The reproduction and mode of spread of sago pondweed (Potamogeton pectinatus L.) in irrigation system

Creator:: Ogg, Alex G.
Abstract:: Nine experiments were conducted during 1964 and 1965 to study the methods of reproduction and mode of spread of sago pondweed (Potamogeton pectinatus) in irrigation systems. Frequent treatments of sago pondweed foliage with aromatic solvent greatly reduced the number of tubers in the substratum of an irrigation canal. However, complete...

Chemical control of Elodea densa Planch. and other submersed aquatic plants as influenced by several environmental factors

Creator:: Mackenzie, John William, 1939-
Abstract:: Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1] heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate. Studies were conducted in coastal lakes of Oregon infested with E. densa. Dichlobenil (2, 6 dichlorobenzonitrile)...

The physiological effects and fate of dichlobenil (2,6-dichlorobenzonitrile) in an aquatic environment

Creator:: Ogg, Alex Grant, 1941-
Abstract:: The amounts of residual dichlobenil (2,6-dichlorobenzonitrile) in water and hydrosoil were compared periodically following application of the wettable powder and granular formulations of the herbicide to separate ponds at ten pounds of active ingredient per surface acre {0.6 ppmw (parts per million by weight) }. Dichlobenil was measured by electroncapture...

Biology of mudplantain (Heteranthera reniformis Ruiz et Pavon) and its control in flooded rice

Creator:: Gabela, Francisco Jose A.
Abstract:: In CIAT, Centro Internacional de Agricultura Tropical, located in Palmira, Colombia, a series of experiments were conducted to study the biology and control of mudplantain (Heteranthera reniformis Ruiz et Pavon), a member of Pontederiaceae family. Mudplantain is a perennial aquatic plant which reproduces by both seeds and stolons. It is...

Cereal residue effects on weeds and cucumbers

Creator:: Peachey, Ronald Edward
Abstract:: Cereal residues suppress the development of small seeded, summer annual weeds. The focus of this study was to determine whether cereal residues can be used to suppress weeds in cucumber production systems in the Pacific Northwest. In the first of three experiments, cereal residues of fall-planted, spring-killed cover crops suppressed...
