Diseasemoderate

Symptoms: concentric rings of reddish-brown pustules on leaf undersides; yellow spots on the upper surface; stems and flower spikes stunted; severely rusted plants wilt before flowering

  • CulturalRemove infected plants and keep foliage drystrong evidence — extension confidence

    Pull and bag badly infected plants. The rust needs leaves wet for 6-8 hours to infect, so water early at the base, space plants, and avoid overhead watering.

  • CulturalChoose resistant varieties and start cleanmoderate evidence — extension confidence

    Plant rust-resistant snapdragon series where available and start from disease-free plants; resistance can break down over time, so cultural steps still matter.
