A bell pepper field had phytophthora problems severe enough to cost the entire crop.
Ridomil Gold treatments were known to be completely ineffective.
Instead of anti-biotics, we applied pro-biotics, microbial inoculants of mycorrhizal fungi, a range of bacterial species, and biostimulants through the drip irrigation system.
Within weeks the soil is filled with these thick strands of mycelium/plant roots and the crop recovered completely.
The phytophthora symptoms disappeared.
What have you seen something similar to this in the soil? What do you think this might be?
