Spider mite control measures on tomatoes

Often, vegetable growers are faced with a problem such as the appearance of a spider mite on tomatoes. People first learned about this arachnid in the 19th century. Then they gave it a name - Tetranychus urticae. Translated from Latin - common spider mite. It feeds on arthropod sap of plants. One of the favorite fruits is tomato. Therefore, a spider mite on tomatoes is found quite often, including in greenhouses. If there are no tomatoes, the tick moves to peppers, eggplant, cucumbers and other vegetables.

An infected plant may die. This is due to the fact that rapidly multiplying parasites bite the leaves, they turn yellow, small dots appear on them, which leads to the drying of the green mass. Due to a violation of the photosynthesis process, tomatoes cease to develop.

Where does the spider mite on tomatoes come from

The size of the arthropod is scanty, it barely reaches 0.2-1 mm. To see it with the naked eye is unrealistic. If you carefully look at the photo of the spider mite, enlarged many times, you can see its oral apparatus, with the help of which it pierces the plates of plants and sucks the juice.

On a note!

The tick selects fallen leaves as its habitat or hides in the remains of last year's crop. In the cold season, sheltered under foliage, stones, in sheltered soil. With the onset of spring begins to multiply actively.

On tomatoes in a greenhouse and open ground, a tick appears for such reasons:

• planting new seedlings or tomato seeds occurs on the infected site;
• sick tomato seedlings;
• wildflowers infected with the parasite grow nearby.

A spider mite on tomato seedlings appears easily. But to destroy it is sometimes difficult. Particularly favorable conditions for reproduction are created in greenhouses.

Signs of defeat

Since it will not work to see parasites, it can be understood that tomatoes are infected by the following symptoms:

• the presence of white small dots on the leaves at the site of the prokus;
• the lower leaves are curled upwards, subsequently fall off;
• tiny lumps of gray color appear on the back side, reminiscent of dust;
• the appearance of a web that envelops stems, leaves, and even fruits.

On a note!

The web becomes noticeable only with severe damage to the plant.
