Plant-parasitic nematodes are a major pest on potatoes in Florida. Root-knot, sting, and stubby-root nematodes are the primary problems. Sampling is an important component of confirming nematode problems in a field. Nematode management relies heavily on chemical control (nematicides), but crop rotation and soil culture are important considerations as well. This 12-page fact sheet about nematode management in potatoes was written by Zane J. Grabau and J.W. Noling and published by the UF Department of Entomology and Nematology.
Foliar or bud nematodes are little-known nematodes that caused “crimp disease” in Florida strawberries in the early 1900s. Recently, these foliar nematodes have been observed again in the state, and seem to have come in with transplants from outside Florida. Foliar/bud nematodes can devastate a crop of strawberries. Plants become stunted with curled up leaves, and produce few or no flowers or fruits. This 7-page fact sheet written by J. Desaeger and J. Noling and published by the UF/IFAS Department of Entomology and Nematology provides much-needed information on these little-understood pests, summarizing the different types of foliar nematodes, their biology, life cycle, damage symptoms, survival strategies, dissemination, and management options.
With the new fumigant regulations and rising cost of crop production, including fumigants, it would be desirable to reduce the standard use rate of soil fumigants. The use of higher-barrier, gas-impermeable mulches may make it possible to reduce fumigant application rates by helping to contain the fumigant longer within the soil and reduce overall emissions into the atmosphere. The results of field studies show that fumigant application rates can be reduced by 20 to as much as 40% through the use of virtually impermeable or the more gas-tight TIF mulch films at the time of application. This 5-page fact sheet was written by J. W. Noling, and published by the UF Department of Entomology and Nematology, March 2013.
This 3-page fact sheet lists of multispectrum fumigant nematicides currently registered for use on different Florida crops (Table 1); their maximum rates and specific details for field application (Table 2); and a generalized summary of maximum use rate and relative effectiveness of various soil fumigants for nematode, soilborne disease, and weed control in Florida (Table 3). Written by J. W. Noling, and published by the UF Department of Entomology and Nematology, January 2013.
Calibration of soil fumigant equipment and determination of soil fumigant application rate are two of the most important factors contributing to the success or failure of pest control efficacy and crop production response, yet generate some of the greatest confusion among many researchers and growers alike. This 5-page fact sheet was written by J.W. Noling, and published by the UF Department of Entomology and Nematology, December 2012.
