What's wrong with my watermelon leaves and can I save tomatoes with bad leaf spot

[heather smith]

I have over the past week noticed that my sugar baby watermelon leaves have started to look like this in the picture. What's wrong with them and can I fix it? I tried Google images but it's so hard to figure out what it is. I also have been battling leaf spot disease on all my tomato plants and they are pretty much barren of foliage now :-( so frustrated this year with all these foliage problems in my garden. Some of the the tomatoes are coming out with brown spots that are rotten on them as well, the beef master ones have it the worst. Should just pull them all up and give up? I have treated with copper and fungicide spray already

 

[so lucky]

Do you live in an area that has gotten way too much rain?

I liveon the southeast coast of North Carolina, and we have had times of way too much rain and then weeks without a single drop and high heat and humidity

looks like you might have Alternaria Leaf Spot on your melons..

a good fungicide for melons, tomatoes, corn etc is mencozeb made by bonide.... copper is good as well as long as it does not wash off.

have a photo of your tomatoes problem?.... i deal with blossom rot not as bad this year...

What the major said. I haven't had a problem with it, but saw many community gardens that looked like that the past two years. Effected most of the squash, melons, and cukes as far as I could see.

I just moved to north carolina this year from Massachusetts so I'm having a real struggle figuring out this new climate, but so far this year I have dealt with blossom rot on my early girl tomatoes which I finally fixed, then leaf spot that seemed too spread like wildfire over to the big boy and beef master tomatoes, then we had a tornado that took our a bunch of my garden and flowerss, then we had a huge infestation of snails and slugs which I seemed to get under control as well. We also have Japanese beetles that I'm just barely keeping under control by picking them as I see them. I also noticed spider mites on my cukes and my cucumbers are always just a pale green and haven't been getting a deep green color so they don't taste good, but they start to turn yellow if I try and wait it out for the green to come in. I am out at the garden store and when I get back I will take some pictures and post them. Will the alternaria leaf spot ruin the watermelon fruits? I'm so bummed out ... pics in about an hour

you're right in the middle of rain alley for north carolina, sandy soil does not help either.
cucumbers love lots of water and a good balanced fertilizer 13-13-13
for the slugs copper or a small dish of beer slightly buried in the soil where they can not get out...
for the mites a good insecticidal soap containing... bt
for j.b. neem oil

as for your tomatoes it could a number of things..love to see a photo of them when you get a chance...

as for the dry spells keep the ground around your plants well watered 1-2 " per week maybe more since you have a sandy soil and only water at the base of the plant ,not the plant itself thats a good way of spreading diseases....

keep up your hard work it will pay off in the long run....

Everything is in raised beds because our soil is terrible and we also live in base housing on a marine corps base and I'm not alowes to dig up my whole back yard lol, but I'm loading pics now. Just yesterday I went and took off all the tomato leaves with leaf spot and trashed them and now just in one day more tomato leaves are spotted, I have treated every 7 days with the copper spray for the leaf spot, I also use a 10-10-10 fertilize, but pics are coming now

And I have been watering now with a watering can right at the base of each plant. I also have different types of lettuce and peppers and broccoli that hasn't been affected at all, but my corn did have some damage from the beetles

not an expert but from what i see could be the following...everyone chime in if i am wrong....
photo 1 leaf spot
photo 2 could be powdery mildew
photo 3 bug bite and lack of water
photo 4 looks like early blight
photo 5 stink bug bite.
photo 6 blight again
photo 7 early signs of late blight
