藏品描述：露菌病是一種真菌病原體，影響十字花科的栽種植物及野生雜草。對於大規模生產的捲心菜、西蘭花、花椰菜、蘿蔔、白蘿蔔、芥末、羽衣甘藍及十字花科植物等，露菌病是個嚴重的問題。在有利生長的狀況下，露菌病可能使得耕作時或收成後造成嚴重損失，導致包裝和運輸時產品質量下降。健全的栽種方式是治理疾病的重要策略，像是等衛生預防、輪作及有效行距。殺菌劑和抗病品種（僅限西蘭花）也可用於綜合疾病管理計劃。
Downy mildew is a fungal pathogen that affects all cultivated plants and weeds in the crucifer family. It can be a serious problem in commercial production of cabbage, broccoli, cauliflower, radish, turnip, mustard, collard, and cruciferous greens. Under favorable conditions, it may cause serious losses in the field or may develop after harvest and cause deterioration of product quality during packing and shipping. Sound cultural practices, such as sanitation, crop rotation and effective row spacing, are important tactics used to manage the disease. Fungicides and disease-resistant varieties (broccoli only) are also available for use in an integrated disease management program.
