| Experiment Title | Dissipation behaviour and dietary risk assessment of combi-product Chlorantraniliprole and λ-cyhalothrin residues in/on Indian bean (Lablab purpureus L.) | ||
| Research Type | Departmental Research | ||
| Experiment Background | Indian beans (Lablab purpureus L.; Family Fabaceae) are popular vegetable in India is a poor man’s meat as it has many nutritional benefits and it is the best source of digestible vegetable protein (20-25%) required for human health.It is multipurpose crop use as vegetable, pulse and forage. A wide range of pesticides are used for the production of Indian beans. Nowadays, farmers across the globe preferred amalgam of pesticides over its single counterparts due to a broad spectrum of pest control with cost-effectiveness and resistance management in pests. The mixture of chlorantraniliprole 9.26 % and λ-cyhalothrin 4.63 % ZC has been registered in India to cater the protection from pod borer problem in pigeonpea (CIBRC, 2023).Insecticides viz., Flubendiamide, Indoxacarb, λ-cyhalothrin, and Chlorantraniliprole etc. are extensively used to control the pod borer infestation problem in Indian bean. These pesticides have potentially adverse effect on human health. Especially, South Gujarat is major producer of Indian bean. Therefore, it becomes essential to study the behaviour and dietary risk assessment of combi-product Chlorantraniliprole and λ-cyhalothrin residues in/on Indian bean. | ||

| Treatment |
1. Control – water spray 2. Recommended dose @ 30ga.i/ha 3. Intermediate Dose @ 37.5 g ai/ha 4. Double to recommended dose @ 60 ga.i/ ha Note : Any commercial formulation of chlorantraniliprole 9.26 % and λ-cyhalothrin 4.63 % ZC will be sprayed at twice; 1st at 50 % flowering stage and followed by second spray at 15 days interval Methodology : Any commercial formulation of chlorantraniliprole 9.26 % and λ-cyhalothrin 4.63 % ZC will be sprayed twice; 1st at 50 % flowering stage and followed by second spray at 15 days interval at three doses specified above. Dissipation and persistence Sampling : Indian bean : -0 day (2 hrs after last spray), 1, 3, 5, 7, 10, 20, 30 days Soil : 0 day and 30 DAA Sample collection : Indian bean pods: Approx. 500 g Indian bean pod samples will be collected from each treatment and will be subjected to residue analysis with QuEChERS approach and quantification. Soil : Approximately 1 kg soil samples will be collected from 5 sampling sites per treatment with standard sampling procedure and processed with QuECHERS approach. Dietary risk assessment The residues of chlorantraniliprole and λ-cyhalothrin in/on Indian bean obtained at 0 day were considered for dietary risk assessment calculations. The dietary exposure and risk assessment will be worked out by using estimated daily intake (EDI) and risk quotient (RQ). EDI = [Residue (mg/kg ) X Food consumption (kg/day )] / Body weight (kg) Body weight and food intake for various age groups of the Indian population will be taken into account when doing the calculations in accordance with the references of the National Institute of Nutrition, Hyderabad (ICMR, 2011). RQ = EDI / ADI Where RQ is the risk quotient, EDI is the estimated daily intake (mg/kg , bw) and ADI is the acceptable daily intake (mg/kg , bw). In terms of numbers, a chemical that has an RQ value greater than 1 is risky for consumers (Mariappan and Kaithamalai, 2020; Kansara et al., 2021; Singh et al., 2023). Observations:
