Kienholz et al have shown that excess amounts of ascorbic acid equivalent to four grams per day for humans, administered to chicks during the first month after birth resulted in a high rate of mortality. Similar effects on the toxicity of excess ascorbic acid in guniea pigs, fed on unfortified wheat diet, has been reported.

A field experiment was conducted to study the rate of dissipation of thiamethoxam 25% WG in vegetable cowpea. Thiamethoxam 25%WG @ 0.24 ml l-1 was sprayed at pod formation stage, and samples of pods were harvested at 0 (2 hr after spray), 1, 3, 5, 7, 10, 15 days after spray. Residues were estimated using liquid chromatography tandem mass spectrometer (LC-MS/ MS) at the All-India Network Project on Pesticides Residues, College of Agriculture, Vellayani, Kerala. The mean initial residue was found to be 0.53 μg g-1, and residues were observed persisting up to three days and reached below quantification level on fifth day.Keywords
