One man was taken to hospital with what is understood to be non-life-threatening injuries after a tree fell onto his car on the A515 in Derbyshire. Fallen trees cause injury, damage and disruption ...
Aphanomyces root rot can account for yearly losses of about 10% in the fields where it occurs, and may cause losses of entire fields in conditions that are favorable to the pathogen. In agricultural regions that produce large amounts of susceptible crops and have favorable weather conditions for A. euteiches , careful monitoring is of paramount ...
