 Bean-10.0 Nightshade Damage

Portion for Analysis: Class Dependent


Beans and pieces of beans which have nightshade juice on the seed coat with an area of coverage and intensity equal to or greater than shown. The determination is based on the berry stain on one or both sides of the bean. Black Nightshade berries stain the bean purple during threshing and are most commonly found in Blackeye beans.




NOTE: This interpretation also pertains to beans with bag markings/ink stains on the seed coat. The discoloration appearing on larger/smaller beans should be proportional. Beans containing any amount of berry juice, bag markings, and/or ink stains on the cotyledon are damaged.
