Promotion of Sorghum Callus Growth by the s-Triazine Herbicides.
Growth-promoting action of simazine and other s-triazine herbicides was detected by the use of sorghum (Sorghum bicolor [L]. Moench) callus tissue and the chlorophyll retention test. Soil application of simazine [2-chloro-4, 6-bis(ethylamino)-s-triazine] at sublethal levels nearly doubled the growth-promoting action of sorghum root exudates. Treated plants yielded up to 26% more total protein t...
متن کاملPrediction of s-triazine components lipophilicity of total herbicides
A liquid chromatography method has been developed and validated for the determination of mathematical models for prediction of the lipophilicity of s-triazine compounds. Correlation between retention factors, RM 0 , of several s-triazine derivatives and their physico-chemical and structural properties has been studied by TLC on silica gel impregnated with paraffin oil. The research in this pape...
متن کاملDetermination of Seventeen s-Triazine Herbicides and Derivatives by High-pressure Liquid Chromatography
Mixtures of simazine, atrazine, ametryne, prometryne, deethylsimazine, deethylatrazine, hydroxysimazine, hydoxyatrazine, hydoxyprometryne, N-ethyland N-isopropylammeline, N-ethyland N-isopropylammelide, melamine, ammeline, ammelide, and cyanuric acid in aqueous solution were separated and determined in a single analysis with a detection limit of 30-400 pmol. The s-triazines were detected by a U...
متن کاملOn the removal of s-triazine herbicides from waters using commercial low-cost granular carbons
The a dsorption capacities of three low-cost granular active carbons, used in a water treat ment fa cility for the re moval of the t riazine herbicid es propazine, pro metryn and pr ometon, wa s e valuated. Kin etic studie s showed that the three carbon sa mples used could be suitable in prac tice for the trea tment of moderate contents of the herbicides in contaminated waters. The apparent ads...
متن کاملEffects of the exposure of fish to triazine herbicides.
Triazines are an important group of herbicides, which have been used extensively or selectively both in agricultural and non-agricultural areas worldwide for more than fifty years to control broadleaf and some grassy weeds. As a consequence of their massive application, they have become and remain significant environmental pollutants, especially in aquatic ecosystems. Fish are an integral part ...
