Orchid Pathology:Pseudomonas Infection of Phalaenopsis

- Lebon -

MANILA, Philippines - The microbiologists will look at the devastating Phalaenopsis flower brown spots and tell you it is caused by Pseudomonas (bacterium) infection. 

The entomologist will argue that even if the bacteria are present on the surface of the flowers, it can not enter the flower tissues without an insect biting or puncturing the surface of the flower.

A horticulturist will argue that the infection was caused by too much watering and high humidity in the growing area. 

All three are correct in their analysis but what do we need to do to prevent the same thing from happening again?

Dutch horticulturists always stress that Bacterial Infections in floricultural crops are PRODUCTION SYSTEMS DEFECT

They may be caused by nutritional deficiencies (Calcium, Manganese or Silica deficiencies and high-nitrogen-induced mineral deficiencies), cultural (air-movement defects in greenhouse, incorrect watering gadgets, defective watering techniques, inefficient heat dissipation mechanism, etc.) or Incompetent Management.

A seasoned gardener will tell you that cleanliness (greenhouse surrounding), good aeration (louvers & electric fans help) and prompt attention to problems will keep your plants healthy and spotless.
