Hatchet Herbicide (Triclopyr & Picloram)

Tips For Use

Application Timing for Best Results:

• In General, Smaller Weeds Are Easier to Control than Large Ones. 
• Hatchet Herbicide is most effective when applied to weeds that are not stressed due to lack of moisture, excessive heat, insect or pathogen (such as rust) damage, etc. and are actively growing. Actively growing weeds will draw the chemical into the vascular system and transport it through the stems and down to the roots to ensure maximum efficacy.
• Hatchet Herbicide needs to penetrate into the leaves of treated weeds before any rainfall occurs so do not make applications if rain is possible before the spray is completely dry – usually one hour. Similarly, avoid application if the leaves are wet from rainfall or dew.
• Once the weeds have been sprayed leave them undisturbed so that the chemical is able to move throughout the leaves, stems and roots and provide complete kill. Disturbing the weeds by slashing, burning, mulching, etc. before the chemical is fully distributed will compromise the control achieved. We recommend that blackberries and other woody weeds not be disturbed for six months after spraying to maximise the performance of Hatchet Herbicide.

Application Methods:

• Apply as a foliar spot spray to completely wet all leaves and stems. Coverage should be to the point of run-off in that the chemical mix is just beginning to drip from the leaves once the spraying is completed. Think of painting a wall and use that motion in your spray action to achieve full coverage of the foliage, then use a more directed stream to thoroughly treat the stems and canes.
• This type of application is called high volume spraying as you are applying a large amount of spray mixture to the target weeds. Provided that good coverage of the target weed is possible, high volume spraying can be completed using a variety of equipment – from a small hand pump unit to a knapsack sprayer through to a large motorised pump and handgun unit.
• With a foliar spray you are looking to capture enough chemical on the foliage to kill not only the above-ground portion of the weed but all of the root mass as well, so good coverage is essential. If you are spraying very large weeds like blackberries that are several years old, ensure that canes on the inside as well as outside of the foliage mass receive direct contact with the applied spray. 
• As a guide, one hectare of blackberries 1–2 metres in height will typically require a spray volume of 3000–4000 litres to be thoroughly covered, whilst the same area of a small herbaceous weed such as ragwort will require 500–1000 litres. 
• Always refer to the label & directions before using, as some conditions apply to certain weeds, areas of use etc.  Further details of use can be found in the Direction of Use section on the Product Label.
• Read all product literature for further instructions and consult directions for use label supplied with product prior to use.
