Management and Control:

There are several herbicides that will selectively control Adzuki Beans in non-legume crops. Generally, they will not persist in the environment without intervention and will disappear under grazing.
Helicoverpa cause significant damage in most areas. Etiella causes damage in inland NSW and Maruca Pod Borer in Queensland and coastal NSW. Green Vegetable Bug (Nezara species), Riptortus species and Mirperus species also affect Adzuki beans.

Eradication strategies:

Usually none are required.

Helicoverpa cause significant damage in most areas. Etiella causes damage in inland NSW and Maruca Pod Borer in Queensland and coastal NSW. Green Vegetable Bug (Nezara species), Riptortus species and Mirperus species also affect Adzuki beans.
