Abstract
Abstract In 1963 and 1964, increases in boll rot of cotton were associated with short periods (5 to 7 days) of rainfall and, to a lesser extent the drying period following rainfall. Microclimate changes within the plant canopy associated with these periods indicate that increased duration of relative humidity at a level of 95% or higher, increased duration of free moisture, and reduced intensity of light, all favor boll rot development. Bottom defoliation reduced boll rot loss and modified the microclimate resulting in shorter duration of 95% or higher relative humidity; it increased light intensity in the lower plant zone, and possibly increased ventilation following periods of rainfall. Instrumentation used for microclimate measurements are described; and construction details of a simple mechanical psychrometer and a light intensity sensor‐recorder are presented.
