Tridge summary

[Agricultural, Fisheries, and Livestock Newspaper=Reporter Nara Park] The Chungnam Agricultural Research and Extension Services urged thorough preventive management for greenhouse farmers, especially those growing strawberries and other protected crops, as the risk of disease and pest outbreaks in greenhouses during winter is rapidly increasing. In winter, the drop in nighttime temperatures and large diurnal temperature variations lead to a rapid increase in humidity, creating an environment particularly conducive to the spread of diseases such as gray mold, powdery mildew, and downy mildew. Gray mold, a representative disease that occurs mainly from December to April, surges under low-temperature and high-humidity conditions around 20°C, making humidity control through heating and ventilation essential. During ventilation, care must be taken to ensure that cold winds do not directly hit the flowers to prevent frost damage.

Concerns over the spread of diseases and pests in winter greenhouses due to temperature fluctuations and high humidity... Emphasis on heating, ventilation, monitoring, and preventive medication management The Chungnam Agricultural Research and Extension Services urged that the risk of disease and pest outbreaks in winter greenhouses is increasing sharply, emphasizing the need for thorough preventive management for farmers growing protected crops such as strawberries. In winter, nighttime temperature drops and large daily temperature fluctuations cause humidity to rise rapidly, creating an environment where diseases and pests, such as gray mold, powdery mildew, and flower blight, are particularly likely to spread. Gray mold is a representative disease and pest that occurs mainly from December to April, increasing rapidly in low-temperature, high-humidity conditions around 20°C.
