It is then dead tissue, and open to attack by coral spot fungus.

Saprophytic fungi like coral spot on mulch are an indication of insufficient hoeing.

Nectria cinnabarina is a plant pathogen that causes cankers on many tree species and also a disease known as coral spot.

I have had many letters asking for advice and questioning the use of bark and shavings because of coral spot fungus appearing.

Some species are significant pests causing diseases such as apple canker, Nectria twig blight, and coral spot in orchards.

Specializing in phytopathology, Heybroek also investigated the Coral Spot fungus Nectria cinnabarina in elm.

The tree is susceptible to leafhoppers, scale insects and psyllids (specifically Cacopsylla pulchella) as well as diseases including canker, coral spot and verticillium wilt.

Coral spot with its orange pustules is dealt with in this way, while any rose leaves stricken with the ubiquitous rose black spot are picked off and burnt.

Old leaves, twigs and bits and pieces left lying about are the ideal propagating material and position for mildew, black spot, coral spot and all manner of troubles.

Moderately resistant to Dutch elm disease, and more resistant to Coral Spot fungus Nectria cinnabarina than its forebear 'Christine Buisman'.

Moderately resistant to Dutch elm disease (DED), but very prone to cankers caused by Coral Spot fungus Nectria cinnabarina as it lacked resistance mechanisms.

Other diseases include Bacterial Wetwood, various viral and fungal diseases, cankers including Coral Spot, and root diseases caused by Cinnamon Fungus or Honey Fungus.

Tests in Italy confirmed the American findings, and also determined a moderately high susceptibility to Elm Yellows, meanwhile in the Netherlands the species was also found to be susceptible to coral spot fungus Nectria cinnabarina.

Although the 'Christine Buisman' elm didn't meet the general expectations concerning its growth habit, and appeared to be susceptible to Coral Spot fungus, Nectria cinnabarina, many mature specimens still survive in Holland, England and the USA as living proof of her achievement.
