PROPOSAL FOR INTRODUCTION OF EFFICIENT AND EFFECTIVE TECHNIQUE FOR CONTROLLING EMBANKMENT VEGETATION WITH THE PLANT GROWTH REGULATORS FROM A CASE IN WATARASE RIVER

Abstract

Recent invasion and growth of alien plants has brought negative effects for embankment management, such as causing structural damages and impeding river inspection/embankment examine works.

To solve these problems caused by alien plants, this report focuses on the safe and effective plant growth regulators which has been improved under the revised Agricultural Chemicals Regulation Act. In addition, it proposes more efficient and effective technique for controlling embankment vegetation by using the plant growth regulators based on the on-site operation tests in Watarase River.
