Suitability for cultivation and agronomic production

This variety is not very vigorous and should be moderately pruned. Its fairly early budburst exposes it to the risk of spring frosts.
Susceptibility to diseases and pests

Montils is susceptible to grey rot when the grapes reach maturity. It is however not very sensitive to wood diseases.
