Numerous studies have examined how farmers are involved and behave in the use of pesticides, but what drives farmers’ intention to diminish pesticide applications is mostly unknown. This study explored farmers’ intention to minimize pesticide use, through the theory of planned behavior (TPB) and an adjusted form of the TPB, with perceived risk of loss as an additional variable to the original model. On a scale from 1 to 5, intention to reduce pesticide use had the lowest score of all variables (2.36), indicating that most farmers did not show intention to reduce pesticide use. Only 15.2% of the farmers were willing to reduce pesticide use, while 8.3% were undecided. Moreover, 58.2% of the farmers had high levels of perceived risk of loss by the reduction of pesticide use, which explained 37.3% of farmers’ intention. From the three variables of the TPB, attitudes had the highest score (3.34), indicating slightly favorable attitudes toward pesticide reduction, while perceived behavior control had the lowest score (2.70), indicating poor control of pesticide reduction. Also, the three basic variables of the TPB were positively correlated (P < 0.01) with farmers’ intention to reduce pesticides, while a negative correlation (P < 0.01) was noted between intention to reduce pesticides and perceived risk of loss. The three basic variables of the TPB were significant predictors of intention, capturing 54.7% of the variation in farmers’ intention. Adding perceived risk of loss as a construct to the TPB improved the predictive ability of the original model. Poor control of pesticide reduction (high-perceived barriers) and high perceived risk of loss drive farmers’ intention to reduce the use of pesticides. Advancing alternative crop protection methods focusing on agro-ecology and integrated pest management should be included in the work of extension services.

许多研究检查了农民如何参与农药的使用和行为，但是驱动农民减少农药使用的意图的原因尚不清楚。这项研究通过计划行为（TPB）理论和TPB的调整形式探索了农民减少农药使用的意图，并将损失的风险视为原始模型的一个附加变量。在从1到5的等级中，减少农药使用的意愿在所有变量中得分最低（2.36），表明大多数农民没有表现出减少农药使用的意愿。只有15.2％的农民愿意减少农药的使用，而8.3％的农民仍未决定。此外，减少农药使用的农民中有58.2％的人感觉损失的风险很高，这解释了37.3％的农民的意愿。从城规会的三个变量来看，态度得分最高（3.34），表明对减少农药的态度略好，而知觉行为控制得分最低（2.70），表明对农药减少的控制不力。而且，城规会的三个基本变量是正相关的（P <0.01）与农民减少农药的意愿，而减少农药的意愿与损失风险之间存在负相关（P <0.01）。城规会的三个基本变量是意向的重要预测指标，占农民意向变化的54.7％。在TPB中增加损失的感知风险作为一种构造，可以改善原始模型的预测能力。对农药减少的控制不力（高感知的障碍）和较高的损失风险，促使农民打算减少农药的使用。推广服务的工作应包括以农业生态学和病虫害综合治理为重点的替代作物保护方法的发展。
