Two years' research, 1975-76, revealed that mungbeans are attacked by 26
insects, 6 diseases, and 2 nematodes from the seedling through post harvest in
the Philippines. The present paper points out the issues behind the yield gap
between farmers fields and research fields and the implications to future
research and extension efforts. [THH]

An experiment was conducted to define the proper timing of insecticidal
treatments in relation to the growth stages of mungbeans. During the dry
season, insecticide spraying at 3+17+31+45 days after emergence (DAE) produced
the highest yield, and during the wet season two sprayings at 31+45 DAE gave
the best yield. [THH]
