Pests and control of lilies

Before you buy a lily for your site, consider each of its bulbs. After all, tempted with a label, you can buy an unhealthy plant. The bulb of the lily should be firm and firm. It should not be moldy. The roots of a healthy specimen are at least five centimeters long. But, in addition to plant diseases, novice lovers lie in wait for pests of lilies. About them, and will be discussed in this article, as well as on how and what to fight with them. Pests of lilies in their number exceed a dozen species. These include greenhouse and lily aphids, thrips, bulbous gushers, fly-fly, bulbous bulbous and other harmful insects.

Pests of lilies: red beetle

The most dangerous and common enemy of the lily is visible on the plant with the naked eye. Going to the flower, you can easily see how it sits on the leaves and eats them. It is called the first when the ailments of lilies (pests) are listed. A red lily bug, it's an onion cracker or a beetle bug. Sometimes people call it a "fireman" - the reason for this is a red color. But the nickname "cracker" he got because of the fact that if you press it, then the insect is able to produce characteristic sounds. Especially dangerous are the gluttonous larvae of this beetle. They have a pink color, and the surface of the trunk is covered with lumps of mucus of a greenish-brown color. 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? Once the larvae were found on the leaves, spray the flowers with an insecticide.

Onion leaf beetle

What other pests can attack lilies? The red lilac beetle in this plan transmits the baton to the onion leaf beetle. This specimen is known for biting leaves at the edges, or creating holes in them having an oval shape. And its larvae completely leave one "skeleton" from the leaves. The adult beetle has an orange color and an oval shape of the trunk. The abdomen is black, and the legs are red. The larvae are covered with mucus, which has a blackish shade. Hibernate these pests of lilies in the soil, come to the surface at the end of April and lay eggs. Hatching larvae live about twenty days, and then pupation occurs. Generally one generation is formed.

The pests of lilies and the fight against them, although similar, but have some differences. In this case, in addition to treating plants with insecticides, it is necessary to regularly destroy weeds and collect beetles manually.

Aphid

This pest is very small and forms whole colonies on the leaves. It greatly weakens the plant, and also carries a large number of viral infections. To ensure that your garden has grown and blossomed a beautiful and healthy lily, pests (beetles, aphids and others) must be ruthlessly destroyed. In particular, aphids can be defeated with the help of "Carbophos", "Phytopharma" 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, resulting in the decay of the latter. Lily, infected with a tick, stops its growth. Its leaves become yellow and gradually fade. The weakened plant is exposed to various other diseases and eventually dies. The spread of the tick occurs through the soil together with the material for planting or through a tool for tillage.

Before processing lilies from pests, it is necessary to establish which of them affected the plant. When examining bulbs afflicted with a tick, you can find a lot of moves and cavities in which brown powder is located. Such bulbs should be removed after digging. All plant residues are collected carefully and destroyed. If the planting material is suspected of the presence of this pest, then all bulbs must be held in a solution of "Carbophos" for fifteen minutes or pour them with chalk. Sticking to the body of the mites, chalk leads them to death from withers. If the pest was detected in the growing season, then you should sprinkle the lily with the solution of the horn, but it is better to destroy all the sick specimens. If your site was infected, then it is impossible to grow bulbous plants on it for four years.

Pests of a lily. Flies

Large damage to the bulbs is caused by the larvae of flies-murmurs, which received their name for the ability to freeze in flight, while producing a characteristic sound. In bulbs, they eat up and down. From May to June, these lily pests lay their eggs in the soil. Here there are gluttonous larvae, which survive the winter in the bulbs of plants. As a result of this "settlement" in the spring, a weakened lily grows. The leaves of this flower are ugly and have a yellow color.

Fighting them is to dig up the soil in the fall. And it needs to be done deep enough, wrapping the layer. Prevent the laying of eggs can be, mulching the ground with peat or dusting "Bazudin". Garlic will also come to the rescue, which should simply be planted around the perimeter of the bed.

Medvedko

We have already examined many pests of lilies and the fight against them. But in this list you can not bypass the ordinary bear. This insect is large in size, has a brown color. Medvedka arranges the nests in the soil at a depth of about 10 cm. In order to better ventilate, this pest destroys all the plants around it, gnawing the underground part of the stem. On the site where the bear lives, you can find a huge number of holes in the soil. It is especially good to see them after the rain.

You can fight this insect in several ways. The first is the destruction of the nests. They are simply unearthed, and the larvae and eggs are thrown upward, where they perish. To be sure to destroy all nests, you need to dig a site deep enough. Another method is to arrange traps. In the spring on the beds lay slate or plywood sheets. Under them, the bear is taken to get warm. It remains only to check the traps with a certain periodicity and destroy the pest. And one more way - the creation of manure pits in the fall. Grooves half a meter thick filled with manure, into which the bear takes refuge for the winter. As soon as cold comes, the pits are cleaned and the contents are distributed over the site. As a result, insects perish.

Nematodes

These are small round worms. They live in the ground, and the development of individuals occurs inside the plant. Due to their vital activity on the leaves and stems, growths and tumors are formed. Suspected the presence of this parasite can be seen by cracking the trunk or deformed flowers. In addition, nematodes are able to tolerate various viral diseases.

The fight against these worms is to disinfect the soil, as well as to exterminate the affected plants.

Potato scoop

Such lily pests, like a scoop, eat out the trunks of plants from the inside. As a result of such damage, the flower breaks down or fades. The caterpillar has a reddish-lilac color and a bright red line stretching along the back. Eggs of these caterpillars spend all winter time on wild grasses, and in summer they move 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 the scoop on the lilies, you need to thoroughly clean your area of weeds, as well as all sorts of plant debris. All this must be collected and destroyed.

Thrips

In some cases, small insects with an elongated shape parasitize the root system of the lilies. They are called thrips. Their mouth organs look like a proboscis. These pests prick the plant tissue and suck the juice out of it. The plant after this strongly weakens, and its appearance loses its attractiveness. But the most dangerous is the transfer of thrips of various viral diseases. For a 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 longer life cycle.

It is possible to fight these insects with any insecticide of a systemic kind. It can be, for example, "Carbophos" or "Phyto-verm". 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 in garden plots. But this does not mean that our list is exhausted. In addition to the insects examined, 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 carry out preventive and curative measures on time. Then your daylily will look wonderful and make your eyes bright and healthy colors.
