Orchards and berry crops are characterised by the presence of a peculiar microflora specific to this growing environment. Maintaining the right composition of beneficial microorganisms on the plant surface is key to maintaining plant health, fruit health and increasing the storage value of the crop. GARD H is an effective biopreparation for the hygienisation of orchard and berry environments. The bacteria in the formulation rebuild the natural microflora on the plants. Due to their high concentration and high multiplication capacity, beneficial bacteria colonise the plant in a way that is competitive with pathogenic microorganisms by limiting the surface area for their growth. Thus, they support healthy plant development and improve crop yields.
