Wonderful Product

Have been on the hunt for a weed killer that didn't have glyphosate in it and was effective. Well, the hunt is over. Lonarch is fast and effective. The very next day everything is turning brown, even the broad leaf weeds. Bought the small size to give it a whirl. Next time I will purchase the larger container. So, so happy.

WOW!
By Paul on 02/14/2025
Used a hose end sprayer for short beds of weeds. 24 hours later ALL the green was turning to brown. We have 2 new dogs and didn't want to use the RoundUp type products. The sprayer laid down too much product but next year I'll know to move faster. All previous vegetation killers were more dangerous, costlier, and didn't work as well. We are in Central California and I sprayed in February with temps in the 50's.

Since Lonarch Herbicide does not migrate through the soil and does not translocate in plants, areas may be replanted 24 hours after spraying Lonarch Herbicide Weed Killer Concentrate as directed oer the manufacturer.

My backyard has weeds that need to be addressed and controlled. However, I allow my dog to use the yard in the back daily. I'm reluctant to use anything at the moment. Can I apply this product by spraying the entire lawn? And will it be safe for my dog after the application?
Lonarch Herbicide Weed Killer Concentrate is an eco-friendly non-selective herbicide which means it would also kill the centipede grass. IF you just want to kill everything including the grass and reseed/sod the area you could use it.
As long as you keep pets/children out of the area while you treat and until the product has had time to completely dry or settle there is a reduced risk for children and pets. Typically after 4-6 hours.Was this answer helpful to you? YesNo

I’m looking for a weed control in my lawn that will kill the weeds and not my lawn
Lonarch Herbicide Weed Killer Concentrate is not labeled for residential lawns, but it is targeted to kill grasses as it is a non selective herbicide. In order to be able to recommend a product safe for your lawn, we would need to know what type of lawn you have & what weeds you are targetting. We would also need to know many square feet you are treating. If you do not know either or both, you may get them identified through your extension office or a local lawn care company as DMO no longer offers weed identifications
