Abstract

•	A meta-analysis of biochar preparation and application methods for disease severity and plant growth is needed.
•	Soil application of biochar from straw at 350–600 °C and at 3–5% rate was effective in reducing disease severity.
•	Biochar application has better suppression effect on cash crop diseases caused by airborne pathogens.
•	The results of the meta-analysis are particularly useful for maximizing the effect of biochar on plant disease control.
