UC Cooperative Extension will be hosting two field days this month that may be of interest to rotational crop growers who work with small grains. Full agendas are pending, but mark your calendars in the meantime.
1) Thursday, April 21st: Controlling Italian ryegrass in Small Grains: Join us for a series of short presentations on different methods of control for Italian ryegrass. Speakers will include industry representatives and UC researchers. Participants will also have opportunity to observe this year's herbicide trial on-site, which will exhibit the efficacy of several available chemical controls and several different tank mixtures. Discussions will also cover alternative methods for control and...
