In many neighborhoods, people envy the individual with the most beautiful lawn and think they cannot grow a lawn of equal quality. That is not necessarily true. A well-maintained lawn only requires some knowledge about fertilization, watering, pest control, and mowing. This publication provides basic information about fertilization. By far, the best approach to a proper fertilization program is to start with a soil test, but, if a soil test is not available, these guidelines can be used for a general turfgrass fertilization program. Original publication date May 1991. Revised August 2013 and August 2015.

Pillbug, Roly-Poly, Woodlouse Armadillidium vulgare (Latreille) (Malacostraca: Isopoda: Armadillidiidae)
The roly poly is an isopod, a type of non-insect arthropod also known as a terrestrial crustacean. It is called a roly-poly because it rolls into ball when disturbed. This defensive behavior also makes it look like a pill, which is why it is sometimes called a pillbug. In Europe, the name woodlouse is used for both roly polies and sowbugs because these arthropods are frequently found under logs. Roly polies are nocturnal, though they may be found during the day in the soil or under debris. They are beneficial in the garden or landscape. This 3-page fact sheet about the humble roly poly was written by Julie A. Franklin, Morgan A. Byron, and Jennifer Gillett-Kaufman and published by the UF Department of Entomology and Nematology, August 2015. (Photo by James Castner, University of Florida)

Turfgrass Herbicides: Mechanisms of Action and Resistance Management
Herbicides are an effective tool for controling weeds in turfgrass; however, weeds can become resistant to herbicides and create significant problems for turfgrass production. The best way to combat herbicide resistance is to rotate herbicides with different mechanisms of action (MOA) because using herbicides with different MOAs makes it more likely that weeds resistant to one herbicide will encounter an herbicide to which they are not resistant. This 4-page fact sheet focuses on how to create an herbicide program that uses different MOAs to manage resistant weeds. Written by Ramon G. Leon and Bryan Unruh, and published by the UF Department of Agronomy, August 2015.

Black Scale Saissetia oleae (Olivier, 1791) (Insecta: Hemiptera: Coccoidea: Coccidae)
The black scale is an important pest of citrus and olive trees. Originally from South Africa, this scale is now distributed worldwide. In Florida, black scale is found on citrus, cultivated olive, avocado, and many popular landscape plants. It is likely that black scale, like many invasive pests, was imported to the United States on infested nursery plants. Based on their small size and the unique life history of scale insects, these insects are difficult to detect and control. This 4-page fact sheet was written by Morgan A. Byron, Jennifer L. Gillett-Kaufman, and Sandra A. Allan, and published by the UF Department of Entomology and Nematology, March 2015. (Photo credit: Lyle Buss, UF/IFAS)

Black Turpentine Beetle, Dendroctonus terebrans (Olivier) (Insecta: Coleoptera: Curculionidae: Scolytinae)
Black turpentine beetles bore into the inner bark of stressed or injured pines, where they breed and feed on phloem tissue. Adults are strongly attracted to volatile pine odors and readily breed in fresh stumps. In typical forests, infestations do not exhibit the rapid and devastating expansion characteristic of the closely related southern pine beetle, but in stands where stress conditions are frequent or persistent, black turpentine beetle can become a chronic pest and cause significant mortality over an extended period of time. Historically, black turpentine beetle has been a major pest of pines wounded or treated with herbicides in naval stores production. During the 1950s, black turpentine beetle damaged 37 million board feet of timber and contributed to the financial collapse of turpentine farms. This 5-page fact sheet was written by Albert E.

Contaminants in the Urban Environment: Dioxins
Dioxins are among the most toxic chemicals on the earth. They are by-products of a number of human activities such as combustion of fuels and wastes containing polyvinyl chloride (PVC), chlorine bleaching of paper products, and selected industrial processes. Current releases of dioxins by humans are due to the combustion of fuels and burning of household trash. The good news is that levels of dioxins in the environment have decreased in the United States throughout the past 30 years due to the improved emission controls and regulatory activities. But dioxins break down slowly, so they remain in the environment for a long time and accumulate in the food chain. Long-term exposure to dioxins can harm immune system, nervous system, endocrine system, and reproductive functions. This 7-page fact sheet discusses the sources, emission trends, and impacts of dioxins as well as the ways to minimize exposure to dioxins. Written by Yun-Ya Yang and Gurpal S. Toor, and published by the UF Department of Soil and Water Science, July 2015.
