seedling death on Date Palm
Quick answer
If your Date Palm has seedling death, the most likely cause is: Chaetomium globosum produces lytic enzymes and mycotoxins (chaetomin, xanthenone, chaetoglobins) that suppress Rhizoctonia solani, Fusarium oxysporum, F. chlamydosporum, and F. solani. The fungus also increases phenol, indol acetic acid, and polyphenol oxidase activity in treated plants.
Start here:
- 1. 1. Prepare inoculum: culture C. globosum on sterilized sorghum grain medium at 27°C for 2 weeks
- 2. 2. Mix into peat moss clay soil (1:1) at 3% (w/w) rate
