Postbloom fruit drop, cased by colletotrichum acutatum, produces orange-brown lesions on flower petals, abscission of fruitlets, and formation of persistent calyces (buttons). A previously developed model that predicts the percentage of flower infection 3 to 4 days in advance based on the current number of infected flowers and rainfall for the previous 5 days was evaluated in there navel and Valencia orange groves in 1993 and in five groves each in 1994 and 1995. There was a significant (P< ou = 0.05) relationship between the predicted and observed percentages of affected flowers of the nine cases in which sufficient disease developed to warrant fungicide applications (R =0.38 to 0.86). |
