Where do you get it? 
Why should you buy it?
NewsImage is a herbicide that should be used only if you have existing weeds coming up because you didn’t put down a pre-emergent at the right time according to our guide. Ideally, you want pre-emergent + a thick healthy Bermuda grass lawn to drown out any weeds and prevent them from growing. You should ideally never have to use a post-emergent herbicide.
The second approach is to follow our instructions for pre-emergents and fertilizer and just ignore your weeds till your grass recovers. You only have to keep mowing them down and disregard the fact that they grow taller and faster than your lawn for a short time.
24-D Amine is the best weed killer for all the popular Bermuda grass weeds we face in Texas at a fraction of the cost. 24-D Amine will work against all broadleaf weeds including crabgrass. It will not work against monocots (grass-like weeds) like Poa Annua (Annual Bluegrass) which is a grassy weed. You will need to use a pre-emergent to prevent Poa Annua (Annual Bluegrass) weeds or use this Image Herbicide if they are already growing and you need to kill them quickly.
Poa has seeds in the ground in the fall and winter and begins to germinate and form grassy weeds with white seed heads in spring. They will then spread seed all over your lawn and continue growing. 24-D Amine is in effective against it so Poa Annua will just continue to grow unhindered. It is a shallow root weed and likes to grow in low spots of your lawn where sprinkler water and rain water may pool. It robs surrounding grass of water. It usually will die off in the heat of the summer but will leave dead spots in your grass from where it was growing before. This is why you want to kill Poa Annua quickly if you didn’t put down a pre-emergent. Image will take 3-5 weeks for it to kill the Poa Annua. It is a very slow acting herbicide. It will yellow the Poa Annua until it eventually dies.
What’s in it?
The active ingredient in “3-Quinolinecarboxylic acid, 2-(4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl)-, monoammonium salt 3.3%” which will selectively kill many weeds including grassy weeds (monocots) like Poa Annua (Annual Bluegrass).

How do you use it?
Do not buy a surfactant to go with this as it will be a waste of money. It is true that many weeds are hydrophobic so liquids bead on them and don’t cling. You can just mix a little bit of Dawn dish soap into your sprayer after mixing your solution which will act just like a surfactant as you spray and breaks the water tension allowing the herbicide to stick to the blades of the weeds. You can use a pump sprayer or hose-end sprayer with it.
