Mode of action, crop selectivity, and soil relations of the sulfonylurea herbicides†
The sulfonylurea herbicides are characterized by broad-spectrum weed control at very low use rates (c. 2–75 g ha−1), good crop selectivity, and very low acute and chronic animal toxicity. This class
Recent Advances in Sulfonylurea Herbicides
The sulfonylurea herbicides were discovered in 1975 and immediately set a new standard for chemical weed control. The subsequent worldwide development effort has led to the commercialization of 18
Degradation of Thifensulfuron Methyl in Soil: Role of Microbial Carboxyesterase Activity
Thifensulfuron methyl [methyl 3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate] degrades rapidly in diverse nonsterile agricultural soils. The
Indoleacetaldehyde Reductase of Cucumis sativus
The occurrence of multiple IAAld reductases, each specific for a particular pyridine nucleotide, distinguishable with respect to several properties is suggested, supporting the view that the rate of auxin biosynthesis is subject to regulation.
Degradation of Chlorsulfuron by Soil Microorganisms
Degradation of chlorsulfuron {2-chloro-N- (((4- methoxy- 6- methyl-1,3 ,5 -triazin-yl)amino) carbonyl) benzene- sulfonamide} in acidic and alkaline soils was evaluated using plant bioassay and
Basis of selectivity of the herbicide rimsulfuron in maize.
The basis of maize tolerance to rimsulfuron is rapid metabolic inactivation, which is a good correlation between the rate of metabolism of the herbicide and plant tolerance.
Ethametsulfuron Methyl Metabolism and Crop Selectivity in Spring Oilseed Rape (Brassica napus L.)
The ability of oilseed rape to rapidly metabolize ethametsulfuron methyl accounts for its tolerance to this herbicide and, along with growth dilution, contributes to an extremely low residue lever 60 days after treatment.
Isolation of a stable enzyme.14CO2.Mg2+.carboxyarabinitol bisphosphate complex with ribulosebisphosphate carboxylase from Chromatium vinosum
Higher plant-type ribulosebisphoshate carboxylase from Chromatium vinosum formed a stable, nonexchangeable complex with activator 14CO2 in the presence of Mg2+ and 2-carboxyarabinitol bisphosphate,
