Directions Of Use

Use Rate & General Instructions:

Restraints:

  • SilvaShield is intended to be applied undiluted (do not attempt to dilute product with water).
  • Space injection points evenly around the circumference of the tree.

  • In all situations, application post-flowering is recommended.
SITUATION PEST RATE CRITICAL COMMENTS
Eucalypt trees Thaumastocoris bugs 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 be vertically and horizontally staggered so that they are not aligned with other holes.

London plane trees Sycamore lace bug (Corythucha ciliata) 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 be vertically and horizontally staggered so that they are not aligned with other holes.
Elm trees Elm leaf beetle (Pyrrhalta luteola) 5 mL product/10cm dbh 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 possible inject directly in line beneath branches or limbs. Seal injection holes after application. DO NOT reapply in the same holes. Patchy results may occur if injection holes are not well placed.
Pandanus Flatid 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.

    After injecting Silvashield into the drilled hole, you can plug the hole using a softwood, i.e. balsa or cork, to prevent the product from expelling or drying out.

    Asked by Alex on August 13, 2023 8:47 am
    Answered by the admin

    Silvashield Injectable Tree Insecticide is not registered or recommended to control White Wax Scale or White Louse Scale (Unaspis citri). We would suggest considering other options such as Bugmaster Flowable Insecticide (registered for the control of white wax scale on ornamentals), Lime Sulphur Fungicide & Insecticide (White Louse Scale), Spectrum 200 SC Insecticide (soft-scale insects) or White Oil Insecticide (Scale Insects on ornamental trees). Always read the 'directions for use' to confirm suitability to your situation.

  7. Q Would Silvashield Injectable Tree Insecticide be suitable for borers in a metrosideros hedge?
    Asked by Matt on May 15, 2023 7:48 pm
    Answered by the admin

    Silvashield Injectable Tree Insecticide is not explicitly registered to control pests or be used in metrosideros hedges, so results after application can't be guaranteed. As Silvashield Injectable Tree Insecticide is a systemic insecticide designed to target insect pests via trunk or stem injection, it may be worthwhile conducting an 'off-label' trial on the metrosideros hedges. Alternatively, a soil drench application of Surefire Spectrum 200SC Insecticide may be trialled.

    Silvashield Injectable Tree Insecticide is only registered to control Leaf Blister, Sawfly - Larva & Thaumastocoris Bugs when used on Eucalyptus Tree. These may have been the only pests included in the testing stage of the product. However, as Lerps/Psyllidae are not included on the product's label, there is no control guarantee. An off-label trial is the only way to determine if it affects these pests.

    Asked by John Monty on October 25, 2022 8:17 am
    Answered by the admin

    Holes should be drilled deep enough to permit the transport of Silvashield Injectable Tree Insecticide upwards in the vascular tissue (sapwood - xylem) and large enough to allow the injection applicator nozzle to fit.  If you require more specific application information other than what is listed on Silvashield Injectable Tree Insecticides directions for use, we recommend contacting the product manufacturer, Environmental Science Australia - https://www.au.envu.com/sitecore-forms/contact

Tips For Use

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.

Do not use on fruit or nut trees intended for food use. Do not use on trees likely to be used by commercial beehives (see additional information on label).

First Aid:

If poisoning occurs contact a doctor or Poisons Information Centre. Phone Australia 131 126.
For further information, refer to the Safety Data Sheet (SDS).

Comparison of Trunk Injection vs Soil Injection:

To compare the amount of active ingredient applied between soil injection with a suspension concentrate and trunk injection with SilvaShield

For a 50 cm diameter tree, at label rates, 28 g of active ingredient would be required via soil injection whereas only 3-5 g of active ingredient would be required via trunk injection

FAQ’s:

How Easy Is It to Inject Trees?

Appropriate injection equipment is necessary in order to efficiently and effectively use this product. A certain level of expertise is also required to ensure that injection is carried out properly. It is recommended that trained arborists or otherwise experienced or qualified persons carry out the treatment with this product.

How Long Does It Take to Inject a Large Tree?

Depending on the application equipment used and the level of expertise of the person carrying out the treatment a large tree (eg. 100 cm in diameter) can take as little as 10 minutes to treat.

Does Injection Damage the Tree?

The chemical itself has been shown not to cause significant damage to a wide range of tree species when injected directly using a number of different injector systems. Trials have shown that compartmentalisation of the injection points occurs after application and there is no evidence to suggest that direct trunk injection causes any long-term structural or physiological damage to the tree.

How Does Trunk Injection Protect the Rest of The Tree?

The Active Ingredient in Silva Shield is imidacloprid which is taken up systemically through the tree vascular system and distributed to areas such as the leaves.

How Long Does Treatment with Silvashield Protect the Tree?

Trials with eucalypts and thaumastocoris have shown that a single treatment of SilvaShield can control insect numbers for a period of 3 years. The length of protection conferred against other pests in other tree species has not been determined but there is evidence from other applications to suggest that extended protection could be expected.
