ABSTRACT
Risks to human health and the environment owing to pesticide usage have arisen interest, increasing the demand for reducing pesticide consumption used on golf courses. However, standard guidelines or manuals for reducing pesticide usage on golf courses in Korea are lacking. Herein, the trends of pesticides on golf courses were investigated, and the optimal pesticide usage plan was proposed for continuous pesticide reduction. In 2019, there were 539 golf courses in Korea. With the increasing number of golf courses in 2010–2019, pesticide usage increased continuously. Fungicides accounted for more than half the pesticides used, followed by insecticides and herbicides. Except for golf courses that do not employ chemical pesticides, pesticide usage per unit area varied in the range of 0.02–65.81 kg ha−1 (average of 6.97 kg ha−1). In the US, best management practices and integrated pest management (IPM) have been stipulated and are operational in each state for pesticide management in golf courses, recognizing chemical pesticide usage to be the last approach for pest control and turf health maintenance. Considering that Korea globally ranks 10th in the number of golf facilities and courses, the establishment of IPM practices suitable for domestic conditions is essential.
