comment: Observed by general growth conditions in relation to standard resistant and susceptible checks. Since some soil problems are very heterogeneous in the field, several replications may be needed to obtain precise reading. Leaf is counted as discolored or dead if more than half of its area is discolored or dead.

Amounts of anthocyanin produced depend on stored sugar and sunlight. The more stored sugar in the leaf and brighter the autumn days, the more intense red. Anthocyanin production also increases as phosphates move out of the leaves; the lack of phosphates in young leaves can also lead to the production of anthocyanin.
