Build me a full organic IPM calendar for pest control in a season

Think of organic pest control as a season long plan in stages, not a single spray. Before sowing, choose a resistant or tolerant variety, do deep summer ploughing to expose grubs and pupae, plan crop rotation away from last year host, and prepare Trichoderma and Pseudomonas enriched FYM for the soil. At sowing or planting, do seed treatment with Trichoderma or Pseudomonas, apply neem cake to the soil, sow on the recommended early date to escape peak pest flights, and set up trap crops like marigold or castor and border rows. Early crop stage, put up yellow and blue sticky traps and pheromone and fruit fly traps as monitoring, fix bird perches, and start preventive neem sprays. Through the season, scout the crop twice a week, read your traps, and conserve natural enemies by not spraying broad chemicals. When a pest crosses its action threshold, escalate to the right biopesticide, Bt or NPV for caterpillars, Beauveria for sucking pests, and release Trichogramma for borers timed to egg laying. Keep up field hygiene, remove infested plants and fallen fruit. Only if a pest goes past safe limits despite all this do you consider a recommended last resort measure. The whole secret is prevention plus early monitoring plus combining methods, no single tool carries the season. Tune the exact timings and thresholds for your crop and area with your local KVK.
