Persistence of chlorantraniliprole granule formulation in sugarcane field soil

Abstract

Chlorantraniliprole, an anthranilic diamide insecticide with novel mode of action, is found effective against several lepidopteran as well as coleopteran, dipteran, and hemipteran pests. The present studies were carried out to study the persistence pattern of chlorantraniliprole on sugarcane field soil following application of granule formulation. The residues of chlorantraniliprole were estimated using high performance liquid chromatograph (HPLC) and confirmed by liquid chromatograph-mass spectrometry (LC-MS/MS). Following application of chlorantraniliprole (Ferterra 0.4G) at 100 and 200 g a.i. ha(-1), the average initial deposits of chlorantraniliprole were observed to be 0.88 and 1.59 mg kg(-1), respectively. These residues dissipated below the limit of quantification (LOQ) of 0.01 mg kg(-1) after 56 days of the application of insecticides at both the dosages. The half-life values (t 1/2) of chlorantraniliprole were worked out to be 8.36 and 8.25 days, at recommended and double the recommended dosages, respectively.

Effect of Different Soil Treatments on Dissipation of Chlorantraniliprole and Dehydrogenase Activity Using Experimental Modeling Design

“…Zhang and others studied the recovery of CAP in rice field ecosystem and they reported that the recovery was ranged from 76.90 to 103.10% at 0.0001 to 0.1 mg/kg (Zhang et al 2012). Sharma and co-authors studied the recovery of CAP in sugarcane field soil and they found that the recovery was ranged from 87.29 to 95.80% at 0.01 to 1.00 mg/kg (Sharma et al 2014b). Wang and Zhang studied determination of the dissipation dynamics and residue behaviors of CAP in soil by LC-MS/MS they found that the recovery was ranged from 81.90 to 97.7% at 0.010 to 4.00 mg/kg (Wang and Zhang 2017).…”

“…Zhang and other calculated the half-life of CAP in soil of rice field ecosystem to be 16.0 days (Zhang et al 2012). Malhat et al studied the results showed half-life value of 3.30 and 3.66 days for CAP in tomato fruit and soil ) and the dissipated in tomato fruit and soil followed the first order kinetics Sharma et al 2014b). Vijayasree et al and Ramasubramanian et al reported that CAP dissipated rapidly in cowpea fruits, with a half-life of 1.31 day and persisted in soils of sugarcane with longer half-life of 6.5-6.8 days (Ramasubramanian et al 2012;Vijayasree et al 2013).…”

Sharma et al studied the persistence of CAP granule formulation in sugarcane field soil and they reported that the half-life of CAP changed from 8.36 to 8.25 days (Sharma et al 2014b). Malhat found that CAP dissipation in grape was 38.95, 61.29, 82.70, 93.67 and 98.09%, at 1, 3, 7, 10 and 15 days respectively (Malhat 2012).…”

Comparative ecotoxicity of chlorantraniliprole to non-target soil invertebrates

“…However, no ecotoxicity data are available for other soil invertebrate species, while CAP residues are expected to accumulate in soil due to its persistence in soil (half-life up to 1130 days in dissipation studies on bare ground, USEPA, 2008). Sharma et al (2014) reported an average initial CAP concentration in a sugarcane field soil of 0.88 mg/kg dw after the application of CAP at the recommended dose of 100 g a.i./ha. This indicates that exposure of soil invertebrates is likely to occur.…”

“…With the application of chlorantraniliprole at 100 and 200 g a.i. ha − 1 , the half-life values were calculated as 8.36 and 8.25 days, respectively (Sharma et al 2014).…”
