The binomial sampling table is a conversion from the # of leaves with more than 5 mites, to the average number of mites per leaf. The treatment threshold has been set at a nominal value of 5 mites per leaf, average. This threshold allows sufficient time before levels reach 10/leaf, at which irreparable leaf damage can occur. Also consider predator/prey ratios before making threatment decisions.
