We have a Christmas Tree farm in north Florida. Two of the seven species that we grow are favorites of the saw fly. Two years ago we began using CoreTect and found that not only did it control the saw fly in our young seedlings but also helped control pine tip moth as well in the Virginia pines. We also noticed that the seedlings treated with CoreTect were more vigorous in their first year of field growth.
We have 5 Hack Berry trees in our backyard. Due to a lot of rain, which spurred new leaf growth,the trees contracted an infestation of Wooly aphids. We bought the Coretect product and also a deep root feeder. My husband injected the root feeder a couple of feet into the soil and and fed the trees, irrigating the product into the root system. After about a week we also had 1.5" of rainfall that helped get the product to the roots. The aphids are gone and we have our backyard back!
I have purchased the Coretect Insecticide twice from Do MY Own, they have shipped promptly and made it an enjoyable process. The CoreTect product is by far the quickest and easiest way to treat our hemlocks.
