Buying Guide: Key Purchase Considerations

What should you evaluate before buying? First, identify the primary pests and diseases in your fruit trees. Consider whether you need a single product for both insects and fungal issues (dual-action) or a targeted insect killer with separate disease controls. For edible landscapes, prioritize products labeled for fruit trees and safety for harvest-time use.

How important is crop compatibility? Look for labels listing your fruit types (apples, citrus, stone fruit, nuts) and check any restrictions on use with edible plants. This reduces the risk of phytotoxicity and ensures compliance with local regulations.

What about application method and frequency? Ready-to-spray formulations save time but may require more frequent applications. Concentrates can be cost-effective but demand proper dilution and attachment to spray equipment. Consider your routine, weather windows, and ability to apply to the canopy and undersides of leaves.

Systemic vs. contact control: Systemic products move within the plant, protecting new growth; contact products act on pests on contact. In mixed orchards, using a blend of both approaches can provide layered protection, but always follow label directions to avoid overuse or conflicting applications.

Safety and harvest timing: For edible crops, verify days-to-harvest restrictions and ensure that products permit application up to the day of harvest when appropriate. Keep children and pets away during and after application as directed by the label.
