Persistence of triazine herbicides in soils
1970Although phytotoxic residues of the triazine herbicides are objectionable when, in some soils and under some environmental conditions, sensitive plants are injured the season after application, residual activity is essential for weed control and soil sterilization.

Metribuzin Persistence in Soil
Weed Science, 1977The persistence of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazine-5(4H)-one] in several soils from the lower alluvial floodplain of the Mississippi River was studied in the greenhouse and laboratory using bioassay and gas chromatographic methods of residue detection.

Adsorption, desorption and persistence of fomesafen in soil
Pest Management Science, 2018AbstractBACKGROUNDFomesafen provides control of glyphosate‐resistant Palmer amaranth in cotton but frequent seedling injury has been reported. This study evaluated soil adsorption, desorption, and field persistence of fomesafen.RESULTSThe Freundlich distribution coefficient (Kf) for fomesafen on seven US soils varied from 1.30 to 9.28 µg1–1/n g−1 mL1/n.

Persistence of herbicides in soil
Crops & Soils, 2016While it is desirable for the chemicals to control weeds during the season of application, it is not desirable for them to persist and affect subsequent crop growth. Factors that determine the length of time herbicides persist fall into three categories: soil factors, climatic conditions, and herbicidal properties.

Mineralogical Magazine, 1998
There is general agreement that in many soils some C compounds persist for centuries and perhaps millenia, particularly deep in the soil profile. Various chemistries and mechanisms of stabilization of C compounds have been proposed to explain their longevity in soils.

The fate and persistence of polychlorinated biphenyls in soil
Journal of Environmental Monitoring, 1999The fate and persistence of PCBs 28, 52, 101, 138, and 180 artificially introduced into three soils was studied under a variety of field conditions for up to 415 d following initial contamination. A relationship was detected between ln Koa (octanol/air partition coefficient) and the experimentally observed first-order loss rate constant that was ...

Persistence of chlorpyrifos in a mineral and an organic soil
Journal of Environmental Science and Health, Part B, 1980Chlorpyrifos (Lorsban emulsifiable concentrate) was applied at 3.4 kg AI/ha and incorporated into sand and muck soil contained in small field plots. Soil samples were taken at intervals over 2 yr. Radishes and carrots, seeded yearly, served as indicator crops for absorption of insecticide residues.

Persistence of Chlorinated Hydrocarbon Insecticides in Soils
Science, 1967The percentages of technical aldrin, chlordane, endrin, heptachlor, Dilan, isodrin, BHC, and toxaphene remaining in Congaree sandy loam soil after 14, years were 40, 40, 41, 16, 23, 15, 10, and 45, respectively; those of purified aldrin and technical dieldrin after 15 years were 28 and 31, respectively; and the percentage of technical DDT in three ...

Persistence of chlorfenvinphos in soils
Pesticide Science, 1975AbstractThe persistence and behaviour of chlorfenvinphos, an organophosphorus insecticide, was studied on different soils. On a peaty soil the insecticide was only very slowly degraded, there being 70% of the applied dose remaining after 21 weeks and 30% after nearly 12 months. On the sandy soils, however, persistence was much shorter; between 3 and 15%

Movement and persistence of aldicarb in certain soils
Archives of Environmental Contamination and Toxicology, 1977When the rate of movement and the persistence of aldicarb in 4 types of soils were investigated in laboratory and field studies some leaching was detected in coarse sand; however, leaching was quite limited in clay loam and muck soils. These data indicated that aldicarb degraded quite rapidly in the selected soils and most of the applied radioactivity ...
