Indiscriminate use of insecticides to combat the insect pests has led to accumulation of residues in okra which are harmful to consumers. In the present study, an attempt has been made to study the dissipation of chlorpyriphos on Okra fruits under agro-climatic conditions of Jammu where no study has been carried out earlier. Field experiments have been conducted for two consecutive years 2004 and 2005 to work out the safe preharvest interval. The average initial deposits of 0.91 mg kg-1 and 1.46 mg kg-1 have been recorded on okra fruits treated with the recommended (500g a.i. ha-1) and double the recommended dose of chlorpyriphos (1000g a.i. ha-1) respectively, showing percentage dissipation of 97.80 and 98.63% correspondingly. On the basis of dissipation and prescribed MRL of 0.20 mg kg-1 of chlorpyriphos for okra, the half-life for the recommended and double the recommended dose has been worked out to be 1.33 and 1.41 days, respectively. The safe waiting period of 2.92 and 4.06 days have been suggested for the recommended and double the recommended dose of chlorpyriphos, respectively.
