Foliar Sprays

Foliar spray is the application of fertilizers, fungicides and pesticides directly on leaves and stem instead of applying them near roots.

They are directly applied on leaves and it helps in preventing pests, eggs, fungi and any infections that occur in any stage of plant growth.

The outer cellular layer of the leaves absorbs the applied fertilizer or fungicide.

Foliar spray is the only solution when roots gets damaged due to insects, infections etc.
