The invention relates to a method for preventing and controlling taro aphids and red spiders through organic silicon physical barrier piercing-sucking. The method comprises the steps that insect prevention treatment is carried out, 20% potassium silicate solution is mixed with water to form 1000-fold particle suspension, aiming at the characteristic that adults and nymphs of taro aphids and red spiders pierce and suck juice on leaf backs or tender leaves, 1000-fold solution of 20% potassium silicate is sprayed in sunny days at the early stage or before the taro aphids and the red spiders are damaged, and it is guaranteed that rain does not occur two hours after spraying; and 1000-fold suspension of 20% potassium silicate can form a particle breathable film with nanoscale aperture on taro plants, and the particle breathable film can physically block piercing and sucking of aphids and red spider imagoes with micron apertures, and nymphs on taro leaves. According to the method for preventing and controlling the
