3.供試Takeda-mer, Duter, Suju, polyram-combi, Brestan 60, Dithane M45, Antracol, Difolatan等8種藥劑，其濃度500ppm者皆對本菌菌絲生長及胞子發芽有抑制作用，而對缽栽蘆筍病株之防治效果，以Difolatan最好，Duter及Suju次之，Takeda-mer, Dithane M45，及Polyram-combi又次之。
The physiological characteristics and chemical control of Phoma asparagi were studied. The results have been summarized as follows:
1. For the mycelial growth, the optimum temperature was 25° to 28°c, the optimum pH range was 6 to 8, the optimum NaCl concentration was 0.3 to 3%, and the optimum sucrose concentration was 8%.
2. The mycelia formed on the agar media and on the stems of asparagus remained active after 150 days at low temperature (-5°c).
3. Eight fungicides were evaluated for their effectiveness in inhibiting the myclial growth and spore germination and in cotrolling the infectivity of the causal organism under laboratory condition. Takeda-mer, Duter, Suju, Polyram-combi, Brcstan 60, Dithane M45, Antracol and Difolatan showed the inhibiting effect on the myclial growth and spore germination at the concentration of 500ppm respectively. Difolatan showed the best con-tolling effect on the infected plants of asparagus, Duter and Suju the better, Takeda-mer, Dithane M45 and Polyram-combi the next.||en_US|
