Arthrobacter oxydans P52 isolated from soil samples was found to degrade the phenylcarbamate herbicides phenmedipham and desmedipham cometabolically by hydrolyzing their central carbamate linkages. The phenylcarbamate hydrolase (phenmedipham hydrolase) responsible for the degradative reaction was purified to homogeneity. The enzyme was shown to be a monomer with a molecular weight of 55,000. A ...

Salvia aethiopis is an aromatic species within the Lamiaceae family, used both as a herb and ornamental plant, yield quality of which, when cultivated on commercial basis, frequently affected by weed infestation. Therefore, application herbicide often required for production this species. Considering current study, pot experiment based upon completely randomized design, with three replications,...

in order to reduce herbicide utilization, a 3-year field experiment was carried out with integration of mechanical and chemical weed control methods; in mechanical method, three types of blades (curred- bed knife, square- turn knife and sweep) were used. chemical control was done with chloridazon (wp 80%) and desmedipham (ec 15.7%) in two spraying sheme: once band sparying with 2 l h-1 & twice ...

ABSTRACT-Several herbicides are registered for selective weed control in sugar beet; however, no single chemical herbicide can control all weeds in beet fields. Frequently, two or more herbicides may have to be combined sequentially or as tank mixed to achieve adequate broad-spectrum weed control. In order to evaluate the effects of some combinations of broadleaf herbicides on sugar beet yield ...

The results of eleven experiments dealing with (1) lime application, (2) herbicides, (3) nematicides, (4) varieties, (5) fungicides, (6) sowing date and (7) yield potential, are discussed. Lime was necessary, not to create a more neutral soil reaction, but to eliminate most of the exchangeable aluminium in the soil. It was necessary to incorporate lime to a depth of 200 mm but not deeper. Cyclo...
