Will lime sulphur get rid of rust fungus in Colorado spruce trees?
If so how much should I use on each tree and how often should I use it.
Mark,
fungicides used to control rust on Colorado Blue Spruce should be sprayed in spring as the new needles begin to elongate. Dry wettable sulfurs are available under many trade names. The microfine wettable sulfurs are usually much less injurious to foliage than liquid lime sulfur, but their use during hot weather (above 80 F) may result in some leaf burning. Flowable sulfurs are also available from several manufactures. The most common formulation is the 6F which contains 6 pounds of sulfur per gallon. Due to smaller particle size, flowable sulfurs may be a bit more efficacious than wettable powders. Flowable sulfurs are often preferred to wettable powders because they do not create dusts that can be inhaled during loading and measuring operations. A major problem with the use of sulfur as a fungicide is the lack of residual protectant activity. Sulfur only provides about 3-5 days of protection. I’ve seen mixed results from sulfur used as a fungicide to control rust on other plants. There are many different rusts, and therefore, many different fungi that cause rust. Rust on Colorado Blue Spruce is generally not a common problem, so you are not going to find a lot of info on the efficacy of sulfur/lime. I wish I could tell you this will work, but I think you are just going to have to try it to find out. Use enough to wet out all sides of the new needles.
Plant damage caused by lime-sulfur is most severe during dry weather when temperatures reach 80 degrees to 95 degrees F. Spray early in the morning or late in the evening to avoid burning of foliage. Lime-sulfur is corrosive to the eyes and harmful if swallowed, inhaled, or absorbed through the skin. Appropriate precautions according to the label should be taken when applying lime-sulfur. Thoroughly read the label before purchasing, handling, or applying lime-sulfur.

lime sulphur dip/shampoo for dogs?
Does anyone have any idea where i can buy this for my dog in the uk?
If the shampoo is not made for dogs don’t use it. Soaps and shampoos for humans actually burn animal skin. Ever felt how dry your hands feel after you’ve washed dishes? And dish soaps are supposed to be gentle. Dog and cat skin is alot more sensitive than human skin and something like dish washing liquid will actually burn their skin. Why on earth would you want to use lime sulphur dip? If you actually care for your dog you would ask your vet for an appropriate shampoo.
