It pays off
to lower your weed seed bank

To increase the productivity of agricultural land and ensure excellent yields from high-quality crops, it is of crucial importance for farmers to reduce the weed seed bank. A persistent Integrated Weed Management approach will lower the weed seed bank, limit weed infestation in future, and put weeds off balance for better yields.

The overall objective is to stop weeds setting seeds and prevent the growth of the seed bank year after year. A reduced weed seed bank also means healthy and productive soil to hand over to the next generation. Ultimately, the equation is quite simple: fewer weeds mean bigger yields. Find out what multiple tactics and good weed control practices will maintain the value of your land.

Keeping a close eye on where and when weeds start developing in fields is a vital first step. Only hitting weeds hard and early can lower the weed seed bank and optimize the crop potential. It is crucial to employ not only chemical measures and to scout the field for survivors to avoid resistance development right from the start.

It is of high importance to know the weeds which can potentially damage the crop yield. Therefore it’s well worth increasing the weed know-how, e.g. by learning about the most problematic weeds.



Best weed management practices will sustain the effectiveness of current herbicides and enhance your farm’s productivity. Learn more about what best weed management practices mean here and real life experience on planning benefits here.



“Diversity is the future” is not just a neat slogan, it’s an insurance policy for your farm’s future. That’s because crop rotation disrupts the weed cycle and lowers the weed seed bank. Find out more here.



Using cover crops like alfalfa or clover increases the competitiveness of your yield-bringing crops – and that in turn lowers the weed seed bank. Find out how a carefully selected cover crop can significantly reduce black-grass infestation in heavy soil and greatly improve soil conditions to facilitate the establishment of spring crops here.

Tillage, cover crops, mixing herbicides, harvest weed seed control, crop rotation – the ideal strategy to lower your weed seed bank is in the diversity that must be applied through the weed control plan, combining cultural methods, and good agricultural practices. Find out how farmers worldwide are diversifying their tactics and listen to what experts have to say on Diversity in weed control here.

A clean field with no weeds or residues gives the crop a head start and is thus the best starting point to reduce competition by weeds and to achieve a low weed seed bank. A clean field may be achieved by mechanical or chemical measures or the combination of both (e.g stale seed bed). For more information about effective herbicidal modes of action click here.

One of the most effective ways of lowering the weed seed bank is through rotating herbicides across the crop rotation, i.e. applying herbicides with different effective modes of action to control the targeted weeds. For more details click here.
