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.




Add the required amount directly to the spray tank, fill with water and mix well.



Cheminova Chaser Herbicide is compatible with Cheminova Atrazine 500SC Herbicide, Cheminova Prometryn 500SC Herbicide, Cheminova Triasulfuron 750WG Herbicide, Paraquat 250 and Glyphosate Herbicide.




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) tilled-in the seeding slot before application. Alternatively, apply Cheminova Chaser immediately before sowing.








DO NOT apply to waterlogged soil.


DO NOT apply if heavy rains or storms that are likely to cause run-off are forecast within 2 days of application.


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


Resistance Warning


Cheminova Chaser Herbicide is a member of the amide group of herbicides. The product has the diverse sites of action mode of action. For weed resistance management this is Group K herbicide.


Some naturally-occurring weed biotypes resistant to Cheminova Chaser Herbicide and other group K 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 Cheminova Chaser Herbicide or other group K herbicides.


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 Cheminova Chaser 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 Cheminova representative.

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.


Safety Directions


Avoid contact with eyes and skin. Repeated exposure may cause allergic disorders. Sensitive workers should use protective clothing. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water.

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.


Envirodrum Micromatic Valve (110L):

After each use of the product, ensure that the Micromatic coupler delivery system and hoses are disconnected, triple rinsed with clean water and drained accordingly. When the contents of the Envirodrum have been used, return the Envirodrum to the point of purchase. The Envirodrum remains the property of Cheminova Pty Ltd.


Refillable containers (1000L):

DO NOT rinse empty container. Empty contents fully into application equipment. Close all valves and store as above. No other liquid, solid or pesticides product should be put into this container. When empty, return to the point of supply or Cheminova for cleaning, relabeling and refilling.


Precautions Warning

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 seedling to metabolise above normal amounts of herbicide that may accumulate in the root zone as a result of accelerated capillary movement. Cheminova Metolachlor 960 Herbicide should not be used in situations where these conditions are likely to occur.


WARNING - Brassica crops: Crop retardation may occur where Cheminova Chaser Herbicide is used on soils that have a low organic matter content and which contain more than 60% of fine sand and silt and less than 5% clay in the top 30 cm. On these soil types, use rates of Cheminova Chaser 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.


Re-entry Period

DO NOT enter treated area until spray has dried.
