Degradation of biochanin A in soil
Chemoecology, 2010Degradation of biochanin A, 400 μg (1.41 μmol) per gram of dry soil, was studied and the initial degradation products, dihydrobiochanin A, pratensein and genistein were identified and quantified. The maximum concentrations of these compounds were determined as 166 pmol/g dry soil after 2 days of incubation, 175 pmol/g dry soil after 1 day and 1,236 ...

Degradation of monocrotophos in soils
Chemosphere, 2006The degradation of a widely used organophosphorus insecticide, monocrotophos (dimethyl (E)-1-methyl-2-methylcarbamoyl vinyl phosphate) in two Indian agricultural soils at two concentration levels, 10 and 100 microg g(-1) soil under aerobic conditions at 60% water-holding capacity at 28+/-4 degrees C was studied in a laboratory.

Agricultural Soil Degradation in Croatia
2022Croatian agriculture has a small impact on the country’s economy (around 4% of the Croatian Gross Domestic Product), but agricultural activities affect agricultural land and reduce quality and productivity. The types of land degradation are not distributed equally in the territory, considering an environmental diversity between the Mediterranean ...

Degradation and Adsorption of Fosthiazate in Soil
Journal of Agricultural and Food Chemistry, 2004Adsorption and degradation behavior of a pesticide in soil has a strong effect on its environmental fate as well as efficacy for pest control. Fosthiazate is an organophosphate compound that is currently under development as a nonfumigant nematicide. In this study, we evaluated adsorption and degradation kinetics of fosthiazate in three U.S. soils with

Degradation kinetics of glucosinolates in soil
Environmental Toxicology and Chemistry, 2006Abstract Glucosinolates are compounds produced by all cruciferous plants. They can be hydrolyzed to several biologically active compounds and, as such, may serve as naturally produced pesticides. To optimize the pesticidal (biofumigation) effect and to assess the risk of glucosinolate leaching and spread in the environment, the ...

Soil microbial degradation of Aldrin
Life Sciences, 1968Abstract The degradation of aldrin by soil microorganisms has been investigated. Ninety-two pure cultures were screened in vitro for aldrin degrading activity. The majority showed some capacity for converting aldrin to dieldrin. Among the fungi, Trichoderma were the most active, followed by Fusarium and Penicillium ...

Degradation of Dimethoate in Chrysanthemums and Soil
Bulletin of Environmental Contamination and Toxicology, 1997Chrysanthemum (Chrysanthemum Morifolium Tzvel) is an important medical herb that is widely planted in China. It can not only cure some diseases as a traditional medicine but may be a useful health protective ingredient. It is usually processed into dry flower or health beverage to go on the market.

Dieldrin: Degradation by Soil Microorganisms
Science, 1967An attempt was made to discover microorganisms that degrade dieldrin, an extremely stable chlorinated hydrocarbon insecticide. Examination of more than 500 isolates from soil that had been heavily contaminated with various insecticides revealed the existence of a few microbes that are very active in degrading this compound to various metabolites.

Enantioselective degradation of warfarin in soils
Chirality, 2011AbstractEnvironmental enantioselectivity information is important to fate assessment of chiral contaminants. Warfarin, a rodenticide and prescription medicine, is a chiral chemical but used in racemic form. Little is known about its enantioselective behavior in the environment.

Degradation of carbaryl by soil microorganisms
Archives of Environmental Contamination and Toxicology, 1977Four days after carbaryl-naphthyl-1-14C was mixed with soil from a field treated 6 months previously with 4 lb/A of the same insecticide, only 28% of the radiocarbon remained. Approximately 90% remained in soils with no history of pesticide applications.
