Serifel
Serifel is a protectant biological fungicide for the reduction of fruit damage caused by Botrytis cinerea (grey mould) in protected strawberries, raspberries, blackberries, blueberries, loganberries and Rubus hybrid; the moderate control of Botrytis cinerea in protected tomatoes, aubergines, pepper and chilli pepper and the moderate control of Botrytis cinerea and Sclerotinia species in protected lettuce and other leafy crops.
Benefits
- Residue-free solution which allows for greater flexibility in application throughout the growing cycle
- Rainfast within 3 hours of application
- IPM compatible (safe on predatory mites Amblyseius swiskii, Phytoseiulus persimilis; the predatory bug Nesidiocoris tenuis and the parasitoids Diglyphus isaea and Eretmocerus eremicus)

| Other specific restrictions | For crops to which ‘permanent protection with full enclosure’ applies: Treatment must only be made under ‘permanent protection’ situations which provide full enclosure (including continuous top and side barriers down to below ground level) and which are present and maintained over a number of years. Reasonable precautions must be taken to prevent access of birds, wild mammals and honey bees to treated crops. To minimise airborne environmental exposure, vents, doors and other openings must be closed during and after application until the applied product has fully settled. The use of this product in recirculating water systems in a greenhouse may result in dilute pesticide waste that requires disposal. All dilute pesticide waste must be disposed of safely and legally to protect humans, wildlife and the environment, especially groundwater and surface water. Pesticide disposal advice is detailed in the ‘Code of Practice for Using Plant Protection Products (Section 5: Disposing of Pesticide Waste). |
Why Serifel?
- Serifel® forms a “shield of protection” against a broad spectrum of pathogens thanks to its three modes of action, enabling the production of top-quality produce with the lowest possible residues and helping to combat the development of resistance. ·
- Serifel® allows flexible application throughout the growing period. It can be used on a wide range of crops:

Description
How does it work?
Serifel® as a contact biological fungicide has multiple modes of action:
- Production of antifungal metabolites - creates physical damage of pathogen cell membranes
- Physical exclusion – excluding bacteria and fungi pathogens from space
- Nutrient competition – excluding bacteria and fungi pathogens from food

Serifel® mode of action - Production of anti-fungal metabolites
Serifel® grows on the plant surface, reproducing cells which release metabolites, which disperse to create a zone of exclusion where pathogens cannot germinate or grow.
