You can identify problems by observing the symptoms. Once you know the underlying cause, you can treat the problem. There are some problems which arise due to unsuitable weather conditions.
These, unfortunately, cannot be controlled. For all other problems, there are treatment options that can help you overcome them. Here are some basic problems that are faced while growing tomato plants in your garden.
As a result, green patches appear here, which later become yellow instead of red. The solution to these is taking proper measures so that fruits are not exposed to the sun's heat. Sun scald is one such problem arising when there is heavy defoliation or pruning of leaves due to infestations of pests, worms etc.
Blossom End Rot
The early symptoms of this disease are slight tan and black spots at the blossom end of the tomato. The size of the spot increases and the fruit rots. This can happen if the temperature is a combination of extreme cold and excessive heat at the time of blossom set. Under such circumstances, deficiency of calcium can take place.
It also occurs due to irregular supply of water to the plants, or excessive use of nitrogen fertilizers. In order to manage this problem, all the affected fruits should be removed. Watering the plants properly can prevent the problem from getting worse.
Rot in Roots
This is caused due to fungal infection. You cannot control the fungus that causes root rotting. Usually, these fungi develop if the drainage of the soil is not proper, or due to excess watering.
So, this disease can be controlled by taking proper measures for soil improvement and adequate watering of the plants. You should not plant tomatoes or any other species in areas of the garden that have poor water drainage.
The most common symptom of this disease is lowering of the leaves that are located in the lower portion of the stem. Brown-colored streaks often develop at the midribs of the leaves, which may later extend to the stem as well.
Many other diseases have similar symptoms. So, to identify bacterial canker, a laboratory test is required. Once the disease is detected, the plant should be destroyed. The diseased plant should not be used for composting.
This disease affects the fruits, foliage, and stems of the plants. It is caused by a fungus. Usually, the symptoms show up when the weather is hot. Initially, it attacks the old leaves and black spots appear on them. Then, the affected leaves become dead and fall down.
As a result, the fruit suffers sun scald. In case of a heavy infestation, even the stems and fruit come under the attack of the fungus. All the infected plants should be removed from the ground as soon as possible.
The debris of the diseased plant should also be removed from the ground. There should be enough space between two plants to help in better air circulation. Sulfur or copper sprays will be useful in controlling further infection.
Many of these problems can be eliminated if you follow some simple practices. Keeping the garden free from any plant debris, removing all weeds on time, regularly rotating crops in the garden, etc., are steps that will not only keep away infestations of pests and insects, but will also help yield healthy tomatoes.
