| Abstract: | Indoor toxicity and field efficacy were tested to determine theefficacies of 0. 5% spinosad emulsion in water in controlling the pest of Thrips palmi Karny. The results indicated that LC50 was 5.37 μg· mL-1 indoor toxicity and the corrected field efficacy for 7 d was 91.11%. It was stated that the validity period of field efficacy was better, and the recommend dose was 26.25 g/ha - 37.5 g/ha. |
