Plâu a Chlefydau: bygythiadau, diagnosis a hysbysu
Mae’r hanfodol bod plâu ac afiechydon yn cael eu cofnodi’n gywir cyn y gallan nhw gael eu rheoli’n effeithlon a chyn y gellir rhwystro eu lledaeniad. Yn y cyflwyniad hwn bydd Dr Perez Sierra yn disgrifio’r broses ddiagnosis a’r dechnoleg newydd sy’n cael ei defnyddio. Ar hyn o bryd rydyn ni’n wynebu nifer o fygythiadau o blâu ac afiechydon newydd sy’n cyrraedd o dramor. Mae Xylella fastidiosa yn bathogen bacteriol sydd ag ystod eang o letywyr ac sy’n achosi difrod helaeth yn Ewrop. Mae angen i ni fod yn ymwybodol o’r pathogen hwn a sut i’w atal. Felly, mae’r cyflwyniad yn astudio’r bygythiad hwn yn fanwl. Yn dilyn y cyflwyniad bydd sesiwn Holi ac Ateb fyw i gyfranogwyr y Gynhadledd roi eu cwestiynau i’r arbenigwyr diagnosis ac iechyd coed.
