| What's the best way to use a hose-end sprayer for spraying concentrated Daconil? I tried it once and ended up with loads of white film spots all over my roses and other perennials because I guess it wouldn't mix right in the sprayer. Should I dilute the Daconil with water first and spray the dilute?
Thanks all, kentstar |

| If anybody speaks from experience with this particular combo, listen to them, not me. But here are some generalities: 1. Daconil is supposed to leave a whitish coating, but it shouldn't be thick and opaque. You could try mixing some water in. 2. Hose-end sprayers are very inaccurate in the mixture they deliver. I think you should be using a pump-up tank sprayer (around $15). |

| I would be afraid to use a hose end sprayer because of the possibily of back up into the house drinking water. |

| Agreed Michael. Daconil is effective but does leave white spots and residue. If you have to use any chemical, it's far better to use as little of it, as precisely as possible. A whale of a lot cheaper that way, too. Kim |

| Don't use a hose end sprayer. It's not accurate enough. You don't need to soak your roses in the solution, just give them a very fine spray to cover the leaves. Use a tank or handheld sprayer. |

| That's not going to give you any kind of control over how concentrated your solution is, or how much of you it apply. You need a tank sprayer (about $20 at Home Depot). Mix according to the label directions and spray as a fine mist. You'll use a lot less material and get it on the leaves where it belongs instead of all over the place. |

| Ok, thanks. I will look for another sprayer that will work more precisly and coat the leaves with a finer spray. Probably is better anyways for anything else I decide to spray like fertilizers too. :) |

| It is impossible to get your spray where it needs to be,which is on the underside of the leaves. |

| Now a contrary word from the Queen of Spray.... The Gilmour brand hose end sprayer with meter dial is an excellent and reasonably precise, accurate sprayer. It costs about $20 and you can often find them at hardware stores, as well as online. Use the spray stream diffuser to achieve a fine spray. It's not as fine as a mist. The Gilmour is powerful and you can spray 100 roses in less than 10 minutes. For spraying Daconil or wettable powders such as Manzate, I follow the sprayer directions for "pre-mixing" the chemicals. It also helps to use a surfactant in the mix to aid in a more even application of the spray. Be careful with that Daconil. It has a tendency to cause leaf burn, especially in hot weather. I've used the Gilmour for the past 8 years. I use it for gardens large and small. It's my go-to sprayer. It's an extremely versatile tool. If you'd like more information about the Gilmour sprayer, I have an article posted on the CharlestonRose.com, the web site of the Charleston Lowcountry Rose Society. |
