柳橙綠黴病藥劑控制改進之研究

Studies on Green Mold Control of 'Liu-Cheng' Orange (Citrus sinensis) with Fungicides

「依滅列」能極有效的抑制綠黴菌孢子之發芽和菌絲之生長，並且對人工接種之柳橙表現甚佳立防腐效果，顯示「依滅列」在柳橙採收前、後具有較佳之應用價值，「貝芬硫醌」對抑制綠黴孢子發芽之效果最佳，在實際應用上亦具潛力。「億力」、「腐絕」、「貝芬得」亦能控制綠黴果腐，然與「依滅列」及「貝芬硫醌」相比，其效果稍遜。

Benomyl-resistant strains of green mold (Penicillium) were collected from-citrus orchard at Chia-yi area. These resistant strains were tested to screen fungicides on green mold rot control. Imazalil obtained very effective inhibition on spore germination and mycelium growth of green mold. This fungicide also did a good result on decay control in Liu-cheng oranges. It is showed that Imazalil would have widely usage for controlling decay of citrus fruits before or postharvest. Delan-C gave excellent inhibition of spore germination and also provided good control of green mold rot in Lin-cheng oranges. The fungicides of Benomyl, Meftect and Bavistin had less effect on spore germination and less value for rot control than Imazalil or Delan-e.
