Several factors appear to have impacted the results of this experiment. The trees in this non irrigated
block were drought stressed throughout the growing season. A light crop set in 1999 may have
effected the results as well. The significant reduction in Nova®40W rates throughout the primary scab
season by the grower may also have effected the treatment results.
