- Observation Alternaria alternata, Alternaria tenuissima and Colletotrichum gloeosporioides were isolated from symptomatic cactus pear cladodes.
- Observation Aspergillus tubingensis was isolated from symptomatic cactus pear cladodes.
- Association Alternaria alternata was the most aggressive of the isolated pathogens and was selected for antagonism assays.
- Association Bacterial isolates B. siamensis, B. halotolerans and P. peli, and Trichoderma harzianum, showed the highest antagonist efficacy.
- Observation The efficacy of the three most effective bacterial isolates was confirmed in vivo on one-year-old cladodes.
- Observation Trichoderma harzianum showed significant pathogenic potential on cladodes of O. ficus-indica and O. megacantha.
- Observation The three most effective bacterial isolates produced antifungal volatile organic compounds.
- Observation Amylase, chitinase and cellulase production differed among the three most effective isolates.
- Observation Protease production differed among the three most effective isolates.
- Observation Genes associated with antifungal lipopeptide biosynthesis were detected only in P. peli.
