Abstract
The invention discloses aphid control liquid and a preparation method thereof. The aphid control liquid comprises a Chinese herbal medicinal extracting solution and an ethanol aqueous solution, wherein the mass ratio of the Chinese herbal medicinal extracting solution to the ethanol aqueous solution is 1:(30 to 50); the Chinese herbal medicinal extracting solution is an extracting solution of tobacco stem, cayenne pepper, radix euphorbiae ebracteolatae, euphorbia lunulata and ixeris sonchfolia; the mass percentage concentration of the ethanol aqueous solution is 0.3 to 0.5 percent. According to the aphid control liquid disclosed by the invention, no chemical pesticide is contained, and aphids can be effectively controlled and killed; in addition, problems in aphid control in 'six unused' pesticides, organic agriculture and green pesticides can be effectively solved, and the ecological environment can be protected.
Description
technical field [0001] The invention relates to an aphid control liquid and a preparation method thereof, belonging to the field of plant pest control.
