hey gardeners,

I have noticed this on my tomato today, snapped those 2 leaves as a precaution action. is it just normal sunclad or blight ?! what should I do ?!

I think you mean sun scald and no it doesn't look like sunscald:

sun burned areas will be beige or whitish, thinned out and crispy, look burned.

That looks like some kind of disease, not necessarily blight, perhaps septoria.

That's Septoria, I would know it anywhere an organic solution is liquid copper fungicide. Warning, I have found out the hard way that if you use it at even the minimum recommended strength, your newer leaves will curl. I always mix it half of the minimum rec. strength, and it works perfectly.

thanks kitty, do you have a link for this product ?!

Copper is frequently recommended as a fungicide. Depends on your philosophy whether you call it organic or not. Some organic gardeners would not.

Milder alternatives include baking soda spray (1 T baking soda in a quart of water with a little bit of oil to help it stick), 3% hydrogen peroxide sprayed straight from the bottle. Diluted milk works too, but works better as a preventative than a cure. Whatever you spray, be sure you spray the under sides of the leaves as well.

Naw, I just get it at HD or Loes, or any other garden supply. I don't care so much for putting milk on because bacteria like sugar, and milk is loaded with it. Even non fat milk. Copper spray is OMRI listed as acceptable. Some people worry that it is a heavy metal, but the plants actually need copper.
