Efficacy and timing of application of fungicides for control of citrus postbloom fruit drop
Citrus postbloom fruit drop (PFD) caused by Colletotrichum spp. occurs in several countries
in the Americas reducing yields by as much as 80%. Fungicide application is the main
strategy for PFD control. Two field trials were performed to assess the timing of applications
and another two were set up to investigate the efficacy of fungicides for PFD control in São
Paulo State, Brazil. The percentage of symptomatic flowers per branch, the number of
persistent calyces per branch, the number of fruit per branch and yield were evaluated. Four …
