Napropamide is a selective systemic amide herbicide.

The compound is used against a number of annual grasses and broad-leaved weeds.

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 they germinate.

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 contact herbicides.

While better control will be achieved with thorough coverage, systemic herbicides can move through plant tissues and may work on smaller

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, such as

broadleaf weeds, while a non-selective herbicide is active on most plants, such as broadleaves, grasses, or sedges.
