Re: Dithane 945
Now that Bordeaux Mixture is banned, due to the copper in it, the only weapon against blight available to the gardener is Dithane. It protects the leaves from infection but does not kill blight infection already present.
In this regard, is dithane systemic?
Dithane® M-45 is a contact (non-systemic) and protective fungicide which prevents diseases by inhibiting the development of fungal spores on plant parts.
Similarly, it is asked, how do you mix Dithane?
Mixing Instructions for Knapsack Sprayer: Cream 9grms (1/3 oz) (1 level tablespoon) with a little water. Pour into a bucket and make up to 4.5 litres (1 gallon) with water. Apply as a fine spray covering to the upper and lower surfaces of the leaves. Agitate the mixture occasionally when spraying.
It's had its licence withdrawn and is no longer legal to use in the UK.
