Narcissus pest control methods

Common daffodil diseases and pests include large brown spot disease, rot disease, nematode disease, daffodil fly, spiny-footed root mites, etc.:

Large brown spot

The disease breaks out around March to May. It is best to spray once every 1-2 weeks using 700 times diluted 75% Benomyl. The bulbs need to be soaked in clean water for about an hour, and then soaked in Gongshui for about 30 minutes before sowing.

Nematode disease

These two symptoms are among the most important diseases of daffodils. After the plant is infected with the disease, the bulb appears intact on the surface, but the inside has already been damaged or rotted. It is necessary to remove the rotten part in time and apply protective agents. The soil needs to be disinfected in time to prevent rot and nematode diseases.

Rhizopus spp

The spiny-legged root mites are shiny white, similar to adult mites, with lighter granules and legs, and white body. They can be sprayed with 1000 times diluted 40% trichlorodicofol.

Narcissus fly

Narcissus flies lay their eggs in the soil, and the hatched larvae invade the bulbs, causing them to rot and turn black. To deal with daffodil flies, you need to use carbon disulfide and water the daffodils during the growing season.
