It is another chemical active used within the crop protection industry which has recently undergone revocation. The process meaning it will no longer be legally registered to be sold for use within the UK.
CTL is a nonsystemic fungicide, which is foliar acting with some protectant properties. It works by preventing the germination of spores and those facilitating plant infection. Products containing this active have been very influential to disease resistance programmes, due to being a multi-site active which combats numerous diseases in a very wide range of crops since its introduction in 1964. CTL has great efficacy against Septoria, a very influential disease to yields which favours our UK climate, and also Ramularia in Barley.
There has been a phased implementation of withdrawal, with the dates as follows,
- 20th November 2019, last date for the sale and distribution
- 20th May 2020 last date for the disposal, storage and use of existing stocks
If CTL is required within your spray programme, it needs to be ordered now. Supply is likely to diminish as we approach the sell out date.
