Yellow spots appear on the leaves of cucumbers during growth. These yellow spots affect the normal growth of cucumbers. In severe cases, they cover the entire leaves until the cucumbers die.
To completely cure the "yellow spots" caused by this situation, it is very important to kill spores in the shed, but it cannot rely on spraying alone. The combination of aerosol smoked sheds and spraying has a good effect. Because only the aerosol can completely destroy the pathogenic spores on the ground, shed membranes, walls, columns, etc. in the shed. Can use 400 grams of speed smoke agent 400, smoked at night, during the day spray 75% chlorothalonil 600 times mixed 50% thiophanate-methyl spray 500 times, focusing on the back of the leaves spray.
