With the HERBI-4 herbicides are usually applied in around 20 litres total spray

10 litres per hectare. These are lower volumes than recommended for high volume
application with knapsack sprayers.

Do not use herbicide concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
) a) specifically prohibits use of 'Reduced Volumes'i.e. increased concentrations;
b) has a statutory
diluted product at high volumes (N.B. this will appear in the statutory box on the
label);
or
c) carries one of the following hazard ratings: 'very toxic', 'toxic' or 'corrosive' or
carries the warning 'risk of serious damage to the eyes' e.g. paraquat (Gramoxone)
which is classified as toxic should not therefore be used through the HERBI-4 at
concentrations greater than recommended on the label. Micron do not generally
recommend using spray mixes of more than ten times the maximum concentration
recommended for high volume application with knapsack sprayers. The safest
product and lowest dose rate appropriate for the treatment should be used at all
times.
To prepare the spray mix first read the product label to determine the quantity of
product to be applied per hectare e.g. 2 litres of glyphosate per hectare. Then determine
the total spray volume to be applied per hectare with the Herbi-4 i.e. 10 or 20 litres per
hectare. Calculate the ratio of product in water e.g. 2 litres glyphosate + 8 litres water =
10 litre mix = 1: 4. Use this ratio to prepare the correct dose for the spray tank or bottle
e.g. with a 5 litre backpack mix 1 litre glyphosate with 4 litre of water.
