Mountain Magic is a famously late blight resistant variety, and it is also early blight resistant. Valentine, Plum Regal, and Juliet -- which are Roma/plum/paste types -- are resistant. But slicing tomatoes are more limited. Defiant, a determinate medium slicer, is resistant to early blight.
One of the most pest and disease resistant tomatoes is the 'Juturna' tomato. This variety is a determinate, meaning it has a compact growth habit and produces fruit early in the season. It also has good resistance to Verticillium and Fusarium wilts, as well as to tobacco mosaic virus.
Suttons blight-resistant tomatoes
One of the most versatile tomatoes we've ever produced, it's also heavy fruiting with harvests that continue until the first frosts. Crimson Blush Beefsteak F1 seeds: If you're looking for a beefsteak variety with superb blight resistance, this is the one for you.
Treating Blight
If blight has already spread to more than just a few plant leaves, apply Daconil® Fungicide Ready-To-Use, which kills fungal spores and keeps blight from causing further damage.
Gummy stem blight is a stem and leaf disease of cucumber, cantaloupe, pumpkin, and watermelon caused by the fungus Didymella bryoniae. This fungus also causes a fruit rot called black rot.
According to Dr. Barbara Ingham, food safety specialist with the University of Wisconsin Extension, you can safety eat and preserve unblemished tomatoes growing on plants with leaves, stems or adjacent fruit showing signs of infection.
Some of the protectant fungicides registered for late blight control on tomatoes and potatoes include; copper (i.e. Champ), chlorothalonil (i.e. Bravo), and mancozeb (i.e. Dithane).
'Jasper', 'Red Pearl' and 'Matt's Wild Cherry' are small fruited tomatoes with good resistance. Some heirloom tomato varieties have good tolerance to late blight. A few cultivars also have resistance to Early Blight (Alternaria solani, A.
The hardiest ones aren't always the tastiest, but the varieties I have found to be very hardy are Cole and Mongolian Dwarf. (Both are great in cooler climates/short growing seasons and both are open-pollinated.)
Better Boy tomatoes are disease resistant and often do not struggle with many of the most common tomato-related diseases. Always be on the lookout for pests that might attack the plant.
If you garden organically, adding compost extracts or teas can be a treatment. To create a solution that prevents and treats disease, add a heaping tablespoon of baking soda, a teaspoon of vegetable oil, and a small amount of mild soap to a gallon of water and spray the tomato plants with this solution.
If you get an fungal outbreak like 'Leaf Spot' or 'Early Blight' use hydrogen peroxide to get the diseases under control. My goal with diseases is to manage them down as to still get get great production from my tomato plants.
This spray of water and baking soda will change the leaf's pH from around 7.0 to around 8.0. This change is enough to kill and prevent all blight spores!
The fungus spends the winter in infected plant debris in or on the soil where it can survive at least one and perhaps several years. It can also be seed-borne. New spores are produced the following season. The spores are transported by water, wind, insects, other animals including man, and machinery.
Spraying fungicides is the most effective way to prevent late blight. For conventional gardeners and commercial producers, protectant fungicides such as chlorothalonil (e.g., Bravo, Echo, Equus, or Daconil) and Mancozeb (Manzate) can be used.
Due to the potential risk of long-lived resting spores being produced by the blight pathogen (see the 'Biology' section, below) it is best not to use the soil or compost from a blight-affected greenhouse crop to grow tomatoes in the following year.
Pickleworms are the larvae of the pickleworm moth (Diaphania nitidalis). This widespread pest ruins summer squash, their favorite meal, by burrowing into and feeding inside the fruit. They also attack cucumbers, cantaloupes, and pumpkins.

Symptoms: Chewed leaves, irregular, jagged holes.
