Need some help

[cariann88]

I think I have powdery mildew on my tomato plant that I transferred from the greenhouse to outdoors the other day. I have only just noticed that the leaves and a bit of stem is covered in white spots.

Is there anything I can do to try and get rid of it?

[cariann88]

Is neem oil or Horticultural oils any good? If so has anyone ever used them to get rid of powdery mildew?

Or is there anything else I could use?

Now I think it's spread to....

Sweet corn


Beetroots


And Brussels sprouts

If you are growing under cover increase the ventilation. Inside or outside nip of leave that are affected and if you are organic spray with a dilute solution of half fat milk and if not a fungicide it it doesn't look like powdery mildew to me.

Difficult to tell from your pictures but I doesn't look like mildew to me either. Is it actualy a white powder you can rub off with a finger? I have asked for neem oil at several garden centres and they don't know what it is! As roitelet says semi skimmed milk or a weak solution of baking soda (teaspoon to litre ish) does help, but seems best if sprayed before they get it. Apparently they change the PH of the leaves and the mildew doesn't like it. I am plagued by it in my garden and have never found anything of much use.

Here you go Bill HH, there are various brands available. I bought one recently as I work with kids and want to keep the nits away! Also gets used on the dogs to keep fleas and ticks away. The stuff stinks but you get used to it.

I'm away to mix some up in a spray bottle to spray on the courgette.

Update: Right, that's the spraying done and slugs picked. Wonder if it helps keep them away too? Must experiment...

At that rate of spread it isn't powdery mildew.

2 thoughts (1) invasion of white fly, to the newby they look just like little white spots, try rubbing them of with your finger. (2) Not all plant leaves are perfect, many of my brassica leaves appear to have little white spots and other marks on them.

I have rubbed the leaf and nothing has come off it. The tomato plant just looks lifeless as the leafs have started to curl.

I have manage get a close up of one of the leafs.


This is what the plant looks like now.

This is PM on one of my courgette's from a couple of years ago as you can see its not quite the same. We put my brain cells to work.

I see they are in pots can I ask how you are feeding them?

[roitelet]

Could it be damage from water on the leaves and the sun scorching them? Are any of them turning brown?

A lot of plants are not as pretty as other years,also that's the difference between home growing and the supermarkets sprayed to death things,this is proving to be a really weird year again,as long as the fruits produced are well,i would not worry,

Those toms in the first photo look wilted. Are you watering enough? They dry out quick in pots, the leaves with all the patches on look like where the leaves have dried up and the sun has scorched them?
How often are you watering? Are you watering from the top or the bottom?

I am using easy feed - tomato soluble
