Wildlife toxicity studies with oxamyl

Environmental Toxicology and Chemistry, 1982
AbstractThe acute oral LD50 of oxamyl in bobwhite (Colinus virginianus), mallards (Anas platyrhnchos) and Japanese quail (Coturnix c. japonica) is 9.4, 2.6 and 4.3 mg/kg BW, respectively. The eight-day dietary LC50 in bobwhite and mallards is 54 and 369 ppm, respectively.

Acute Toxic Effects of Oxamyl in the Rat

Toxicological Sciences, 1992
The effects of single acute oral doses of 1, 2.1, and 3.5 mg/kg oxamyl (a carbamate insecticide) on selected biochemical parameters in male Sprague-Dawley rats were investigated. The animals exhibited significantly decreased weight gain when compared to control animals.

Distribution and persistence of oxamyl in oxamyl-treated seed potatoes and in plants grown from oxamyl-treated seed potatoes

Journal of Agricultural and Food Chemistry, 1990
A direct linear relationship between oxamyl concentration of treatment solutions and oxamyl deposit on soaked potato seed tubers (cv. Russett Burbank) was observed. Increasing the duration of soaking from 1 to 40 min had no effects on oxamyl deposit. No decrease in the oxamyl concentration of the treatment solutions was observed after the tubers were ...

Degradation and metabolism of Oxamyl and phenamiphos in soils

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 1986
Abstract Degradation and metabolism of the nonvolatile nematicides‐insecticides [14C]oxamyl and [14C]phenamiphos (P) were investigated using three Southeastern U.S. soils (Arredondo sand, Cecil sandy loam and Grenada silt loam). Oxamyl in moist soils (10 and 33 kPa) was rapidly mineralized to CO2, with N,N‐dimethyl‐2‐(methylthio)acetamide oxime (DMAO ...

Adsorption and interaction of oxamyl with kaolinites

Proceedings / Indian Academy of Sciences, 1980
The adsorptive behaviour of oxamyl with H-, Na- and Ca-kaolinites was studied. The effect of time on adsorption showed that the process was diffusion controlled. Kinetic studies showed that reaction was of first order. Maximum adsorption occurred at pH 6·5 (in the vicinity of pK value).

Acute toxicity studies with oxamyl

Fundamental and Applied Toxicology, 1986
The acute toxicity of oxamyl, an insecticide and nematicide, has been evaluated to establish proper handling guides. The material is highly toxic when given as a single oral dose; its LD50 is in fasted rats 2.5 to 3.1 mg/kg, 2.3 to 3.3 mg/kg in fasted mice, and 7 mg/kg in guinea pigs. A beagle dog given 30 mg/kg died, while 15 mg/kg was not lethal.

Metabolism of oxamyl in mice and twospotted spider mites

Archives of Environmental Contamination and Toxicology, 1979
The metabolic fate of oxamyl was examined in mice and twospotted spider mites,Tetranychus urticae Koch. Mice treated intraperitoneally with oxamyl-14C eliminated 96.4% of the dose in the urine (88.7%) and feces (7.7%) by 96 hr; 75.7% of the dose was eliminated during the initial 6 hr. Organosoluble urinary radioactive material ranged from 24.6% at 6 hr

Natural phillipsite as a matrix for a slow-release formulation of oxamyl

Environmental Pollution, 1995
The performance of phillipsite as a matrix for slow-release formulation of oxamyl [N,N-dimethyl-2-methylcarbamoyl-oxymino-2-(methylthio)acetamide] was tested. The adsorption kinetics followed a first-order law, and the adsorption isotherm fitted well in a two-surface Langmuir model, suggesting a double mechanism of interaction between oxamyl and the ...

Solar photocatalytic mineralization of commercial pesticides: Oxamyl

Solar Energy Materials and Solar Cells, 2000
Abstract One of the most important sources of high-pesticide-content polluted waters results from the rinsing of pesticide containers. In this paper, a pre-industrial solar TiO 2 -photocatalytic treatment is used to prevent such pollution of continental waters and a commercial pesticide (Vydate L®, 24% oxamyl) is used as a model to demonstrate the ...

Chronic Toxicity, Reproductive, and Teratogenic Studies with Oxamyl

Toxicological Sciences, 1986
Oxamyl (methylN',N'-dimethyl-N-[(methylcarbamoyl)oxy]-1-thiooxam imidate; CAS 23135-22-0) was tested for oral toxicity in the rat and dog (90-day and 2-year feeding studies) and in the mouse (2-year feeding study). Teratogenic potential was evaluated in the rat and rabbit and functional reproductive capacity was studied in the rat in a one- and a three-
