mph. Exceptions are of course liquid fertiliser and
herbicides whose selectivity is based large droplets that
will only stick to the weeds
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 chemi-
cal label regarding drop size, spray pressure, spray
volume rate etc. this should be followed. Enclose 1 bag
of water sensitive paper and instruction of how to use
with all TWIN sprayers.

NOTE! All volume rates, pressures and air suggestions indicated in these tables are only guiding. Special conditions regarding climate, quality
of the crop, spraying time and chemicals applied (burning) may partially change the procedure.
* NOTE! If dust is deposited on leaves the air speed must be reduced.

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 (droplets) on the paper. This
way you can test different spraying techniques. Water
sensitive paper is available at your local HARDI dealer,
part No. 893211
