General Instructions

 

Stag Herbicide is non-corrosive to equipment, non-flammable and non-volatile. The degree of weed control and duration of effect will vary with the amount of Stag Herbicide applied, soil texture, rainfall and other conditions.

 

Crop Safety

DO NOT apply Stag Herbicide to crops that are stressed by any cause such as severe weather conditions, waterlogging, drought, excessive soil acidity or alkalinity, poor nutrient status, disease, nematode or insect damage, as crop injury may result.

 

Before using Stag Herbicide on newly released crop varieties, confirm the variety tolerance with the State Department of Agriculture, Agronomist or AgVantage representative No-Till planting:

With No-Tillage planting systems that use press wheels, the risk of crop damage is increased, especially on light soil types and if heavy rain falls after spraying. USE cover-harrows after planting and before either pre or post-emergent Stag Herbicide application.

 

Barley:

Severe crop damage may result when used on barley grown on light sandy soils with low organic matter and pH over 7, especially if application is followed by heavy rainfall.

DO NOT apply to varieties Harrington and Morell.

 

Lupins:

DO NOT apply to varieties Danja, Kiev Mutant, Tanjil, Wonga, Belara, Chitick, Moonah, Quilinock, Woodjil or Albus Lupins.

DO NOT apply to Lupin crops that have received 2.5 L or more of simazine pre-seeding, or Lupin crops that are showing symptoms of simazine or atrazine damage.

 

Peas (field, processing and green):

Some varieties e.g. Dundale and Wirrega may be senstiive to Stag Herbicide.

DO NOT apply to Laura, Pennant or White Brunswick varieties as phytotoxicity may occur.

DO NOT apply to Cressy Blue peas post-emergence.

DO NOT apply any later than the one node stage to Alma and Dinkum peas.

DO NOT spray pea crops in soils or areas where collar or stem rot is likely to occur.

 

Potatoes:

DO NOT apply to crops grown on sandy soils as injury to the crop may result, appearing as chlorosis or minor necrosis.

DO NOT apply to Kurell or Bison potatoes as phytotoxicity may occur.

DO NOT apply to Atlantic and Pontiac varieties - WA only.

DO NOT use Stag Herbicide on dry-grown, non-irrigated crops.

 

Soybeans:

DO NOT use on varieties Cannapolis, Hill, Triton & Semstar as crop injury may occur.

DO NOT use on soils with a calcareous surface layer as crop injury may occur.

DO NOT apply Stag Herbicide over atrazine residues as crop injury may result.

DO NOT apply Stag Herbicide in combination with soil applied organophosphate insecticides as crop injury may result.

DO NOT apply Stag Herbicide to soils with less than 0.5 % organic matter as crop injury may result.

DO NOT apply to dryland soybeans.

DO NOT apply to soils of pH greater than 8, which are prone to waterlogging as crop injury may occur.

 

Wheat

For pre-emergent applications use ONLY on Blade & Eagle Rock varieties.

 

Vetch:

Use ONLY on Vicia sativa species e.g. Languedoc, Morava or Blanchefleur.

DO NOT use on Vicia villosa species such as Namoi, Capella, or Popany.

 

Compatibility

Stag Herbicide is compatible with the herbicides Cheminova Chlorsulfuron, Cheminova Metsulfuron, Pelican, trifluralin, Jester, Nimble, Bromoxynil + MCPA, Simazine, Yield* and Cheminova Pendimethalin 330. Stag Herbicide is compatible with the insecticides Nitofol* on potatoes, All-Mitey 290SL on peas, Cheminova Alpha-cypermethrin 100 and Cheminova Bifenthrin 100EC.

 

As product formulations can change, Stag Herbicide compatibilities with tank mix partners need to be confirmed prior to use.

 

Stag Herbicide is NOT compatible with Supracide*.

 

Mixing

 

General

Stag Herbicide is a dry flowable formulation to be mixed with water and applied as a spray.

 

Before spraying calibrate equipment to determine the quantity of water necessary to uniformly cover the measured area to be treated. Partially fill the spray tank with water. Measure the amount of Stag Herbicide required for the area to be sprayed. Add the correct amount of Stag Herbicide to the spray tank with the agitation system engaged. Top up to the correct volume with water. THE MATERIAL MUST BE KEPT IN SUSPENSION AT ALL TIMES BY CONTINUOUS AGITATION. In tank mixes Stag Herbicide must be in suspension before adding the companion herbicide, insecticide or liquid fertiliser.

 

Application

 

General

Best results are obtained if treatment is made to moist soil and moisture is supplied by rainfall or sprinkler irrigation (6 - 12 mm) within 2 weeks after application. If heavy rains occur soon after application, injury to the crop may result.

 

Aerial Application - (Qld only)

Peas - apply in a minimum of 20 L water per hectare.

Potatoes - apply in a minimum of 50 L water per hectare.

Avoid overlapping of spray swath. Avoid spraying in still conditions and in wind likely to cause drift.

 

Pre-emergence and Post-emergence (to crop)

Stag Herbicide should be applied when weeds are in the young seedling stage (no more than 3 true leaves). Under dry conditions there is no root uptake of Stag Herbicide and results against grass weeds and Wireweed (Hogweed) will be poor. Except for small areas, use fixed boom power sprayers set at 200 - 300 kPa (for tomatoes DO NOT exceed 200 kPa) and fitted with fan nozzles. Apply a minimum of 80 - 100 L prepared spray per hectare. Openings in screens should be equal to or larger than 50 mesh. Agitate by mechanical or hydraulic means in the spray tank. When spraying avoid overlapping. Shut off spray booms whilst starting, turning, slowing or stopping otherwise crop injury may result.

 

Pre-plant incorporated - Soybeans only

Stag Herbicide alone or in combination with trifluralin

Spray anytime from 4 weeks before sowing until just before sowing.

Use fixed boom power sprayers set at 200 - 300 kPa and fitted with fan nozzles. Use 120 - 500 L water per hectare. Openings in screens should be equal to or larger than 50 mesh. Agitate by mechanical or hydraulic means in the spray tank. When spraying avoid overlapping. Shut off spray booms while starting, turning, slowing and stopping otherwise crop injury may result.

 

Stag Herbicide alone

If possible spray and incorporate within the same operation. If not possible incorporate spray within 24 hours of application using Go-devil or Lilliston cultivators set to work 5 cm deep.

 

Stag Herbicide plus Trifluralin

After spraying mix into soil within 4 hours. Spray and incorporate during the one operation if possible. (Refer to trifluralin label for specific incorporation details).

 

Sprayer Cleanup

Thoroughly clean all traces of Stag Herbicide and or trifluralin from application equipment immediately after use. Flush tank, pump, hoses and boom with several changes of water after removing nozzle tips and screens (clean these parts separately).

 

Restraints DO NOT apply Stag Herbicide to crops that are stressed by any cause such as severe weather conditions, waterlogging, drought, excessive soil acidity or alkalinity, poor nutrient status, disease, nematode or insect damage, as crop injury may result.

 

Resistance Warning Stag Herbicide is a member of the Triazinone group of herbicides. The product has the inhibition of photosynthesis at photosystem II mode of action. For weed resistance management, the product is a Group C herbicide.

 

Some naturally occurring weed biotypes resistant to Stag Herbicide and other Group C herbicides are known to exist. They can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Stag Herbicide or other Group C herbicides.

 

Annual Ryegrass biotypes resistant to diclofop-methyl and other 'grass specific' herbicides are often also resistant to Stag Herbicide. Before using Stag Herbicide on a population resistant to 'grass specific' herbicides, have a resistance test conducted to ensure that it is still susceptible to Stag Herbicide.

 

Since the occurrence of resistant weeds is difficult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of Stag Herbicide to control resistant weeds.

Large numbers of healthy surviving weeds can be an indication that resistance is developing. Efforts should be made to prevent seed set of the survivors.

 

DO NOT make more than one application of Group C herbicides to a crop in the same season, either pre-sowing incorporated by sowing or post crop and weed emergence. If the user suspects that a Group C resistant weed is present, Stag Herbicide or other Group C herbicides should not be used.

 

Strategies to minimise the risk of herbicide resistance are available. Consult your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or local Cheminova representative.

 

Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with the chemical or used containers.

 

Protection of crop, native and other non-target plants

DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby susceptible plants / crops, cropping lands or pastures.

 

RECROPPING

DO NOT plant treated areas to sensitive crops, such as brassicas, sunflowers, beetroot, cucurbits, lettuce or onions, for at least 6 months following application of Stag Herbicide, as crop injury may result. Thoroughly work the soil prior to the planting of these crops.

 

Tomatoes

DO NOT follow Autumn plantings of tomatoes with crops of cucurbits or capsicums in the same season.

 

Safety Directions

 

Harmful if inhaled or swallowed. Will irritate the eyes and skin. Avoid contact with eyes and skin. Do not inhale dust or spray mist. Repeated minor exposure may have a cumulative poisoning effect. When opening the container and preparing spray wear cotton overalls buttoned to the neck and wrist, a washable hat, elbow-length PVC gloves and a face shield or goggles. Wash hands after use.

 

Storage

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

 

Disposal

These containers can be recycled if it is clean, dry, free of visible residues and has the drumMUSTER logo visible. Triple or preferably pressure rinse containers before disposal. Dispose of rinsate by adding it to the spray tank. DO NOT dispose of undiluted chemicals on site. Wash outside of the container and the cap. Store cleaned container in a sheltered place with cap removed. It will then be acceptable for recycling at any drumMUSTER collection point or similar container management program site. The cap should not be replaced but may be taken separately.

If not recycling, break, crush, or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the empty containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt.
