Overwhelmingly, Faba beans are grown for the human food/food processing market in Manitoba. As a result, both yield and quality of the harvest become very important. Two summer insect pests are a particular threat. Let’s take a quick look:
Pea Aphids
- Scout for pea aphids from the end of July to mid-August.
- Aphids often hide under the leaves and cluster in areas of new growth.
- The economic threshold for pea aphids in faba beans is 34–50 aphids/main stem and provides a seven-day lead time before aphid populations reach the economic injury level of 96–142 aphids/main stem.
