TBT and TPhT persistence in a sludged soil

Chemosphere, 2006
The persistence of tributyltin (TBT) and triphenyltin (TPhT) in soils was studied, taking into consideration the quantity of sewage sludge, TBT and TPhT concentrations in soil as well as the soil pH. The organotin compounds (OTC) were introduced into the soil via a spiked urban sludge, simulating agricultural practise. OTC speciation was achieved after

Persistence of terbuthylazine in soils

Bulletin of Environmental Contamination and Toxicology, 1994
Terbuthylazine, a non-selective herbicide developed by Ciba Geigy, is a triazine herbicide, as are simazine, terbutryn and atrazine. Terbuthylazine is a broad-spectrt~n herbicide registered for control of most annual grasses and broadleaf weeds in rubber, oil palm and cocoa plantations and in orchards as well as on non-crop land.

Persistence of Acetamiprid in Soil

Bulletin of Environmental Contamination and Toxicology, 2007
Crops, which are the main source of food for humans, are attacked by various disease causing organisms like viruses, fungi, insects, nematodes, etc. Weeds are another threat to agriculturally grown crops. It is estimated that one third of the world’s food crop is destroyed by these pests annually.

Persistence of herbicides in soil

Journal of the Science of Food and Agriculture, 1967
AbstractA survey has been made of some of the physical, chemical and biological interactions that influence the persistence and availability of herbicides applied to the soil. The most important physical interaction between herbicides and soil is considered to be sorption of the pesticide to the soil surface.

Persistence of Eimeria bovis in soil

Parasitology Research, 2013
Eimeriosis is a disease that occurs globally and often affects cattle grazing on pastures contaminated with oocysts of the pathogenic species Eimeria bovis, Eimeria zuernii or Eimeria alabamensis, respectively. Nonetheless, little is understood regarding oocyst persistence on the pasture. The study was performed in the temperate climate zone.

Persistence of Fluoroacetate and Fluoroacetamide in Soil

Nature, 1966
LABORATORY tests have shown that sodium fluoroacetate1,2 and fluoroacetamide3,4 can act as systemic insecticides, and the latter compound has been tested or used in the field for pest control (mainly against aphids) in several countries5–7. In Britain, however, following the Smarden incident, the use of these compounds as rodenticides has been severely

Persistence and biodegradation of carbaryl in soils

Journal of Environmental Science and Health, Part B, 1980
The persistence of the methylcarbamate pesticide carbaryl was studied in four soils under flooded conditions. A substantial portion of the pesticide was recovered from all soils even after 15 days of its application, with the recovery ranging from 37% in an alluvial soil to 73% in an acid sulfate soil.

Soil Persistence of Napropamide

Weed Science, 1979
The persistence of napropamide [2-(α-naphthoxy)-N,N-diethylpropionamide] applied at 2.24- and 4.48-kg/ha was studied for 2 yr at two locations in the field. Wheat (Triticum aestivumL. ‘Arthur 71′) was severely injured when sown in the fall following a spring application of napropamide.

Soil Persistence of Dinitramine

Weed Science, 1980
The effects of soil temperature, moisture, and herbicide concentration on the rate of degradation of dinitramine (N4,N4-diethyl-α,α,α-trifluoro-3,5-dinitrotoluene-2,4-diamine) were measured in clay loam and sandy loam in the laboratory. In sandy loam, the rate of degradation increased with increasing temperature.
