General Instructions:
No dilution is required; this product is intended to be applied undiluted directly into the trunk or branches of trees in order to provide systemic control of insect pests.
SilvaShield Injectable Tree Insecticide can be used as directed on ornamental trees in residential areas, business and office complexes, shopping complexes, multi-family residential complexes, golf courses, airports, cemeteries, parks, playgrounds, and athletic fields. SilvaShield also can be used in commercial forestry production, nurseries, greenhouses, and in state, federal, county and local recreational forests.
The active ingredient in SilvaShield Injectable Tree Insecticide has sufficient residual activity so that applications can be made preceding the attack of the trees by target pests. SilvaShield Injectable also controls existing infestations of most labelled pests. If the level of infestation is severe, the high label rate for the targeted pest is recommended.
Systemic activity occurs only after the active ingredient is translocated upwards in the tree. In some cases, translocation can take 10 days or longer, depending on the transpiration rate of the treated plant. The need for an application can be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods. For best results (i.e., to ensure uptake), application should be made when the tree is actively transpiring. Less than satisfactory results, including slow or reduced impact on beetles and larvae, may occur if trees are suffering from lack of moisture, thereby reducing translocation of the active ingredient.
For best results, dedicated injection equipment is recommended.
Application Equipment
SilvaShield Injectable Tree Insecticide can be applied with a variety of trunk injection devices. To minimise the possibility of corrosion of equipment, use chemically-resistant components or ensure thorough cleaning after use. For all injector systems, read carefully and follow all manufacturers’ directions for use.
Drilling the hole
With most injector systems, it is necessary to pre-drill holes prior to insertion of the applicator device.
Holes should be drilled deep enough to permit transport of SilvaShield upwards in the vascular tissue.
Take note of drill hole spacing in the critical comments of the directions for use.
To determine the number of injection holes needed, measure the tree circumference at 1.3m above the ground. Divide the circumference (as measured in centimetres) by the recommended hole spacing to determine the number of holes needed. Initial injector sites should be in the active sapwood. If a single hole cannot accept its full dose, the dose may be divided among the other initial injection holes. Spacing of injection holes should be vertically and horizontally staggered so that they are not aligned with other holes.
No information is available that indicates physical compatibility with other products. Mixing SilvaShield
Injectable with other products cannot therefore be recommended.
PROTECTION OF LIVESTOCK: This product is highly toxic to bees exposed to direct treatment or
residues on flowering trees and shrubs. DO NOT use on trees which are likely to be used by
commercial beehives.
streams, rivers or waterways with the chemical or used containers. This product is highly toxic to
bees exposed to direct treatment or residues on flowering trees and shrubs. To minimise risk, ensure
injection occurs after flowering in species that are pollinated by bees.

Directions for use
DO NOT use on fruit or nut trees intended for food use
DO NOT use on trees likely to be used by commercial bee hives

Eucalypt trees

Fig trees

London plane trees

3-5 ml product/
10 cm dbh
(diameter at
breast height)

Use dedicated tree
injection equipment to apply the chemical. Space injection holes approximately 30cm apart around the circumference of the tree. Apply 3 - 5 ml  of chemical in each hole and seal the hole.

DO NOT reapply in the same holes.Spacing of injection holes should bevertically and horizontally staggered so that they are not aligned with other holes.
Elm trees
Elm leaf beetle
(Pyrrhalta luteola)

5 mL

Use dedicated tree injection equipment to apply the chemical. Space injection holes approximately 15 cm apart around the circumference of the tree. Spacing of injection holes should be vertically and horizontally staggered so that they are not aligned with other holes. Avoid application beneath areas of rot, wounding or other areas where vertical systemic uptake may be blocked within the tree. Where possibleinject directly in line beneath branches or limbs. Seal injection holes after application. 

DO NOT re-apply in the same holes.Patchy results may occur
3.5 mL per hole

Drill one hole per limb (or trunk in single trunked trees) using dedicated tree injection equipment. Apply 3.5 mL of chemical in each hole and seal the hole.

DO NOT reapply in the same holes. Uptake and therefore control of the pest in heavily infested heads already showing severe damage, will be slow and may be incomplete.
