General Instructions

 

Uses

The product is a short residual pre-emergent herbicide for the control of many important annual grasses and broadleaf weeds in the crops nominated. The product does not control the important broadleaf weeds in maize, sweet corn and Concep II treated sorghum, but when mixed with Flowable Atrazine control of many important annual weeds and grasses is obtained without the problem of carryover of herbicides affecting succeeding crops. The product acts mainly through shoot (coleoptile) absorption. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the top 3 to 4cm of soil, where it must be present at the time of weed germination.

 

Restraints

 

DO NOT apply to waterlogged soils

DO NOT apply if heavy rains or storms that are likely to cause runoff are forecast within 2 days of application

DO NOT irrigate to the point of run off for at least 2 days after application

 

Withholding Period

 

Canola: DO NOT GRAZE TREATED FIELDS FOR 10 WEEKS AFTER APPLICATION.

Green beans: DO NOT HARVEST BEANS FOR 8 WEEKS AFTER APPLICATION 

DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 10 WEEKS AFTER APPLICATION.

Pastures: DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 13 WEEKS AFTER APPLICATION.

Sweet potatoes: DO NOT HARVEST, GRAZE OR CUT FOR STOCK FOOD FOR 23 WEEKS AFTER APPLICATION.

Wheat, Barley, DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 8 WEEKS AFTER APPLICATION.

Oats, Triticale: HARVEST withhold for all other crops: NOT REQUIRED WHEN USED AS DIRECTED.

FORAGE withhold for all other crops Except Sweet potatoes): DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 13 WEEKS AFTER APPLICATION.

 

Application

 

Ground application: Apply in a minimum of 60 L/ha of water. DO NOT apply by aircraft.

 

Mixing

 

Fill the spray tank to one quarter full. Then add Chaser S Herbicide to make up the final spray volume. Pour Chaser S Herbicide into the stream of oncoming water. Good agitation at the time Chaser S Herbicide is added to the tank will ensure good mixing. 

 

When Tank Mixing: Wettable powder or water dispersible granule formulations should be added to the tank first, followed by suspension concentrates (flowables) water solution salts then Chaser S Herbicide or other emulsifiable concentrate formulations. Maintain thorough agitation during mixing and application. Agitate tank mixes vigorously if allowed to stand.

Note: Tank mix spray solution should NOT be left standing in the vat overnight.

 

Compatibility

 

Chaser S Herbicide is compatible with Prometryn Flowable Liquid Herbicide, Fluometuron 500 Flowable Herbicide, Prometryn/Fluometuron 500 Liquid Herbicide, Atrazine Flowable Herbicide, Logran®, Paraquat 250 and Glyphosate. 

 

WARNING – Cotton:

 

DO NOT use when planting into dry soil or soil with marginal moisture. Under dry planting conditions heavy rain or flood irrigation soon after planting, together with below average soil temperatures, can result in crop injury, due to the inability of the germinating plant being able to metabolise above normal amounts of the herbicide that may accumulate in the root zone as a result of accelerated capillary movement Chaser S Herbicide should not be used in situations where these conditions are likely to occur.

 

WARNING – Brassica crops:

 

 

Crop retardation may occur where Chaser S Herbicide is used on soils that have a low organic matter content and which contain more than 60% of fine sand and silt. On these soil types, use rates of Chaser S Herbicide towards the lower end of the rate range and apply onto moist soil. Irrigation after application should be limited to no more than 25mm. DO NOT use more than once per year.

 

Zero tillage (Canola, Barley, Oats, Wheat, Triticale):

 

When sowing using knife points and zero tillage, and leaving a seeding slot, DO NOT apply post-seeding unless harrows (or similar) have filled in the seeding slot before application. Alternatively apply Chaser S Herbicide immediately after seeding.

 

Resistance Warning 

 

Chaser S Herbicide is a member of the amides group of herbicides with diverse sites of action. For weed resistance management this is Group K herbicide. Some naturally-occurring weed biotypes resistant to Chaser S Herbicide and other amide herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Chaser S Herbicide or other amide herbicides.

Since the occurrence of resistant weeds is difficult to detect prior to use, Crop Care Australasia Pty Ltd accepts no liability for any losses that may result from the failure of Chaser S Herbicide to control the resistant weeds.

Advice as to strategies and alternative treatments that can be used should be obtained from your local supplier, consultant, local Department of Agriculture, Primary Industries Department or an Crop Care representative.

 

Precautions

 

Re-entry Period: DO NOT enter treated area without protective clothing until spray has dried.

 

Protection of Crops, Native and Other Non Target Plants

 

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

DO NOT plant crops other than broccoli, brussels sprouts, cabbages, cauliflowers, cotton, maize, peanuts, soybeans, sunflowers, sweet corn, tobacco, or Concep II treated sorghum within six months of application of Chaser S Herbicide.

 

Protection of Livestock

 

Do not graze or cut sweet potato leaves for stock food.

 

Protection of Wildlife, Fish, Crustaceans and Environment

 

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

DO NOT apply under meteorological conditions or from spraying equipment which could be expected to cause spray drift onto adjacent areas, particularly wetlands, water bodies or watercourses.

 

Storage and Disposal

 

Store in the closed, original container in a dry, cool, well ventilated area out of direct sunlight. 

Triple or preferably pressure rinse containers before disposal. Add rinsings to the spray tank. 

DO NOT dispose of undiluted chemicals on-site. If recycling, replace cap and return clean containers to recycler or designated collection point. 

If not recycling, break, crush, or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the 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.

For refillable containers: Empty contents fully into application equipment. Close all valves and return to point of supply for refill or storage.

 

Safety Directions

Will damage the eyes. Avoid contact with eyes and skin. Repeated exposure may cause allergic disorders. Sensitive workers should use protective clothing. 

When opening the container and preparing spray wear, cotton overalls buttoned to the neck and wrist (or equivalent clothing), a washable hat, elbow-length PVC gloves and goggles. 

When using the prepared spray wear, cotton overalls buttoned to the neck and wrist (or equivalent clothing), a washable hat, elbow-length PVC gloves and face shield or goggles

If product in eyes, wash it out immediately with water. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day’s use, wash gloves, face shield or goggles and contaminated clothing.
