Abstract  Background:  Plant-derived compounds are alternatives of synthetic insecticides in sustainable agriculture.  Objective:  This study investigated the phytotoxic effect of higher concentrations (2, 4, 8 and 16%) of four plants extracts (Azadirachta indica, Mentha arvensis, D. stramonium and Citrus limonium) on cotton plants.  Methods:  Each concentration was replicated four times to check the phytotoxic effect (CO2-in, CO2-out, H2O-in, H2O-out and photosynthesis absorption rate (PAR) in randomized complete block design. Data was recorded after 12, 24, 48 and 72 hours of spray with the help of Photosynthetic CL 340 meter.  Results:  The results showed that CO2-in was more affected by the D. stramonium (131.65±0.38) at 8% concentration. The overall...
