Liquid Copper Fungicide is a Bonide patented, natural copper formulation that protects everything from turf, to veggies, to fruits and flowers. This is approved for organic gardening and controls powdery mildew, black spot, and rust!
Controls powdery mildew, downy mildew, black spot and rust.
Controls peach leaf curl.
Shake well before use. Most conventional liquid pesticide plant sprayers can be used to apply this to plants. Mix 0.5 to 2.0 fluid ounces of this in a gallon of water. Unless otherwise stated in specific application notes, apply 1.1 to 2.3 gallons of diluted spray per 1,000 sq. ft.
For best control, start spraying before the disease is visible or when disease is first visible on the plant. Spray all plant parts thoroughly (top and bottom of leaves), and unless otherwise directed in the crop table, repeat every 7 to 10 days. Use the higher rate to control diseases that may go dormant and overwinter. See application notes for the specific crop application interval. If possible, time applications so that at least 12 hours of dry weather follows application. Reapply after rain, following crop specific application interval.
Hydroponic use: Apply as soon as disease appears, or as a preventive spray 2 weeks before disease normally appears. Apply as a foliar spray only. Do not apply directly to the water in hydroponic gardening systems. Discarded water from hydroponic growing systems may be used in greenhouses and to water indoor and outdoor container plants and garden areas. Water from these systems is prohibited from being discarded directly into a water source.
When powdery mildew presence is expected on a plant, spray the plants at the minimum application interval during the first 2 weeks after emergence. To control downy mildews, leaf and fruit spots, blights, and rust, begin treatment 2 weeks before disease normally appears or when weather forecasts predict a long period of wet weather. Alternatively, begin treatment when disease first appears, and repeat as long as needed.
To prevent fruit rots, apply at the start of flowering and unless otherwise directed in the crop table, repeat every 7 to 10 days until harvest. Fungicidal sprays are especially warranted when weather forecasts predict a long period of wet weather.
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.
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.
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!
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.
