More about BioDefender

BioDefender contains natural plant extracts which only fight harmful insects quickly and efficiently. To reinforce cell walls, natural orthosilic acids have been added to the product. Insects, fungi and viruses have no chance to penetrate the plant cells as a the orthosillic acids create a thin an fully biodegradable layer on the leaf surface.
A good development of the plant is ensured by the organic humic and fulvic acids. All together it reinforces the natural resistance of the plant to combat pathogens.
BioDefender can be used safely up to a week before harvest time.
