Khamis Youssef; Sergio Ruffo Roberto Horticulturae 2020. doi:10.3390/horticulturae6020031
Other claims from this paper (10)
- Association Alternaria alternata, Cladosporium cladosporioides, Fusarium semitectum and Penicillium spp. were associated with apple fruit drop.
- Observation A. alternata was the most frequently isolated fungus from dropped apple fruit.
- Intervention effect In pathogenicity tests the maximum apple fruit drop occurred when petioles and fruits were inoculated with mixed fungal pathogens on branch sections with fruit.
- Intervention effect In vitro, all four fungicides completely inhibited the growth of A. alternata, C. cladosporioides and F. semitectum at 400 mg per L.
- Intervention effect Under natural infection, thiophanate methyl applied at fruit set had the greatest effect against premature apple fruit drop (81.68%).
- Intervention effect Under natural infection, difenoconazole reduced premature apple fruit drop by 73.76%, second after thiophanate methyl.
- Intervention effect Under natural infection, pyraclostrobin + boscalid reduced premature apple fruit drop by 70.29%.
- Intervention effect Under natural infection, carbendazim reduced premature apple fruit drop by 66.34%.
- Mechanism The authors suggest that premature apple fruit drop may in part result from diseases caused by certain phytopathogenic fungi.
- Recommendation The authors conclude the fungi could be controlled with fungicides applied at the beginning of fruit set.
