Napropamide is a selective systemic amide herbicide.
The compound is used against a number of annual grasses and
Napropamide is applied to fields containing vegetables, fruit trees
and bushes, vines, strawberries, sunflowers, tobacco, olives, mint,
turf or other
crops. The compound is absorbed by the roots and works by
inhibiting root development and growth.
Napropamide also is a soil applied herbicide for pre-emergence
control of annual grasses and broad-leaved weeds in a range of
crops including oilseed rape, fruit and woody ornamentals. It acts
by preventing root cell elongation and so disrupting growth.
We can offer standards of the Napropamide. This will be of interest
to agrochemical companies and analytical labs.
Herbicides can be broadly classified as preemergence or
postemergence depending on time of application.
Preemergence herbicides are applied to the soil and kill weeds as
Postemergence herbicides are applied to weeds after they emerge.
Postemergence herbicides can be further classified as either
contact or systemic.
Contact herbicides are not translocated within the plant and only
affect the part of the plant that they contact, which means that
they will work on
aboveground tissues that are contacted by the spray.
Systemic herbicides are translocated within the plant and generally
are effective on plant roots.
Contact herbicides typically cause symptoms to appear much more
rapidly than systemic herbicides.
However, systemic herbicides offer advantages: Firstly, they are
generally more effective on perennial weeds that have extensive
root systems or
are spreading via rhizomes and/or stolons. Secondly, thorough
coverage is not as critical with systemic herbicides as with
While better control will be achieved with thorough coverage,
systemic herbicides can move through plant tissues and may work on
weeds even if the weed is not thoroughly contacted by spray. It is
also important to note that for these reasons, systemic herbicides
are much less
forgiving if ornamentals are inadvertently sprayed, and those
plants may not recover. Most woody ornamentals can eventually
recover if they are
accidentally sprayed with a contact herbicide.
Herbicides can further be classified as selective or non-selective.
Selective herbicides are only active on a particular type of weed,
broadleaf weeds, while a non-selective herbicide is active on most
plants, such as broadleaves, grasses, or sedges.
