Book excerpt: Preliminary experiments in 1968 indicated that water hyacinths and possibly other aquatic plants could be controlled by 10.6 micron laser radiation. Two effects were noted: an immediate plasmolysis directly proportional to laser energy and a secondary effect at lower levels of irradiation that resulted in death of the plant after a period of time. Studies made in 1969 indicated that split applications of laser energy were not more effective than continuous treatment. Plant count evaluations were significant at a minimum level of 0.5 joules per sqcm(J/sgcm). Histological examination of irradiated leaf tissue did not show extensive cell damage due to laser treatment. Studies made in 1970 indicated that twice-irradiated plants were affected at a level of about 70J/sqcm. (Author).

Book excerpt: Present water hyacinth control programs provide at best only short-term control, and thus are of short-term benefit as far as productivity of the environment is concerned, whereas successful biological control will provide long-term benefits to productivity, with a concomitant reduction in the use of chemical or mechanical disturbances of the environment. Once a biological control agent is established, it becomes an integral part of the environment and as such may properly be considered a self-renewable resource, and a beneficial addition to our environment. It is a hope that Neochetina eichhorniae will prove to be just that, and that it will, alone or in conjunction with other native or introduced natural enemies, bring about the alleviation of the problems caused by water hyacinth in the southeastern United States.
