The present investigation was carried out during 2024 at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, with an objective to assess the spray interval for management of major sucking pest of rose viz., aphid (Macrosiphum rosaeformis Hood), thrips (Rhipiphorothrips cruentatus), leafhopper (Edwardsiana rosae), mite (Tetranychus cinnabarinus). From the present investigation, it is concluded that the minimum pest population of the above-mentioned pests were recorded in the treatment T₁ (Abamectin 01.90 EC at five-day interval). This is followed by treatment T₂ (Abamectin 01.90 EC at six-day interval), treatment T₃ (Abamectin 01.90 EC at seven-day interval), treatment T₄ (Abamectin 01.90 EC at eight-day interval) and treatment T₅ (Abamectin 01.90 EC at nine-day interval). Since, up to the treatment T₆ (at ten-days) any sucking pests couldn’t crosses the Economic Threshold Level ETL, and ten-day spraying interval is found suitable for effective management of major sucking pest of rose. However, in the case of mite infestation it does not crosses the Economic Threshold Level (ETL) at any stage of crop.
