Buying Guide: Key Purchase Considerations

  • Scope of control: Choose a product that targets both insect pests and fungal diseases when possible for efficient tree protection.
  • Tree type compatibility: Confirm the product is approved for the specific fruits, nuts, or citrus you’re growing, as well as for ornamental trees.
  • Application method: Ready-to-use versus concentrate affects how often you mix and spray. Consider the size of your trees and your sprayer capacity.
  • Organic and pollinator considerations: If you prioritize organic gardening or pollinator safety, select OMRI-listed or botanically derived options and follow label timing around bloom.
  • Persistence and re-entry: Check how long the spray remains effective and any re-entry timing after application to protect children and pets.
  • Resistance management: Rotate products with different active ingredients to reduce pest resistance and prolong effectiveness.
  • Safety and PPE: Read label warnings and wear recommended protective gear during mixing and spraying.
