Fungicide for Flowers, Fruits and Vegetables

I am reviewing the Captain Jacks Copper Fungicide by Bonnie Products. This particular fungicide is for organic gardening and it can be used on flowers, fruits and vegetables. This is what caught my attention because I have been buying separate types of fungicide for each type of plants and this is an all in one! It controls a list of plant diseases such as black spot, powdery mildew, downy mildew and early blight with concentrations of copper. I found that the copper fungicide has worked the best so I first used this on my roses because they had black spot and it really worked on cleaning up the disease. I will reapply in about 7 days if they still show signs of the disease. Next summer I am going to be watching my grapes and if they show signs of powdery mildew I am going to try this spray on them. At the end of this years growing season I had an issue with the grapes and I wasn't aware there was a safe fungicide I could use on the fruit but now I have some that I am able to use. On the bottle they have attached a really helpful booklet that gives you directions as well as all the information on each type of plant, friut or vegetable you can use this on. I am very pleased with this product and I highly recommend it.

Plants love This

I recently started using BONIDE Liquid Copper Fungicide Ready-To-Use on my Rhododendrons and it's fantastic. I have used other natural remedies in the past when my leaves get mildew and have discoloration. The natural remedies didn't work for very long and the problem kept coming back. When I used Bonnie, it was like magic! My flowering bush is healthier and the blooms are more brilliant! This saves me so much time and money because I thought I'd have to start over. Thank you, Bonide!

Quality Plant Fungicide

I've liked this product, it can help with a lot of plant sicknesses for flowers, fruits, and vegetables. It says it can help with lots of different mildew diseases, blackspot, leaf and fruit spot, fruit rot, and late blight. It can also be used in dormant plants and hydroponic gardening. The instructions have you apply 2 weeks prior to the normal time you run into such diseases or once you see signs of them. You can reapply after 7-10 days until the plant is better. This comes with 16 ounces of ready to use product. The sprayer has two spraying options and an off mode. You can spray in a stream, or in a wider application. Having a lot of perennial flowers as well as growing a garden with fruits and vegetable every year, this product can be very useful. There's almost always some plant that has something wrong with it. So this kind of product is useful to have on hand when the disease is first noticed. A few of my plants also get the same mildew on it around the same time every year, so I find it best to pre-treat the area. I usually don't have to reapply when I treat it ahead of time. This product will be great to have on hand and I love that it treats lots of different problems because sometimes it's hard to tell what the exact disease is.
