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...

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...

The influence of magnesium on the toxicity of atrazine

Creator:: Brenchley, Ronald Glenn
Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post emergence for weed control in many crops. Triazine herbicides have been used in the Pacific-Northwest for weed control in orchard crops. Under certain conditions where trees were grown in nutrient deficient areas, it was noted that toxic symptoms due to...

Microbial degradation of atrazine in soils

Creator:: Skipper, H. D. (Horace D.)
Abstract:: Atrazine is an asymmetrical s-triazine herbicide used pre- and post-emergence for the control of weeds in many crops. Under conditions considered unfavorable for microbial activity, atrazine may persist in soils for extended periods of time. However, the significance of chemical versus microbial degradation is not known. This study was conducted...

Herbicidal effectiveness of trifluralin as influenced by methods of incorporation into the soil and depth of weed seed germination

Creator:: Gargano, Don Richard
Abstract:: This study was conducted to compare the effectiveness of four methods of incorporating the herbicide trifluralin into the soil, and to determine the interaction between depth of incorporation of trifluralin and depth of weed seed germination. Field experiments on green and dry peas were established in Oregon and Idaho. Trifluralin,...
