Public ISBD Titre de série : Research Report Titre : Water resources technical publication: aquatic weed control studies Type de document : texte imprimé Auteurs : Otto, N. E. ; Bartley, T. R. Mention d'édition : USDI Editeur : USDI Année de publication : 1966 ISBN/ISSN/EAN : CI-10042 Note générale : Progress of various bureau of reclamation laboratory studies concerned with submersed aquatic weed problems are covered results summarized are not considered conclusive and generally require further investigation low-rate, long contract period treatment with acrolein in a flowing water situation caused a significant reduction in the total plant dry weight and vegetative propagule production of psundweeds. Weekly injury and regrowth estimates for 4 weeks following acrolein treatments describe the trends of pardweeds response to the acrolein treatments. Results of recent herbicidical evaluation tests did not reveal any compound of promise for aquatic weed control. Two formulations of endothal exhibited good algaecidal activity on filamentous green algae in laboratory tests. The phytoxicity of xylene-type aquatic herbicides is not enhanced by the use of selected additives.
