Before you buy a lily for your site, consider each of its bulbs. After all, being tempted by the label, you can buy an unhe althy plant. The lily bulb should be resilient and hard enough. It shouldn't have mold. The roots of a he althy specimen are at least five centimeters long. But, in addition to plant diseases, lily pests also lie in wait for novice lovers. They will be discussed in this article, as well as how and with what to fight them. Lily pests exceed a dozen species in their numbers. These include greenhouse and lily aphids, thrips, bulbous rattlesnake, hoverfly, bulbous leaf beetle and other harmful insects.
Lily pests: red beetle
The most dangerous and widespread enemy of the lily is visible on the plant to the naked eye. Approaching the flower, you can easily see how it sits on the leaves and eats them.
He is called first when lily diseases (pests) are listed. Red lily beetle, aka bulbous rattle or peep beetle. Sometimes people call him a "fireman" - the red color is to blame. But he got the nickname "ratchet" due to the fact that if you press it, the insect is able to make characteristic sounds. special dangerrepresent the voracious larvae of this beetle. They have a pink color, and the surface of the body is covered with lumps of green-brown mucus. Such pests of lilies (red beetle and its larvae) eat leaves almost completely.
If enemies were found, then the question arises - how to treat lilies from pests? As soon as the larvae were found on the leaves, the flowers should be sprayed with an insecticide.
Onion leaf beetle
What other pests can attack lilies? The red lily beetle in this regard passes the baton to the onion leaf beetle. This specimen is known for nibbling leaves around the edges, or creating oval-shaped holes in them. And its larvae completely leave one “skeleton” from the leaves. The adult beetle is orange in color and has an oval body. Its belly is black and its legs are red. The larvae are covered with slime, which has a blackish tint. These pests of lilies overwinter in the soil, come to the surface at the end of April and lay their eggs. The hatched larvae live for about twenty days, and then pupation occurs. In general, one generation is formed.
Lily pests and their control, although similar, have certain differences. In this case, in addition to treating plants with insecticides, it is necessary to regularly destroy weeds and collect beetles by hand.
Aphid
This pest is very small and forms entire colonies on the leaves. It greatly weakens the plant, and also carries a large number of infections of viral origin.
To grow on your site anda beautiful and he althy lily has blossomed, pests (beetles, aphids and others) must be mercilessly destroyed. In particular, aphids can be defeated with Karbofos, Fitoverm and other insecticides.
Onion root mite
This pest damages a lot of bulbous plants. Its length is not even one millimeter. The tick feeds on the scales of the bulb, causing the latter to rot.
A lily affected by a tick stops growing. Its leaves turn yellow and gradually wither. A weakened plant is exposed to various other diseases and eventually dies. The spread of the mite occurs through the soil along with the planting material or through the tillage tool.
Before treating lilies from pests, it is necessary to establish which of them struck the plant. When examining bulbs affected by a tick, one can find many passages and cavities in which a brown powder is located. Such bulbs should be removed after digging. All plant residues are carefully collected and destroyed. If the presence of this pest is suspected in the planting material, then all the bulbs must be kept in the Karbofos solution for fifteen minutes or sprinkled with chalk. Chalk adhering to the body of ticks leads them to death from desiccation. If the pest was detected during the growing season, then the lilies should be sprayed with a solution of Rogor, but it is better to destroy all diseased specimens. If aIf your plot has been infested, bulbous plants cannot be grown on it for four years.
Lily pests. Flies
Great damage to the bulbs is caused by the larvae of hover flies, which got their name for the ability to freeze in flight, while making a characteristic sound. In the bulbs, they eat through the passages up and down. From May to June, these lily pests lay their eggs in the soil. Here the voracious larvae appear, which wait out the winter in the bulbs of plants. As a result of this “settlement”, a weakened lily grows in the spring. The leaves of such a flower are ugly and have a yellow color.
The fight against them is to dig up the soil in the fall. And you need to do this deep enough, wrapping the layer. You can prevent egg laying by mulching the ground with peat or dusting it with Bazudin. Garlic will also come to the rescue, which should simply be planted around the perimeter of the garden.
Medvedka
We have already considered many pests of lilies and their control. But in this list you can not get around the common bear. This insect is large in size and has a brown color.
Medvedka equips nests in the soil at a depth of about 10 cm. To better ventilate them, this pest destroys all plants around, gnawing the underground part of the stem. In the area where the bear lives, you can find a huge number of holes in the soil. They are especially visible after rain.
There are several ways to fight this insect. The first is the destruction of nests. Their justdug up, and the larvae and eggs are thrown upstairs, where they die. To be sure to destroy all the nests, you need to dig the site deep enough.
Another method is to set traps. In the spring, sheets of slate or plywood are laid out on the beds. Under them, the bear climbs to warm up. It remains only to check the traps at regular intervals and exterminate the pest. And another way is to create manure pits in the fall. Recesses of half a meter are filled with manure, in which the bear settles for the winter. As soon as the cold sets in, the pits are cleaned and the contents are distributed over the site. As a result, the insects die.
Nematodes
These are small round worms. They live in the ground, and the development of individuals occurs inside the plant.
As a result of their vital activity, outgrowths and tumors form on the leaves and stems. You can suspect the presence of this parasite by seeing cracks on the trunk or deformed flowers. In addition, nematodes are capable of carrying various viral diseases.
The fight against these worms is to disinfect the soil, as well as to exterminate the affected plants.
Potato Scoop
Lily pests like scoops eat away plant stems from the inside. As a result of such damage, the flower breaks or fades. The caterpillar has a reddish-purple color and a bright red line stretching along the back. The eggs of these caterpillars spend all winter time on wild cereals, and in summermove to flowers and other cultivated plants. Pupation occurs in the soil next to damaged plants at a depth of five to fifteen centimeters.
To prevent the invasion of scoops on lilies, you must carefully clean your site from weeds, as well as from all kinds of plant residues. All this must be collected and destroyed.
Thrips
In some cases, small elongated insects parasitize the root system of lilies. They are called thrips. Their mouthparts look like a proboscis.
These pests pierce the tissues of the plant and suck out the juice from it. The plant then weakens greatly, and its appearance loses its attractiveness. But the most dangerous is the transmission of various viral diseases by thrips. During the year, these parasites can form from three to eight generations. All this depends on the type of pest, as well as on the temperature and humidity of the environment. The number of generations becomes significantly less if the ambient temperature drops. This is primarily due to the increase in the duration of the life cycle.
You can fight these insects with any systemic insecticide. It can be, for example, Karbofos or Fitoverm. Begin to process plants with the advent of spring. Further processing is carried out every ten or twelve days.
All pests of lilies, photos and descriptions of which are presented in this article, are the most common and often found ongarden plots. But this does not mean that our list is exhausted. In addition to the considered insects, there are others that infect these plants less often, and also carry various diseases of viral and non-viral origin. But this is not a reason to despair and refuse such beautiful flowers on your site. The main thing is to study the available information and take preventive and therapeutic measures in time. Then your daylily will look wonderful and delight your eyes with bright and he althy colors.
