我是河北永清的菜农,种植大棚黄瓜已有五年了,每年都因为黄瓜霜霉病让我头疼,经常背着喷雾器去棚里打药,但病情只能得到短暂的控制,两三天后霜霉病又起来了,而且霜霉病一旦发生,很快就病斑连成片,整个叶成黄褐色,干枯卷曲,整个瓜棚濒临死亡。听宣传介绍说银法利效果不错,我就抱着试试看的心态买了两袋,回来仔细看了使用说明后就在一个棚里用上了银法利。 I was a vegetable farmer in Yongqing, Hebei. It has been five years since I planted greenhouse cucumbers. I suffer from cucumber downy mildew every year. I often carry sprayers to shed drugs. However, the condition can only be controlled for a short time. After two or three days of frost Mold disease is up again, and downy mildew in the event of a disease quickly spot even into pieces, the entire leaf into a brown, dry curly, the entire melon shed on the verge of death. Listen to the publicity said Silver Farley good results, I took a try try to buy two bags, came back carefully read the instructions after using a silver spoon in a shed.
