Hexmac 750SG Herbicide

Tips For Use

Notice (NSW Only):

• With the exception of regrowth less than 5 years old and under three metres tall, the clearing of more than five hectares of trees by aerial or ground 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:

• Hexmac 750SG Herbicide is an effective foliar contact and soil-active residual herbicide. 
• Use sufficient water for thorough, uniform coverage. 
• For best foliar and residual control, apply as a post-emergent spray during the period of active plant growth and when the air temperatures are 25°C and above. 
• Applications when vegetation is dormant, semi-dormant, under moisture stress or during the winter months may not be as effective.
• In temperate winter rainfall areas where temperatures are generally below 25°C during the period of active plant growth, the foliar effect may be slow to appear. 
• In these areas, herbicide activity is more dependent on root absorption.
• For residual control, sufficient rainfall is required after treatment to promote root absorption by the weeds.
• Results obtained may vary with the amount of chemical applied, rainfall, air temperature, soil type and other conditions.
• All use rates of the product are expressed as overall rates. For band treatment, use proportionately less, i.e. use one-third of the overall rate when treating one-third of the area.
• Do not apply Hexmac 750SG Herbicide during periods of intense rainfall, when wind speed exceeds 30 kph (for ground application) or when wind speed exceeds 20 kph (for aerial application).
• Do not broadcast this product where there is no vegetation or slash or on uncultivated areas or non-mounded or bare ground on slopes.
• Do not make more than one application of an Inhibitor of photosynthesis at photosystem II herbicide in the same season.

Equipment and Application:

• Hexmac 750SG Herbicide is a dry flowable formulation. 
• The product is mixed with water and applied at recommended rates with either ground or aerial equipment (dependent on use pattern).
• Partially fill the spray tank with water and add the correct amount of the product for the area to be sprayed with the agitation system engaged. 
• Top up to correct volume with water, and for best results, keep the spray solution agitated whilst spraying. 
• The material must be kept in suspension at all times by continuous agitation. 
• To prevent nozzle blockage, strainer and nozzle screens should be 50 mesh or coarser.

Industrial Weed Control:

Ground Application only

• Apply in 100 to 400 L/ha with a properly calibrated boom or 2000 – 4000 L/ha with hand spray equipment.
• A non-ionic surfactant/wetting agent (such as BS 1000) may be added at the rate of 250 – 500 mL/100 L of spray (for a surfactant containing 100 % active constituent) for improved wetting.

Pinus Radiata:

Ground Application

• Apply in 100 to 400 L/ha with a properly calibrated boom.

Forestry Spotgun

• See Directions for Use – Critical comments

Aerial Application

• Apply a minimum of 20 L of water for every 1 kg of product used, eg, 5 kg in 100 L of water per hectare.
• Use a surfactant/wetting agent for pre-planting applications only, by either ground or aerial equipment. 
• Do not add a surfactant if the spray is to be applied over the top of Pinus radiata trees.
• A non-ionic surfactant/wetting agent (such as BS 1000) may be added at the rate of 250 – 500 mL/100 L of spray (for a surfactant containing 100 % active constituent) for improved wetting.

Protection of Crops, Native and Other 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, 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 roots of desirable trees or plants may extend.
• Do not drain or flush spray equipment near desirable trees or in areas where their roots may extend.
• Do not apply under windy conditions and in areas where spray drift could damage valuable plants.
• Do not within 25 m of a recognised waterway, or further if native riverbank vegetation may be damaged (see Protection of Native and other Non-target Plants).

Protection of Wildlife, Fish, Crustaceans and Environment.
Do not contaminate ponds, streams, rivers, watercourses or drains with the chemical or used containers.
Do not apply within 25 m of a recognised waterway, or further if native riverbank vegetation may be damaged (see Protection of Native and other Non-target Plants).

Protection of Livestock.

• Keep stock away from treated areas.

Storage:

• Store in the closed, original container in a dry, well-ventilated area, as cool as possible out of direct sunlight. 
• Do not store or expose the product to wet conditions.
