  • Arbotect 20-S

Dutch elm disease:

  • Protects healthy elms from beetle transmission of Dutch elm disease for three growing seasons.
  • Annual treatments are not required. Provides "gap-free" protection.
  • Arbotect moves into the new growth in the spring and protects this tissue when the beetles are highly active.
  • Track record of performance is over 25 years with success rates over 99 percent.

Sycamore anthracnose:

  • Improves the appearance of infected sycamores over multiple years.
  • Application by macro-infusion is a closed system - no drift, and minimal applicator exposure.

Rainbow Recommends

Arbotect became the industry standard with Dutch elm disease for a simple reason: it works better than any other option. Elm trees are susceptible to infection early in the growing season but treatments cannot be performed until the tree is fully leafed out for the year. This means there is a several-week gap early in the year where other treatments leave the tree exposed to a possible infection. Arbotect not only lasts 3 seasons in the tree, but the product moves into the new growth. This allows a tree to be fully protected early in the season, which is a common time for elm trees to become infected.
