Several common insect and disease problems can be managed through use of systemic products injected into the soil at the base of plants, or directly into plant tissue. A single soil or trunk injection will provide effective results from one to three growing seasons, depending on the insect or disease we are treating.

Some insect and disease problems are best treated with foliar applications. At John B. Ward and Co., we use only the most effective, environmentally safe products on the market. We treat only when necessary and our technicians are licensed and extensively trained to professionally apply sprays.

All too often in a suburban landscape we encounter a tree growing in poor, compacted soil. Years ago, the only recommendation was to install a mulch or wood chip circle to the drip line, water properly and maintain fertility. Within the past decade, we have been using a tool called the Air Spade to safely aerate the compacted soil and incorporate high quality compost directly into the root system. This procedure dramatically improves the growing conditions right away and the results have been very good.

At the cutting edge of tree care are the newest methods of direct trunk injection. We use both large volume (macroinjection) and small volume (microinjection) methods to manage various insect and disease threats without the risk of unintended exposure due to drift or runoff. Direct injection methods often have multiple year effectiveness and can compete economically with foliar or soil treatments. Dutch Elm Disease, for example, can only be effectively managed with a macroinjection of a systemic fungicide.
