Extractions: CLEMSON UNIVERSITY INTRODUCTION A weed can simply be defined as any plant growing out of place or growing where it is not wanted. For example, tall fescue may be considered a weed when grown in a stand of bermudagrass or Kentucky bluegrass, but it is desirable when grown as a monoculture. Reasons for classifying a plant as a weed are numerous. In addition to being unsightly, weeds compete with turfgrasses for sunlight, soil nutrients, soil moisture, and growing space. Weeds also act as hosts for pests such as plant pathogens, nematodes and insects. Certain weeds cause allergic reactions in humans due to their pollen or their volatile chemicals. Probably the most undesirable characteristic of weeds in turf is the disruption of the uniformity of a turf. Different leaf width and/or shape, different growth habit, and/or different color contribute to unsightliness. For example, many broadleaf weeds such as dandelion, plantains, and pennywort have leaf widths different from turf. Goosegrass, smutgrass, and dallisgrass tend to form clumps or patches which disrupt turf uniformity. In addition, large clumps are difficult to mow effectively which increases maintenance problems. Turf uniformity also is disrupted by the presence of weed seedheads. Annual bluegrass, for example, is largely unnoticed in cool-season turfgrasses until numerous seedheads appear in late winter and spring.

Extractions: A weed can be defined as any plant growing out of place or growing where it is not wanted. In a turf situation, for example, tall fescue may be considered a weed when grown in a stand of bermudagrass or Kentucky bluegrass, but it is desirable when grown as a monoculture. Reasons for classifying a plant as a weed are numerous. In addition to being unsightly, weeds compete with turfgrasses for light, oxygen, soil nutrients, soil moisture, carbon dioxide and space. Weeds also act as hosts for pests such as plant pathogens, nematodes and insects. Certain weeds cause allergic reactions in humans due to their pollen or their volatile chemicals. Probably the most undesirable characteristic of weeds in turf is the disruption of the uniformity of a turf. Different leaf width and/or shape, different growth habit, and/or different color contribute to unsightliness. For example, many broadleaf weeds such as dandelion, plantains, and pennywort have leaf widths are different from turf. Goosegrass, smutgrass, and dallisgrass tend to form clumps or patches which disrupt turf uniformity. In addition, large clumps are difficult to mow effectively and they increase maintenance problems. Turf uniformity also is disrupted by weed seedheads. Annual bluegrass, for example, is largely unnoticed on putting surfaces until prolific seedheads appear in late winter and spring. These seedheads also disrupt the smoothness and trueness of the turf's playing surface (Fig.1).

Extractions: Subcommittee Reports I. Apiculture Keith S. Delaplane The number of managed bee hives in Georgia increased from 70,000 in 1995 to 75,000 in 1996 . This welcome upswing follows a general increase in honey prices due to decreasing world honey stocks. Overall honey production in Georgia, including the 1996 crop year, has stayed uniform over ten years . Thus, production efficiency is good. Parasitic tracheal mites and Varroa mites continue to kill colonies and cost beekeepers large sums for control. There remains only one registered miticide for varroa mite control, Apistan TM . There is concern for chemical resistance in mites but so far there are no data from North America to suggest this is a problem. Conditions were good for honey production in 1996. Beekeepers with five or more hives harvested 5,100,000 pounds of honey, up from 4,340,000 in 1995. Production per hive (68 pounds) was up slightly from 1995 (62 pounds). Value of the 1996 crop was $4,539,000 compared to $3,081,000 in 1995. In 1996, average price per pound rose to $0.89, up from $0.71 in 1995 Extension programs reached 1,876 people in educational efforts aimed at honey bee parasite biology and control, optimum bee management, and public awareness of the value of bee pollinators. The fifth annual Young Harris College/University of Georgia Beekeeping Institute drew 99 participants. Research focused on identifying economic treatment thresholds for Varroa mites and the pollinators and their flower-visiting behavior in rabbiteye blueberry.
