We are within a few weeks of the anticipated initial emergence of grape root borer (GRB) adults here in Georgia. If you are planning on implementing mating disruption as a management tactic for GRB and you haven’t deployed your pheromone dispensers/ties, now is the time to get those distributed.

I think most producers are fully aware that recent rainfall events will increase disease levels in wine grapes. I am particularly concerned about fruit rots and downy mildew.

Most bunch grape vineyards in Georgia are well into bloom or early…
