Residue field trials for application of Flint (active ingredient: trifloxystrobin) on curry leaf plots were conducted in the states of Selangor (Serdang) and Johor (Ayer Hitam and Bukit Lawiang). In total four residue field trials were conducted from the period of 2015 to 2016. In each residue trial four applications of Flint were made (two-week intervals between applications). The number of applications in each trial was set at four within one growing season of curry leaves development from shoot development to mature leaves. The experimental plots were treated with foliar spray at the rate of 125 g/ha trifloxystrobin. Curry leaves samples were collected at 0 1 3 7 14 21 and 28 Days After Last Application (DALA) of Flint. In all the four residue field trials trifloxystrobin and trifloxystrobin acids were detected in the range of 0.089 “ 21.182 mg/kg and 0.01 “ 0.363 mg/kg respectively. Based on the residue data and selected Pre-Harvest Interval (PHI) of 14 days for Flint use on curry leaf farms the Organization for Economic Co-operation and Development (OECD) MRL calculator proposed a Maximum Residue Limit (MRL) of trifloxystrobin at 3 mg/kg and in terms of dietary risk assessment no acute or chronic risk to the general population resulting from the proposed MRL.

Abstract

Residue field trials for application of Flint (active ingredient: trifloxystrobin) on curry leaf plots were conducted in the states of Selangor (Serdang) and Johor (Ayer Hitam and Bukit Lawiang). In total four residue field trials were conducted from the period of 2015 to 2016. In each residue trial four applications of Flint were made (two-week intervals between applications). The number of applications in each trial was set at four within one growing season of curry leaves development from shoot development to mature leaves. The experimental plots were treated with foliar spray at the rate of 125 g/ha trifloxystrobin. Curry leaves samples were collected at 0 1 3 7 14 21 and 28 Days After Last Application (DALA) of Flint. In all the four residue field trials trifloxystrobin and trifloxystrobin acids were detected in the range of 0.089 “ 21.182 mg/kg and 0.01 “ 0.363 mg/kg respectively. Based on the residue data and selected Pre-Harvest Interval (PHI) of 14 days for Flint use on curry leaf farms the Organization for Economic Co-operation and Development (OECD) MRL calculator proposed a Maximum Residue Limit (MRL) of trifloxystrobin at 3 mg/kg and in terms of dietary risk assessment no acute or chronic risk to the general population resulting from the proposed MRL.
