The objectives of this study were: (1) to compare the level of Knowledge Attitude and Practice (KAP) on the Brown Plant Hopper (BPH) control management technology between the farmers with low and high socio-economic status (SES) in the Muda Agricultural Development Authority (MADA) area before and after the Strategic Extension Campaign (SEC); (2) to determine the change in KAP-gaps on the BPH control management technology among those farmers before and after the SEC; (3) to determine the relationship between farmer's characteristics and social activities, and the KAP-level before the SEC; (4) to determine the relationship between farmer's characteristics, social activities and multi-media factors in the SEC and the KAP-level after the SEC; and (5) to predict the KAP-level based on the KAP-equation of low and high-SES farmers in the MADA area, Malaysia. The findings revealed that KAP-level of both low and high-SES farmers on the technology of BPH control management had increased after the multi-media campaign. However, the multi-media approach of SEC had narrowed the KAP-gaps of these farmers. It was found that, therefore the degree of equality with regards to the KAP-level in the Muda Irrigation Scheme area had increased.
