Is washing machine water good for plants? The main component of laundry detergent (including common daily detergents) is sodium dodecylbenzene sulfonate and its auxiliary substances, which are easily soluble in water, and its aqueous solution has an alkaline reaction.
It is mainly touch-kill for pests and can inhibit the hatching of mite eggs. When laundry detergent is sprayed on the insects, it dissolves the wax on the insects and adheres to the insects, forming a film to occlude the stomata and suffocating the pests to death.
The water of laundry detergent has a good effect on the four major pests that often occur in household potted flowers, namely aphids, red spiders, whiteflies, and moths.
Some florists say you can mix one gram of laundry detergent with four hundred milliliters of water and then spray it on the leaves of the plant, once every two weeks, to kill the flies in potted plants.
If you use laundry detergent water to kill the insects, you should also pay attention to rinse off with water in time to do so.
