Nitroguanidine (NG) and its degradation product nitrosoguanidine (NSG) were evaluated for their mutagenic potential by using Drosophila melanogaster sex-linked recessive lethal (SLRL) assay. Following 72 h of feeding exposure, NG and NSG at concentrations of 4-8 micrograms ml-1 and 15-20

The metabolism of thiamethoxam [(EZ)-3-(2-chloro-1,3-thiazol-5-yl-methyl)-5-methyl-1,3,5-oxadiazinan-4-ylidene (nitro) amine] was investigated in whole plant, callus, and heterotrophic cell suspension culture of aseptically and field grown tomato (Lycopersicon esculentum Mill.) plants. The structure of the metabolites was elucidated by chromatographic (HPLC) and spectroscopic

A spectrometer based on acousto-optic tunable filters is developed for use in measuring Raman spectra as part of a detection system that is low-cost, reliable, and field-portable. The system is coupled with a fiber optic bundle to carry the excitation
Conidia of Trichoderma harzianum F-340, an active producer of fungal mutanase, were mutagenized with physical and chemical mutagens used separately or in combination. After mutagenesis, the drop in conidia viability ranged from 0.004% to 71%. Among the applied mutagens, nitrosoguanidine
