Overview

Growing pecans in a home orchard setting comes with unique challenges but also unique opportunities. Unlike commercial growers, homeowners can prioritize tree health, aesthetics and long-term sustainability over maximum yield. Integrated pest management (IPM) is a practical, flexible approach that helps you meet those goals by combining prevention, observation and selective intervention.

IPM isn’t about spraying more or less. It’s about making informed decisions. It starts with choosing the right cultivars and planting sites, continues with regular monitoring for pests and diseases, and ends with targeted action only when needed. By using cultural, biological and chemical tools together, IPM helps you protect your trees, reduce unnecessary inputs and support beneficial organisms in your landscape.

This publication will walk you through the core principles of IPM, show you how to scout effectively, and help you build a seasonal plan that fits your orchard’s size, age and goals.

This publication will cover:

1. Core Principles of IPM for Pecans: IPM relies on prevention, careful monitoring, and a mix of control strategies. Cultivar selection, orchard layout and airflow reduce disease risk. Decisions are guided by thresholds, and tools include cultural, mechanical, biological and chemical options. Resistance management ensures long-term effectiveness.
2. Planning for Success: IPM Starts Before You Plant: Success begins with scab-resistant cultivars, wide spacing for airflow and avoiding pest-prone sites like patios or wooded edges. Consider equipment limitations early to avoid future challenges.
3. Monitoring and Decision-Making in Home Orchards: Visual scouting helps identify pests and diseases. Understanding seasonal cycles and phenology (e.g., budbreak, nut fill) informs when to act and when to tolerate minor issues. Traps and thresholds support informed decisions.
4. Cultural and Mechanical Controls: Sanitation (removing fallen debris), pruning for light and airflow, and managing groundcover to reduce pest habitat. Physical barriers like trunk bands help control specific pests such as weevils.
5. Supporting Natural Enemies: Encourage beneficial insects by avoiding broad-spectrum insecticides and planting diverse groundcovers like clover and wildflowers. These allies help maintain natural pest control.
6. Chemical Controls in an IPM Context: Use chemicals only when justified. Choose homeowner-accessible products, rotate modes of action (FRAC/IRAC) and consider limitations like sprayer reach and tree height. Soil-applied options may be useful when foliar coverage is difficult.
7. IPM Tools by Tree Age: Young trees benefit from trunk sprays, soil drenches and early scouting. Mature trees rely more on prevention and cultural practices. For large trees, professional applicators may be needed.
8. Building a Year-Round IPM Calendar: Create a seasonal checklist of pests, diseases and actions. Align IPM tasks with pruning, fertilization and other orchard maintenance to streamline care.
9. Troubleshooting and Adjusting Your IPM Plan: Persistent problems may require reassessing cultivar choice, airflow or nutrient stress. Be ready to revise your strategy based on changing conditions or new observations.
