We perform timely treatments using the least toxic or invasive method to maintain pests and diseases at a level that does not cause a problem to plant health. These treatments consist of foliar sprays, soil applications and trunk injections. The frequency and products used varies depending on the insect or disease, type of plant, its location, environment and the weather. By reducing injury to plants, we help them to better produce, utilize and store their own sugars which improves overall plant health.
Infestation by certain insects can cause the death of the host plant, a result that can often be prevented. Emerald Ash Borer is one of those insects. We offer trunk injected treatments to protect Ash trees from this pest. Trees that are already infested may not respond to treatment.
It should be noted that many insects are beneficial and not all diseases have a chemical control. Often insects and diseases are a secondary problem and the primary cause may go unnoticed. Focus should be on complete plant health care which may include; pruning, fertilization, aeration/vertical mulch/mcycorrhizae inoculation, watering, choice of plant and location, soil conditions, anti-desiccant applications and skoot rodent repellent.
