Practical recommendations
Dealing with weeds
Conservation tillage must exclusively be kept to
1
clean 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 cient-
ly get rid of graminae; on the other hand, cereal crops
allow effi cient action to be taken against dicotyledo-
nous plants.
Sow stale seed beds during catch-crop periods to
3
get 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
4
stale seed bed's effi ciency.
The longer the catch-crop period, the more effi cient
weeding 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
6
the 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).
Monitor the growth of plant life in the crop during
7
the 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 improving 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 observations down and trace
the history of each plot of land.
Use herbicides of new chemical categories every
8
year.
Clean borders, fallows and crops before the
9
heading.
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 preferable 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 lo-
calised 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
dicotyledones.
