Companion - 1 gallon

Companion® Microbial Innoculant contains beneficial Bacillus subtilis  
GB03, a naturally occurring bacteria that colonizes and lives on
plant roots and root hairs. GB03 is extremely persistent and able to
withstand stressful conditions like heat, drought, and cold.

Companion is 100% natural and contains no chemicals. Because
Bacillus subtilis GB03 excretes IAA-like substances, Companion
encourages healthier, stronger, denser root mass.

The product is easy to use; a valuable tool for resistance
management. Why? A naturally occurring beneficial like Bacillus
subtilis GB03 will crowd out less desirable microbes (pythium,
fusarium), in what amounts to a game of "survival of the fittest".
GB03 quickly adapts to its environment and reproduces more quickly
than other microbes. Companion has no special storage requirements
and it has a shelf life of three years, so you'll always be sure
that every ounce of Companion is consistent in microbial quantity and
quality!

One gallon treats 768 gallons.
