Caterpillar pressure varies among crops and regions in South Florida, according to the most recent South Florida Pest and Disease Hotline. Respondents in the Everglades Agricultural Area report most worm pressure on sweet corn is low, but lesser corn stalk borers are moderate in some sandy areas. Caterpillar pressure is low around the southwest Florida area, though there appears to …
Grafting in Tomato: A Practical Tool for Root-Knot Nematode Control
By Abolfazl Hajihassani Control of root-knot nematodes (Meloidogyne spp.) is a severe challenge for growers because the pests have abroad host range and can survive in the soil for several years. This makes crop rotation impractical and inefficient for nematode management. Other major management options for root-knot nematodes in tomato include chemical controls using fumigant and non-fumigant nematicides and resistant varieties/rootstocks. …
Fire Ant Control Key in Young Citrus Groves
Fire ant management is essential to the long-term sustainability of citrus groves. This is particularly true for young trees still trying to develop root systems, said Xavier Martini, assistant professor of entomology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) North Florida Research and Education Center (NFREC). Martini spoke on insect management at the recent UF/IFAS …
Advances in Corn Silk Fly Management and Ecology
By Julien Beuzelin Fall armyworms and corn silk flies are the main insect pests of sweet corn in Florida. Management relies primarily on insecticides, but the two pests represent different challenges. Fall armyworm infestations can be devastating if left unmanaged. However, several registered insecticides such as methomyl (Lannate, Nudrin), chlorantraniliprole (Coragen, Vantacor) or spinetoram (Radiant) are very effective at maintaining …
Time for Peach Producers to Treat for Scale Insects
Warmer temperatures make for a bearable winter in Georgia. But scale insects enjoy them, too. That is a problem for the state’s peach producers. Now is a good time for growers to make appropriate chemical applications, according to the University of Georgia (UGA) Extension peach blog. Brett Blaauw, assistant professor at the UGA College of Agricultural and Environmental Sciences, advises …
Rabbit Management: Conserve Habitat for Predators
By Clint Thompson Management of a South Florida pest starts with conserving the habitat for its predators. That’s what sugarcane and vegetable producers need to keep in mind when managing rabbit wildlife. “I’m going to quote a gentleman who heard about our (rabbit) workshop. He’s a producer in the western United States, and he said they had similar problems out …
Thrips Pressure Expected to Increase in Florida
Thrips pressure is currently low across the South Florida region. But this is the time of year when populations are expected to increase, according to the South Florida Pest and Disease Hotline. Vegetable growers, especially those with crops susceptible to thrips-vectored viruses, need to monitor populations and start management options early. Thrips pressure is starting to increase in most crops …
Whitefly Severity Varies Across Florida
Whitefly populations continue to vary in Florida vegetable fields. According to the South Florida Pest and Disease Hotline, adult whiteflies are being observed in melons, eggplant, tomatoes and peppers in Southwest Florida. Respondents in Homestead indicate that whiteflies are present in tomatoes, beans and squash. Tomato yellow leaf curl virus is widespread in tomato, though most fields are still under …
ABT Populations Low Across South Florida
According to University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), Asian bean thrips (ABT) populations continue to show a downward trajectory in South Florida. The only scouting reports with ABT detected in blooms were observed in both the Clewiston and Loxahatchee areas. Both reported at 0.1 per bloom. Respondents in Homestead indicate that populations seem to be lower …
How to Protect Young Peaches from Plum Curculio
The onset of spring means preparing for insect pests if you are a fruit tree producer. Plum curculio is the most destructive insect that attacks early-season fruit. “If you have fruiting trees, especially peaches, now is the time to ramp up your monitoring efforts for plum curculio to determine if and when management decisions will need to be made,” urged …
