    Three New Species of B Otryotinia on Ranunculaceae1

    THREE NEW SPECIES OF B OTRYOTINIA ON RANUNCULACEAE1 G. L. HENNEBERT2 Institut agronomique, Universite de Louvain, Hervelee, Belgium AND J. W. GROVES3 Research Branch, Department of Agriculture, Ottawa, Canada Received October 10, 1962 Abstract Three new species of Botryotinia on Caltha palustris L., Ranunculus septen- trionalis Poir., and Ficaria verna Huds. (Ranunculaceae) are described as B. calthae Hennebert and Elliott, B. ranunculi Hennebert and Groves, and B. ficariarum Hennebert. Each of the three species has a Botrytis state of the 73. cinerea complex, and they thus constitute additions to the species already segregated from that complex, i.e. Botryotinia fuckeliana, 73. convoluta, B. draytoni, and B. pelargonii. The Botrytis state of B. ficariarum can be distinguished morp­ hologically. While B. ranunculi is a North American species and B. ficariarum an European one, B. calthae is reported from both continents. Introduction Botryotinia, a genus of the Sclerotiniaceae, was erected by Whetzel (1945) for four species formerly assigned to Sclerotinia Fuckel, but which differ from the true Sclerotinia species mainly in their erumpent, planoconvexoid sclerotia which are firmly attached to the substrate, and in the possession of a conidial state belonging to the form-genus Botrytis Pers. The type species is Botryotinia convoluta (Drayton) Whetzel in which the conidial state is a Botrytis of the cinerea type or B. cinerea sensu lato, and the other species included were Botryotinia fuckeliana (De Bary) Whetzel, of which the conidial state is Botrytis cinerea Pers. or B. cinerea sensu stricto, and Botryotinia ricini (Godfrey) Whetz. and B. porri (v. Beyma) Whetz. In the latter two species the conidial states would not be considered Botrytis species of the cinerea type.

Evolutionary ecological hypotheses of the recovered taxa and Species Hypotheses are difficult to test due to problems with alignments and the lack of a phylogenetic backbone. We propose an updated phylum- and class-level fungal classification accounting for monophyly and divergence time so that the main taxonomic ranks are more informative. Based on phylogenies and divergence time estimates, we adopt phylum rank to Aphelidiomycota, Basidiobolomycota, Calcarisporiellomycota, Glomeromycota, Entomoph- thoromycota, Entorrhizomycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota and Olpidiomycota. We accept nine subkingdoms to accommodate these 18 phyla. We consider the kingdom Nucleariae (phyla Nuclearida and Fonticulida) as a sister group to the Fungi. We also introduce a perl script and a newick-formatted classification backbone for assigning Species Hypotheses into a hierarchical taxonomic framework, using this or any other classification system.

Strawberry production, however, is often threatened by pathogens. One of the most destructive fungal pathogens is Botrytis cinerea, the causal agent of gray mold disease. The control of gray mold in commercial fields is largely dependent on the application of fungicides, including the dicarboximide iprodione and the hydroxyanilide fenhexamid. Because both fungicides are prone to resistance development, a survey was conducted to determine the occurrence and prevalence of fungicide resistance.

Abstract: Botrytis cinerea is a destructive necrotrophic pathogen that can infect many plant species. The control of gray mold mainly relies on the application of fungicides, and the fungicide fludioxonil is widely used in China. However, the field fungicide resistance of B. cinerea to this compound is largely unknown. In this study, B. cinerea isolates were collected from different districts of Shanghai province in 2015–2017, and their sensitivity to fludioxonil was determined. A total of 65 out of 187 field isolates (34.76%) were found to be resistant to fludioxonil, with 36 (19.25%) showing high resistance and 29 (15.51%) showing moderate resistance. Most of these resistant isolates also showed Citation: Wang, W.; Fang, Y.; Imran, resistance to iprodione, and some developed resistance to fungicides of other modes of action.

    MICHIGAN Grape facts Managing botrytis bunch rot Gray mold or bunch rot can cause serious yield loss but there are a variety of tools that can be used to protect grapes. By Safa Alzohairy and Timothy Miles; MSU Department of Plant, Soil and Microbial Sciences Key messages » Avoidance – Avoid cluster damage from other pests such as insects, birds and other grape diseases. » Exclusion – Exclude the pathogen by harvesting in a timely fashion and increasing canopy airflow. » Resistance – Choose resistant varieties when possible. Safa Alzohairy, MSU » Protection – Protect flowers and clusters with Figure 1. Botrytis bunch rot caused by Botrytis cinerea (cv. Riesling). fungicides when the infection risk is high. » Eradication – Eradicate old canes and clusters Disease symptoms each season. In early spring, infected buds and young shoots will turn brown, while in late spring, V-shaped, large, Pathogen irregular brown areas appear on the leaves (Figure Botrytis cinerea 2A). Grape inflorescences may appear blighted when infected but flower infection mostly remains Kingdom: Fungi quiescent until veraison (Figure 2B). At veraison Division: Ascomycota and beyond, the fungus infects the clusters directly from the skin or through wounds caused by various Class: Leotiomycetes factors including bird claws or feeding, insects or Asexual form: Botrytis cinerea rain cracks. Sexual form: Botryotinia fuckeliana or also known as Infected berries can dry out in arid conditions while Botryotinia cinerea in wet weather, infected berries are covered with grayish mold. This mold contains fluffy mycelia and Introduction millions of spores or conidia. As infection proceeds, Botrytis cinerea, or the causal agent of gray mold and bunch rot, is one of the most important pathogens of grapes worldwide.
