Buying Guide
Key factors to consider when selecting a systemic aphid control for trees:
- Target scope: Choose products labeled for aphids on trees and shrubs, and consider whether you need systemic granules, liquids, or soil drenches based on your tree size and soil conditions.
- Delivery method: Systemic products rely on root uptake. Liquid concentrates and drenches are often best for established trees, while granules may suit larger landscapes or harder-to-reach root zones.
- Persistence and reapplication: Review how long protection lasts (weeks to months) and whether rainfall or irrigation affects performance. Plan reapplication timing accordingly.
- Coverage: Ensure the product covers the types of trees you have (fruit, nut, ornamental, or shrubs) and check for compatibility with edible crops if applicable.
- Environmental impact: Consider products with lower olfactory impact and assess any potential effects on beneficial insects. Follow label directions to minimize non-target effects.
- Safety and usage: Verify whether applications are suitable for indoor or outdoor use, and observe required intervals between application and harvest if you grow edible crops.
- Resistance management: For ongoing aphid pressure, rotate among products with different active ingredients to reduce resistance risk.
