AM-toxin을 이용(利用)한 사과점무늬낙엽병균(Alternaria mali)의 공기중(空氣中) 밀도(密度) 조사(調査)

The Use of AM-toxin in Monitoring the Numbers of Air-borne Spores of Alternaria mali Causing Leaf Spot in Apple Orchards

Changes in the numbers of air-borne spores of Alternaria mali causing the Alternaria leaf spot of apple were investigated in apple orchards, by monitoring their AM- toxin(host-specific toxin) producing ability. Most of the air-borne Alternaria in apple orchards were not AM-toxin producers. In culture, only about 2% of Alternaria isolates from a commercially managed apple orchards produced the toxin that was highly toxic only to susceptible leaves.
