Blight spray

[Lincs Lass]

Spuds in the garden are just about to flowering stage ,its getting warmer again after the rain so Im thinking its blight spraying time ,,too soon yet or prevention better than cure

 

[cricketandcrops]

prevention always better than cure with blight, very difficult to control, I would say blight alerts will be going off round here now with the rain, and now how muggy it is outside, perfect blight weather IMO

 

[Lincs Lass]

That was my thinking , the years of planting and lifting them ,I should know when but ive been along time out of agriculture

 

[Boohoo]

I'd get them sprayed as soon as you can, although I'm used to the Northern Ireland climate. I sprayed mine a few days ago and the most advanced are 3 or 4 weeks from flowering.

Oh if only - no copper or any other products approved/offered to amateurs nor to organic growers. Yet French gardeners can buy copper products. Potassium phosphate plant tonics might, ahem, promote healthy growth that resists disease.

Better way might be to grow second earlies, in drier eastern regions anyway, they are usually safe in store by the end of August.

Then I found this
Bordeaux Fungicide Recipe
All the ingredients are available at garden centers, and the recipe that follows will help with making Bordeaux fungicide. This recipe is a simple ratio formula that most home growers can easily master. Copper fungicide is readily available as a concentrated or ready to use preparation. The homemade recipe for Bordeaux mix is 10-10-100, with the first number representing copper sulfate, the second is dry hydrated lime and the third water. Bordeaux fungicide preparation weathers better on trees than many of the other fixed copper fungicides. The mixture does leave a blue-green stain on plants, so it is best to keep it off any that are near the home or fencing. This recipe is not compatible with pesticide and can be corrosive.

Yes, you can buy the ingredients, but it is not technically legal.

How the organic brigade have been allowed to use copper for so long is beyond any logic I’ve ever seen when conventional farmers were stopped from using it years ago!

Google brings up other suppliers that are around half the price but they're all in Ireland. It might not be licensed for the UK.

This stuff? These are agricultural active ingredients & it's basically Infinito in a smaller and far more expensive package. My potato agronomy is pretty rusty as I haven't grown them for 13 years. Propamocarb is a systemic protectant. Not sure about the other one nor how much kickback there is but Infinito's label says to stop treating once 1% of the leaf area is infected.

I did not google it , just relied on advice from another site.
