Applesnails are larger than most freshwater snails and can be separated from other freshwater species by their oval shell that has the umbilicus of the shell perforated or broadly open. There are four species in Florida, one of which is native and considered beneficial. Both the island and channeled applesnails are potential threats to Florida’s aquatic ecosystems.

Cover Crops for Managing Root-Knot Nematodes (ENY063/IN892)
Root-knot nematodes are widespread and are pests of almost all major crops. Damage can be seen as galls or knot-like swellings produced along plant roots. Cover crops are used to manage nematodes because these microscopic roundworms can move only very short distances on their own and will starve without suitable host plants. This 6-page fact sheet describes several common cover crops that can be used for nematode management. Written by Harsimran K. Gill and Robert McSorley , and published by the UF Department of Entomology and Nematology, July 2011.

Recommendations for Management of Whiteflies, Whitefly-transmitted viruses, and Insecticide Resistance for Production of Cucurbit Crops in Florida (EENY478/IN871)
Until recently, squash has been the only cucurbit crop seriously affected by the B biotype of the sweetpotato whitefly, also known as the silverleaf whitefly, because of the silverleaf disorder induced by feeding of the immature stages (nymphs). However, three viruses transmitted by the whitefly have been identified in watermelon, muskmelon, and squash in Florida since 2004, making whitefly management a priority for most cucurbits. This 8-page fact sheet details the current UF/IFAS recommendations for managing whitefly-transmitted viruses and for delaying the development of resistance to insecticides in the whitefly vector.

Spotted Wing Drosophila Drosophila suzukii (Matsumura) (Insecta: Diptera: Drosophilidae) (EENY492/IN887)
Most Drosophila flies are associated with rotten or over-ripened fruits and are nuisance pests. However, a few species such as the spotted wing drosophila, D. suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. First detected within the continental United States in August 2008, D. suzukii has become a serious threat to fruit crops. This 6-page fact sheet was written by Rajinder S. Mann and Lukasz L.

Weed Control for Winter Faba Bean Cover Crop in South Florida (SSAGR345/AG355)
Faba bean is an important leguminous winter crop in warm temperate and subtropical areas that has been cultivated for more than 10,000 years as a source of protein in human and livestock diets. It is also grown to enhance yields of other crops. Faba bean provides nitrogen in agricultural systems through the unique process of biological fixation of atmospheric nitrogen by symbiosis with Rhizobium bacteria. This substantially reduces the need for nitrogen fertilizers, which contribute to both carbon dioxide and nitrous oxide emissions. This 2-page fact sheet written by D.C. Odero provides weed control recommendations. Published by the UF Department of Agronomy, April 2011.

Additionally, allergenic airborne pollen from common ragweed is a primary cause of hay fever and thus a public health concern. This 3-page fact sheet describes the life cycle of the plant and provides management recommendations. Written by D.C. Odero, B. Sellers, and J.

Managing Against the Development of Herbicide-Resistant Weeds: Sugarcane (SSAGR244/SC077)
Although it is likely that small populations of herbicide-resistant weeds are already present in the Everglades Agricultural Area (EAA), herbicide resistance is currently not a significant problem. The continued use of integrated and properly managed weed control programs should ensure that resistance does not become a major issue in the future. In order to successfully manage herbicides against the development of herbicide-resistant weeds, you must have a basic understanding of which herbicides have the same site of action. This revised 4-page fact sheet lists herbicides by group number, site of action, chemical family, common name, and trade name.
