Asparagus
Continue scouting for asparagus beetle eggs on emerging spears.
Greenhouses
Be scouting for aphids and spider mites on transplants. Be sure to check labels before making any application decisions. Some labels are specifically for greenhouse application, others specifically state not for greenhouses, and still yet others are silent, even if the active ingredient is the same. Your state’s Department of Agriculture or county extension agent can give you guidance on how to interpret this last category. Some of the earliest transplants will soon be set outside to harden off. For infested transplants, this is a very convenient time to treat them because an application can be made using far less product and water and in much less time.
