General Instructions

For best results apply when growing conditions are good to weeds and crop which are not stressed from factors such as severe frost, waterlogging or dry conditions. Avoid applying to crops which are covered in dew or frost. Wild oats germinating after application will often be stunted and will not seriously compete with the crop.


Results indicate that a spray mixture may be left overnight without loss of efficiency if spraying cannot be completed but it is recommended that the spray mixture be used on the same day it is prepared.



Fill the spray tank to about two thirds full with clean water and then add the required amount of Cheminova Diclofop Methyl Herbicide. Add the reminder of the water with agitation system engaged. If a wetting agent is required add this last to prevent excessive foaming.



Aim to apply this product to base of weeds to ensure penetration.



  1. For broadleaf weed control in wheat, barley, triticale and rye, the following compatibilities are indicated. This product may be mixed with the following products without a significant loss of activity: Bromoxynil, Lontrel1 (up to 150mL/ ha), dimethoate, omethoate and phosmet. This product may be mixed with the following products, but some loss of grass weed control and/or speed of kill should be expected: Bromoxynil + MCPA, Tigrex1 (max. 800 mL/ha), MCPA LVE (max. 700 mL/ha). 

    This product may be mixed with the following products, but some loss of wild oat control should be expected: Jaguar1 (up to 750 mL/ha), Eclipse1 (up to 7 g/ha).
  2. When mixing with broadleaf herbicides and a non-ionic surfactant (1000g/L) at the rate of 250 mL per 100L of spray solution. Reductions in grass weed control (as indicated above) can be minimised by using a minimum of 80 L of water per has by ground and 30 L by air, and if wild oats are present, use 2.0 L Diclofop Methyl Herbicide/ha (except barley). Do not use Bromoxynil + MCPA at rates above 1.4 L/ha when mixing with Diclofop Methyl Herbicide.
  3. Allow at least 10 days between any application of Diclofop Methyl Herbicide and other herbicides containing 2, 4-D, MCPA, dicamba or other similar sprays, which should preferably follow Diclofop Methyl Herbicide.
  4. For use in oilseed poppies in Tasmania only: Diclofop Methyl Herbicide may be mixed with pesticides as recommended by the Department of Agriculture or the poppy contracting company.
  5. Where phalaris is present, Diclofop Methyl Herbicide and Puma1 S may be applied together at the respective recommended rates. Wetting agent should be added to this mixture at the rate recommended on the Diclofop Methyl Herbicide label.


Ground Sprayers - Standard boom sprays only are recommended and must be fitted with by-pass-pass or mechanical agitation. It is recommended to use approximately 50 to 150 L water/ha and a droplet size of 200 to 300 microns. Do not apply with boomless jets or misters.


Aircraft - Best results have been obtained using 20 to 30 L water/ha with a steady cross wind and a swath width of 15 to 18 metres. Aim for a droplet size of 200 to 300 microns. Do not exaggerate swath width. Aircraft operators should consult manufacturer for details.




Do NOT apply if rainfall is expected within 2 hours.

Do NOT spray when temperatures are higher than 25 C.

Do NOT apply to weeds or crop under stress due to, for e.g., very dry, very wet, nutrient deficient, frost or diseased conditions.


Resistance Warning


Diclofop Methyl Herbicide is a member of the aryloxphenoxypropionate group of herbicides. Diclofop Methyl Herbicide is an inhibitor of acetyl coA carboxylase. For weed resistance Diclofop Methyl Herbicide is a Group A herbicide.


Some naturally-occurring weed biotypes resistant to Diclofop Methyl Herbicide and other Group A 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 Diclofop Methyl Herbicide or other Group A herbicides.


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


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, adjacent crops (eg. maize, sorghum, rice) crop lands or pasture.


DO NOT plant susceptible crops (eg. maize, sorghum, rice) for 10 weeks after application.



Diclofop Methyl Herbicide does not affect undersown clovers or medics or other broadleaf crops, and has no activity against broadleaf weeds.


Safety Directions


The product may irritate the eyes and skin. Avoid contact with eyes and skin and do not inhale spray mist. When preparing spray, wear cotton overalls buttoned to the neck and wrist, and washable hat and elbow-length PVC gloves and face shield. 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 and contaminated clothing.



Store in the closed, original container in a cool, well ventilated area. DO NOT store for prolonged periods in direct sunlight.



Triple or preferably pressure rinse containers before disposal. Add rinsings to 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 500mm 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.
