Susceptibility of Immature and Mature Sweet and Sour Cherries to Monilinia fructicola

Abstract

Fruits of Vista and Bing sweet cherries and Montmorency sour cherry were harvested at weekly intervals between shuck fall and full maturity in 1986 and 1987.(...)Host resistance rose with the onset of pit hardening but decreased 3 wk before maturity, coinciding with yellowing and reddening of the epidermal tissue. Fungicide protection against brown rot appears warranted at shuck fall and before harvest for both sweet and sour cherries
