BioAdvanced 701525A 12-Month Shrub Control Insect Killer and Tree Fertilizer, 1-Gallon, Landscape Formula Concentrate

I live in Oak Park IL, and since 2013 I have been treating a 100" circumference Ash tree infected with the Emerald Ash Borer. My only regret is that I waited too long to start, since the top of the tree was already dying. Nevertheless, the treatment did stop the progression of the infestation. Last fall I had the tree topped, and this spring all the old limbs as well as new growth shoots had large green leaves which have remained so throughout October. They are only now beginning to yellow which is the normal time of year for this to happen. The tree looks healthy now and over the past two years there have been no signs of additional damage. In contrast, the Ash trees in my neighbors yard (which were not treated) are almost dead. Unfortunately, there is the notion out there that nothing can be done but cut these majestic trees down...that it's too expensive to treat them. This notion also seems to be accepted by the Town and Villages who take advice from tree cutting companies that have a vested interest taking these trees down, not keeping them alive. If one looks at the overall cost, the estimate to cut down my Ash tree was $2,200. At $50/year for treatment, I can protect the tree for 44 years. So I'm really at a loss to understand why cutting these trees down is the best solution. In fact, treating these trees would seem to be the best solution for two important reasons: 1. it is cost effective; and 2. it actually results in stopping the spread of the local and national infestation. This is because treatment also kills the next generation of Emerald Ash Borers who have laid their eggs in the treated tree. So treating one tree also helps protect neighboring trees. In short, my advice would be if you have a large Ash tree and you want to keep it, begin treatment before it shows signs of infestation. That way you will preserve the tree's appearance, keep it healthy and don't have to come up with a big chunk of money several years down the line.UPDATE: It has been a year since I posted the above review and my Ash tree continues to remain healthy with a full canopy of deep green leaves and strong new growth. Only now are the leaves beginning to change to fall colors. The neighbors two Ash trees (which weren't treated) were cut down last spring which should decrease the EAB assault on my Ash. Remarkably, it is possible that I have the last Ash tree in Oak Park IL which is a sad situation. I will continue to treat this tree and report it's progress.

I had a company treating my ash tree for the past five years for aphids. Every year I was paying hundreds of dollars for multiple applications to the same tree with no complete resolution - the aphids were never totally exterminated and they were coming back every year. This year I finally decided to try something new - Bayer Advanced. I applied it as indicated in the directions on the bottle. In two weeks the aphids just disappeared! I couldn't believe my eyes - it worked so well that I'm still afraid they'll come back. It's true this product is not cheap, however, you need to apply it only once a year and the contents of one bottle will be enough for four applications, so four years (based on the size of my ash tree). This comes to be extremely cheap compared to the prices these companies charge for one treatment - $100/treatment which was bringing me to $300 a year only for aphids treatment. This product is also treating for Japanese beetles and Emerald Ash Borer, for which I was paying additional for separate treatments. This product is miraculous - I'm so happy I bought it! I highly recommend it to anybody who has all the above infestations to their trees.

Good product - no issues with Emerald Ash Borer since using - expensive - but cheaper than the professional service I was getting prior.

We've used this product for the past 5 years to prevent EAB infestation in our 12 ash trees. So far it has been effective. Plus, the trees have never been healthier - they have full canopies. By using this product for the do-it-yourself "drenching method" each spring we've saved hundreds of dollars & saved our trees. ( I used Extension videos to learn how to do it). The active ingredient is imidacloprid . You may be able to get cheaper versions, but I prefer this concentrate (2.94%) because I found the application to be easier (less mixing) & take a little less time. The only reason I didn't rate BioAdvanced (previously labeled Bayer Advanced) five stars is because of the packaging. The label for "Tree & Shrub Insect Control Landscape Formula" is very similar to their other products. Need to pay close attention to select the right one. The key is the active ingredient - imidacloprid. Typically, I've found this product only available on line.

I get lots of white flies and all sorts leaf nibblers and I don't like spraying bushes and trees AFTER they have an infestation. I feed this to all targeted trees and bushes in the yard about twice a year and it keeps the bugs away without me having to spray something on them that could affect animals or cause runoff into streams. It says 12 month but that's wishful thinking in the climate where I live. We get a lot of rain which dilutes it down after a while and it loses its effectiveness. 6 Months takes care of business so I don't have to deal with the bugs. Follow the directions carefully though. If you try to cheap out and not use as much as the directions tell you, it won't work at all.

Saved two mature ash trees from the emerald borer. Wish I would have known about this product sooner.

It works really well, but it's extremely expensive. I wasted a lot of money on this when I could've bought a pure or very high percentage imidacloprid. Don't be like me. Don't get this. Get the high concentration of imidacloprid meant for killing termites around a foundation. Just dilute it several times and mix it well before you put it on your trees.Also look at your laws. It might be illegal to use more than 0.5lbs of imidacloprid on your property. The raw stuff is very potent and wipes out many kinds of insects. I know bugs are nasty, but they're also necessary for nature.
