  production that provide producers yield and
  quality that result in maximum economic return,
  while maintaining a sustainable cropping system.
• Address applied production issues that have a
  synergistic effect with pest management,
  mechanization, irrigation, and economic
  stability.

educational efforts of a team of specialists
which work together to provide agents and growers
alike the most up-to-date and factual information
on flue-cured tobacco production, harvesting,
curing and marketing available.

  livestock graze toxic endophyte-infected tall
  fescue pastures.
• Identify limitations to endophyte technologies
  and develop strategies to overcome those
  limitations.
• Develop diagnostic techniques to assist plant
  breeders (forages, small grains, peanuts) in
  quantifying disease and mutualistic organisms
  and/or mycotoxins in plant populations.
