Not only people love to eat tomatoes. People have plenty of rivals. Who are they and how to win the battle with them so that the harvest of healing and tasty fruits will go to the one who took care of the plant?
Why are tomato leaves curled
The reasons for leaf curling can vary.
During the period of active ripening of fruits, nutrients tend from the stem and leaves to the tomatoes gaining weight and ripeness. This leads to starvation of the leaves, and they twist in order to call people for help with their appearance. The lower leaves and the leaves of the middle tier fall into this situation.
If the upper leaves begin to curl, becoming like "chicken feet", then there is a lack of calcium in the soil. We purchase calcium nitrate and carry out foliar feeding in the evening, at the rate of 20 grams of nitrate per bucket of water.
Why tomato leaves turn yellow
If a person's life is counted in years, then the life of a tomato leaf is in days. After 70-90 days, the leaf becomes old, and it turns yellow. Aged leaves should be removed from the plant so that the air passes freely between the bushes, and also so as not to leave a chance of a disease called late blight.
If yellowness on the leaf appears from the central lobule, then the plant does not have enough potassium.
At high humidity in the greenhouse and an air temperature between 22 and 25 degrees, conditions are created for plant disease with brown spot. The disease begins with the appearance of light yellow spots on the lower leaves, and then rapidly spreads throughout the plant. Light yellow spots gradually turn into dark brown, covered with a white coating.
To overcome the disease, it is necessary to reduce the humidity in the greenhouse and treat the leaves with a 0.1% solution of copper oxychloride.
Light spots between the veins of a tomato leaf
The lack of magnesium causes lightening between the veins of the leaves of the lower and middle zones of the plant. You can help the tomato by foliar feeding with Epsom salts (magnesium sulfate). Top dressing should be carried out after 1 - 2 weeks, adding 10 grams of fertilizer to a bucket of water. Such feeding cannot be combined with feeding with calcium nitrate and potassium sulfate.
Brown spots on the top of the fruit
Brown spots on the top of the fruit can be due to a lack of calcium, or attacks by fungi that cause top rot.
Late blight
The causative agent of late blight or late blight is oomycetes, a special type of microorganism that is similar to both fungi and bacteria. They develop most often in water, and therefore they like to attack greenhouses and tomato beds in high humidity and low temperatures.
Since these pests are great lovers of plants of the Solanaceae family, it is not necessary to plant potatoes, tomatoes, eggplants close to them.
The whole plant is affected by the disease. Brown spots appear on the stems and leaves, and the tomatoes turn brown, turn black and become hard.
The disease is fought by stopping watering, ventilating greenhouses, treating plants with 0.1 percent copper oxychloride.
Cracking tomato
It can be very annoying when beautiful large tomatoes crack, which spoils their appearance and can become a reason for illness. The reason for this behavior of the fruits is uneven watering of the soil. Sharp fluctuations in its moisture content are reflected in the formation of fruits.
The main pests of tomato
Peach aphids and whiteflies are especially annoying pests in plastic greenhouses.
They fight them by destroying weeds, disinfecting greenhouses, or resorting to the help of insecticides.
