The Knowledge Evaluation of Kaset Tambon, Changwat Phitsanulok on Brown Plant hopper (BPH) Prevention and Elimination.

Abstract

The objectives of this research are: (1) to evaluate knowledge of Kaset Tambon, Changwat Phitsanulok on prevention and elimination of brown plant hoppers (BPHS); (2) to study the association among social variables and level of Knowledge; and (3) to study the appropriate methods of knowledge transfer. Population are seventy-seven or 81.9 percent of Kaset Tambon. Statistics include percentage, mean, and multiple regression analysis for testing hypotheses. Results illustrate that 51.4 percent of Kaset Tambon gain 75 percent of scores on BPH prevention and elimination. Results of Knowledge evaluation indicate that Kaset Tambon should acquire more knowledge and skills on the topics of the utilization of chemical substances to eliminate BPHs, principles and methods to grow BPH-resistance rice varieties, methods to prevent BPHs, survey BPHs in the rive fields, conservation of natural enemies of BPHs, and environmental conservation concerns towards prevention of BPHs. Findings on the hypotheses testing among the association of social variables and level of knowledge show that Kaset Tambon with high scores are positively associated with their level of education. The common variances in scores on BPH prevention and elimination can be accounted for by knowing the education level of Kaset Tambon 7.94 percent. Results of the knowledge transfer methods needed by more than 90 percent of Kaset Tambon are: handbooks, field trips, lecture, movies, leaflets, slides, exhibition, posters, group discussion, short course training, video tapes, demonstration plots. face-to-face demonstration, and newspapers. Results of this research will be beneficial to the Provincial Agricultural Extension Office, Phitsanulok and The 3rd Plant Protection Unit in transferring knowledge by taking Kaset Tambon’s level of education and their preferred methods into account.
