Fruit(s) |
Lemon completely covered with sporulation by Penicillium digitatum. May 1994 |
| 1570809 |
Fruit(s) |
Green mold of lemon 5 to 7 days following inoculation and storage at 15C. Note the different zones of disease progress: sporulation at center and advancing mycelium. Little to no watersoaked host tissue in contrast to blue mold. May 1994 |

Fruit(s) |
Green mold of lemon prior to sporulation. May 1994 |

Fruit(s) |
Decayed lemon after harvesting spores. June 1994 |

Fruit(s) |
Imazalil-sensitive Penicillium digitatum on imazalil-treated lemon. Note the sporulating area. This was isolated and found to be imazalil-resistant. Was this the result of a mutation or a contaminant? May 1994 |

Fruit(s) |
Green mold of lemon showing soiling of adjacent fruit and what appears to be spread by contact (nesting). Note also the presence of whisker mold (Penicillium ulaiense) March 1994 |

Fruit(s) |
In planta bioassay for fungicide resistance in Penicillium digitatum. Fruit were dipped for 30 seconds in solutions containing 4000, 6000 and 8000 ppm imazalil, injected with a spore suspension of P. digitatum and incubated at 25oC for 7 days. Results show that the imazalil-resistant isolate will decay and sporulate on treated fruit. October 1990 |

Fruit(s) |
In planta bioassay for fungicide resistance in Penicillium digitatum. Fruit were dipped for 30 seconds in a solution containing 1000 ppm imazalil, injected with a spore suspension of P. digitatum and incubated at 25oC for 7 days. Results show that the imazalil-resistant isolate will decay and sporulate on treated fruit (right) while the sensitive isolate will decay, but not sporulate on treated fruit (left). An excellent example of sporulation inhibition by a triazole fungicide. March 1991 |
