Organic mulches colonized with microbial biocontrol agents (BCAs), termed bioenchanced mulches, were tested for their ability to reduce Phytophthora root rot of avocado. The BCAs were first evaluated for their ability to colonize different mulches. Some of the possible specific mechanisms of P. cinnamomi suppression were investigated. Soils treated with mulches for more than 12 months under field and greenhouse conditions resulted in high levels of organic matter. Bioassays using tension plates and soil columns indicated that accumulation of organic matter in the soil trapped or inhibited movement of zoospores and reduced the disease incidence. Bioassays in Petri plates indicated that soils with high microbial activity reduced the survivability of P.cinnamomi zoospores. |
