Abstract
The green leafy vegetables such as cabbage, kale, amaranth, spinach, fenugreek, coriander etc. are most common vegetables cultivated throughout the country. Pesticides like Profenophos, Chlorpyriphos, Triazophos and Quinalphos have been found effective for the management of these vegetable crops. These pesticides are from Organophosphate group and used on wide variety of vegetable crop to control many pest. Farmers are using large amount of pesticides during the entire period of cultivation for better production. Most of the farmers don’t follow the guideline for recommended doses and waiting period between the last spray and harvest. Due to this vegetable contains pesticide residues and it will adversely affect the human health. Therefore, the present study was undertaken entitled as “Study of gamma irradiation treatment for degradation of pesticide residues in selected leafy vegetables” with the aim of degradation of pesticides. In order to generate field level spiking of the insecticides under study on leafy vegetable, control plots of these vegetables were sprayed with the mixture of the pesticides at double the recommended dose at Main Vegetable Research Station, Anand Agricultural University, Anand. The vegetables were harvested after 24 hrs of application of pesticides. The vegetables were immediately subjected to residues analysis to know the initial levels and also were subjected to gamma irradiation and also for the microbial and physical analysis. Optimization of dose of gamma irradiation were accomplished on the basis of maximum degradation of pesticide residues and microbial decontamination of green leafy vegetables.
