Abstract

Reduction of the environmental impact of the chemicals used in industrial activity has become important, and as an example of that, environmentally friendly agriculture is being promoted as a part of agricultural environmental policy. The active ingredient application frequency is used as an indicator of the reduced environmental influence of agricultural chemicals, but it is not clear whether there has been an actual reduction in environmental impact. The purpose of this study was to examine which indicator is preferable for the environmental management of farms. We analyzed six kinds of environmental indicators and found that the correlation between the risk score of agricultural technology for pesticide use (RST) and other indicators is small. The use of a simpler indicator showed that environmental impact was not necessarily reduced. When we analyzed the potential influence on the environment according to the agricultural chemicals usage, we found it necessary to change the means of each kind of vegetable to determine the agricultural chemicals environmental impact reduction. The advantages of the use of RST instead of the chemicals application frequency are as follows: (1) it is possible to evaluate the environmental performance of the entire management by examining two or more sections and to compare the environmental performance with past management, (2) it is effective for the development of agrotechnology, (3) the planning process for agricultural chemicals application can be introduced into the control points, and the RST indicator can be used as the environmental management indicator of good agricultural practice (GAP), (4) environmental information can be presented on the commodity label for the agricultural producer.
