The infection is very resistant, it does not die on fallen inflorescences, foliage. To prevent pansies from catching this disease, you need to spray the plant with sulfur or preparations Skor, Ordan, Horus. They should be used clearly according to the instructions. All plant remains are destroyed so that the infection does not spread to other beds.

Reasons for the appearance of gray rot

High humidity often causes viola to rot. This is due to heavy rains, more often in the second half of the summer period. The plant is covered with a bloom of gray, the stem becomes soft to the touch, "liquidish". If the pansies are sick with gray mold, the plants will have to be destroyed.

Gall nematode

The nematoda settles on the roots of the viola. Because of this, galls are formed on the rhizome - growths, swellings about 6 mm in size. In these "balls" the larvae of the parasite develop. When they get out of the ground, they begin to actively gnaw the plant. This problem leads to early wilting of viola in the open field. To remove nematodes, you need to steam the ground before planting the viola. Pests cannot withstand temperatures above 50 degrees. Also, good results are obtained by introducing sodium nitrate. You need to do this about a week before planting the plants in the ground. Consumption is 150 g per square meter.

Spider mites are the cause of leaf curling in viola seedlings.

The caterpillars have a distinctive white stripe on the black back; these are the larvae of an ordinary mother-of-pearl. The caterpillars of the large forest nacre have a different color. It has a huge yellow stripe and brown dashes on the sides. These insects eat both flowers and leaves. As soon as the mother-of-pearl appears on the pansies, an urgent need to apply insecticides. They cope well with the pest Kinmix, Iskra-Bio, as well as Tsitkor.

Aphid

These ubiquitous parasites are very small green insects. They settle primarily on beautiful viola flowers, infect the petals and buds of the plant. Aphids draw out all the juices from the flower, it begins to wither, the petals are greatly deformed. If the aphid colony on the plant is significant, then the culture is covered with drops of white sticky liquid. You can notice them on the leaves and near the peduncles. To get rid of insects, you need to pickle plants with Aktelik or Mospilan.
