Anybody tried Celero 16 WSG systemic insecticide yet? I hadn’t heard about its interiorscape label since it first hit the market a year ago, until I saw an ad in a trade mag today.

It can be used as a spray or drench in interiorscapes, and it’s a different type of nicotinoid chemical than are Merit and Marathon. It’s labeled for aphids, whiteflies and mealybugs (and therefore possibly good on some types of scales, too?) and has a 12-hour REI.

Any firsthand experiences or info would be appreciated.

Hey Clem. Celero 16 WSP is in the subclass Thianicotinyl of the neonicotinoid class. Although it may be good for scales, as you mentioned it is labeled for aphids, whiteflies, and mealybugs. That is rather limiting, although there may be some supplemental information that I am not aware of. I have no first hand experience with this particular product, yet, as it is a neonicotinoid, I would say that for interiorscapers as a drench it is probably pretty good. If I recall, there were some solubility and translaminar differences between the subclasses, but that is often not very relavent to ’scapers as we don’t work with pesticides on the volume that other horticultural trades do. Therefore, I would not expect foliar applications to be the most effective route. Tell me this- how much is it and in what quantity? It may be inexpensive enough to try out. I’ve had cases where I’ve used hundreds of dollars of merit to suppress mealy (versus labor time spraying), and it was really worth the money for the efficacy. If you have a large scale application of this nature, I would definitely do some trial and error if you can afford to play. Often, there is no one to answer such questions as these but yourself. I loved "experimenting" when I was at FDS. Let me know what results you get if you decide to try it. Yours in benevolence, Lynnae Dehoff.
