In vitro and in vivo screening of fungicides for controlling citrus melanose caused by Diaporthe citri

浙江大学学报. 农业与生命科学版, 2010
To verify the most efficacious fungicide for controlling citrus melanose caused by Diaporthe citri (Phomopsis citri), the inhibitory effects of four fungicides on the mycelial growth and conidial germination were assayed.

Studies on Citrus Melanose and Citrus Stem-End Rot by Diaporthe citri (Faw.) Wolf. Part 8. Distribution of Pathogen Inhibitory Substances in Citrus Tissues

Japanese Journal of Phytopathology, 1988
Even if citrus fruits are severely affected by melanose, they do not rot. This is considered to be due to some pre-inhibitins or phytoalexins induced in their tissues. The effect of extracts from leaves, twigs, fruit peel and fruit vesicles of citrus plants (satsuma mandarin and natsu-daidai) on pycnospore germination, germ tube elongation and disease ...

Chemical control of melanose-like blemish of citrus tree.

Kyushu Plant Protection Research, 1987
1. 枯れ枝上での分生胞子形成は6月,7月にAlternaria sp.8月以降にPhomopsis sp.が多い。2. 有機銅75水和剤による防除時期の試験では5月,6月散布の効果が高い。3. 黒点病,小黒点病(網型黒点,緑斑黒点)に対してはマンネブ水和剤,マンゼブ水和剤,ジネブ水和剤,ジチアノン水和剤の効果が高い。有機銅75水和剤,チアジアジン水和剤は効果は認められるがやや劣り,イプロジオン水和剤はまったく効果は認められなかった。4. 分生胞子形成の時期的推移,果実の感受性の推移,有機銅75水和剤の防除時期試験および各種薬剤の効果試験の成績等から果面の小黒点は主として黒点病菌(P.citri)と小黒点病菌(P.medusaea)の感染によると思われる。5.
