Asparagus
Asparagus is emerging from the soil and air temperatures have been favorable for insect activity. Be on the lookout for asparagus beetle. If 5-10% of spears are infested with adults, or 2% of spears with eggs, treatment may be advised. Please refer to the Mid-Atlantic Vegetable Production Recommendations for treatment options if necessary, which can be found here: http://extension.udel.edu/ag/vegetable-fruit-resources/commercial-vegetable-production-recommendations/.
Brassicas
Imported Cabbageworm adults are active (see the Guess the Pest answer in this edition from last week’s challenge). Begin scouting for worm activity.
