The most favorite vegetables on the sites of Russian summer residents are potatoes and tomatoes. In the summer, not a single garden remains without these plantings. But if you do not take care of the bushes correctly, you should not count on a good harvest. The main thunderstorm for all vegetable growers is 4 dangerous pests that can destroy standing plants.
The leader among parasites for a long time remains the Colorado potato beetle. Both adult individuals and their larvae feed on leaves of nightshade crops and, unfortunately summer residents, are very gluttonous. They can leave a bare stem from the succulent leaves of potatoes or tomatoes, which will inevitably lead to the drying of the plant.
Over the summer, parasites are able to breed more than one offspring. And if the season turned out to be cool and rainy, the bugs just hibernate, which can last 3 years. In addition, adults easily fly from one crop to another, even if the plantings are located several kilometers from the habitat of the insect.
You can fight the parasite by various methods, but there is no one, the most effective, yet. To guarantee getting rid of the bug, you need to apply several methods at once. Among the most effective are the following:
- obligatory crop rotation;
- planting next to the beds of strong-smelling plants: calendula, onion, wormwood, hemlock;
- picking bugs and larvae with hands;
- spraying the cultures with a solution of tar or a soap composition mixed with ash;
- organization of traps with bait;
- the use of insecticides.
Whitefly, although outwardly elegant and cute, is also capable of harming the plantings. Of all the varieties of this insect, the greenhouse is considered the most dangerous.
The parasite actively multiplies and rapidly populates the lower parts of the leaves. There, he sucks out the juices from the plants and again lays the larvae, which in the same way will kill the plantings.
As a result, the leaves curl and dry, and then completely fall off. In addition, yellow spots form on them. In addition, whitefly leads to the appearance of fungus, gray rot and powdery mildew on plants.
To get rid of whiteflies, summer residents recommend planting a plant with a repelling aroma in the area:
If the infection has not spread too much, you can collect the larvae or treat the bushes with infusion of tar soap or garlic, and a sugar solution is also suitable.
With severe infection, you will have to resort to chemicals. But the insect is able to adapt to toxic substances, so it is best to use a new tool every time.
Aphids can be of different types from potato to peach. You can understand that the culture is affected by the pest by folding the leaves, falling and drying flowers, chlorosis and necrosis, curving the stem and changing the color of leaf veins.
Young leaves are most affected. The aphid settles on their lower side, and then passes on to the fruits and stems. It feeds in the same way as whitefly, therefore, it is able to provoke the same diseases at plantings. In addition, it can infect plants with viruses and attract ants to them.
To protect the plantings from the parasite, it is necessary to collect and burn the stems and weeds remaining after harvesting. It is recommended to plant strongly smelling herbs on the beds. If the pest is wound up, it must be removed by collecting, processing with soapy water, onion husks and cola.
And the 4th dangerous pest on the site is thrips. Detecting them is more difficult due to their small size. Insects hide on the back of flowers and leaves and suck out juices from them, while bringing viruses. The main danger is that the parasite easily moves between the beds through the air.
On the infected leaves, small furrows of white or gray color are formed, which eventually turn into a dry spot. All this leads to the inevitable death of the leaf. As a result, plant growth slows down, yield decreases, and the fruits are deformed.
You need to fight thrips with insecticides. Folk methods will not help here. And it is better to alternate industrial preparations so that the parasite does not have time to adapt to them.
