Pea plant problem

Hi,

This year we decided to grow our pea's at home in the greenhouse, as getting to the allotment on a daily basis was going to be a problem.
But the plants have developed a white powdery leaf, can anybody suggest what this might be, i did see something that suggested that it maybe to do with poor air circulation - but they didn't give a treatment for it. we have moved the plants outside now, but they do look very poorly so is there anything that i can do?

Hi Neal and welcome to the forum

I think you have what is called : Powdery Mildew its a fungal disease growing in the greenhose hasnt helpded as it like still air plus the hot temperature but not all is lost , you can use Baking soda sprayed on hopfully one of the more wiser organic gardeners may be able to help .

What are you growing them in ??

Good evening Neal and welcome to the site. As Spruce says, your peas have powdery mildew, which is a form of Botrytis. Treat witha systemic fungicide suitable for use on edible plants. Legally, you cannot use anything which is not registered as a pesticide, so DO NOT use baking powder.:thumb::thumb:

 

Yes there's not much left in the systemic arsenal for us gardeners
However I'd wouldn't worry too much about non-approved solutions as I can't really see HMG or the EU going to the expense of prosecuting an amateur gardener for using a product such as baking soda on his peas.
We kill the moss on the patio with left over bleach solution after washing the kitchen floor - kills the moss but isn't 'approved' !

Another thing to try for botrytis is a 10% milk/water solution, it does work on cucumbers and I can see no reason why it shouldn't work on peas too. You can also try washing off the spores with either a hose or pump-up sprayer - it won't be a complete cure and you'll still need to 'treat' the plants but it should help reduce the infestation.

 

Isn`t Systhane still available?

 

Are we talking about this.....

ok thanks guys, shame the ID was to late to save most of my crop, but I've sprayed whats left with 100ml of full fat milk with half a level teaspoon of bicarb and made it up to one litre.
