#4 Washing your mower will reduce disease incidence? This one has been proven false in numerous university trials. All turf disease pathogens are soil borne organisms. They are ubiquitous in the environment, so washing your mower has no impact on them. There will still be thousands of turf diseases pathogens in each gram of soil, no matter how many times you wash off your mower.
What about aerators? In reading Cornell University's report on Summer Patch on Turfgrass
Cornell states in the last sentence in the section of Disease Cycle "The pathogen may also be spread by movement of infected plant material and on mechanical equipment". Skipster would you know which equipment they are referring to and what is the process to remove the pathogen from the equipment. Does a 10% bleach solution have any effect.
