What are the control methods for tulip black rot?
Symptoms: The bulb becomes diseased. On the stem plate and stem surface, and sometimes on the 2nd and 3rd scales, irregular lesions first appear yellowish-brown and later dark brown, with a rough surface. The pathogen is Pseudomonas andropogonis (Smith) Stapp, a Pseudomonas bacterium. The bacterial cells are rod-shaped, 1.9*0.8 micrometers in size, with 1 to 3 polar flagella. The optimum temperature for disease development is 20-25°C, with a minimum of 5°C. Transmission route: infected bulbs and diseased plant residues in the soil are the sources of infection. Control methods: try
