oak trees infested with white flies

 

I have 16 50 foot plus Oak Trees infested with White Flies. What will be the best product to use and system to kill them? Bifen, Nylar, Merit?? Ground, Injection, spray?? It is really bad they are all over. Location is Pompano Beach Florida. Thanks.

Once tall trees like an oak get infested with white flies, it’s best to go with a “one – two” punch of products to knock them out for good.

The first “punch” is to spray as much of the tree as you can with nothing but BIFEN. Forget the SPREADER STICKER since it’s the middle of the summer and the temps are so warm. In warm conditions, the Spreader Sticker can do more harm than good so only use it from November to March in your region. And even without the Spreader Sticker added to the tank mix, you’ll get fine results with nothing but Bifen.

Right after the Bifen is applied, ground drench any tree you want to protect with MERIT WP. This treatment will take a good 1-2 months to kick in and show results but once it gets distributed throughout the tree, you’ll see a huge improvement and won’t have to spray anymore. And starting next year, if you apply Merit to any tree you want to protect every February, you won’t have the problem return that year.
