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...

The decomposition of 2-chloro-4-ethylamino-6-isopropylamino-S-triazine (atrazine) and related s-triazine herbicides by soil microorganisms

Creator:: Duke, William B.
Abstract:: Atrazine, atratone and ametryne are asymmetric s-triazine herbicides used pre- and post-emergence on many crops. Under conditions unfavorable for microbial activity, these compounds may persist in the soil for long periods of time. This study was conducted to determine the influence of the soil microflora upon atrazine, atratone and ametryne...

The herbicide HOE 23408; soil persistence, spring wheat cultivar tolerance, and interaction with broadleaf herbicides

Creator:: Ivackovich, Branislav D.
Abstract:: HOE 23408 [ 4-(2' , 4'-dichlorophenoxy)-phenoxy-u-propionic methylester.1 is a promising new compound for control of wild oats and other grass weeds in small grains. Several factors influencing its use for this purpose were investigated. Greenhouse bioassay studies were conducted in 1975 to determine relative persistence of HOE 23408 in four...

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...
