Curly Top

Curly top virus causes leaf curling and upward rolling of foliage on many hosts. You notice stunting and yellowing on affected plants. The virus is transmitted by leafhopper insects. Control through insecticide applications and removal of infected plants.

Start with cultural controls: remove infected tissue, improve drainage and air circulation, and keep foliage dry when possible. Curly Top responds best to early intervention, so scout regularly during the growing season and act at the first sign of symptoms. Chemical controls exist for severe cases but work best as preventive treatments before infection takes hold.
