Bihar Plant Protection Supervisor and Inspector Syllabus Preparation Strategy 2026

With the release of the Bihar Plant Protection Supervisor and Inspector Syllabus, candidates should begin structured preparation before the official notification and applications start. The syllabus is technical and subject-heavy, so a focused approach is necessary.

A balanced preparation plan covering both Paper-1 and Paper-2 simultaneously will give better results than preparing them separately.

Key Preparation Approach

• Prioritize Entomology, Plant Pathology, and Nematology as they are core plant protection subjects.
• Strengthen concepts of IPM, IDM, insecticide classification, toxicity (LD₅₀, MRL), and major crop diseases.
• Revise Agronomy and Soil Science fundamentals, especially cropping systems, irrigation, soil fertility, and nutrient management.
• Prepare short notes for Acts and provisions like the Insecticides Act and plant quarantine measures.
• Practice agriculture-based MCQs regularly and revise subject-wise every 10–15 days.
• Early preparation with consistent revision and concept clarity will significantly improve performance once the exam dates are announced.
