Integrated Pest Management Options

Tarnished plant bug sting plant tissue, including pods and flowers. This causes scarring, malformation and dimpling or pitting on pods. They can also drill into the seed. If flowers are still present, they can prick the flower and cause it to abort. Though no thresholds have been validated for Ontario, spraying is recommended when 2 bugs per sweep are found after petal fall.
