dc.description.abstractABSTRACT The present investigations titled “Residue dynamics and dietary risk assessment of some insecticide on cabbage” were conducted in Department of Entomology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2021-22. Studies were carried out to evaluate the persistence of novaluron, flubendiamide and lambda-cyhalothrin on cabbage heads and soil; their risk assessment and effect of decontamination processes on the residues status of mentioned insecticides. In persistence study on cabbage heads, initial deposits at X dose of novaluron (@ 75 g a.i. ha-1), flubendiamide (@ 18.24 g a.i. ha-1) and lambda-cyhalothrin (@ 15 g a.i. ha-1) were found to be 1.143, 0.198 and 0.433 mg kg-1, respectively. At 1.25 X dose of novaluron (@ 93.75 g a.i. ha-1), flubendiamide (@ 22.8 g a.i. ha-1) and lambdacyhalothrin (@ 18.75 g a.i. ha-1), initial deposits were found to be 1.431, 0.238 and 0.541 mg kg-1, respectively. Residues of novaluron, flubendiamide and lambda-cyhalothrin reduced to half in 1.99, 3.63 and 1.46 days at X dose and 2.82, 4.64 and 1.89 days at 1.25 X dose, respectively. The residues of novaluron, flubendiamide and lambda-cyhalothrin were below limit of quantification on 15th, 10th and 7th day at X dose and 20th, 15th and 10th day at 1.25 X dose, respectively. The residues of tested insecticides were below limit of quantification in cabbage cropped soil at the time of harvest for both the doses. Dietary risk assessment studies of novaluron, flubendiamide and lambda-cyhalothrin on cabbage revealed that theoretical maximum daily intake (TMDI) was less than maximum permissible intake (MPI) and hazard quotient (HQ) was found to be less than 1 for different age categories in rural and urban areas, thus indicating all the tested insecticides to be safe for human consumption, provided proper waiting period was followed. Among various decontamination treatments, removal of outer leaves was found to be most effective (removal upto 52.74 per cent) followed by dipping in 5% NaHCO3 solution (upto 46.49 per cent) which was statistically similar to washing with lukewarm water + dipping in 1% NaCl solution (upto 42.29 per cent) followed by washing with lukewarm water + dipping in 2 % acetic acid solution (upto 35.05 per cent) followed by dipping in veggie clean solution (upto 27.2 per cent ) which was statistically similar to dipping in nimwash solution (upto 27.2 per cent) followed by lukewarm water washing (removal upto 21.28 per cent). However, washing with running tap water provide least relief of 14.93en_US
