The soil persistence and crop selectivity of 3, 6-dichloropicolinic acid

Creator:: Olson, David Lloyd
Abstract:: Field studies were conducted in 1973 and 1974 to determine the soil persistence of the herbicide M-3785 (containing 0.5 lb a.e. Dowco 290 + 2.0 lb a.e. 214D/gallon). under cropping situations. Spring barley (Hordeum distichon L. 'Hannchen') was grown at Corvallis, Oregon and winter wheat (Triticum aestivum L. 'Nugaines.') was...

Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Factors influencing the herbicidal activity and persistence of isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone in soil

Creator:: Donaldson, Dean Robert
Abstract:: The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...

How Oregon farmers select and use herbicides on wheat

Creator:: Fine, Richard Ray, 1939-
Abstract:: Questionnaires were used in a survey of Oregon farmers to determine how they select and use herbicides on wheat. Farmer's decisions were evaluated on the basis of their ability to: select the proper herbicide treatment for their weed problem and to make application at the proper time. Questionnaire scores indicated...

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...

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,...
