Nutgrass

Bioweed will suppress Nutgrass but it will take several treatments to control completely. This is because for every nut grass plant there can be multiple seeds or nuts under the plant. With follow up treatments you will be able to control the plant and the seed that the plant produces to stop germination in the future. It is important to get full coverage (to the point of run off) of the Nutgrass. Best results are seen when applied in the mid morning of a hot sunny day. 
Bioweed is non systematic so will struggle to kill the nuts. The process to kill the nuts is through starvation of the plant. This means it may take several applications to stop the growth then starve the storage system of the plant. 

Also known as Nut sedge.
