Try Remedy and Reclaim mixed with water and dish soap. I got the same kill as with Remedy and diesel, it was cheaper and and a plus not using high dollar diesel. I use a 25 gallon sprayer in the back of my Mule. Been doing this for many years and it works great.

Thanks for the suggestion, but do you mean "Remedy OR Reclaim"? Surely not both?

Yes, mix both together. I believe it's 2oz of each per gallon of water but I'll have to check. I use that and picloram for cactus and Roundup for weeds so I don't remember off the top of my head the different mix ratios for each. They sorta run together. I'll check the next time I go into my shop. Also about 8oz of dish soap for 25 gallons.

I use this mix at a rate of 0.8 oz of each/gal water or equates to ~2.5 oz, of each/3 gal. water and I used "Induce" surfactant. This worked good foliar applicated to small mesquite. I use the remedy/diesel sprayed on the bases/trunks of bigger mesquite.

Here is a tip:

add a few drops blue food coloring to the tank if you spray with a hand wand, this way you don't spray the same bushes/trees over and over

Sendero is newer chemical from Dow for leaf spraying. Takes the place of the reclaim/remedy mix, as it requires no chemical mixing and is supposed to have a higher kill rate. Mixes with water. Around $170/gallon but makes around 100 gallons of spray. Recommend use of seed oil or surfactant to help stick to leaves. Can only be sprayed at correct times of year (late spring early summer). Dye also helps.

Remedy and diesel for basal spraying can be done year round. Backpack is the way to go. I use less Remedy than recommended and still get great results.

Sendero is not technically the same as a mix of Reclaim and Remedy. Sendero is a mix of Aminopyralid 23.4% and Clopyralid (Reclaim) 5.8%. Remedy is Triclopyr, not Aminopyralid. Dow/Corteva claims 17% better kill rates after 2 years with Sendero vs R&R. There is no doubt mixing Reclaim and Remedy as you do will be successful, as that was the "go to" Brushbusters standard for years, but that mixture is not the same as Sendero.

Aminopyralid (Milestone) is $355/gallon. This price difference of $355 for Aminopyralid and $75 for Remedy/Triclopyr would also show that they are not the same chemical.

To your point about cost difference: 2 gallons of Sendero will cost around $340. 1 gallon of Remedy and one gallon of Reclaim (Sonara) will cost around $230. Both methods yield 200 gallons of spray. So, arguably $110 more or so per 200 gallons for an alleged 17% better kill. 17% of mesquites sprayed with 200 gallons of spray does not seem inconsequential.

Sendero works mainly on mesquite and locust. R&R will kill more plant species, which could be an advantage.
