Warm Season Weed ID Thread - What is it and how do I kill it?
Looks like Doveweed. I think a couple doses of Celsius is supposed to take it out.Jason229 said:
@stormchaser I'm dealing with the same weed/grass (also in Miami with St. Augustine). Posted the question on this thread not too long ago and haven't received any feedback. I've been searching online for ever and I can't pin point what it isstormchaser said:I'm new to the forum and live in Miami with St. Augustine (mix of Palmetto and Seville). I use Celsius WG post-emerg and Prodiamine 65WDG for pre-emerg. This combo takes care of all my weeds except for the one pictured here, which I am having a heck of a time with. Could someone help me identify it and how to get rid of it (without getting rid of my grass!)

It already took over a considerable part of my lawn.
I had a question about adding NIS and MSO to my Celsius. When you say 0.25% vol per volume. Does that mean if I make a solution of 1 gal of solution containing Celsius, I need to add 0.32 fl oz of NIS or MSO??Ware said:I agree. Celsius WG herbicide is a postemergent herbicide with (3) active ingredients to provide control of most broadleaf and grassy weeds we encounter. A list of weeds controlled can be found on pp. 4-5 of the label linked above. Celsius is one of the few herbicides that are safe for use on warm season grasses like bermuda when temperatures are high.dfw_pilot said:First, start with a purchase of Celsius herbicide.
At ~$100 for a 10oz bottle, it seems expensive, but a bottle will actually treat over 88,000 sq ft at the high rate. If you are maintaining proper pre-emergent control and using Celsius in a spot-spraying capacity, a bottle will likely last you many years.
A non-ionic surfactant (NIS) or methylated seed oil (MSO) may be used at 0.25% volume per volume (v/v) to improve effectiveness when temperatures are below 90F.
As always, read and understand the label before using this product.
