Trimec
1 of 5 stars
By Charlie in Bossier City on 06/12/2023

I applied this product as directed, expecting to see quick results. Not only did it not work, the weeds were just as healthy. I wasted my money. I'll be more attentive to who I talk to at DMO.

Expert Response  Expert response:

Please keep in mind that It can take 14 to 21 days to see results on young, actively growing weeds when using a product like Trimec Southern. Depending on how well established the target weeds are, it could take a full 21 days, and a repeat treatment may possibly be needed. Additionally, this product is only labeled for use on broadleaf weeds, but will not be effective for targeting grassy weeds.

Kind of works ok. Not all weeds go away. Spurge is still prevalent. Will have to check again in spring summer time when grass is greener or weeds pop again.
