Pests
Thrips on Broccoli Plants
Commonly affects: Brassica oleracea var. italica (Broccoli)
Silvery streaks and small dark specks appear on leaves, with distorted new growth in heavier infestations, most noticeable in warm, dry weather.
Potential Causes
- 1Thrips feeding on leaf surfaces, rasping tissue
- 2Warm, dry conditions favouring population growth
- 3Nearby infested plants or weeds seeding new populations
Solution Steps
- 1Use blue sticky traps to monitor and reduce adult thrips
- 2Apply insecticidal soap for active infestations
- 3Remove heavily damaged leaves to reduce the population reservoir
- 4Keep the growing area free of weeds that harbour thrips
Prevention Tip
Thrips are a secondary pest on broccoli in most gardens â moderate populations rarely require aggressive intervention.
