Replacing bud failure trees
The preceding article documents yield reductions in Nonpareil almond due to bud failure (BF). Since the yield data indicate crop reductions could potentially result in economic losses to almond growers, this study was developed to assist orchard managers in deciding what action to take when faced with BF. Three courses of action were evaluated: to maintain the BF trees, to graft, or to replant. Other alternatives, such as interplanting, are available in special cases but were not included in the study. The authors assume that normal non-BF trees will be obtained by grafting or replanting, and that a pathogen is not involved. The probability of meeting these assumptions is outlined in the previous articles.
