Persistence of chlorantraniliprole in coastal alluvium soils of Kerala under different moisture regimes

Greeshma Suresh and Thomas George
Chlorantraniliprole, an anthranilic diamide insecticide effective against several lepidopteran as well as coleopteran, dipteran, and hemipteran pests belongs to carboxamide group. This compound is reported to have very high efficacy as an insecticide and in general possess low mammalian toxicity. These basic properties along with a broad -spectrum insecticidal action renders it to be the one of the most frequently used new generation insecticide against lepidopteran pests. Though Chlorantraniliprole, with a medium toxicity profile has proven efficacy in the field, the environmental impact of the insecticide needs to be studied in detail. The study focused on persistence of chlorantraniliprole in coastal alluvium soil of Kerala under two different moisture conditions viz. field capacity (M1) and flooded (M2) conditions in the laboratory at three different concentration levels, viz. C1(1 mg kg-1), C2(2 mg kg-1), C3 (4 mg kg-1). The calculated half-life for coastal alluvium soil were 13.84 days (T1), 17.10 days (T2), 23.88 days (T3) under field capacity and 9.18 days (T4), 10.72 days (T5) and 13.35 days (T6) under flooded condition respectively. Data revealed that, half-life was lower under flooded condition than field capacity condition. The increased level of application had prominent effect on half-life and increased correspondingly. The data revealed that the mean residue content of chlorantraniliprole in soil considerably decreased with time and reached BQL within 75th day after the application for both the soil conditions.
