abstract
The study was carried out to assess the efficacy of Oberon 22.9% (spiromesifen) SC against okra red spider mite at surrounding area of PAU Regional Research Station Gurdaspur. The efficacy of Oberon 22.9% @ 250, 375 & 500 ml was compared along with earlier recommended insecticide Rogor 30 EC @ 675 ml per hectare. The results revealed that all the insecticidal treatment significantly decreased the mite population (1.41 to 2.04 mites/2 cm² leaf area) as compared to control (21.01mites/2 cm² leaf area) fourteen days after spray. But Oberon 22.9% @ 500 ml/ha showed high performance with least mite population (1.41) and it was par with its median and lowest doses with mite population (1.71 & 1.93) and Rogor 30 EC (2.04). The maximum fruit yield (100.42 q/ha) was recorded with highest dose of Oberon. All the acaricidal treatments under present study had no any significant impact on population of natural enemies of red spider mite.
