Micron Herbi4 Instruction Manual page 7

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
concentrations;
b) has a statutory requirement for use of personal protective equipment when
using the 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.
