- ENVIRONMENTAL SAFETY
“I loosed an arrow unto the air, it came to earth, I know not where” Henry Wadsworth Longfellow
Whilst competent operators can under ideal weather and machine conditions usually place most of the chemical applied by airborne spray on the target plant, some will always be carried away to contaminate the surrounding environment. Chemical injected into trees via properly designed systems, with effective injection site sealing poses almost zero risk of chemical escape.
- MORE TARGET SPECIFIC
Beneficial insects, mammals and birds are generally unaffected by internal tree application of pesticides, only insects consuming plant tissue or fluids are at risk. This characteristic is particularly useful in public place situations.
- GREATER PERSISTENCE
Numerous trails with a wide range of pesticides show much longer periods of activity of material injected as compared to the same material sprayed on the outside of trees due, amongst other factors, to protection from rain and surface water as well as the degrading effects of sunlight. As examples, dimethoate injected into eucalypts gives 6 to 12 weeks protection against lerps, Bayer Imidacloprid injected into pandanus palms has given around 2 years protection against the leaf hopper jemmella australiae.
- CHEMICAL MINIMIZATION
Numerous tests indicate that substantially less quantity of the same chemical is required to achieve the same or better result when injected as against air born spraying or ground application.
- PUBLIC AND OPERATOR SAFETY
By the elimination of drift and the surface application of pesticides, risks of contact by the general public, operators and other workers is greatly reduced. In one trail report by the Queensland Dept. of Natural Resources a researcher accessed the Sidewinder Injection System as the safest method of application of herbicides available.
- REDUCED RISK OF LITIGATION
With the pesticide sealed within the plant, elimination of drift and the possibility of ground or surface water contamination, potential for litigation is low. Tree injection is widely used by government departments in such places as National Parks, suburban parks, street fronts etc.
- USE OF TRAP TREES
Injection of perimeter or windbreak trees of types preferred by specific by specific insect pests offers further opportunities to both reduce the amount of insecticide used and complete elimination of residue in the crop.
- PUBLIC ACCEPTABILITY
Increasing public pressure is making it ever more difficult for horticulturists and contractors generally to apply pesticides. This trend will continue. The writers experience during numerous exercises of injecting trees in public places has been that when the operator explains the process to people without exception approval is immediate.
- COMPATIBILITY WITH INTEGRATED PEST MANAGEMENT
As little if any injected pesticide ends up on the surface of leaves, beneficial bugs are at low risk.
- INJECTABLE PESTICIDES
All horticultural chemical types can be injected, including insecticides, fungicides, herbicides, growth regulators, trace elements and certain combinations of same.
NOTE: Always check with your local agricultural authority re chemical registration before using.
Use of a pesticide other than as indicated on the suppliers label, or an “Off Label Permit” is illegal.
