Pests are insects that damage plants. Flower plants of open ground are harmed by scutes, moths, leaf rollers, thrips, aphids, scoops, nematodes. And also cabbage and onion flies, bedbugs, mites, leaf fleas and so on. Their "activity" pests begin in nurseries.
Pests of plants
Thrips
These small insects are difficult to consider. But with mass reproduction, they can inflict enormous damage on crops. Basically they feed on plant juice. In hot weather, through punctures, pests left on the tissues of plants evaporate a lot of moisture and develop various diseases.
Fighting Thrips
In autumn, plant residues must be destroyed at the site by burning. The site is deeply digged, so you can destroy the larvae and adults that winter in the upper layers of the soil. If the site is heavily infected, then it is necessary to re-plant ornamental plants 4 years later. Garlic and tomatoes planted with gladioli can scare off pests.
Medvedka
This large insect, 6 cm long, has a dark, brown color, rarely appears on the surface. It damages roots, root crops, seeded seeds and bulbs.
To combat the bear, dig holes in infected areas with a depth of 60 cm. The walls and the bottom of the pit are covered with a film and the heated manure falls over these holes. In such pits of the bear and hide for the winter. When frosts come, the manure from the pits must be thrown away and the pests perish. In the spring, dig deep in the soil, in summer to loosen it, it can prevent the pest from extracting food.
Stemplate
It affects decorative bushes and lilacs. Scutellum in the female comma-shaped - elongated, up to 3 cm long. The female lays eggs in groups. The larvae creep along the plant and suck in to the bark of the trunk, branches, shoots.
Fighting with a shield
To destroy the scabbard you need to take a packet of "Aktary" dilute in one liter of water and this water 3 times to pour sick plants. Within a week the scabbard will die.
Sick plants need to be isolated on a separate window sill, place the location of the pots with a soap solution, then with an insecticide solution. All the plants should be washed with tobacco infusion or a soapy solution to wash off the scabbards. When the leaves evaporate water, sprinkle the plant with insecticide solution, cover with a plastic bag for 40 minutes. Then remove the package and after 2 days the plant is washed under the shower to wash off the dead insects and wash off the insecticide. Procedures are carried out weekly until the complete destruction of the scabbard.
Naked Slugs
There are slugs - mesh and plow. The color of the plow is lightly yellow-gray in color. The body is long to 5 cm. The mesh has a brownish or gray color, the body is fusiform, up to 7 cm long. Slimes are active in the daytime, in cloudy weather, at night and at dusk.
Fight against slugs
On the site you need to destroy the weeds. In the evening, pollinate plants slaked lime. After 15 minutes, pollinating is repeated. In the fall, dig deeply into the plot. Wintering slugs and eggs fall deep into the soil and die there.
The worm and larvae of the May beetle are also referred to as pests. They damage the root system of young ornamental plants. Fighting them is difficult, you have to pick the soil, free the site from the plants and put them back in place. Often a plot may be infected by a wireworm if earlier potatoes were planted here. Therefore, ornamental plants should be planted in areas that are free from root pests.
Of preventive measures, great importance is the autumn plowing of the soil. Approximately 75% of flower crops hibernate on the soil surface, sheltering from cold weather among the dead parts of plants and under fallen leaves. Every year you need to dig the soil under the plains, all affected plants and plant residues must be burned, it is unacceptable to lay them in compost piles.
Conduct fighter measures to destroy pests, both in closed and open ground: spraying plants with poisons of internal and external action, dusting, disinfestation of greenhouses, greenhouses, empty greenhouses.
