Say goodbye to pesticides because there is now an effective, economical and safer way to control major insect pests of snap beans.
Through our study entitled Intercropping Studies of Snap Beans in Ifugao and Its Effects on Major Insect Pests and Yield, Elmer P. Comaad and this author have found out that intercropping snap beans with green onions, ampalaya, bell pepper and tomato effectively controls pod borer, leaf miner and bean fly.
This is because the crops are shielding each other from the impact of airborne pathogens and vectors. The insect pests are only used to the smell of their host crop if this is planted as monocrop. So when other crops are combined or intercropped with the host, the crops produce a different aroma, which gives the pests difficulty locating their host.
