Systems and methods for use of chlorine dioxide in cultivation and post-harvest applications

A method of microorganism control in a plant cultivation environment comprising:

• determining, at a first time and a first location, a first plant biomass parameter;
• determining, at the first time, a first air sample mold spore count from a first air sample collected at the first location;
• determining, at the first time and the first location, a first cultivation environment parameter;
• determining a first application rate of a gaseous chlorine dioxide in response to one of the first plant biomass parameter, the first air sample mold spore count, and the first cultivation environment parameter, wherein the first application rate is calculated to produce one of an estimated gaseous chlorine dioxide concentration and a measured gaseous chlorine dioxide concentration;
• applying the gaseous chlorine dioxide in the plant cultivation environment at the first application rate for a first treatment period;
• determining, at a second time, a second air sample mold spore count from a second air sample collected at the first location;
• and
• determining a microorganism control effect produced in response to the applying the gaseous chlorine dioxide for the first treatment period by comparing the second air sample mold spore count to the first air sample mold spore count;
• wherein the plant cultivation environment comprises an indoor cultivation facility, and
• wherein the applying the gaseous chlorine dioxide at the first application rate for the first treatment period is effective to reduce the air sample mold spore count from the first air sample mold spore count to the second air sample mold spore count.
