Abstract
Results showed that extension intervention enhanced farmers’ perception of certified seedlings. However, educational extension treatment such as the distribution of posters and training with posters found to be limited evidence of a causal effect on WTP. The study found that the most common reasons for not adopting clean seeds before and after the intervention were lack of concern, inability to pay, need for information, preference for own stem, and intention to stop planting. Difference-in-difference model indicated that training with posters had interaction before and after the implementation of the intervention which decreased the price of WTP by about 500 riels. This study also noted that farmers who increased their knowledge of SLCMD decreased their WTP statistically by about 400 riels. It is suggested that facing severe diseases did not affect the acceptance of cleaned seeds. Additionally, it observed that farmers became more cautious of purchasing seeds after the training as they could use their seedlings for multiplication.
