Every housewife dreams of having a beautiful and fragrant flower garden on her garden plot. But, unfortunately, this dream does not always come true. Garden flowers, like other plants, are often attacked by various pests, which cause incredible damage to them, and sometimes even lead to death. Many insects, worms, slugs and rodents feed on plant tissues, which greatly dulls their growth, as a result, they do not develop and practically do not bloom
Often, pests are carriers of the most dangerous diseases that can cause a whole epidemic in the garden. For this reason, the prevention and control of pests is one of the most important measures for the care of flower crops. To date, a number of effective and rational methods of pest control have been developed, the use of which makes it possible to avoid the death of plants, even in the most advanced cases.
Pests of gladioli
The most malicious pests of gladioli are thrips. They usually appear under unfavorable growing conditions, especially in hot and dry weather. Thrips affect the corms, as well as the leaves and flowers of gladioli, which are subsequently greatly deformed. As a preventive measure, plants are treated with Karbofos (80 g per 10 l of water). Corms are kept in a solution of the drug "Agravertin" (10 ml per 1 liter of water) or an infusion of garlic (2 tablespoons garlic pulp per 1 liter of water).
Caterpillars of leaf-eating scoops are frequent guests in flower beds with gladioli. They feed on the leaves and buds of plants, eating round or oblong holes. In the fight against them, the most effective drug "Iskra" (2 tablets per 10 liters of water).
Wireworms are also dangerous for gladioli, the larvae of which gnaw out the underground part of the stem and corms. When the first signs are found, the plants are treated with the drug "Bazudin" (10 g per 1 sq.m.).
Rose pests
Quite often, roses are affected by aphids (leafy rose and green rose). Pests settle in huge numbers on the leaves of plants, gradually move to the stems, and then to the buds, sucking the juice from the tissues. The affected parts of the plants become whitish and ugly, the roses are lacking in nutrition. Aphids appear with prolonged drought or an excess of nitrogen fertilizers in the soil.
The pest multiplies very quickly, it is difficult to imagine, but in the open field it can give several tens of generations. To combat aphids, it is recommended to use the preparations "Iskra", "Confidor" or "Karbofos". Spraying is carried out every 10-12 days. Infusions of nettle, wormwood and dandelion are no less effective. By the way, nettle infusion can be used as a prophylactic agent, as it strengthens the outer tissues of roses and increases their resistance.
In hot and dry weather, roses are affected by a spider mite, which settles on the inside of the leaves and sucks the juices from the tissues, as a result, the leaves dry out and fall off. If pests are found, the plants are treated with solutions of the preparations "Karbofos" (60 g per 10 liters of water), "Agravertin" (1 ampoule per 1 liter of water) and "Colloidal sulfur" (40 g per 10 liters of water).
Often, roses are attacked by rosaceous leaf rollers, the caterpillars of which heavily eat up the leaves, sometimes to such an extent that bare stems remain. Fossbecid (5 ml per 5 l of water) and Iskra (10 g per 10 l of water) are effective in the fight against rose leaf rollers.
Wireworms are not safe for roses. Their larvae eat the stems and roots of plants. As a rule, pests appear when there is an excess of moisture; in early spring, when the snow melts, they collect in large numbers in the upper layer of the soil. The preparation "Bazudin" (15-20 g per 10 sq.m.) is excellent for combating wireworm larvae.
Aster pests
Among the pests of asters, the common earwig is the most common. The body of the pest is pitch-brown, up to 2 cm long. Adult insects inflict damage to plants, starting from the second decade of June until the very frost. Earwigs damage buds, inflorescences and leaves of asters. They fight against them by pollination of the culture with pyrethrum and foundation, as well as manual collection.
Aster blizzard, or sunflower moth, is a small butterfly, gray or light gray caterpillars of which feed on flower petals and aster pollen, and later damage the achenes located in flower baskets. Pest prevention involves growing asters away from sunflowers (at a distance of at least 300-500 m), pre-sowing treatment of the soil with basudin and the destruction of weeds of the Asteraceae family.
A slobbering penny will also not benefit the asters. Yellowish-green larvae settle in the axils of leaves and shoots, emitting foamy substances, damage leaves and stems, which are subsequently deformed. This usually leads to the appearance of yellow spots on the leaves and a decrease in the abundance of flowering. To combat the penny, use drugs "Karbofos" or "Antio", a decoction or infusion of tobacco with soap.

Fruit Pest Is An Unusual Pest
Fruit shellfish, which lives almost everywhere, attacks literally all fruit crops. However, you can also see it on the oak tree.

Black Goldfish - A Pest Of Fruit Crops
Black goldfish is a harmful inhabitant of the steppe regions. It can often be seen in some forest-steppe regions. This villain seriously harms such fruit crops as apricots, cherries, peaches, thorns, cherries, plums and almonds. She will not refuse to feast on a pear with a hawthorn. The larvae are mainly harmful - if they get to the tree roots and to the cambium, the tree attacked by them can quickly die. Black goldsmiths are especially dangerous in young gardens and nurseries
Rapeseed Beetle - A Pest Of Cabbage Crops
The rape flower beetle, which lives almost everywhere, willingly feasts on the seed plants of oilseeds and cabbage vegetable crops. Sometimes it can be found on beet plantings, on flowers of legumes, as well as on fruit plants and a number of other crops. The gluttonous larvae of the rape flower beetle, eating the contents of the buds, are especially harmful. As a result of their attacks, the buds die off rather quickly, which in turn cannot but affect the volume of the crop and its quality
