    Agri-fos for pansy and snapdragon rot

    By Larry on 12/18/2012

    Verified Purchase

    We plant a lot of pansies and snapdragons in the fall. Stem rot and root rot can be a problem at times, especially in overly wet soils caused by long stretches of rainy weather or if the sprinklers are over watering. Treatment with this systemic product has given us 100% positive results in a test treatment of 20 flats of annuals planted in several different soils and locations. It worked as both a preventative and a curative in some flowers that had disease prior to treatment. This stuff looks like a keeper.

    It is really works

    By Maria on 06/27/2016

    I have a problem with ceder rust on my apple trees, bacterial leaf spot disease on my cherry and peach trees. My trees were severely affected! After first application all symptoms were stopped, but in two weeks symptoms have returned on remain foliage, so I had to make another application. In two more weeks all my trees showed up more new healthy growth and today, on the middle of summer, all my trees are absolutely healthy and, it seems, happy! I should use this product in early spring, and I'm definitely going to do it next year.

    I am giving this product the benefit of doubt since I can't prove its performance yet. It will take a couple of months though when it gets really hot in the summer in Mississipp. My italian cypress trees have a fungus and I read where this product and Cleary 3336f will heal it. I am still waiting to see the results.
