In general, insect pressure has been relatively low this year. However, over the past week we have noticed an increase in insect activity.
Start scouting for European corn borer at the mid-whorl stage, before the tassel begins to emerge from the plant. Look for flattened, white egg masses on the under surface of the leaves. Newly hatched larvae often hide in the developing tassel during the heat of the day. Window panes, pin-hole feeding and small amounts of saw dust-like frass are all signs of feeding. Optimal control occurs during the early stages of insect development, before the larvae enter the stalk. Young larvae range in colour from almost translucent to yellow to brownish, with a black head.
The website, insectforecast.com reports scattered flights of corn earworm into the great lakes region. Corn is susceptible to earworm infestation during the silking period. The best way to monitor for the presence of corn earworm is with a pheremone trap. Continue reading Watch for Increased Insect Activity in Sweet Corn and Pumpkins
Cucumber beetles are the primary vector of bacterial wilt. Even a fairly low population of beetles can spread this disease across the field. Once infected, there is no cure for this disease. Plants will rapidly wilt and die, effectively reducing the plant stand and the yield potential. Cucumbers are the most susceptible to bacterial wilt followed by melons, pumpkins and zucchini.
