Best blight resistant potatoes Sarpo Mira,Cara,Valor,Markies.
A plot doesn't get blight. It's not soil borne. Blight happens in August only when the weather conditions are correct - warm and wet. Hence the problems the last two years. If you don't want to spray - try the Sarpo types of potatoes that have some resistance. BUt if you plant earlies you can avoid the main period when blight attacks. Grow your tomatoes in the greenhouse too or just risk it as I did last year.
I have tried the Sarpo varieties - but not in a year when blight was bad on my plot so I can't vouch for their resistance!
When persistant daytime frost dropping to below -5degC at night is forecast, the average shed doesn't provide adequate protection if the potatoes are just in a hessian or paper sack. Being mainly water, potatoes attract the frost and need a lot of airy thermal protection.
As to blight the Sarpo Mira and Axona potatoes are extraordinarily blight resistant and I have grown them surrounded by rows of blight-hit spuds of other varieties, no problem. As well as earlier lifting, just keep the shears at hand - if our crops are hit we promptly remove all the haulms that are hit or suspect and then burn them. Little risk of the spores having been washed down in to the soil to infect the tubers - it works a treat.The crop can then be lifted asap with great results, you can even afford to allow a little delay before lifting as long as you do not irrigate and there is no rain.
