Neem oil is effective in controlling powdery mildew on plants due to its antifungal properties. It works by disrupting the growth and reproduction of the fungus that causes powdery mildew. However, its effectiveness can vary depending on the plant species and the severity of the infestation. It is generally considered a safe and natural option for controlling powdery mildew.
Due to the sediment within the river. this sediment causes the river to appear orange/reddish
Gravity is the force that causes sediment to settle in a riverbed. As the water flow slows down, due to decreasing velocity or obstacles in the river, the sediment particles start to fall out of suspension and settle on the riverbed.
