The effect of 2,4-D on the respiration rate and ethylene production of Bartlett pears and Red Delicious apples

Creator:: Fechtig, Allen David
Abstract:: After nearly 20 years of commercial use in orchards without apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy) acetic acid] was reported in 1970 to cause injury to apple and pear trees in Washington. In the early 1970's, there was widespread concern among growers, researchers, and processors in the...

The effects of N-1-Naphthylphthalamic acid on growth of yellow nutsedge and its control with N-Phosphonomethyl glycine

Creator:: Paller, Enrique C.
Abstract:: Greenhouse and growth chamber experiments were conducted with the following objectives: (a) to study the effects of N-1-naphthylphthalamic acid (naptalam) on shoot and tuber production, rhizome transformation, and growth of yellow nutsedge (Cyperus esculentus L.) plants; (b) to study the effects of N-phosphonomethyl glycine (glyphosate) on nutsedge plants at different...

Factors influencing wild oat control with N-benzoyl-N-(3,4-dichlorophenyl) alanine (SD 30053)

Creator:: Colbert, Donald Robert
Abstract:: Studies were conducted in 1969 and 1970 to evaluate the effectiveness of an experimental herbicide, SD 30053 (alanine, N-benzoyl-N-(3, 4-dichlorophenyl)-, ethyl ester), for wild oat (Avena fatua L.) control in winter cereals. The 1969 field studies showed that postemergence applications of SD 30053 were effective in controlling wild oats. Wild...

A proposed mechanism for diuron-induced phytotoxicity

Creator:: Stanger, Charles Earl, 1929-
Abstract:: Previous research has shown that specific carotenoid pigments function through oxidation-reduction reactions to protect chlorophyll from photooxidation in the presence of reduced nicotinamide adenine dinucleotide phosphate (NADP). The hypothesis that diuron (3-(3, 4- d chloropheny1)-1, 1-dimethylurea) initiates phytotoxicity by inhibition of NADPH synthesis was examined. All experiments were conducted in...
