Use of aqueous plant extracts to reduce profenofos residues in the leaf of mustard (Brassica juncea L.) and suppression of the grasshopper population

Profenofos is an active ingredient from the organophosphate group which residue often found in various fresh and processed vegetable products. This study aimed to assess use of aqueous plant extracts Sapindus rarak seeds, Luffa acutangula peel Centella asiatica leaves reduce profenofos residues leaf mustard evaluate their performance suppressing grasshopper populations. S. L. peels C. were dried filtered using a 100 mesh sieve. A total 30 gm samples each mixed with 1000 ml water blended at 800 rpm, then sieve before use. The field experiment was performed by spraying pesticide concentration 3 l-1 dose per plant. Two days after application, plants sprayed extracts. Twenty-four hrs detected UPLC-MS/MS machine. phytotoxicity test results showed that did not cause any phytotoxic symptoms. Furthermore, experiment, control residual value 2407.62 ng g-1. Results PL treatment (aqueous extract seeds) 1502.05 g-1, recorded PP leaves) 1316.27 g-1 PG peels) 660.71 In treated plants, decreased 37.48% 72.55%. number grasshoppers significantly different control. provides new information can suppress population leaf.
