Practical recommendations
Dealing with weeds ?
Conservation tillage must exclusively be kept to clean
1
fi elds.
Perennial weeds, in particular, must be kept under control
during the previous seasons.
Weeds must be dealt with within the framework of
2
crop rotation.
Alternate cereal and dicotyledonous plant crops (peas,
rape, beetroot etc.) as well as winter and spring crops.
Dicotyledonous crops give an opportunity to effi ciently
get rid of graminae; on the other hand, cereal crops allow
effi cient action to be taken against dicotyledonous plants.
Sow stale seed beds during catch-crop periods to get
3
rid of yearly weeds and regrowths.
As soon as the combine harvester has harvested the crop,
a homogeneous, superfi cial and rolled «bed» of seeds
must be prepared, using fi ne soil, so that the weed seeds
emerge as regularly and completely as possible. One week
before sowing, destroy the emerged plants by means of
mechanical tillage or total non carry-over herbicide, such
as glyphosate or sulfosate. Aim to have no weeds at all at
the time of sowing.
Avoid sowing too early in order to improve the stale
4
seed bed's effi ciency.
The longer the catch-crop period, the more effi cient weed-
ing will be. Sow trashy fi elds last. Trust the quick effi ciency
and the emergence quality of the Easydrill to enable you
to sow at the usual dates, without any risks.
As soon as the sowing is fi nished, keep clean and
5
strong crops growing.
Use clean seeds that are free of weeds and have good
viability. The seeds must be placed to obtain a fast and
grouped growth, to create a crop that will be able to
compete with weeds.
Use a seed drill that causes little disturbance of the
6
soil, such as the Easydrill.
The Easydrill works exclusively in the sowing line, which
avoids seeds that escaped the stale seed bed emerging.
Prefer wide spacing between rows, such as that of the
Easydrill (16.6 cm). Use the seed drill's rear harrow only
when necessary.
Monitor the growth of plant life in the crop during the
7
growing period.
With conservation tillage, the usual weeds do not appear
in the same quantities or at the same dates; additionally,
new species may appear. Prepare for this evolution by im-
proving your botanical knowledge. Every week while the
crops are growing, walk through the fi elds, moving into
plots of land in a continuous series of «Ws», identifying
plants and their respective development; write any obser-
vations down and trace the history of each plot of land.
Use herbicides of new chemical categories every year.
8
Clean borders, fallows and crops before the heading.
9
Cut or shred weeds on embankments, in ditches and in
fallows rather than treating them with total herbicide:
some perennial plants might not react to the product, and
may then become diffi cult to get rid of. Some fi nd it pref-
erable to grow rye-grass on borders: it chokes weeds and
can easily be kept under control using a mower. During
the season, destroy the remaining localised weed growth
spots using localised treatments, your usual sprayer, or by
hand.
Avoid scattering weed seeds when harvesting.
10
Start harvesting the cleanest plots of land. In weed
infested plots, harvest the cleanest parts fi rst. Clean the
combine harvester well after harvesting weed-infested
land.
Ploughing is a last resort if the techniques above are not
effi cient enough to get rid of annual grass or dicotyle-
dones.
