    We have those with another name..."Common Vetch". It's easily knocked out with Atrazine (.75oz) and Basagran (.40oz) mix. However, wait for a cool series of days (85 or below) You could burn your centipede. Of course, it will probably die just because you try to help it anyway.

    Whave that here as well. I didn't know the name of it but have been spraying it with metsulfuron. Hard to get it all. It's not Vetch though. It has a woody stem and grows much tighter and lower to the ground than vetch.

    Chamver bitter use manor. It will control it without yellowing grass- if you mix it correctly.

    It is definitely chamberbitter, or gripeweed. We have alot of it here in B'ham. Atrazine works the best on it but corsair will do the job in warmer temps. If you have centipede turning red it is probably not red thread but just the time of year. Centipede will also develop red leaf tips when it has an iron deficiency so you may want to try some Ferromec to see if that improves the color.
