Yara N-Sensor V3.10 Operation Manual
5.4 Potato haulm killing
This operation mode provides algorithms for site specific dosing of potato haulm killing
herbicides. The Potato haulm killing module (MLHD PHK module) can be used to apply
Reglone® (diquat dibromide 200 G/L), Finale® 14 SL (glufosinate ammonium (150
G/L) and Spotlight Plus (carfentrazone-ethyl 60 G/L) in a site specific manner. The
module also contains dosing algorithms for two other products (Purivel® and Spot-
light® 24 EC), but their use is phased out in most EU countries today.
In the next two sections, agronomic calibration and operation of the potato haulm killing
herbicide is explained. More detailed background information and tips & tricks on
MLHD PHK are given in the subsequent sections
5.4.3 and 5.4.4.
5.4.1 Agronomic calibration
To enter the agronomic calibration menu, press the Agronomic. calibration button on the
main menu bar of the Potato haulm killing work screen (see section
2.3 for general ex-
planation of this work screen). Usually, this menu is entered at the beginning of the
field after a task has been selected.
The agronomic calibration menu itself consists of three pages that can be navigated
using the Up and Down buttons.
Agent: Select the agent type to be applied by successively pressing the Agent button
until the desired agent is displayed.
Risk level: Select the risk level (Normal or High) by successively pressing the Risk level
button until the desired risk level is displayed. High risk situations are situations
when there are many weeds or there is Phytophthora infestans in the crop, or
when the crop plants have very long stems and a lot of them are laying compacted
on the soil (lodging of the canopy). In these situations, a higher dose can be ap-
plied by selecting a high risk level to set a dosing algorithm which doses a little
higher then the one to be used for normal risk or standard situations (see also + 10
% button options on next page)
