Do you want to know if a black spot on tomato leaves is harmful to human health? This is one of the frequent questions raised by gardeners and farmers. The truth is that a spot on the surface of the leaf is not harmful to humans. What is harmful is when the spot affects the plant’s vascular system. That’s when it can lead to poor harvest or early rotting of the fruits. Below are some reasons why this kind of spot is hazardous to human health:
* The Spots Are Puffy – They’re not very dark. Although they may be very small, these spots do not look like they’re going to pop up any time soon. Some people even wonder if they’ll grow back after a rain. Of course, popping them would mean killing the plant as a whole. To avoid such loss, it’s best to leave the black spot alone if you don’t want your crop damaged.
* It’s Around Longer – A leaf spot doesn’t last long. It grows in just a few days. It is also pushed around by wind and water flow. That means it is more exposed to sunlight and heat. To maximize its life, plants need sunlight and cooler temperatures.
* It Has a Longer Leaf – Some species can produce a very long and thin leaf. This one is quite rare though. Its usual form is about half an inch. Other forms have thicker and fuller leaves. So, don’t think you’re getting a big surprise by seeing a big leaf with a black spot on it.
* It Has Rust – Most of these pests come from iron-fisted soil that is still too wet for most species to survive in. If the leaves look really dry, that may mean the area is still too moist. You really do not want to try to take on this challenge if you can help it. If you’re not sure, ask a professional pest control company for help on how to deal with the problem of is it black spot on tomato leaves.
* It Has Plants Close Together – Closely spaced leaves meaning the nearby plants are susceptible to pests like aphids and lacebugs. The plant nearest to the main stem is typically the first one to get infested. Try to keep some of the flower heads together if you plant tomatoes close to each other. It’s okay if part of the plant is damaged or killed. The aphids won’t be able to feed from it.
* It Has Too Many Spots – A tomato plant with a lot of spots (no matter how small they may seem) is an invitation to pests and disease. The leaves will appear dry and the surrounding soil may look unhealthy. The plant is actually decaying. If you notice any problems with its leaves or soil, get rid of it as soon as possible.
Is it black spot on tomato leaves really harmful? No, it is not as harmful as it sounds. The damage is typically only superficial. This kind of damage usually doesn’t kill the plant. If you are growing tomatoes or just keeping them around, you probably don’t need to worry about it.
* It Has Been Laid Out – There may be some reason that leaves have been laid out horizontally for a long time. The roots have probably rot. In this case, it is usually the leaves themselves that look dead or dying. In extreme cases, the roots may have died also.
tomato plants require plenty of sunlight in order to grow. Too much sunlight can cause tomato plants to develop a dark green color. This is called “shade” and is very unattractive. On the other hand, too little sunlight can cause the leaves to turn a light color or turn brown. This is called “tone” and is actually better for the plants than shade.
Tomato plants don’t need to be exposed to sunlight for long periods of time. If you live in a part of the country that gets a lot of sun, plant your tomatoes in a sunny area. If they still need a lot of sunlight, make sure you plant them in pots instead of in large planters. If you find that your soil is too dry, add some water to the soil and let it sit for a while before using.
