The effect of amount of water used to irrigate casing soil on the development of bacterial diseases of the white button mushrooms

The most common bacterial diseases of mushrooms are the brown blotch caused by Pseudomonas tolaasii and ginger ‘gingeri’. Protection against infections consists in ensuring an appropriate microclimate cultivation rooms. aim study was to assess severity symptoms depending on amount irrigating water mushroom cultivation. crop infected with a suspension cells as equivalent application 2.6 × 107 108 per 1 m2 casing surface. watered fixed amount, i.e. 7, 10 14 litres before first flush 6, 8 second flush. It found that had significant impact blotch, especially yield significantly higher highest than other variants experiment. In case P. statistically insignificant observed water. disease used irrigate soil were highly or moderately correlated each. has been shown properly conducted watering treatment reduces development blotches mushrooms.
