I sprayed my earlies with Dithane once how soon can I harvest them after this spraying. It has not stopped the blight and I now want to harvets all the crop affected to prevent the blight getting to the roots.

Dithane is a protectant spray containing manganese and zinc. It is applied about once a fortnight, or when blight warnings are given.
It only works for a time as it is washed off and degraded, so one application does not work on its own for a whole season.
The withdarawal period is 14 days after last application.
