Hatchet Extra Herbicide

Tips For Use

General Instructions:

• Aminopyralid and picloram remain active in the soil for extended periods depending on the rate of application, soil type (clay content), rainfall, temperature, humidity, soil moisture and soil organic matter.
• Refer to plant back period tables in the directions of use that show plant back periods to particular crops following the application of Hatchet Extra in different areas/situations of Australia.

Application in Woody Weed Situations:

• Weeds need to be actively growing for herbicides to have optimum effect.
• Delay treatment until all regrowth has had time to grow to approximately 1 metre in situations that have been bulldozed, slashed, burnt, ploughed or areas having a previous chemical treatment.

Application Of Woody Weeds:

• High Volume Spraying – Thorough coverage of foliage to the point of run-off is essential. However, excess spraying should be avoided, which is a waste of chemicals.
• Knapsack & 12 Volt Sprayer Packs – Apply the recommended spray mix to give full coverage of leaves and stems. Only recommended for the control of herbaceous weeds, such as capeweed, fireweed and spear thistle, and woody weeds that are not regrowth less than 60 cm high or 60 cm diameter.
• Aerial Application – Apply Hatchet Extra in 200L of water/Ha using an aircraft to apply 100L per pass on a double overlap pattern using nozzle configurations to produce coarse to very coarse droplets.
• Low Volume High Concentrate Application Techniques – Good control will be achieved, similar to high volume application, where bush size enables good coverage of the entire bush. Use a marking agent, as recommended by the equipment manufacturers, to check spray coverage.
  • Gas-Powered Gun: Apply 50mL shots to obtain uniform coverage of 4m² to 5m² of bush surface area. This relates to 20 droplets/cm2 of the leaf surface.
  • Sprinkler Sprayer: This technique involves using a micro sprinkler that is connected to a hollow fibreglass rod attached to a pneumatic knapsack sprayer. Use at low pressures (50 to 200kPa) and apply with a slow sweeping action over the top of the plants, ensuring even coverage of the leaves.
• Boom Application – Application in a minimum spray volume of 200L/ha for Galenia and St John’s wort and 600L of water/ha for Sicklepod. Flat fan nozzles are recommended, using pressure in the range of 200-300kPa. Boom height must be set to ensure a double overlap of nozzle patterns.

Compatibility:

• Follow any regional restrictions, and all directions and restrictions on the label, of any chemical mixed with Conquest Hatchet Extra Herbicide EC (eg. 2,4-D amine).

Mixing:

• Mix only with water.
• Half-fill the spray unit with water, and add the required amount of Hatchet Extra. 
• Add the remaining water while the agitator is running. 
• If required, then add spray oils or wetters (surfactants). 
• Maintain mechanical or by-pass agitation in the spray tank during spraying. 
• Only mix sufficient solution for immediate daily use and avoid storing.

Restraints: 

• Do not apply to weeds that may be stressed (not actively growing) due to prolonged periods of extreme cold, moisture stress (water-logged or drought-affected), poor nutrition, presence of disease, damage or previous herbicide treatment, as reduced levels of control may result.
• Do not spray if rain is likely within one hour or if foliage is wet from rain or dew.
• Do not burn off, cut or clear blackberry or other woody weeds for at least six months after spraying.
• Do not apply by aerial application in wind in excess of 15km/hr and air temperatures above 35°C.

In areas prone to flooding, treatment should commence after any annual flooding, as such areas that flooded within 9 months following application may have reduced results.

Spray Drift Restraints:

• Specific definitions for terms used in this section of the label can be found at apvma.gov.au/spraydrift
• Do not allow bystanders to come into contact with the spray cloud.
• Do not apply in a manner that may cause an unacceptable impact on native vegetation, agricultural crops, landscaped gardens and aquaculture production or cause contamination of plant or livestock commodities outside the application site from spray drift. Wherever possible, correctly use application equipment designed to reduce spray drift and apply when the wind direction is away from these sensitive areas.
• Do not apply unless the wind speed is between 3 and 20 kilometres per hour at the application site during the time of application.
• Do not apply if there are hazardous surface temperature inversion conditions present at the application site during the time of application. Surface temperature inversion conditions exist most evenings one to two hours before sunset and persist until one to two hours after sunrise.

Other Limitations: 

• In Tasmania, For Blackberry: Do not treat bushes carrying mature or near mature fruit.
• For Native Vegetation: Use of Hatchet Extra Herbicide on native vegetation must be done in accordance with State and/or Local legislation.

Protection Of Crops, Native And Other Non-Target Plants:

• Crops susceptible to Hatchet Herbicide include, but are not limited to, peas, lupins, lucerne, navy beans, peanuts, soybeans and other legumes, cotton, flowers, fruit, hops, ornamentals, shade trees and Pinus spp., potatoes, safflower, sugar beet, sunflowers, tobacco, tomatoes, vegetables and vines.
• Hatchet Extra Herbicide is damaging to susceptible crops during both growing and dormant periods. 
• Grasses are normally unaffected and are established quickly after treatment.
• Picloram and aminopyralid, two of the active constituents in this product, can remain in the soil for extended periods depending on soil type and application rate, rainfall, temperature, humidity, soil moisture and soil organic matter.
• Do not apply under weather conditions or from spraying equipment, which may cause spray drift onto nearby susceptible plants/crops, cropping lands, pastures, watercourses, or native vegetation.
• Do not allow physical spray to drift onto waterways, native vegetation, and susceptible crops.
• Do not apply close to or in areas containing roots of desirable vegetation, where treated soil may be washed onto areas growing (or areas to be planted with) desirable plants.
• Do not apply on sites where surface water from heavy rain can be expected to run off to areas containing, or to be planted with susceptible crops or plants.
• Do not move soil, which may have been treated, to areas where desirable plants are to be grown.

Management Of Residues In Compost, Mulches And Animal Waste:

• Do not cut pasture or hay for silage production within six (6) months of application, where it is intended for use off-farm.
• Do not use treated plant material to make compost, mulches or mushroom substrates. 
• Do not send straw from treated pastures off-farm for the purposes of animal bedding. 
• Do not send animal manure, dairy shed or feed pad effluent that has been collected from animals grazing or fed pastures treated within the last six (6) months off-farm. 
• Spreading/irrigating this manure/effluent may cause damage to clover and other susceptible plants.
• Do not send compost made from animal waste that has been collected from animals grazing or fed pastures within the previous 6 months off-farm. Such compost may cause damage to clover and other susceptible plants.
• Do not apply animal waste (e.g. manure, slurry) collected from animals grazing or fed pastures treated within the previous six (6) months to susceptible plants or land used to grow susceptible plants.
• Do not grow susceptible plants within the relevant plant back period in fields treated with manure/effluent from farms where animals have grazed or been fed treated pasture until a field bioassay shows there are no residues in the soil at levels injurious to the susceptible plants (see crop rotation section).
• To promote herbicide decomposition, manure should be evenly incorporated into the soil surface. 
• The breakdown of residues in decomposing plants or manure is more rapid under warm, moist soil conditions and may be enhanced by supplemental irrigation.

Protection Of Livestock:

• Poisonous plants may become more palatable after spraying and stock should be kept away from these plants until they have died down.
• Many plants remain poisonous after death, and stock should not be allowed access it, as there is a likelihood that they may graze the dead material. Such material should be burnt if possible.

Protection Of Wildlife, Fish, Crustaceans And Environment:

• Do not contaminate streams, rivers, or watercourses with the chemical or used containers.

Storage:

• Store in the closed, original container in a cool, well-ventilated area. 
• Do not store for prolonged periods in direct sunlight.

Safety Directions:

• It will irritate the eyes and skin. 
• Avoid contact with eyes and skin. 
• When opening the container and preparing spray, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and elbow-length chemical resistant gloves and face shield or goggles.
• When using the prepared spray with hand-held application equipment, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and elbow-length chemical-resistant gloves. 
• After each day of use, wash gloves, face shields or goggles and contaminated clothing. 
• Wash hands after use.
