Superior Disease Control for Unrivaled Plant Health

Untreated Almond

Untreated
Preventive applications are the best way to protect your orchards from disease. Once disease is visible in your orchard, it is often too late to prevent excessive damage.

Treated Almond

Healthy Nuts From the Inside Out
Proactive planning and early-season fungicide applications are essential to minimize disease impact and protect yield potential.

Insect Threats

Leaffooted Plant Bug

Leaffooted Plant Bug (March-May)
Common late-season insects, like plant bugs, reproduce rapidly during hot summers. Learn how to protect nut quality by controlling these insects.

Don’t Just Control NOW

California tree nuts face differing pest pressures each year, and the ones taking the biggest bite from your yield must take priority. A planned approach is essential to control pests and combat resistance.

  • Status-quo management programs that control a singular pest, like navel orangeworm (NOW), won’t deliver your highest marketable yield potential if your field faces insect pressures on all fronts.
  • Pests like spider mites, peach twig borer, leaffooted plant bug and codling moth can cause significant economic injury to tree nut crops, especially alongside NOW. Using multiple modes of action can decrease insecticide resistance pressure.
  • For higher nut yield potential with better quality, create a plan to manage a broad-spectrum of insect threats.

Broad-Spectrum Insect Control, All Season

A customized program approach to season-long insect control ensures high-quality nuts with greater yield potential. You are the expert in your orchard – you know what optimal timing and ideal formulation looks like for the pests in your crop.

  • Insecticide applications perform at their highest efficacy, with the most efficiency, when timed to control the multiple pests your orchard faces.
  • A single pest shouldn’t dictate a pest control program when overlapping pest populations threaten to diminish your harvest.
  • A management plan with flexibility allows you to target insects before they cause costly damage.
  • Deliver more efficiency for fewer rejected nuts and a higher profit potential at harvest with proven insecticides that allow customizable control of pests in almonds, walnuts and pistachios.
