Speaker: Dr Glynn Percival
Tree diseases are controlled primarily by spray applications of fungicides. Increased legislative restrictions regarding the use and application of fungicides stimulated by a greater environmental awareness means new techniques of disease control are required. Induced resistance (IR) is the phenomenon whereby a plant's own defense mechanisms are switched on by treatment with either a biological or chemical agent. This webinar will discuss the effectiveness of soil applied IR amendments (biochar, chitin, mulch) on enhancing tree resistance against a range of diseases frequently encountered in urban landscapes.
