Weed
control
The
onion is very weak against weeds, since the upright tubular leaves
of this single-cotyledonous plant cover the ground only slowly and
incompletely. Although today there are some efficient herbicides
for onion cultivation, the following rule is still valid: The weed
control takes place in the preceeding plant and not in the onion
population itself. For the application in the preliminary stage,
before the plants begin to sprout, the herbicide Stompsc has been
authorized. Preconditions for the use of Stompsc are a minimum depth
of 2 cm and a crumbly soil. Depending on the extent of the weeds
and the soil type, 4 -6 lt. Stompsc are applied onto the slightly
humid soil in the evening hours or when the sky is clouded some
time before the plants begin to sprout.
Note:
Stompsc is only efficient against germinating plants, not against
those which begin to sprout already! (in this case a total herbicide
is required) There are various herbicides for the weed control before
and after the germination phase on the market. As the guidelines
for their use are constantly changed, please ask for expert advise.
