title: Risk assessment of β-cyfluthrin and imidacloprid in chickpea pods and leaves.
abstract: Dissipation of β-cyfluthrin and imidacloprid in chickpea pods and leaves was measured following three applications of Solomon 300 OD (β-cyfluthrin 9 percent +imidacloprid 21 percent) at 200 and 400mLha(-1). Residues of β-cyfluthrin on chickpea pods and leaves were found to be below its limit of quantification (LOQ) of 0.01mgkg(-1) after 7 days at both the dosages. Similarly, imidacloprid residues were found to be below its LOQ of 0.01mgkg(-1) at 10 days. Half-life periods on chickpea pods and leaves for β-cyfluthrin were found to be 1.06 and 0.58 days, whereas for imidacloprid these values were observed to be 2.07 and 1.75 days at recommended dose. As the theoretical maximum residue contributions on chickpea pods and leaves are found to be less than the maximum permissible intake values even on 0 day, therefore consumer health risks are minimal at both the dosages on chickpea.
