If you’re building a vegetable garden, avoid planting eggplants, peppers, tomatoes, and other related vegetables in the same land more than once every three years. In an ideal situation, you should plant corn after harvesting tomatoes during a rotation crop. Corn supplies plenty of organic matter, and it doesn’t attract disease organisms to ambush tomatoes.
Tomatoes (Solanum Lycopersicum) is a flowering plant that’s part of the Solanaceae family. Tomatoes can be grown on most soil types, ensuring that it has room to be well-drained. When looking for the diseases and viruses mentioned above, check the leaves, roots, flowers, and stems. Compare it to other healthy tomato plants and look for dissimilarities and insects.
To grow healthy tomatoes, read below about the common problems in tomatoes that you may encounter:
Problems created by Fungal Pathogens
Your tomatoes can be affected by blights and viruses.When detecting signs of early blight, you will see brown spots on the leaves of your tomato. You will know that it’s early blight if there are rings that look like a target in every brown spot. Surrounding the brown spots are yellow leaves up until it becomes brown, and it’ll fall off.
A fungus called Alternaria solani causes early blights. They can live on your soil during winter. Suppose these happened to you before and you planted your tomatoes in the same spot. If so, there is a high possibility that this will happen again.
As mentioned above, crop rotation is a must as it prevents the new crop from contracting early blight. If you plant eggplants, tomatoes, or peppers in the same spot, there’s a good chance that your crops will get infected with the disease.
The initial symptoms of this disease are when the leaves turn pale green, or it has pale yellowish spots on their surface; this enlarges and turns into yellow. Leaf molds are because of the fungus Fulvia fulva. The first observable symptom is older leaves nearing the soil where the air is high in humidity and poor. When you first detect the symptoms, go to GardenersPath to research how you can resolve the problem; it includes information that will surely help you.
In humid air movements, the spots in the lower leaf on the surfaces are covered with gray spores that are almost velvety-like; the fungus produces these spores. IF the infection in your tomatoes is severe, the spots merge, and then your foliage will be dead. The fungus can attract not only foliage, but stems, fruits, and blossoms.
A fungus called Colletotrichum phomoides infiltrates your ripened tomatoes; you will see a dark circle that looks like a bull’s eye on the bottom of a tomato or the end of a blossom. It looks mushy and almost like it is about to rot. The fungus loves moist and hot weather. If you have overhead irrigation, this item is the culprit in spreading the plants with infected soil. Change your watering methods so that the water drips on the roots and not the other way around. Finally, harvest your tomatoes immediately when it’s ripe.
Problems created by Viral Pathogens
Tomato mosaic virus (ToMV)
The tomato mosaic viruses are among the oldest plant viruses. Spreading the virus is easy and can cause your leaves to be yellow and be stunted. As a result, it reduces yielding and loses its ability to stand.
It can cause your tomatoes to be ripe unevenly, causing even more, less yield. The tomato mosaic virus is a contagious virus, and the vegetables near the plant can get the disease. It’s hard to detect the virus, and it’s also hard to compare it to the closely related tobacco mosaic virus.
You can’t detect if the virus has grown because it can show at any part of the plant’s growth, and the virus can infect all of the plant elements. It has a mosaic appearance and it is generally mottling on the tomato’s foliage. When infected, the plant leaves can look like ferns with dark green regions raised; they can also be stunted.
Tobacco mosaic virus (TMV)
As mentioned above, it’s hard to differentiate the two viruses, even if it differs genetically. This virus, just like the tomato mosaic virus, is one of the oldest and persistent viruses that can kill your plant. You’ll know the tomatoes are infected with the tobacco mosaic virus when the leaves have yellow-green mottling. The tobacco mosaic virus can stunt your plant’s growth; the flowers and leaves can be smaller, distorted, or curled.
When you’re educated about preventing problems and how the different pathogens can affect your tomatoes, you’ll have a bigger and healthier yield of your own tomatoes. The issues you encounter will always have solutions and methods for how to resolve them. Ensure that the food you’re feeding to yourself and your family is healthy.
