How to fight the main pests of lilies

Many growers are faced with the cultivation of lilies with such a problem as pests. Great damage is caused by the larvae of the pearl beetles, potato scoops, bulbous crystal beetles, etc. For pest control using different methods, but the most popular are: soaking bulbs before planting in insecticides or potassium permanganate, prevention during flowering, timely elimination of weeds, dried flowers and leaves.

Lily fly

The lily fly is clearly visible on the lily due to its red color. She lays eggs from April to September. The fly and its larvae feed on the leaves, flowers and seed boxes of lilies, which cause great damage to the plant. Synthetic pyrethroids (Fastek, Karate, Decis, Antizhuk) are used to fight the lily fly. Processing will need to be repeated in two weeks.

Potato scoop

Very dangerous for lilies potato scoop. The caterpillar is red in color, and its eggs are on wild weeds and cereals. It can move on lilies from weeds that grow nearby. The caterpillar eats young shoots from the inside, the flower breaks off and fades. You can fight it by timely weed control.

Onion mite

The tick, the size of which is only 1 mm, causes irreparable harm to lily bulbs. He eats the bulb scales, causing it to rot. The lily leaves turn yellow and die, it stops growing. Gradually, the mite spreads to other bulbs through the soil, and thus all onion plants are infected. You can fight the pest by digging out and destroying the infected bulbs. For prophylaxis, before planting, the bulbs should be held in a solution of potassium permanganate or "Karbofos", sprinkled with chalk.

Important! If your garden plot was infected with a mite, do not grow bulb plants for 3-4 years until it disappears completely.

Aphid and spider mite

Aphid is a very small, but dangerous pest. Aphids on lilies greatly weakens the plant, eating it and infecting with viral infections. You can get rid of it by spraying the lily with insecticides. Spider mites drink the juice from the plants, from which the leaves begin to turn yellow, become covered with spiderweb and dry. Lily can become infected with mite from fruit trees or berry bushes that grow nearby. For the prevention and control of pests, it is necessary to spray not only lilies, but also a number of growing bushes and trees.

Beetle beetle

The most dangerous enemy of lilies is the beetle beetle. But the most dangerous of its larvae. They are very voracious. The beetle and its larvae eat the leaves of lilies and carry various viruses. The pike beetle is resistant to various chemicals, so it is best to destroy it manually. Be careful: if a beetle is dropped, it will pretend to be dead, turning over on its back, and since its belly is black, it is difficult to find it on the ground.

Disease treatment

Lily has a disease, and their treatment depends on timely prevention. Every gardener should know what the lilies and the existing methods of prevention of these diseases are ill with. Before planting bulbs need to carefully inspect for defeat. Be sure to carry out bactericidal treatment at the slightest suspicion of rot. Etch the soil before planting.

How to cure fusarium

Fusarium affects lily roots. If you notice that the tops of the leaves have turned yellow, the base of the stem is rotting, and the plant has begun to dry up - this is fusarium. To combat it should be used lime-fluff or ash. Spray the plants with Topsin-M or Fundazole. If the plants are completely affected, they must be dug up and destroyed.

Bacterial rot

If you notice rust spots on lilies of various sizes, this is most likely bacterial rot. If you do not deal with this disease, the leaves will gradually begin to die off, the buds will fall off, and the lily will dry. To combat rot, use phosphate or potash fertilizers, apply wood ash, process the plant with Bordeaux mixture, Fundazole or Benomil.

Did you know? Many diseases and pests can be transmitted from nearby plants or weeds. For prevention it is worth spraying not only lilies, but also the space around them.

Root rot

Root rot strikes lily bulbs. They are covered with brown spots, the plant begins to grow slowly, and the buds fall. Gradually the lily stem dries out. To combat the disease, carefully select planting material, disinfect the soil with calloid sulfur and treat the bulbs before planting. Damaged plants should be removed and destroyed.

For the prevention of the disease, it is worthwhile to spray the plants and pickle the bulbs with fungicides. The infected plants must be removed from the site and destroyed so that the disease does not spread to healthy lilies.

  • variegation virus - transmitted from tulips. Differs in unusual spotted color of flowers. It can carry aphid;
  • rosette - delayed growth of the flower shoot, deformed stem, crooked and yellowed leaves. The main carrier is aphid;
  • mosaic - spots and stripes on the leaves.
A mosaic lily can bloom and bear seeds. But they will already be infected with a virus. Over time, the lily will die, and the planted seeds will again spread the virus, which can be transferred to other plants by aphids.

In order to avoid infection by viruses of all plants, first of all, one should pay attention to their vectors and take up the fight against insect pests.

Disease prevention

For the prevention of all diseases of lilies, inspect the plants for changing the color of leaves, stems and flowers.
