Micro-Injection of Systemic Insecticides into Trees
Systemic insecticides, used as foliar sprays, soil drenches and granular applications
to trees for control of a number of important pests, are not new.
Several companies have been developing various methods of injecting these same
systemic insecticides directly into the trunks of trees to allow the vascular transport
system to distribute the pesticide throughout the plant. Some of these injection systems
use 3/8-inch to 1/2-inch holes for injecting or implanting capsules. Recent evidence
indicates that these larger diameter holes may not heal rapidly on some species of trees.
Therefore, these techniques should probably be avoided.
Other injection systems use much smaller injection holes, "micro-injection," which
seem to heal more rapidly. The following two systems are nationally available:
Mauget System The J. J. Mauget Company, 5435 Peck Rd., Arcadia, CA 91006 provides a microinjection system which uses prepacked plastic containers which can be compressed to
provide internal pressure. An 11/64-inch drill bit is used to make holes in the tree trunk
and a microinjector tube is inserted. The compressed container is then attached and the
pesticide is injected into the tree vascular system. Mauget provides the following
products:
IMICIDE (imidacloprid), IMISOL (imidacloprid plus DEBC), ABACIDE (abamectin) and
ABASOL (abamectin plus DEBC) are labeled for use on ornamental trees and shrubs.
INJECT-A-CIDE B (dicrotophos) is for use on trees listed on the label. IMICIDE and
IMISOL have adelgids, aphids, beetles, borers, lace bugs, leafhoppers, mealybugs, pine
tip moth, scale, thrips and whiteflies listed on the label. ABACIDE and ABASOL have
bagworms, beetles, caterpillars, leafminers, mites and spittlebug listed on the label.
INJECT-A-CIDE B has aphids, beetles, borers, caterpillars, galls, lace bugs,
leafhoppers, leafminers, mites, pine beetles, pine tip moth, psyllids, scales and
spittlebugs listed on the label.
Tree Tech Microinjection Systems, Inc.
Tree Tech Microinjection Systems, Inc., 950 215th Ave., Morriston, Fl 32668 has
developed a micro-injection system which uses prepacked plastic containers which can
be compressed to provide internal pressure. A 11/64-inch drill bit is used to make holes
in the tree trunk and a tip with container is inserted. A tap with a mallet seats the tip and
compresses the container.
Vivid II (abamectin) is labeled for use on ornamental trees (including forest, noncropbearing as well as woody shrubs) for control of adelgids, aphids, browntail moth,
elm leaf beetle, lace bug, lygus bug, mites, oakworm, scale, white pine weevil, engraver
beetle, eucalyptus borer and flatheaded borer.
Dendrex (acephate) is labelled for use on flowering crabapple for control of aphids, tent
caterpillars and leafrollers. It is labeled for other trees and shrubs for control of aphids,
bagworms, birch leafminer, tent caterpillars, lace bugs, tussock moth larvae, Gypsy moth
larvae, scale crawlers, grasshoppers, cankerworms (spring and fall), Nantucket pine tip
10
moth, Zimmerman pine moths, root weevil adults, boxelder bugs, thrips, whiteflies,
bronze birch borer, Japanese beetles, elm leaf beetle (larvae), and other listed pests.
Harpoon (oxydemeton-methyl) is labeled for the following trees and pests: cedars (bark
beetle), cottonwoods (aphids), Douglas-fir (cone moths, engraver beetles), elms (elm
leaf beetles), junipers (bark beetles), pines [except pinyon] (6-spined engraver beetles,
flatheaded borer, black turpentine beetle, Nantucket pine tip moth, pine needle scale
and a few other listed pests), redwood (bark beetles, mites and needle scale), spruce
(adelgids) and walnuts and pecans [non-bearing] (aphids, mites).
Insect & Mite Control Recommendations for Trees & Shrubs
Use Pesticides Properly to Prevent Pollution
The proper use of pesticides will reduce the pollution of our environment to the
necessary minimum. Pesticides are carried into water on soil particles that erode. Take
measures necessary to prevent erosion. Do not pour excess spray mixtures or
pesticides into the sewage systems. Every little bit disposed of in this way adds to the
stream pollution problem. Wash the residues from your empty container and mix it into
your garden spray. Apply the last drop of the pesticide to your plants. Triple or pressure
rinse container, puncture or crush and put in a sanitary landfill. Observe wind conditions
and avoid spraying during periods of windy weather to prevent drifts.
Anticipate Pest Problems
Every ornamental plant is host to a variety of insect pests during the growing season.
Anticipate insect problems and inspect the leaves, stems, buds and flowers of
ornamentals regularly. Frequently, the problem can be identified by observing the injury
which results from the feeding activities of the insect. Damage from a heavy infestation
can be prevented by early detection and control.
Emergence of Insects
Insects will begin to feed and deposit eggs when the temperatures rise to 50 to 65 F or
above and remain in this range for one to two weeks. In some years, pests may appear
one to two weeks earlier or later than in other years because of an early or late spring.
Effective Spraying
Insecticides are most effective when they are applied to the parts of the plant on which
the young larvae or nymphs are feeding. A fine-mist spray will thoroughly wet the plant
surfaces. Stop spraying when the plant surfaces are wet to the point of run-off or
dripping. Repeat the spray applications at regular intervals to control the late-hatching,
emerging or migrating insects.
Apply an insecticide when weather conditions are favorable. The temperatures should
be in the 60 to 80 F range with a wind velocity of less than five miles per hour, with no
rain forecast for 24 hours. If one-half inch or more of rainfall occurs within 12 hours after
spraying, repeat the application.

Preparing A Spray
Rev. 2/11
Pesticides are formulated as emulsifiable concentrates or wettable powders for dilution in water or as granules to be
applied on or in the soil. Accurately measure the amount recommended for the volume of dilute spray you need. The concentrates
may contain either one, two, three, four or seven pounds per gallon of the active insecticidal ingredient. The safety margin is reduced
considerably when too much insecticide is added to the dilute spray. Injury to plants and overexposure to the home gardener
frequently results from using too much insecticide.
Read the label thoroughly before you mix a spray. The four most important minutes in any pest control project are the time
required to read and understand the label.
Overexposure to insecticides can result from oral ingestion, inhalation or absorption through the skin. The amount any one
individual can tolerate without becoming ill may vary according to age, weight, sex and health. The potential toxicity is based on test
results with experimental animals. The insecticides Di-Syston, Metasystox-R2 and Diazinon have a high dermal absorption potential.
The oral poisoning potential for these insecticides is extremely high. Observe the caution and warning statements on all insecticide
labels. Wear the prescribed protective equipment and apply the insecticides in recommended situations according to label directions.
The potential toxicity is increased many times when the amount recommended for a spray application is doubled. Mixing
two or more insecticides together can also greatly increase the potential toxicity of a spray.
Table 3. Spray Estimate Chart
Estimate the amount of dilute spray material required to thoroughly cover your infested plants to the point of run-off. When the spray
begins to drip off, you have applied a sufficient amount. A fine-mist spray will give a better, more uniform coverage to the plant.
