Ceratocystis Revisited

摘要

BACK IN THE early 1970s, when almond trunk shakers were becoming mainstream, the novelty of theconcept and the unfamiliarity of equipment operation and preharvest orchard prep led to many cases of trunk and scaffold damages and the resulting ceratocystis canker (CC) infections.Much of this could be attributed to improper equipment maintenance, clamp pressures, and insufficient dry-down of the orchards prior to shaking. As shaker tech-nuiugy mipiuveu aiiu unveisbecame more experienced, CC cases tapered off. A better understanding of irrigation cutoffs (varies with soil type, irrigation system, and growing region) also contributed much to reducing damages.
