    5 of 5 Stars  Checked Tomato Blight!
    By Bill on August 10, 2011
    Verified Purchase

    After researching treatments for early and late blight, I found great data on the Cornell University's Ag department web page. They recommended using a copper based fungicide for control of both early and late blight. Bonide Liquid Copper Fungicide was purchased and applied to five varieties of tomatoes (30 plants total) planted in my home garden. Some had advanced early blight. I had applied other "safe" fungicides prior to using Bonide Liquid Copper Fungicide with very poor results. Following the manufacturers directions I applied the maximum recommended rate due to the advanced stage of the blight on some of the tomato plants. All 30 plants received 2oz. per gallon of water. The results are nothing less than spectacular! The blight is now under control and my harvest to date (8/10/11) has been way above average with more to come. I also applied Bonide Liquid Copper Fungicide to my eggplants that also had blight problems with good results. I plan to use this product on an every 14 days application schedule or after heavy rain. I strongly recommend Bonide Liquid Copper Fungicide for home gardeners who are having a variety of blight issues with their veggie gardens.

    5 of 5 Stars  Cotrolling Early Blight
    By Rebecca on July 23, 2011
    Verified Purchase

    I tried 2 applications of Daconil 2787 for blight control on Tomato Plants with no improvement. Since I have applied Bonide Liquid Copper Fungicide twice at 1 week intervals, I have not noticed any new areas of blight on my Tomato Plant leaves. The plants are looking very healthy now.

    5 of 5 Stars  Working!
    By Judy on September 18, 2011

    Sprayed my tomato plants once for blight. Seems to have halted disease, plan to spray again after coming rainy days. I should have had this at the beginning of the planting season so I could spay before disease took hold!

    5 of 5 Stars  I think it works....
    By Larissa on June 5, 2014
    Verified Purchase

    Over the last two years I got a horrible fungus problem: last year I lost all my tomatoes to it and this year I can already see it spread onto cherry trees. It started a few years ago on pear and apple trees. I did not want to use anything harsh, and my dad kept telling me that in his youth they used copper based fungicide. I was so happy to find it here (FINALLY). I spray everything in my garden 2 times and I can see that fungus damaged leaves on my trees and shrubs are dried up and falling off. I am happy to see that! I don't know yet how often do I need to repeat the application so the fungus does not come back. We will see. But I am happy to see that my red currant and honeyberries started shooting new leaves. Last two years they were barely surviving in the summer.

March 27, 2011 Debi asked:

QHow long does liquid copper fungicide take to kill turf algae and when can I then spread new grass seed over?

AHow long liquid copper fungicide takes to kill turf algae will depend on how far the turf algae has progressed and how spread out it is.  You should apply this product as soon as the algae is noticed and repeat application every 7 to 10 days until the algae is gone and controlled.  Typically after applying any herbicide product, you should wait 6 to 8 weeks until reseeding.  Please read the product label for specific mixing and treating instructions for treating turf.
