Abstract The efficacy of the essential oil and various leaf extracts Piper chaba Hunter was evaluated for controlling growth some important phytopathogenic fungi. hydrodistilled analysed by GC–MS. Fifty‐three compounds representing 95.1% total were identified, which α‐humulene (16.4 % ), caryophyllene oxide (12.2 viridiflorol (8.1%), globulol (7.4%), β‐selinene (7.1%), spathulenol (6.2%), ( E )‐nerolidol (5.1%), linalool (4.5%) 3‐pentanol (3.5%) major compounds. (1,000 ppm) organic (1,500 P. displayed a great potential antifungal activity as inhibition against tested fungi, Fusarium oxysporum KACC 41083, Phytophthora capsici 40157, Colletotrichum 410978, solani 41092 Rhizoctonia 40111 in range 55.1–70.3% minimum inhibitory concentration ranging from 125 to 500 μg/ml. had also strong detrimental effect on spore germination all fungi along with well time‐dependent kinetic . results obtained this study may contribute development new agents protect crops fungal diseases.
