Did a few apps of 1-2-3 NPP - refreshing smell!

    Got out and did my first round of fungicide apps today for lawns infected with NRS. Mixed up a few backpack fulls of 1-2-3 NPP with LI-700 to acidify my water supply. Smelled like I was spraying clove scented weak orange juice on the lawns:) It was actually a little refreshing, rather than the usual 2-4D ester stink I usually suck in.

    Will be good if I avoid an outbreak of NRS in these lawns which typically happens late June through mid-July. This product better work:)

    NPP is a good product, but it takes more than spraying it to keep diseases at bay. Like I mentioned in another thread, don't apply high N fert in the summer. I would switch over to a more organic based fert that encourages soil microbial activity rather than a quick N release (if you don't do so already). IMO, a more holistic approach may be the better solution rather than applying a fungicide.

    Didn't think you could spray from a back pack. Not enough water? Barry are you able to spray from a backpack?

    Question not meant for me, but I use to use a Stihl SR420 (mister) with this material. I mixed on the fly as the NPP will sink to the bottom of the tank.

    With this material, water isn't an issue as this material is mostly meant for disease suppression, but the stuff I had didn't have curative and preventative rates. I know Bill used to say you could use it for grub control as well, then you would definitely need more water.

    You can spray NPP with a back pack for fungal diseases.

    Ya the NPP directions state to mix 2-3 ozs (depending on if preventative or curative) of product with one gallon water to cover 1k sq ft. Backpacking is suited well for this (for smaller lawns).

    It smells good but I don't think it works. I tried it on a small section under a tree that had powdery mildew (I think because ther was excess nitrogen from some miraclegro soil added that was lefetover). Didn't do a thing.

    I have a few sections that had some smut disease, did not do a thing. I ended up using a more traditional fungicide which worked fine. I'm not trying to put the stuff down but so far it does smell good but has been worthless imo.
