Most blight-resistant tomato varieties

While blight resistant tomato varieties are not immune to early blight or late blight, they have a stronger resilience than other types of tomatoes. By growing blight resistant tomatoes, you have a better chance at cultivating a healthy crop.

Tomato blight is a common problem that attacks tomato leaves, stems, and fruit. There are two types: early blight and late blight. Both are caused by different types of fungi. Early blight attacks leaves and stems. It causes plants to under produce. Late blight produces spots and mold on leaves and fruit and can overtake a plant within days if not treated.

Breeders continue to develop blight resistant tomato varieties. During summer 2010, researchers at Cornell University tested varieties that are resilient to both early and late blight. Until they are commercially available, gardeners will have to choose tomatoes that have already proven to be resilient to one or the other – whichever type of blight is most prevalent in their local gardens. For now, one of the best ways to prevent early blight and late blight in your crop is to choose and grow blight resistant tomato varieties.
