-existent, Southeast vegetable and specialty crop producers rely on the H-2A program now more than ever. Data from the U.S. Department of Agriculture Economic Research Service outlines the growth the program has made over the past decade. Certified H-2A positions increased substantially from 2010 to 2019. The number more than tripled from …
Sanitation Remains Key in Whitefly Control
By Clint Thompson Sanitation of vegetable crops susceptible to whiteflies remains a key management strategy for Florida producers. Hugh Smith, an associate professor of entomology and nematology at the UF/IFAS Gulf Coast Research and Education Center, encourages growers to clean up their fields properly following harvest to reduce the risk of feeding damage and potential viruses. “If you don’t make …
Lingering Problem: Imports’ Impact Being Felt Across Country
By Clint Thompson Imports are no longer a Southeast issue. They are quickly becoming a national issue. Unfortunately, the rising tide of imports of fresh fruits and vegetables impacting other parts of the country may be a necessary step in resolving this growing problem. “Certainly, Georgia has been in this fight with us for a long time and have done …
Weed Management with Fumigants
By Nathan Boyd Fumigants are the cornerstone of pest management programs in most high-intensity plasticulture production systems. They are used to manage soil-borne pathogens, nematodes and weeds. Fumigants have been broadly adopted because they reduce pest populations prior to crop establishment and provide a means to control pests for which there are no other viable alternatives. In addition, fumigants enable …
Plant Breeding Remains Key to Fusarium Wilt Management
By Clint Thompson The key to eliminating fusarium wilt disease’s impact on watermelons in the Southeast is developing disease-resistance cultivars, says Nick Dufault, University of Florida/IFAS plant pathologist. “Where we stand is we’re trying to work with breeders and get new lines of resistance out there,” Dufault said. “We’re gaining a new understanding of the pathogen. I think we made …
Tropical Storm Fred’s Potential Impact on Pecan Production
By Clint Thompson The looming landfall of Tropical Storm Fred could impact pecan production in Georgia and Alabama. But it could have a positive effect. Lenny Wells, University of Georgia Cooperative Extension pecan specialist, said extra rainfall at this stage of production would benefit the crop heading into harvest. As for the wind effect, that’s a different matter. “We’re just …
Artificial Intelligence: UF Scientists Use AI to Predict Citrus Yield More Accurately
IMMOKALEE, Fla. – The implementation of artificial intelligence (AI) helps citrus growers better forecast their production. So far, they’ve found in a University of Florida preliminary study, its technology predicts yields with 98% accuracy. That’s a substantial increase from the 75% to 85% accuracy growers get when they count their trees manually, said Yiannis Ampatzidis, a UF/IFAS associate professor of …
A Look at What’s in the Citrus Breeding Project Pipeline
Proposed research endeavors will mine the rich varietal pool established in recent years.
Expo Pre-Registration Closes Aug. 12
Pre-registration for the upcoming Citrus, Vegetable and Specialty Crop Expo, scheduled for Aug. 18-19 in North Fort Myers, Florida, closes Thursday, August 12 at 11:59 a.m. The annual conference returns to an in-person event this year after last year’s virtual show amid the coronavirus pandemic. The two-day event will feature a citrus session on Wednesday, Aug. 18. Growers and industry …
Lack of Consistency: Fumigation Erratic in Control of Weeds
By Clint Thompson Florida vegetable producers hoping to control weeds with just fumigation need to be mindful of its erratic effectiveness, says Ramdas Kanissery, a weed scientist at the University of Florida/IFAS Southwest Florida Research and Education Center. “The thing with fumigation, what we have observed, there will be good effects on nematode suppression, but when it comes to weed …
