This book was released on 1981 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of the evaluation of two species of insects for the biological control of Eurasian watermilfoil (Myriophyllum spicatum L.). One of the species is a native weevil, Litodactylus leucogaster (Marsh.), which attacks the flower spikes, and the other is an accidentally introduced European moth, Acentria nivea (Oliver), whose larvae feed on the leaves and stems. The biology of L. leucogaster was studied in detail and host-specificity tests were conducted with adults and larvae. Since it was determined to be specific to watermilfoils, it was released at Crystal River, Florida, on 22 August 1979. Two adults were captured at Crystal River in November indicating possible establishment. The pyralid moth, A. nivea, was difficult to rear in the laboratory. Since the females were active only one night, successful matings were rare in the small colony. Larval production was best in containers that were minimally disturbed. the larvae required water temperatures below 22 C for development though they could survive short periods at higher temperatures. The larvae were not specific to milfoil; however, A. nivea may still be of interest as a member of a complex of species which attack milfoil. (Author).

This book was released on 1983 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations on the effectiveness, persistence and drift of 2,4-D(Aqua-Kleen) were reviewed following 33 treatments to controlEurasian water milfoil between 1976 and 1981. These experimentsindicated that in certain locations, 2,4-D was effective inremoving nuisance weed growth for up to three years followingtreatments. Legal considerations, procedures for application andmonitoring, and technical information on 2,4-D and othertreatment methods were reviewed to guide implementation of futuretreatment programs. The major advantage of herbicide use wasthat in some sites it could be applied relatively quickly, overlarge areas, at a low cost. The major limitation of herbicidetreatments was possible conflicts with water use. Followingexperimental treatments, concentrations of 2,4-D above thedrinking water standard (0.1 mg/L) persisted in the treated areafor a maximum of 4 to 6 days. Drift at this concentration wasdetected at a maximum of 125 m from open water treatments of 12ha or less in large lakes. Low concentration of herbicide (justabove 0.001 mg/L) were observed to drift up to 2 km and, typically, persisted for less than 40 days in treatment areas. It was unlikely that well water near treatment areas could becontaminated with 2,4-D, but the potential for hydrauliccontinuity between wells and treated water should be considered. No significant detrimental effects on non-target organisms wereobserved, although agencies responsible for wildlife resourcesshould be contacted about new treatment sites.
