Tressel 250 SL Herbicide (Hexazinone)

Tips For Use

Restraints:

• Do not use on lawns, walkways, driveways or tennis courts.
• Do not apply more than once per calendar year.
• Do not apply if heavy rain or storms are forecast within 3 days.
• Do not irrigate to the point of field runoff for at least 3 days after application.
• Do not use it in water-logged areas.

Sugarcane Restraints:

• Do not use in plant cane prior to hilling cultivation
• Do not apply by aircraft, misting machines or hand-held ultra-low volume controlled droplet applications (CDA units).
• Do not apply to fields where the slope exceeds 5%.
• Do not spray over sugarcane or allow excessive spray contact as crop injury may result.
• Do not use on light sandy soils as injury to cane may result.
• Do not use in young plant cane.
• Do not use equipment or spraying methods that cause spray or spray drift to contact the growing point of the sugarcane.
• Do not spray plants that are waterlogged, or under stress of any kind, or covered with soil or dust.
• Do not spray plants covered with heavy dew, but rain following spraying will not affect results.

Limitation Notice (NSW Only):

• With the exception of regrowth less than five years old and under 3 metres tall, the clearing of more than five hectares of trees by aerial, ground or spot-gun application in NSW is prohibited, unless specifically authorised by permit.
• This restriction does not apply to woody weeds and stem injection of trees.

General Instructions:

• This product is foliar and root-absorbed and will give residual soil activity.
• For best foliar and residual control, apply during periods of active plant growth.
• Application when vegetation is dormant, semi-dormant, under moisture stress or during winter months may not be as effective.
• In temperate winter rainfall areas where temperatures are generally below  5°C during periods of active growth, overall effect may be slower to appear.
• For best control of perennials, apply during the months of spring in these areas.
• In WA and SA, apply Tressel Herbicide only during April-August when adequate rainfall is expected.
• Sufficient moisture is required after treatment to promote root absorption by the weed species.
• Do not apply Tressel 250 SL Herbicide during periods of intense rainfall or under conditions that will cause drift of movement to non-target areas.
• On slopes of 20% to 30% apply Tressel 250 SL Herbicide by strip, spot or stem injection applications only.
• On slopes, greater than 30%, apply by sport or stem injection application only.
• The L/ha rates in the directions for use tables refer to sprayed hectares.
• Visible symptoms and degree of effectiveness will vary with temperature, soil types, rainfall, soil moisture and stress level of plants.

Important Points:

• Hexazinone may be used all year round but since rainfall is required to move it into the soil and to promote active plant growth, quickest results are obtained when it is applied to moist soil and rainfall follows soon after application.
• Hexazinone can remain on the soil surface during extended periods of dry weather and when rain comes there is little loss of control.
• Do not apply, flush or clean equipment near desirable vegetation, as Hexazinone Herbicide residue may affect them. 
• As a general rule, you should not apply Hexazinone Herbicide closer than twice the height of trees and vegetation you do not wish to control.

Control Times:

• Once in the soil, Hexazinone Herbicide is taken up by the roots and translocated within the plant.
• It works by inhibiting the photosynthesis process, starving the plant to death. 
• This is a slow process.
• The plant may not appear affected for a while (particularly under dry conditions) and may defoliate and re-foliate several times before it completely dies.
• Complete control normally occurs within 12 months; however, under adverse conditions, it sometimes may take longer.

Precautions:

• Do not enter treated areas until the spray has dried, unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical resistant gloves.
• Clothing must be laundered after each day’s use.

Protection of crops, native and non-target plants:

• The product may kill many trees and other desirable plants if not correctly applied.
• Do not apply on or near desirable trees or other plants (except as recommended for crop use), or on areas where their roots may extend, as guidance, this is two times their height or more depending on the species and other conditions.
• Do not apply in areas where a surface flow of water could wash the chemical into areas where the roots or desirable trees or plants may extend.
• Do not drain or flush spray equipment, Spotgune or Stem injector near desirable trees or in areas where their roots may extend.
• Do not apply under weather conditions or from spraying equipment that may cause spray drift onto nearby susceptible plants/crops, cropping lands or pastures.

Protection of Livestock:

• a) Spotgun and Stem Injection Applications – Stock does not need to be moved away from Spotgune and Stem Injection treated areas.
• b) Foliar Spray Applications – Keep stock away from sprayed areas.

Protection of Wildlife, Fish, Crustaceans and the Environment:

• Do not contaminate streams, rivers or watercourses with the chemical or the used containers.
• The tank mix with Capo Herbicide (Glufosinate) may be toxic to native mammals.
• Do not apply tank mix with AC Capo on sites where vulnerable, threatened, endangered or critically endangered mammals are known to occur.

Storage:

• Store in the closed, original container in a cool, well-ventilated area.
• Do not store for prolonged periods in direct sunlight. Do not use or store at temperatures of 0°C, or below, as the product will freeze.
• Flammable, keep away from heat, sparks and naked flame.
• Keep from contact with fertilisers, insecticides, fungicides and seeds.
• Do not reuse the container.

Safety Directions:

• It will irritate the eyes and skin.
• Avoid contact with the eyes and skin.
• Do not inhale spray mist.
• When using it together with other products, consult their label safety directions.
