Enzyme-linked immunosorbent assays for the sensitive analysis of 2,4-dinitroaniline and 2,6-dinitroaniline in water and soil

Analytical and Bioanalytical Chemistry, 2008
The development and characterization of one rat monoclonal antibody (mAb) for 2,4-dinitroaniline and of two rat mAbs for 2,6-dinitroaniline are described. With the immunization of rats with 2,4,6-trinitrophenyl-glycylglycine-keyhole limpet hemocyanine (KLH) conjugate one mAb (PK 5H6) has been developed and formatted into a competitive enzyme-linked ...

Molecular structures of dinitroanilines and trinitroanilines

Computers & Chemistry, 1999
Abstract The molecular structures of six positional dinitroaniline isomers and six positional trinitroaniline isomers were calculated by a density functional theory of the Becke’s three-parameter hybrid (B3LYP) method with 6-31G* basis set. Calculations found that deformations of the phenyl ring and distortions of the nitro and amino groups with the ...

Abiotic reduction of dinitroaniline herbicides

Water Research, 2003
The importance of abiotic reductive transformations as a sink for four dinitroaniline herbicides (trifluralin, pendimethalin, nitralin, and isopropalin) has been evaluated. Using reductants representative of abiotic reductants found in natural systems, the results of this study indicate that nitro groups present on the dinitroaniline herbicides can be ...

Persistence of Dinitroaniline Herbicides in Soil

Weed Science, 1979
An oat (Avena sativaL. ‘Dal’) primary root bioassay procedure was used to study the persistence of eight dinitroaniline herbicides in soil. Sensitivity of the bioassay to the herbicides depended on the length of time roots were exposed to the herbicide treatments. Root inhibition increased with time of exposure.

Dinitroaniline herbicide resistance and the microtubule cytoskeleton

Trends in Plant Science, 1999
Dinitroaniline herbicides have been used for pre-emergence weed control for the past 25 years in cotton, soybean, wheat and oilseed crops. Considering their long persistence and extensive use, resistance to dinitroanilines is fairly rare. However, the most widespread dinitroaniline-resistant weeds, the highly resistant (R) and the intermediate (I ...

Dinitroaniline in Kabachnik–Fields Reaction

Phosphorus, Sulfur, and Silicon and the Related Elements, 2011
Abstract Simple conditions for the Kabachnik–Fields reaction of 2,4-dinitroaniline with arylaldehydes and triphenyl phosphite were found. Several diphenyl N-2,4-dinitrophenylaminobenzylphosphonates have been synthesized.

Soil Degradation of Three Dinitroanilines

Weed Science, 1977
These studies were conducted in the laboratory on two soils at two temperatures to define the rate of degradation and the associated rate law for trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine), benefin (N-butyl-N-ethyl-α,α,α-trifluoro-2,6-dinitro-p-toluidine), and 2,6-dinitro-N-(3-pentyl)-α,α,α-trifluoro-p-toluidine (hereafter ...

Dinitroaniline Herbicides in Soils

Journal of Environmental Quality, 1976
AbstractThe behavior and fate of dinitroaniline herbicides in the soil environment is reviewed. This rapidly expanding class of herbicides is used particularly for pre‐emergence control of annual grasses and small‐seeded broadleaf weeds in cotton (Gossvpium hirsutum L.), soybeans [Glycine max (L.) Merr.], and peanuts (Arachis hypogaea L.).

Volatility of Eleven Dinitroaniline Herbicides

Weed Science, 1976
Vapors of 11 dinitroaniline herbicides from soil were trapped in a Florisil column under controlled laboratory conditions for a 3-hr period. No vapor losses of nitralin [4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline] and oryzalin (3,5-dinitro-N4,N4-dipropylsulfanilamide) were detected at the highest temperature, 50 C, from moist Lakeland sand with

Behavior of Dinitroaniline Herbicides in Plants

Weed Technology, 1989
Dinitroaniline herbicides are absorbed readily by roots and emerging shoots, but shoot exposure is more phytotoxic. Translocation within the plant varies by specific herbicide but commonly is minor. Dinitroaniline herbicides injure plants by binding to tubulin, a dimer protein in the ceil that polymerizes to form microtubules (MTs).
