Integrated Pest Management for Mosquito Reduction around Homes and Neighborhoods
This 40-page publication describes how homeowners can use an integrated pest management (IPM) program to help decrease pesticide use, reduce the risk of contracting mosquito-borne diseases, and ease the financial burden on local governments responsible for area-wide control. Modern mosquito control emphasizes source reduction to eliminate areas where mosquitoes thrive; surveillance to determine whether pesticide applications are necessary; screening; sanitation; and other techniques described in this document. The methods recommended in this publication are particularly effective in reducing mosquitoes that transmit diseases. Homeowners who take responsibility for identifying and eliminating sources of mosquito production around their homes and neighborhoods will improve health and quality of life for all Florida residents.

Fertigation for Vegetables: A Practical Guide for Small Fields (HS1206)
More and more farmers are growing small crops of fruits and vegetables for specialty local markets. They commonly grow several crops at different stages of development at the same time so they have a variety of produce to sell to customers. This forces farmers to make several fertilizer calculations because of their diverse crop demands, because water and nutrient requirements vary according to the crop and stage of development. This 7-page fact sheet helps growers correctly interpret fertilizer recommendations and calculate accurate fertilizer amounts to be used based on crop nutrient requirements. Written by Jim DeValerio, David Nistler, Robert Hochmuth, and Eric Simonne, and published by the UF Department of Horticultural Sciences, October 2012.
