Buying Guide
Key purchase considerations help match a product to your trees and landscape. Consider the target insects, duration of protection, and whether you prefer a liquid drench, granules, or ready-to-use concentrate. For larger properties, selecting a product with a long protection window minimizes maintenance. If you want added nutrition, choose products that combine feeding with pest control. Always follow label instructions for application timing and safety around non-target plants, pets, and waterways.
What should I use for aphids on young trees?
Systems that move through the root zone to foliage are effective for young trees. Look for products labeled for trees and shrubs with aphids and a long protection period, such as 12 months.
Should I choose a liquid drench or granules?
Drenches provide rapid systemic movement and are convenient for established trees. Granules can be broadcast in larger landscapes and often include nutrition benefits, but may require dilution and watering for root uptake.
Is a 12-month protection claim reliable?
Protection duration reflects label claims under typical conditions. It reduces reapplication frequency but always monitor trees for signs of new infestations and re-treat as directed if aphids reappear.
Can these products affect beneficial insects?
Systemic insecticides can affect non-target insects if misapplied. Always apply precisely as directed, avoid flowering periods when pollinators are active, and consider selective products when beneficials are present in your landscape.
What about combining pest control with fertilization?
Some products combine feeding with pest control. If your trees show nutrient deficiencies, a combined option may provide both protection and growth support, but ensure you do not exceed recommended application rates.
How to apply safely and effectively?
Read and follow all label directions. Use protective gear as required, water in after application if instructed, and avoid applying during extreme heat or drought conditions. Dispose of residuals per local guidelines to protect the environment.
FAQ
- What is the best product for aphids on established trees?
Consider long-duration systemic products labeled for trees and shrubs, such as BioAdvanced or Fertilome drenches or granules, which provide up to 12 months of protection in many cases.
- Do systemic granules work as well as drenches?
Granules move systemically through roots, but may require watering and longer setup time. Drenches can deliver faster uptake in some trees.
- Can I use these products on fruit trees?
Yes, many products are labeled for use on specified fruit trees; always check the label to confirm which species are covered.
- Will these products kill beneficial insects?
Improper use can affect non-target insects. Apply only as directed and avoid flowering periods when pollinators are active.
- Is one treatment enough for the season?
Most products offer up to 12 months of protection, but aphid pressure varies. Monitor trees and re-treat as directed if needed.
