Thriving Cucumber Crops with the magic of Blue Leaf

Plants can vary in their ability to fend off diseases and pests. At Rijk Zwaan, we're experts at breeding for cucumber plants with a natural strong resistance. You can spot them by the Blue Leaf label. These unique cucumbers feature dark blue-green leaves, thanks to extra chlorophyll, promoting longevity in your cucumber crop. For instance, they exhibit delayed yellowing in the event of an infection with the cucurbit yellow stunting disorder virus (CYSDV).

The magic of Blue Leaf…

Elevates photosynthetic activity

Blue Leaf varieties boast greener leaves, thanks to extra chlorophyll. This abundance helps them utilize light more efficiently during the cultivation period, promoting a healthier assimilation process in the plant.

undefined
Optimizes Crop Resilience

A green crop is more active and is therefore better able to cope with climate changes and attacks of diseases and pests.

undefined
Extends the growing season

The plants maintain better health and prolonged productivity due to increased root strength and an improved vegetative/generative balance.
