Description

This report focuses on the safe and effective plant growth regulators, which has been improved under the revised Agricultural Chemicals Regulation Act, and discusses the technique for controlling embankment vegetation with plant growth regulators, as the cost reduction effects of river maintenance by the reduction of public-works spending. In particular, the aim of this report is to solve problems caused by alien plants, which the invasion and growth of alien plants have brought the negative effects for embankment management such as obstacles to river inspection / embankment examine works and weakening of embankment function. The technique for controlling embankment vegetation with plant growth regulators was experimented in Watarase River, and the results showed improved effect against the maintenance problems, around 30% cost reduction in comparison with the existing maintenance cost, and safe to the environment. Therefore, it is thought that the technique for controlling embankment vegetation using the plant growth regulators is applicable enough for the future river embankment management.
