Second DD update for billbugs in orchardgrass

The number of accumulated degree-days (DD) for bluegrass and hunting billbugs in orchardgrass since 1/1/11 are starting to move. As of 4/6/11, 214 DD have accumulated. Model forecast for 4/13/11 is 284 DD. Recall that at least 280 DD are needed before taking any action. Within the next week or so you need to start checking your field borders for paired-field holes.
