General Instructions

NOTE: For cereals, the flag-2 leaf is the 3rd last fully emerged leaf i.e. the second leaf below flag.


Shake well before use. Fill the spray tank and then add concentrate. Mix well. BUMPER may be applied by ground rig, high or low volume, or by air.

Pineapples - Pre-plant dip:

Add the required amount of Bumper directly to the dip and mix well. Avoid excessive contamination of the dip with organic matter.


May be applied by boom spray or aircraft. Ensure complete coverage of all leaves and stems is obtained. The object of spraying is to keep the upper 2-3 leaves green and functioning through grain filling stage.

With aircraft, as a guide, apply 10-20L/ha with the lower volume being used when applications are made with a cross wind of not less than 5 knots. Use the higher volume when applying to dense crops.

Tree and Vine Crops:

Apply by high volume dilute sprayer only.

Dilute Spraying:

Use a sprayer designed to apply high volumes of water up to 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. Apply sufficient water to cover the crop to the point of 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 100L of water.

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


BUMPER may be mixed with any one of the registered products containing azinphos-methyl, chlorothalonil, copper oxychloride, demeton-s-methyl, diazinon, dimethoate, mancozeb, metalaxyl, methomyl, parathion, propargite and zineb.

Precautions Re-entry
