Compare-N-Save Systemic Tree and Shrub Insect Drench - 75333, 1 Gallon

The ash tree in my front yard has been infested with aphids the past couple years and it was time to take action. The little beasties don't kill the tree but I was getting tired of the ugly aphid clusters and being "misted" while walking or mowing beneath them. I read a lot of reviews of different treatments and this one seemed very promising. After a bit of research I decided to take a 2-step approach of using this product and also spraying the leaves with a water-and-dish-soap mix. Earlier this spring the tree already had leaf damage and aphid clusters. Within a week of using this product I could already see improvements. Six weeks after the treatment the improvement is amazing. There's no sign of aphids, the tree's leaves are dark and shiny, and there's even new growth. The product instructions are clear, and it's easy to use. Basically you calculate the number of ounces to mix with water (based on the tree trunk size) and pour the mix around the base of the tree. The jug is also packaged well, as it comes sealed in a bag within the box so you don't have to worry about leaks. It's a good value, too, since I'll get a couple more seasons of treatment out of it. 10/10 would buy again.

This systemic works great! My pittosporum hedge was attacked by mealy bugs so badly I didn’t know if they could be saved but it worked. A trim back this past spring and they look fresh again. Daughter used on several tall crepe myrtles and it worked on them also. I also used on my desert rose/adenium that had scale starting to attack. All plants healthy now. Will use in more diluted form as maintenance prevention.

HELPFUL INFO: I found the product info to be insufficient in the listing, as I had no direction on how much product I would need. The water:product ratio is simple, and could easily be in the listing, to help customers with an estimate of gallons needed! I highly recommend pre-measuring the tree trunk(s) to be treated, especially if you have several, and noting them in a similar fashion as I've pictured. Then do the math! The breakdown is easy: 1 ounce of product per 1 inch of the diameter of the tree trunk (at chest height). Or, 3 ounces per foot of shrub height. These amounts are added to 1 gallon (or 2) of water, and simply poured right around the base of the trunk. Needless to say, I'll need far more than 128 ounces (1 gallon) to treat the multiple trees in our yard. ** I'll update my review in a couple months, allowing enough time for aphid elimination, based on the absence of honeydew all over our deck and outdoor furniture. UPDATE: It's obviously been more than a couple months. The product does work. But I also learned that application is necessary in the early spring (April) so that the tree has sufficient time to take-in the product prior to the start of aphid activity. Otherwise the aphids get a head start, damage begins, and you're playing catch-up the rest of the season. Today is April 2nd, and I'll be retreating no later than the middle of the month.👍🏻

If you have Ash trees and are concerned that you might end up with Emerald Ash Borers (an invasive pest that kills Ash trees), an effective deterrent is Imidacloprid. I buy 2 gallons of this every spring. Rather than mixing it with water before I pour it, I pour it straight around the trunks of our trees and then I just use the garden hose to add several gallons of water. It's a cheap and easy way to protect your trees. I've mixed it with water and sprayed it onto my gardenia plants to kill white flies. It worked fantastically. I've sprayed the soil of houseplants to kill fungus gnats and it worked perfectly there too. If your tree trunk is about 2 feet in diameter, then use 1 gallon of this treatment. If your trees are smaller, you don't need as much and can save some for the following year. Each treatment is supposed to work for about 12 months.

I've been buying this for the past 7 years or so to protect my ash tree from emerald ash borers. My now 25-year old tree was definitely hit, I can see scars, but it is alive and doing pretty well while all of the non-treated ash trees in my town have died and been cut down. All of the untreated trees are gone. On my tree probably 95% of the canopy is alive. Anyway, this product is currently unavailable (I just came to buy another gallon for next year) but look for something with the same active ingredient, imidacloprid, 1.47%.

I had several trees infected with green/black and white fly. Nothing worked to kill or deter them and they were spreading. I bought this as a last resort, partly because of the price, but so glad I did. Within 2 weeks of treatment the horrors were dead and now I have new untouched leaves and buds 1 apple tree that was very infested had a second treatment and is now clear. I'll definitely treat every year now. We'll worth the money
