Construction Site Watermelon/Cucurbit Meeting New Web Site Florida Bull Test Sales Currently there are also 62 winter born bulls on test. These bulls will sell on Friday, February 16. The Northwest Florida Beef Conference and Trade Show will be held on Thursday the 15th, the day before the sale, and will provide producers an opportunity to get a better understanding of how the bull test works and how to use the data to select their future herd sires. Dairy Conference Set Beef Management Short Course Weather School 2000 for Agriculture Please help us by pre-registering..... Weather School 2000 is provided through the cooperative efforts of the Agricultural Weather Task Force and the University of Florida. Offered at six locations over the State, the schools are tailored for the agricultural industry in the locale where held. Representatives from Florida State University, the University of Miami and the University of Florida will provide a brief overview of El Nino-La Nina and the level of reliability of long range forecasts. They will also give examples of the types of long range guidance available and how these products can impact agriculture. Representatives of the National Weather Service (NWS) and private weather forecasting services will provide information on forecast products they generate that can be used by agriculture. The afternoon session deals with using weather information. IFAS researchers will discuss one or more corp models that have been, or are under development. Growers can see how weather data can be incorporated into a management tool that can help them with their day to day decisions. Representatives from emergency management will discuss what weather data they utilize to deal with severe situations such as hurricanes, fire, etc., and show how these products can be incorporated into an action plan to protect life and property. The last portion of the school will cover plans for completion of the IFAS Florida Automated Weather Network (FAWN). An outline of the program is provided below.

Weed Control By Plateau in Field-Grown Wildflowers Plateau (imazapic; Cyanamid) is an herbicide labelled for use in noncrop areas such as roadsides and in restoration projects. It is especially useful in these sites because it will kill weeds (and prevent their regrowth) yet allow the growth of many desirable native wildflowers and grasses. On March 15, 2000, Plateau (plus the surfactant Latron B-1956 at 0.25% v/v) was applied over-the-top of field-planted local ecotypes of 3-month-old dye flower (Coreopsis basalis) and 1-yr-old black-eyed susan (Rudbeckia hirta) using a tractor-mounted side boom. Rates of Plateau were 2, 4, or 6 oz product per acre as a single or split application (split = 1, 2, or 3 oz/A applied two times 4 weeks apart). On dye flower, a single application of 2 oz/A resulted in >50% reduction in weed cover 4 and 8 weeks after treatment (WAT). The 2 oz/A rate also caused significant injury (chlorosis, stunting, and/or leaf distortion) at 2 WAT. However, by 8 WAT damage was within an acceptable range, with no apparent injury by 12 WAT. The 1 oz/A rate applied twice provided weed control equal to the 2 oz/A rate but with less damage at 2 WAT. Although the damage from 1 oz/A applied twice was worst at 8 WAT, it was not significantly different than damage caused by the 2 oz/A rate at 12 WAT. On black-eyed susan, the 1 oz/A rate applied twice reduced weed coverage >50% yet caused no significant amount of damage (chlorosis, purplish foliage, stunting, and/or leaf distortion) to black-eyed susan compared to hand-weeded plots 8 and 12 WAT. Weed control provided by Plateau was reduced, especially in the black-eyed susan plots, by the occurrence of annual trampweed (Facelis retusa) and purple cudweed (Gnaphalium purpureum), two apparently Plateau-tolerant weeds. It appeared that without such weed species, Plateau could offer significant weed control in field-grown wildflowers with only minimal damage.
