BASF is investing in integrated approaches to crop protection in vegetables, including the use of biological control.
Insect pests: What to look out for
The main insect pest in vegetables are aphids and caterpillars. Main species specifically noted are:
- Cabbage white butterflies
- Diamond-back moth
- Mealy cabbage aphid
- White flies
These pests can cause damage to the vegetables, directly reducing yield and marketability.
Pyrethroid insecticides are the main group of pesticides used. A resistance strategy is urgently needed as resistance to this group has become widespread.
Diseases in vegetables
In Brassicas, the main diseases are Alternaria, ring spot and Botrytis.
Resistance is a real issue so growers are urged to use a number of fungicides with different modes of action. Signum (boscalid and pyraclostrobin) has a strong position in this sector (Brassicas and carrots in particular) because of its broad-spectrum activity and its distinct mode of action.
Sclerotinia is a very widespread and serious disease of carrots:
- It affects both yield and quality
- Growers have the option of integrating cultural and chemical control methods
- A carrot clipping tool has been developed to take off the crop canopy as it flops over and creates the right microenvironment for disease spread
- BASF also offers a Sclerotinia germinating decision support tool for growers and advisors
