Metabolic Fate of Emamectin Benzoate in Soil
Journal of Agricultural and Food Chemistry, 1997Aerobic and anaerobic incubation of microbially active soil with [14C]MAB1a resulted in measurable evolution of 14CO2. Chromatographic and mass spectral analyses of extractable residues demonstrated the degradation of [14C]MAB1a to 8aOH-MAB1a and 8aoxo-MAB1a. The highest levels of 8aOH-MAB1a and 8aoxo-MAB1a were found at the 60-day incubation interval,

Photodegradation of Emamectin Benzoate in Aqueous Solutions
Journal of Agricultural and Food Chemistry, 1998The half-life of [14C]4‘‘-deoxy-4‘‘-(epi-methylamino)avermectin B1a (MAB1a) benzoate (1 ppm) photodegradation in buffer (pH 7), natural pond water, and sensitized buffer (1% acetone in pH 7 buffer) determined at Three Bridges, NJ (latitude ∼40° N) during the fall season under natural sunlight was 22, 7, and 1 days, respectively.

Fate of [14C]Emamectin Benzoate in Head Lettuce
Journal of Agricultural and Food Chemistry, 1995The fate of [ 14 C]emamectin benzoate in head lettuce was investigated. Two treatment groups, at a 1x (0.015 lb of active ingredient/acre) or a 5x rate, received eight weekly applications. Plants were harvested from 2 h to 10 days after the last application.

Toxicity of emamectin benzoate to mallard duck and northern bobwhite quail
Environmental Toxicology and Chemistry, 1998Abstract Nineteen- to 26-week-old mallard ducks (Anas platyrhynchos) were found to be more sensitive than northern bobwhite quail (Colinus virginianus) of the same age to single oral doses of emamectin benzoate. The resulting median lethal dose values determined for emamectin benzoate to mallard duck and northern bobwhite quail were 76 ...

Persistence and risk assessment of emamectin benzoate residues on okra fruits and soil
Environmental Technology, 2014Emamectin benzoate, a synthetic derivative of abamectin, is found effective against fruit borer and jassid in okra crops. The present studies were carried out to study the dissipation pattern of emamectin benzoate on okra and to suggest a suitable waiting period for the safety of consumers. Following three applications of emamectin benzoate (Proclaim 5

Dissipation and Residues of Emamectin Benzoate Study in Paddy Under Field Conditions
Bulletin of Environmental Contamination and Toxicology, 2011The objective of this experiment was not only to provide a simple residue analytical method to evaluate the safe application rate of Emamectin Benzoate for paddy crops but also to give a suitable recommended dosage in paddy crops. Paddy samples were detected using HPLC-MS/MS.

Toxic effects of emamectin benzoate on the liver of Labeo rohita.
BIOINFOLET - A Quarterly Journal of Life SciencesFreshwater fish Labeo rohita were exposed to two different concentrations of insecticide Emamectin Benzoate (EB). The 96 hour LC0 and LC50 of EB for L. rohita were determined to be 0.58 ppm and 0.83 ppm respectively. Histological alterations were characterized by haemorrhage, necrosis, pyknotic nuclei and degeneration of hepatocytes, whereas control ...
