Aluminum phosphide can not be used to control rice planthoppers
Aluminum phosphide is a broad-spectrum fumigating insecticide and is mainly used for fumigation to kill various kinds of pests in warehouses and also to eradicate rats. The aluminum phosphide absorbs water and produces toxic phosphine gas. The phosphine enters the body through the insect's respiratory system and acts on the respiratory chain and cytochrome oxidase of the mitochondria of cells, inhibiting insects from normal breathing and killing insects. Wolfberry also has a good control effect. However, when the drug encounters water, it rapidly produces phosphine that is highly toxic to humans. Do not use it for rice field control of rice planthoppers. Otherwise, it can easily cause human poisoning.
