Mixture toxicity of similarand dissimilar-acting toxicants can be predicted by the models concentration addition (CA) and independent action (IA) using single substance toxicity data. Knowledge of the toxicants mode of action is thus required in order to use the models. In order to test the predictive capability of the models, we conducted Daphnia magna 48 h immobilization experiments with thre...

An experiment was carried out to evaluate different entomopathogenic fungi against chrysanthemum aphid, Macrosiphoniella sanborni (Gillette) under laboratory conditions at Biocontrol Laboratory, N.M. College of Agriculture, Navsari Agricultural University, during 2019-20 and 2021-21. The pooled mean corrected percent mortality revealed that among all the tested 4g/L, Verticillium lecanii found ...

House flies were collected from dairies across New York state and the levels of resistance to seven insecticides were measured using standard laboratory assays with three to five diagnostic concentrations. The highest levels of resistance were found for tetrachlorvinphos, permethrin and cyfluthrin. Although levels of resistance to methomyl were somewhat lower, they were among the highest ever r...

Red whitefly fungus, Aschersonia aleyrodis (Webber) is a fungal pathogen of nymphs blackfly, Aleurocanthus woglumi (Ashby) and whitefly, Dialeurodes citri (Ashmead) on the citrus plant. It used as promising biological control agent. In present study, attempts have been made to check efficacy A. biopesticides for management blackfly under laboratory condition. Probit analysis LC50 values 2nd ins...

A multi pesticide residues analysis was carried out for farmgate samples of okra fruits from four markets places of Meerut region. The okra fruits samples were analyzed for monocrotophos, chlorpyriphos, dimethoate. Okra vegetable was analyzed for pesticide residues using multiresidue analysis by GLC. It was observed that 39.0% of the samples were contaminated residues below MRL three pesticides...

The comparative metabolism of the enantiomers of cyclo phosphamide and of the racemate has been studied in humans. Four patients were each given, sequentially, the racemate, the (+)-enantiomer, and its (-)-antipode. The plasma levels of parent drug and the urinary output (24 hr) of unchanged drug and of two enzymatically produced metabolites, 4-ketocyclophosphamide and carboxyphosphamide, were ...
