How To Stop Blight By Growing Blight Resistant Tomatoes!

If you are looking for a simple way to keep blight from ruining your tomatoes this year, then the best way to success is by growing blight-resistant varieties. Not only are there many delicious and amazing options available to pick from, but they help to prevent blight from ever becoming a problem! 

If there is one thing that can leave tomato growers frustrated, it’s the sight of blight. Blight is a fungus-like infection transmitted by spores that causes tomato plants to quickly wilt and eventually die.  

Not only can blight affect the current year’s plants, but the spores can stay active in the soil for over 5 years, causing devastation to future crops as well. And what’s worse, once you see signs of blight, it can be almost impossible to stop. That’s why being on the offense is so important.

Blight can quickly take over and destroy otherwise healthy tomato plants.

One of the best ways to prevent blight from taking over starts with choosing the right varieties of tomatoes to put in your garden this year. These blight-resistant tomatoes will ensure that you get to make the most of the entire growing season!

What Is Blight

There are two main types of tomato blight: early season and light season blight. Early season blight occurs when late spring and early summer have been overly wet. While this type of blight isn’t always fatal, it can cause a reduction in your plant’s fruit production. 

Late-season blight is usually more of an issue and is almost always fatal for tomato plants. It typically starts to appear about the same time that your tomatoes start to produce fruit. 

First, the lower foliage will start to brown and die. Before long, the blight has worked its way up the entire plant. The fruit is also affected, causing dark brown or black spots on the tomatoes, making them worthless. 

At this point, the only thing you can do is pull the affected plant and toss it. The plant material isn’t even good for adding to your compost pile at this point since the spores can live in most home compost piles.

Late season blight is especially problematic. It takes over the foliage of the plants as well as the fruit.

That’s why prevention is the key to success. While there are some steps you can take to help avoid blight, planting and growing tomatoes that are naturally blight resistant is your best chance of avoiding blight, especially if you’ve had issues with blight in the past. 

Growing Blight Resistant Tomatoes – 5 Great Varieties

Natural genetic resistance to blight has been found in some varieties of tomatoes throughout the years. These varieties have been bred into many wonderful hybrids that you can find in most garden centers today. 

There are even some heirloom varieties available as well that are resistant to blight. And rest assured -There is no genetic manipulation occurring with these hybrid varieties – only selective breeding, so the seeds are still 100% GMO-free. 

One thing to keep in mind is that no tomato plant is 100% blight-proof. These plants simply have a stronger resistance to blight and are able to withstand an infection better if one were to occur.
