Understanding Disease Resistant Tomatoes

There are dozens, if not hundreds of diseases that can fall upon your tomato crops. Some are admittedly more common than others, but some are not.

With so many factors affecting the resistance levels of tomatoes, it is crucial to take some time to understand the plants that you’re about to crop to avoid attending to all these unnecessary tomato diseases.

Before you make any purchase of any tomato plant, memorizing the resistant codes can be overwhelming so be sure to check in with the supplier or seller if the breed you chose is a disease resistant type. 

Do take note, however, that disease resistance doesn’t mean total immunity. Depending on your region’s climate, or your soil condition, even supposedly some of the best disease resistant tomatoes may well be prone to the diseases.

Read on to understand the types and steps that one should take to reduce tomato crop loss.

Selecting The Right Tomato Breed For Your Garden

One of the crucial steps before planting the seeds is to understand that even though there are a variety of disease-resistant tomatoes, some may not thrive well in your garden as opposed to someone else residing in another region.

For example, if you’re living in the eastern of United States, your tomatoes are prone to experience an early blight or septoria leaf spot diseases. The solution to these problems is to select tomato varieties that are resistant to these types of diseases.

A Quick Guide For Choosing A Tomato Breed

1. Accustom yourself to the resistant codes on the seed packages – There are some tips below with some of the general codings that you may find on the seed packages. A cool tip, bookmark this tab for your easy reference in the future!

2. Choose the best variety that suits your region – Choosing the disease resistant tomatoes is easy but there’s no guarantee that there’ll be no harm to them. At the end of the day, it’s best to select the best disease resistant tomatoes that suit your region. 

3. Identify the vulnerabilities of your region – The most crucial step is to discern the common tomato diseases in your region. Ask around your neighbors who are green with their fingers or have a chat with any local nursery owners. 

Or the easiest method would be to call up your local extension office to know which tomato diseases are often recorded by the local gardeners.

How to Choose Disease Resistant Tomatoes 

One of the main objectives of these modern hybrid development programs is the production of disease resistant tomato varieties. Resistance does not equate to total immunity, hence why there have been no successful disease free tomatoes just yet. 

Gardeners are encouraged to select blight resistant tomato seeds relevant to their gardens. To choose the best disease resistant tomatoes is to look on the seed packet or the plant label for the following codes:

AB – Alternarium Blight

A or AS – Alternarium Stem Canker

CRR – Corky Root Rot

EB – Early Blight

F – Fusarium Wilt; FF – Fusarium races 1 & 2; FFF – races 1, 2, & 3

FOR – Fusarium Crown and Root Rot

GLS – Gray Leaf Spot

LB – Late Blight

LM – Leaf Mold

N – Nematodes

PM – Powdery Mildew

S – Stemphylium Gray Leaf Spot

T or TMV – Tobacco Mosaic Virus

ToMV – Tomato Mosaic Virus

TSWV – Tomato Spotted Wilt Virus

V – Verticillium Wilt Virus

Types of Tomato Diseases

Understanding the various types of tomato diseases can give you an upper hand in saving your tomato plants from these common diseases listed below.

1. Early Blight

Early blight can affect the fruit of the tomatoes, the foliage and the stems.

Symptoms: The perimeter of the leaf may turn yellow and you’ll see dark spots with concentrated rings forming on the older leaves. This type of fungus only attacks after the plants set fruit.

Management: mulching, crop rotation, sanitation, fungicides, staking

2. Late Blight

Affects the stems, leaves and fruit of the tomatoes.

Symptoms: A ring of white mold can form around the spots in wet weather. They are often greasy looking and are irregularly shaped dark brown blotches with green gray edges. The spots will eventually turn dry and papery. 

The stems may eventually have blackened areas and the fruit can turn mushy from a secondary bacterial infection. 

Management: sanitation, fungicides, disease-free planting material

3. Southern Blight

Commonly manifests itself as a white mold growing near the soil line on the stem. 

Symptoms: Both the outer and inner stem becomes discolored and that round, dark spot start to form on the lower stem near the soil. This type of fungus prevents the plant from soaking up any nutrients or water. 

Management: fungicides, deep tiling, crop rotation

4. Septoria Leaf Spot

Often mistaken for a Late blight, it’s a fungal infection that only affects the leaves but not the fruit.

Symptoms: The infected area appears as small, dark spots that will grow into a ¼-inch diameter. It gradually changes into a tan or gray color, and the leaves will eventually wilt and fall.

Management: weed management, cultural practices, sanitation, fungicides, crop rotation

5. Anthracnose

A very common fungus that always targets the fruits that causes them to rot.

Symptoms: Small, sunken, round spots appear on the fruit. The spots gradually increase in size and darken in the center.

Several more spots may emerge as the size enlarges. Poorly drained soil and wet weather are the primary motivation for the development of anacthrose. 

Management: cultural practices, fungicides, sanitation, crop rotation

6. Bacterial Speck

Can be difficult to control when favorable environmental conditions are present and when the disease pressure is high.

Symptoms: Small spots that are brown in the centre and have a yellow ring on the perimeter of the spot. They are usually small in size but if overlapped, they may appear larger and irregular in size. 

This type of disease can spread to the fruit if early measures are not taken.

Management: seed treatment, sanitation, crop rotation, fungicides, cultural practices, pathogen-free seed

7. Blossom End Rot

Generally caused by a lack of calcium availability during the fruit set. Factors concerning the fungus presence may be due to too much high-nitrogen fertilizer or uneven watering. In short, it’s not a disease but a physiological disorder that will result in the loss of fruit.

Symptoms: Black/dark brown spots develop at the blossom end of the fruit and the spots look water-soaked.

Management: deep watering, crop rotation, cultural practices, sanitation

8. Verticillium Wilt

The name can be misleading as the leaves will never appear to wilt but will only be dried up and turned yellow. 

Caused by a soil-borne fungus, which can persist in the soil for many years therefore a selection of resistant varieties and crop rotation is crucial. 

Symptoms: The symptoms tend to start on the older, lower leaves and eventually move upward. You’ll spot yellow blotches that will eventually turn into brown dead spots. Verticillium wilt affects the production size of the fruits as it stunts the plant.

Management: sanitation, fumigation, crop rotation, resistance

9. Gray Wall

Essentially it’s a ripening complication as there are no known associated pathogens.

Symptoms: The appearance of ripe fruits may look mottled with the presence of green or brown areas inside the fruit. Green fruits may have a flattened, gray blotch or gray cast.

Management: seed treatment, sanitation, crop rotation, fungicides, cultural practices
