Methods of controlling shell insects on flowers

First, mix liquor with water, the ratio is 1: 2, when controlling insects, pour through the surface of the basin soil. Scale insects begin to move when the room temperature is 7 degrees Celsius in spring, and can be irrigated once in April, and then every half a month or so, four times in a row.

Second, with 50 ml of vinegar (rice vinegar), soak the small cotton balls in vinegar and gently wipe the damaged stems and leaves with wet cotton balls to wipe off the shell insects. This method is convenient and safe, which can not only achieve the purpose of disinfestation, but also make the injured leaves turn green again.

Third, if you wipe the diseased plant gently and repeatedly with alcohol, you can get rid of the shell worm.
