Some chemicals may contain products that will kill off these bacteria. Compatibility test reports are available. Testing is available for chemicals not on the approved list at no cost. When you first apply Mity-Gro chemicals in the soil will not pose a problem. In the process of time Mity-Gro will consume the good, the bad and the ugly as it generates high energy food for the plant.
Chlorine can also kill the bacillus but the normal amount found in most city water is acceptable.
If unsure, a chlorine test should be done. Avoid spraying pesticides and fungicides directly in to the soil, but overspray hasn't been a problem. Plants with major problems will take longer for the bacteria to heal, regenerate and balance growing conditions. The process of handling and using Mity-Gro to its greatest potential is still being realized. This bacterium is successfully producing high quality plants, cutting costs and boosting production while combating destructive organisms.
