Effect of two methylcarbamates on the toxiciity of isopropyl m-chlorocarbanilate (chlorpropham) to safflower (Carthamus tinctorius L.) and common buckwheat (Fagopyrum esculentum Moench.)

Creator:: Kirkland, Kenneth
Abstract:: Addition of the methylcarbamate compounds p-chlorophenyl N-methylcarbamate (PPG-124) and 1-naphthyl N-methylcarbamate (carbaryl) to various herbicides has resulted in reduced rates of degradation. Carbaryl affects the degradation of certain herbicides in both plants and soils while PPG-124 has only been demonstrated to affect degradation in soils. Both these materials are effective...

Stimulation of plant growth by sub-lethal concentrations of herbicides

Creator:: Wiedman, Steven John
Abstract:: Studies were conducted to determine the extent and nature of sub-lethal effects of herbicides on plant growth. At least one herbicide from each major chemical class of herbicides was evaluated under greenhouse conditions. Oat plants were grown in sand culture to eliminate soil interferences. Herbicides were applied pre-emergence in nutrient...

Tactics for enhancing conservation biological control of twospotted spider mites, Tetranychus urticae Koch, in Pacific Northwest hop yards

Creator:: Woods, Joanna L.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a worldwide pest of numerous agronomic and horticultural plants. Conservation biological control of this pest can be unreliable due to asynchrony of natural enemies and certain horticultural practices that have a direct or indirect affect on natural enemies and the...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...
