Seed Coat

DeltAg Seed Coat is a hopper box seed treatment. It is a micronutrientvitamin-amino acid complex designed to give the seed a boost to get plants out of the ground and growing. It has a talc/graphite base and can be used in their stead.

Formulated to enhance bacterial activity in the root zone near the seed and to feed the newly emerging roots. This chemistry promotes development of mycorrhizae as well as beneficial bacteria to help the plant extract nutrients from the soil.


Seed Coat is designed to help increase the numbers of micro-flora in the rhizosphere, including mycorrhizae as well as nitrogen fixing bacteria for legumes, and others that are present and necessary for healthy plant growth.

Seed Coat doesn’t replace inoculant, but will enhance its performance.
