Seedcorn Maggot
We are between seedcorn maggot generations in Georgetown. Peas planted between March 21 and April 1 should be scouted for damage.
Asparagus
Asparagus spears are beginning to emerge. Begin scouting for asparagus beetle and beetle eggs, especially with the warm weather forecast for next week. Asparagus beetles will stick their cylindrical dark eggs at a 90 angle to the stem. Minnesota scouting recommendations suggest to sample 20 plants in each of 5 locations for at least 100 spears/plants. Thresholds are 2% of spears with eggs, 5-10% of plants with adults, and 50-75% of plants with larvae.
