Projects
Four crops are being examined in the Groene Veredeling program: potato, leek, spinach and tomato.
Current projects
Phytophthora resistance in Potato
The Dutch organic potato production is still heavily under pressure, mainly due to the major problems with Phytophthora infestans (late blight), as occurring in warm and moist weather conditions.
Thrips resistance in leek
Thrips is an annual recurring problem in organic and non-organic cultivation of leek. The damage is visible as silver-gray spots on the leaves.
Resistance to aphids in sweet pepper
Aphids can be a major problem in the cultivation of sweet peppers. They cause direct damage to the foliage, flowers and fruits.
Reducing damping-off in spinach
Spinach is an important ingredient of salads, especially the so-called 'babyleaf' salads. Spinach seedlings may die due to infections caused by pathogens such as Pythium. The death of the seedlings is called 'damping off', more specific post-emergence damping-off.
