Tobacco Disease Update from Kenny Seebold, University of Kentucky Extension Plant Pathologist

Current situation:
The most common problems affecting float beds at the moment are Pythium root rot and target spot. We may see Pythium become more problematic as temperatures rise and because many growers are holding plants on beds because of poor field conditions. Blackleg (bacterial soft rot) hasn’t been much of an issue to this point, is another disease to watch for as temperatures rise. At this point in the season, growers need to keep a close watch on plants and make sure that fertilizer levels are not so high as to promote rapid, lush growth of plants. Steps should be taken to keep air moving on plants to keep them as dry as possible. Regular clipping will help keep the lower canopy dry in float beds, but make sure that this operation is carried out when plants are relatively dry. When clipping, it’s important to remove only one-half to one inch of leaf at a time to minimize deposition of leaf matter on trays AND injury to plants. Remove any trays affected by blackleg or collar rot (Sclerotinia) before clipping, and replace them with empty trays to avoid spreading disease throughout the float bed. Sanitize mowers with a 10 percent bleach solution after each use. For Pythium root rot, Terramaster 4EC can be applied up to five days before setting as long as the seasonal limit of 3.8 fl oz/100 gallons of float water has not been exceeded. For prevention, add .7 to 1 fl oz/100 gallons of float water, and if the disease is active, use 1 to 1.4 fl oz/100 gallons.  

Blue Mold
Blue mold has not been reported in the U.S as of May 20. I will send out updates if this situation changes.

Central Kentucky Premier Heifer Sale:  June 1 at 1 p.m.
The Central Kentucky Premier Heifer Sale will be June 1, 1 p.m. at the Marion County Fairgrounds. This group was organized in 2004 in an effort to market top quality replacement females produced in progressive herds in central Kentucky. Producers from Marion, Nelson and Washington counties joined efforts to insure a large group of heifers could be assembled and only the top quality females would be accepted into the sale. The group held its inaugural sale on June 4, 2055 with an offering of 156 females. We have continued to increase the number of cattle offered and currently market approximately 400 head per year through the sale. There are two premier heifer sales held each year. The first Saturday in June offers fall calving dates beginning Sept. 1. The second sale is held on the first Saturday in November featuring spring calving heifers with calving dates beginning Feb. 1.

Each female is screened by the Kentucky Department of Agriculture for quality, structure, attitude, and must pass a complete health and vaccination program. All heifers are reproductive track scored and pelvic measured prior to breeding. Many of the females are artificially inseminated to the top bulls in the Angus breed. Each bull used must meet the “Heifer Acceptable” approved status to help insure a stress free calving season.

By working with the University of Kentucky beef specialist, Extension Agents, University and local veterinarians, along with Merial and Boehringer-Ingelheim Vetmedica, a program was established for quality and health that is second to none. It is our intention to provide you with a quality, productive female that will keep you in the cattle business. We look forward to the opportunity to earn your business and develop a long-term relationship built on trust and confidence in our program.  We may not be the biggest, but our goal is to be the best.
