By Clint Thompson Before Florida specialty crop producers begin treating for guava root-knot nematodes, they need to understand what kind of nematodes species is impacting their fields. Not all nematode species can be treated the same, says Johan Desaeger, assistant professor of entomology and nematology at the University of Florida Institute of Food and Agricultural Sciences Gulf Coast Research and …
Guava Root-Knot Nematode More Aggressive, Reproduces Faster
By Clint Thompson The guava root-knot nematode can reproduce faster and be more aggressive than other nematode species. Those are two factors that all specialty crop producers should be mindful of. Johan Desaeger, assistant professor of entomology and nematology at the University of Florida Institute of Food and Agricultural Sciences Gulf Coast Research and Education Center, discussed his findings with …
Soil Health: UF Scientists Receive Grant to Study Fumigation
By Brad Buck, (352) 875-2641, bradbuck@ufl.edu Fumigants are an essential tool growers implement before planting to manage soil health. They reduce harmful diseases such as Fusarium wilt and pests like root-knot nematodes and weeds that compete for water and nutrients.

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. …
