Symptoms Symptoms of mosaicism on the leaves occur while producing stripes.

The pathogenic Turnip Mosaic Virus (TuMV) virus is linear in size, ranging in size from 700 to 80012 to 18 nanometers, with a toxic temperature of 55 to 66°C, an end point of dilution of 2000 to 5000 times, and an in vitro period of 24 to 96 hours. In nature, the virus is spread by contact with aphids or sap.

Transmission routes Viruses can be transmitted through the aphids and sap to make disease-free healthy strains.

Turnip mosaic virus can be infected by aphids and sap, but the field is mainly aphid infection. Seeds can not be transmitted virus, pollen can not be infected with the pollen of the diseased plants, and the maggots are non-persistent. After the maggots have been sucked on the diseased plants for a few minutes, the virus in the diseased strains is adsorbed in the mouthparts, and the worms smoke again. In the case of a healthy strain, the virus attached to the locust mouthpart is directly injected into the plant during the sucking process. The most commonly transmitted locust is Myzus persicae.

Control methods Aphids are mediators of transmission and should be controlled in time.
