Integrated Management of Haricot Bean Foliage Beetle in Northeastern Ethiopia

الملخص EN

A field experiment was conducted to determine the integrated effect of planting dates, insecticides, and their interaction on the reduction of yield and yield related components of haricot bean caused by haricot bean foliage beetle damage at Sirinka Agriculture Research Center, Ethiopia.

Planting dates were normal planting (NP) and late planting (10 days after normal planting) (LP), while insecticides comprised Apron star seed dressing (A) and without insecticide (WI).

The combined analysis revealed that late planting combined with Apron star seed dressing (LPA) resulted in the highest yield (1223.7 Kg/ha).

On the other hand, normal planting date without insecticide application (NPWI) gave the lowest yield (209.6 kg/ha) and the maximum yield loss (209.6%).

The cost-benefit analysis showed that use of LPA gave by far better high net profit over control.

Thus, LPA are recommended for haricot bean foliage beetle management in northeastern Ethiopia.
