General Instructions


MANCOZEB 750 WG Fungicide is a protectant fungicide for the control of certain fungus diseases in many crops.


For best results, apply as a regular spray programme.


Thorough coverage of the treated crop is essential.


Fungicide Resistance Warning


For fungicide resistance management MANCOZEB 750WG is a Group Y fungicide.


Some naturally occurring individual fungi resistant to MANCOZEB 750WG and other Group Y fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by MANCOZEB 750WG and other Group Y fungicides, thus resulting in a reduction in efficacy and possible yield loss.


Since the occurrence of resistant fungi is difficult to detect prior to use, FMC accepts no liability for any losses that may result from the failure of MANCOZEB 750WG to control resistant fungi.




Slowly place into spray tank as it is being filled, or thoroughly premix in a nurse tank for concentrate or aircraft sprayers. Add other co-applied fungicides, insecticides, surfactants etc after MANCOZEB 750 WG Fungicide has been placed into suspension.


Maintain sufficient agitation during mixing and spraying to prevent the product settling out and to ensure a uniform spray mixture. Rinse out spray tank, pumps and nozzles at the end of the day.


When preparing spray solutions for use in hand sprayer, premix as a slurry in a small container, and then add to sprayer containing one-third to half desired final water volume.



The addition of agricultural surfactants to MANCOZEB 750WG Fungicide will improve initial spray deposits, fungicide redistribution and weatherability.


Use a Spreader-Sticker per label directions if needed.





Use a sprayer designed to apply high volumes of water up to the point of run-off and match to the crop being sprayed.


Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of fi rst run-off. Avoid excessive run-off.


The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from Industry guidelines or expert advice.


Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of run-off.


The required dilute spray volume will change and the sprayer set up and operation may also need to be changed, as the crop grows.



Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed. Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.


Determine an appropriate dilute spray volume (see Dilute Spraying above) for the crop canopy. Consult your local advisor, agronomist or Department of Agriculture to determine this volume. This is needed to calculate the concentrate-mixing rate.

The mixing rate for concentrate spraying can then be calculated in the following way.


Concentrate Spraying Example

1. Dilute spray volume as determined above: e.g. 1,000 L/ha;


2. Your chosen concentrate spray volume: e.g. 500 L/ha;


3. The concentration factor is 2 x (1,000 / 500), and; 4. If the dilute label rate is 150 g/100 L, then the concentrate rate becomes 2 x 150, i.e. 300 g/100 L of concentrate spray.


The chosen spray volume, amount of product per 100 L of water and the sprayer set up and operation may need to be changed as the crop grows.


For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow Industry Best Practices.


For concentrate application, use a spray volume of 20 L or more per hectare.


For dilute application, apply to run-off. See Dilute Spraying above.



May be applied by agricultural aircraft.


Use at least 30 to 50 litres of spray mixture per hectare. Consult the Directions For Use for the correct rate to be applied in specific crop situations.


Spray Timing

Treatments should begin prior to disease infection and continue until the threat of disease has passed.


Repeated applications are necessary to protect new plant growth.


Reduce the spray interval when weather conditions favour disease development.



MANCOZEB 750WG Fungicide may be harmful to Typhlodromus pyri, and its use in orchards where integrated control is practiced should be avoided.


This product is compatible with most commonly used agricultural fungicides and insecticides, however, before preparing tank mixes, the user is advised to check compatibility with the other manufacturer's recommendations.


Protection of wildlife, fish, crustaceans and environment

This product is toxic to fish.


Drift and run-off from treated areas may be hazardous to aquatic organisms in neighbouring areas.


DO NOT contaminate ponds, waterways or drains with the chemical or used containers.


DO NOT re-use container.


Safety Directions


May irritate the eyes, nose, throat and skin.


Avoid contact with eyes and skin.


Wash hands after use.



Store in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight. Keep away from fire and sparks.


DO NOT allow to become wet or overheated in storage: decomposition, impaired activity or fire may result.


DO NOT store near food, feedstuffs, fertilizers or seed. Users are reminded this product should be used before the stated expiry date.



Shake empty bag into spray tank. Do not dispose of undiluted chemicals on site.


Puncture or shred and bury empty containers in a local authority landfi l. 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 bags and product should not be burnt.
