Week 11

Good morning everyone, it's week 11 and spring is almost officially upon us! That means pest pressures are going to start increasing and many greenhouses are reaching full capacity with new spring crops. Here are some of the mains things we observed this week in the field;

1. Fusarium wilt in Cyclamen is suspected at one of our clients. Over the past few weeks the cyclamen in this house have been showing the following signs: wilting (cyclamen typically have very stiff/hard foliage) of leaves and flowers, dieback of some shoots and necrotic (dying) spots on the leaves. We also noticed distortion of the flowers that is similar to thrips damage. The plants looked generally unwell as if they had been experiencing heat stress. On the plants that were farther along the roots were brown and soft/breaking apart easily and the plant was heavy with water because it had not been able to keep up. After a colleague broke open a corm and showed us the red striping inside (indicating fusarium) the grower knew what to treat for.
