Low drift nozzles can also be fitted on a TWIN sprayer and help reduce drift even further.
If there is a detailed spraying instruction on the chemical label regarding drop size, spray pressure, spray
volume rate etc. this should be followed. Enclose this one bag of water sensitive paper and instruction of
how to use with all TWIN sprayers.
It is most important that the sprayer operator is familiar with the above rules of thumb before using the
TWIN sprayer.
All volume rates, pressures and air adjustments stated in the following tables are, of course, guidance.
Special conditions regardings climate, crop quality, spraying time and applied chemical can change the
procedure. The tables are show practice in northern Europ, and conditions may be very different in the
other countries. If you want some local advice you are very welcome to contact the TWIN application
expert at the HARDI importer or daughter company in your country.
The volume rate can generally be reduced to half of what is applied with a conventional sprayer, but with a
minimum of 50-60 l/ha at 7-8 km/h. Exceptions are of course liquid fertiliser and herbicides whose selectivity
is based large droplets that will only stick to the weeds

USE WATER SENSITIVE PAPER TO HELP FIND THE BEST AIR SETTING. Some time spent in different types of
crops with clean water in the tank and some water sensitive paper will be valuable experience for the future
work with your TWIN sprayer. The paper can be cut into smaller pieces (to simulate the target) and fixed with
double sided tape at relevant places in the crop. Then spray with pure water and check the blue spots (dro-
plets) on the paper. This way you can test different spraying techniques. Water sensitive paper is available at
your local HARDI dealer, part No.893211
