Suspended seed coating for preventing and controlling Echinocnemus squameus (Billberg) and application thereof

The invention discloses a suspended seed coating for preventing and controlling Echinocnemus squameus (Billberg) and application thereof. The seed coating is prepared from the following components in percentage by mass: 30 to 60 percent of main component, 10 to 20 percent of assistant, and the balance of water, wherein the main component is a mixture prepared from imidacloprid and chlorantraniliprole in a weight ratio of (10 to 40) to (5 to 20). A paddy rice suspended seed coating is characterized in that the chlorantraniliprole and the imidacloprid are compounded to obtain an effective component, so that a remarkable synergistic effect is achieved, a good effect of preventing controlling the Echinocnemus squameus (Billberg) is achieved, and the lasting period is long; compared with pesticides such as dimehypo, methamidophos, fenitrothion, DDVP (Dimethyl Dichloro Vinyl Phosphate), trichlorphon and dimethoate, the suspended seed coating has the advantages of reducing dosage and enhancing the effect of preventi
