Previous studies have found that the uses of the internet can increase the adoption of green technology for preventing and controlling diseases and pests among farmers. However, they do not distinguish between the effects of the different uses of the internet (with or without productive use). The Internet is a skill-biased technological progress which majority of the under-educated farmers can only use but don’t know how to make good use of. Based on the data and statistics of 2544 skilled farmers in 2019, it is found that 20.32% of them use the internet only for communication and entertainment. The adoption rate of green technology for preventing and controlling diseases and pests is just 30.95% while the adoption rate among the professional farmers is 44.55%. Logit, Probit, and LPM regression analysis have been used to analyze the statistics and the methods of double robust model IPWRA and AIPW have been used to validate the results. The findings echo one another. The result from double robust model shows that the adoption rate of green technology for preventing and controlling diseases and pests among the professional farmers increased by 6.55%, and that means the adoption rate increased 15.68%, which is statistically and economically significant.
