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...

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...

The effects of CIPC vapors on dodder (Cuscuta spp.) seedlings

Creator:: Slater, Clarence Harold
Abstract:: The use of CIPC (isopropyl N-(3-chlorophenyl) carbamate) to control dodder (Cuscuta spp.) in alfalfa is an established practice. A rate of six pounds per acre applied to moist soil has given good dodder control lasting from four to six weeks. The purpose of this study was to determine the effect...

Effect of chlorpropham on vegetative and reproductive development in chewings fescue (Festuca rubra L. subsp. commutata Gaud.)

Creator:: Akobundu, I. O.
Abstract:: Experiments were conducted under field and greenhouse conditions to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate) on vegetative and reproductive development in Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to determine the time of induction and initiation under natural conditions. Chewings fescue was found to be very susceptible...

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...

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...
