Weeds compete with pear trees for light, nutrients, and water. Weed interference can be minimized with proper cultural practices and herbicides. General maintenance, such as controlling weeds in adjacent areas, preventing weeds from producing seeds, and cleaning mowing equipment of weed seed, will prevent weeds from becoming a serious problem. This 6-page fact sheet includes recommendations for herbicides labeled for pear in Florida. Written by Peter J. Dittmar and Jeffrey G. Williamson, and published by the UF Department of Horticultural Sciences, December 2011.
Florida produces some of the earliest commercial-quality peaches and nectarines in North America. During the last 10 years, many new, improved peach and nectarine cultivars have been released by the University of Florida. They have increased the potential for expansion of commercial peach and nectarine acreage throughout much of the Florida peninsula and along the Gulf Coast regions of the southeastern United States. This 3-page fact sheet was written by Mercy Olmstead, Jeff Williamson, Jose Chaparro, and Tim Crocker, and published by the UF Department of Horticultural Sciences, September 2011.
