Horizon Forestry™ maintains a large fleet of Colorado's most advanced and powerful tree spraying and pesticide application equipment including High Volume High Pressure (HVHP) and FMC Rotomist® sprayers capable of effectively treating even the tallest Pines and Spruces.

A successful bark beetle pesticide application program has four objectives;

• Diagnosis of the problem.
• The right chemical and rate.
• Proper timing.
• Thorough coverage.

When considering a pesticide applicator, consider the following;

1. The effectiveness of control and treatment of the spread of Mountain, Pine, Ips, Spruce and other bark beetles varies dramatically by the technology used in the application of the pesticide as well as the pesticide used itself.
2. A programmed approach to pesticide application has the highest success rate including spring, mid-summer and fall applications. This approach will provide the best results in protecting high-value, specimen or older growth trees.
3. Large and older growth trees, as well as trees stressed by drought, over-crowding or other environmental factors have proven to be the most susceptible to beetle attack.
4. High Volume High Pressure (HVHP) pesticide application technology has proven itself as the most effective means in combating invading beetles, with other technologies providing varying degrees of success.

Important Note:
Recent studies conducted by the US Forest Service have shown the use of Micro-injection as a means of pesticide application as being an ineffective control in stopping the spread and infestation of Mountain, Pine, Ips, Spruce and other bark beetles.

Horizon Forestry™ supports multiple pesticide application technologies and capabilities including:

• Advanced High Volume High Pressure (HVHP) sprayers capable of reaching heights in excess of 100' @ 800 PSI and 65 GPM.
• FMC Rotomist® sprayers that deliver pesticides in a focused stream of air to the highest heights and can treat large forested areas economically and in a short amount of time.
• Conventional Low Volume Low Pressure (LVLP) sprayers for use on smaller trees 30' or less in lawns, residential and light commercial environments.
• Portable Backpack Mist Blower sprayers for use on steep, rugged or difficult terrain.

Horizon Forestry™ is Colorado's only commercial applicator to utilize the rugged all-terrain capabilities of the Mercedes Unimog. With it's unique capabilities we can move our equipment through areas previously unreachable by conventional 4x4 trucks and pickups.

Our offices stock a complete line of pesticides for the control of bark beetles including Permethrin E-Pro, Carbaryl 4L®, Astro®, Dragnet®.and Onyx®
