Bonide Rose Rx Systemic Drench, 32 oz Concentrate, Garden Insect & Disease Prevention for Roses, Flowers and Ornamentals

Works great for my roses. Keeps them healthy all year long. Less is more when measuring out the dose.

Amazing product! I’ve purchased 6 bottles over the years and will continue buying. Prior to discovering this product, my roses never really thrived due to black spots and aphids. Well, not anymore! This stuff does wonders and my roses are vibrant and healthy! It’s easy to use too! I truly stand behind this product and consistently recommend it to fellow gardeners.

I have been using this on my 20 rose bushes for a couple of years. After using it every six weeks (a total of four times) during the season last year, I noticed a couple of my roses that were very prone to sawfly damage in the Spring had very little this year, so I see that as a win. Along with bi-weekly fungicide spraying and monthly fertilizing this year, my roses have never looked better! I will continue to use it every season from March - September.

This 32oz bottle will drench, using 1 quart water mixed with 2 oz product, 17 roses. Exactly 17. Not even close to 20. Plan accordingly. Does work wonderfully to prevent rose diseases and pests.

Since I started using this as a spray on my 30 roses of many varieties they have been much healthier. Reduced insect damage, reduced fungal problems and generally not much to worry about. I just spray this product and use a good rose fertilizer.

This is a good product. It got rid of the gnats in my house plants.

Well I am going to be honest with this review. I havent used much of the competition but this really exceeded my expectations. We had a very very very wet spring this year and moisture is a roses worst enemy. I had so much black spot on my roses that I could not keep up. I was spraying the roses at a rate I was outside with the roses pruning and spraying more then my other house hold choirs. I bought a bottle of this at the local shop figuring I would give it a chance and at first I did not notice any thing new. (Obviously it takes a short period of time to work as it has to travel through the rose and in to the leaves) but after just one month the new leaves are so green and shiney with no sign of problems at all. I even had one rose that had shown signs of the RRD so I pruned it heavily, applied this and sprayed the rose constantly and so far the rose is growing so fast and beautiful it has not even exhibited one sign of the RRD after a period of 2 years that I have had it. I cant say it killed or stopped the RRD but I will say it really has took it from the ugly red stem that had it to the most beautiful abundant blooming rose I have yet to see. I even have neighbors and such stopping by to take photos of my roses. I am definately convinced while I cant say 100 percent this product is behind all the beautiful results I have seen I can definately say they have improved for some reason since I have began applying this.

This is my first year using this product. I started using it when spring first started and then at the recommended intervals. First impression is that it does not mix well, no matter how much I stir there are still clumps. Not sure how this impacts the effectiveness. I can say that I have noticed a difference in the amount of blackspot my roses get. It took longer for them to develop it and it isn't as bad as last year, but it is still there. Although it says it also keeps pests away I can say it has done nothing to deter the insects. It seems to work better on the roses that aren't predisposed to blackspot in the first place. Not very impressed so giving it 3 stars since it does seem to be doing something.
