The incidence and severity of CBS were high for all treatments, increasing with the fruit maturation. Five evaluations were carried out with 30-day intervals from mid-July to mid-November when fruits were harvested. Thus, managements with lower intervals between applications require a higher number of applications to maintain the ideal protection period. Saint Paul, Minnesota: APS Press, 2000. v. 2, cap.
