Inheritance of resistance to barley yellow dwarf virus disease in barley

Creator:: Sieveking, William Earl, 1932-
Abstract:: Studies were conducted on artificially infected susceptible and resistant barley varieties in an attempt to determine the effect of barley yellow dwarf virus on the growth and development of these plants. A resistant and a susceptible variety were infected at four stages of growth and harvested at two stages. Roots,...

The influence of herbicides, phosphorus fertilization, and mechanical and chemical seedbed preparation on the establishment of alfalfa (Medicago sativa L.) and birdsfoot trefoil (Lotus conrniculatus L.)

Creator:: Valdes Lamar, Ramon
Abstract:: Initial establishment of legume forage crops is of prime importance in determining future forage and seed production. The objective of this study was to determine the influence of herbicides, phosphorus fertilization, and seedbed preparation on the establishment of alfalfa and birdsfoot trefoil. Experiments were designed to study the influence of...

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...

Factors influencing the herbicidal activity of dimethyl 2,3,5,6-tetrachloroterephthalate

Creator:: McKinley, James Raleigh
Abstract:: Studies were conducted to determine the site of DCPA toxicity on annual ryegrass. This was done by means of a technique which used pyrex tubing and a vapor barrier to separate exposure of coleoptile and roots of emerging grass seedlings to various concentrations of DCPA. Coleoptiles that emerged through treated...

The influence of chemical and biochemical properties on the herbicidal efficiency of 3-cyclohexyl-5, 6-trimethylene uracil and 2-bromo-6'T-butyl-o-acetotoluidide

Creator:: Mackenzie, John William
Abstract:: Application of herbicides to the soil has become an important factor in the production of row crops. Economic production of sugar beet (Beta vulgaris), an important row crop, requires efficient methods of weed control. Two experimental herbicides, 3-cyclohexyl-5,6-trimethylene uracil (DP634) and 2-bromo-6't-butyl-o-acetotoluidide (CP32179), had shown promise in sugar beet screening...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

Foliage applications of terbacil to peppermint (Mentha piperita) and several weed species

Creator:: Radosevich, Steven R.
Abstract:: Several studies were conducted to determine the feasibility of using terbacil (3-tert-butyl-5-chloro-6-methyluracil) postemergence to weeds and peppermint (Mentha piperita L.). Three nonionic surfactants, four nonphytotoxic oils, and a liquid fertilizer were each combined with 0.5 lb ai/A terbacil in 35 gallons of water per acre. Weed species tested include: redroot...

Some herbicidal properties of 2-chloro 2', 6'-diethyl - N - (methoxymethyl) acetanilide

Creator:: Grandal, Osvaldo Trivelli
Abstract:: Studies were conducted to determine the site of 2-chloro 2', 6'-diethyl-N-(methoxymethyl) acetanilide (CP 50144) toxicity on barnyardgrass (Echinocloa crusgalli (L.) (Beauv.). This was done by means of a technique which used separate layers of treated soil to expose differentially the roots and/or the shoots of barnyardgrass seedlings. Coleoptiles that emerged...
