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 |

The relationship of inoculum density to growth of Penicillium digitatum on fungicide-amended medium. A range of spore concentrations (0.4, 0.8, 1.6, 3.2 6.3 and 12.6 x 106spores/ml) were spread over the surface of potato dextrose agar amended with 0.3, 0.5 and 0.7 ppm imazalil. Results show that very large fluctuations in inoculum concentration are needed in order to have a measureable effect on growth. August 1991 |

Lemons (treated with a mixture of 4000 ppm imazalil + 5000 ppm thiabendazole and 2000 ppm imazalil and non-treated) inoculated with Penicillium digitatum (imazalil-resistant isolate) show the typical reaction. Decay and sporulation on treated fruit is similar to non-treated fruit. August 1990 |

Penicillium digitatum |
In planta biological assay for fungicide resistance. Lemons (treated with a mixture of 4000 ppm imazalil + 5000 ppm thiabendazole and 2000 ppm imazalil and non-treated) inoculated with Penicillium digitatum (imazalil-sensitive isolate) show the typical reaction. Decay and sporulation on treated fruit is greatly reduced compared to non-treated fruit. August 1990 |

Lemons (treated with a mixture of 4000 ppm imazalil + 5000 ppm thiabendazole and 2000 ppm imazalil and non-treated) inoculated with Penicillium digitatum (imazalil- and thiabendazole-resistant isolate) show the typical reaction. Decay and sporulation on treated fruit is virtually identical to that on non-treated fruit. October 1990 |

Penicillium digitatum |
A colorless mutant of Penicillium digitatum (isolate J-56W) compared to the normal phenotype (isolate J-15) on imazalil-treated and untreated lemons. |

green mold |
Penicillium digitatum |
A colorless mutant of Penicillium digitatum (isolate J-56W) compared to the normal phenotype (isolate J-56) on lemon. Arrows indicate point of inoculation. Results show that the mutation to colorless is stable and that the growth rates of both isolates are similar in lemon. September 1991 |

green mold |
Penicillium digitatum |
A colorless mutant of Penicillium digitatum (isolate J-56W) compared to the normal phenotype (isolate J-56) on lemon. Left: isolates were inoculated into lemon from opposite sides. Right: a mixture of the same isolates was inoculated into lemon. Results show that the mutation to colorless is stable and that the growth rates of both isolates are similar in lemon. September 1991 |

green mold |
Penicillium digitatum |
A colorless mutant of Penicillium digitatum (isolate J-56W) resistant to imazalil compared to a wild type phenotype (isolate YUMA) on imazalil-treated lemon. Arrows indicate the point of inoculation. Results show that the mutation to colorless is stable and that growth and sporulation on imazalil-treated lemons is similar to the normal/colored phenotype. September 1991 |

green mold |
Penicillium digitatum |
Culture of a single isolate of Penicillium digitatum after seeding onto two replicate plates of imazalil-amended medium. The results should be identical, but they are quite opposite due to sectoring of the isolate. This result was highly unusual. February 1992 |
