When Lycoris has diseases and pests, this method of prevention and control is more effective!

Common diseases: Soft rot

During the disease period, the plant may turn brown and slowly become soft and rotten, and in severe cases, the entire plant may die.

Prevention and control methods: Soak the bulbs to be planted in copper sulfate solution for half an hour, take them out, rinse them with clean water, and then plant them after they are naturally dried. Spray with carbendazim once every half a month. If it is the early stage of the disease, you can spray it with benomyl.

Common pests: Spodoptera litura

The pest is most likely to occur from early summer to late November. It chews on plants.

Prevention and control methods: You can spray with pesticides such as Wanling.

Common insect pests: Lycoris radiata

This larva is very annoying. It will burrow into the inside of the plant and eat away all the inner tissue of the plant, and it can also survive inside the plant. The leaves of the plant are the worst affected.

Prevention and control methods: Loosen the soil and remove the underground pupae. Spray the plants with chlorpyrifos emulsifiable concentrate or chlorpyrifos. The best time to sandblast is early in the morning or evening, when pests are active. At the same time, if you find signs of activity of this pest on the plant, you can directly remove the affected leaves.

Common pests: Thrips

Prevention and control methods: Imidacloprid and Aimele can be used interchangeably for spraying on the plant surface.

Common pests: white grubs

The biggest feature of this pest is that it can live permanently in the soil and particularly likes to eat seeds and seedlings.

Prevention and control methods: If this pest is found, it can be directly sprayed with trichlorfon, phoxim or other insecticides.
