Wind and Sand Damage
(Reviewed 8/07, updated 8/07)
In this Guideline:
Bean leaves and pods can be damaged by the physical action of wind and wind-blown sand. Two types of wind-induced damaged can occur. The first is long tears in leaves, which is most common during hail storms. More commonly, damage is a result of rubbing injury, which appears on leaves as shiny greenish tan areas and on pods as elongate, discolored streaks or lesions that develop into raised or bumpy spots.
High speed winds combined with blowing sand or hail can cause significant damage to bean plants, particularly those that have a tall growth habit and large leaves.
When warranted and possible, grow short compact cultivars with small leaves, and plant rows in the direction of prevailing winds to minimize swaying.
