The effect of BioDefender

The natural plant extracts in BioDefender only fight harmful insects in a quick and efficient way. Natural orthosilic acids have been added to the product to reinforce cell walls. This creates a thin, fully biodegradable layer on the leaf surface, so that insects, fungi and viruses have no chance to penetrate the plant cells and infect the plant. The organic humic acids and fulvic acids ensure a good development of the plant through the leaf. The whole reinforces the natural resistance of the plant to be able to combat pathogens. BioDefender can be used safely up to a week before the harvest time.
