Abstract

The invention discloses a prevention and control agent for spartina alterniflora and a use method thereof. The prevention and control agent for spartina alterniflora is prepared from the following rawmaterials in parts by weight: 15 to 20 parts of 2-amino-4-[hydroxyl(methyl)phosphonyl]ammonium butyrate, 8 to 12 parts of 2-(4,6-dimethylpyrimidin-2-ylcarbamylaminosulfonyl)benzoate, 20 to 25 parts of auxiliary agents and 70 to 80 parts of water, wherein the auxiliary agents are composed of 3 to 5 auxiliary agents selected from a group consisting of ammonium sulfate, Silwet 618 (625), Tween 20, polyvinyl alcohol, SAG622 (1572) and sorbitan ester fatty acid ester. With the prevention and control agent, the death rate of spartina alterniflora can reach 90% or above, and benthic organisms (shellfishes, mud flat crabs and the like) are not significantly affected, so the ecological safety of the prevention and control agent is high.

Description

technical field [0001] The invention belongs to the prevention and control technology of Spartina alterniflora in coastal tidal flats, and in particular relates to a Spartina alterniflora prevention and control agent and a preparation and use method thereof. Background technique [0002] Spartina alterniflora has been listed by the IUCN as one of the most vicious invasive species selected from alien species in the world as one of the bad weeds of aquatic plants. In 2003, the State Environmental Protection Administration of China and the Chinese Academy of Sciences jointly announced the first list of invasive alien species that invaded my country. Spartina alterniflora was listed as the only coastal salt marsh plant. This plant has become the most important invasive plant on coastal tidal flats in my country. . The control of Spartina alterniflora has become one of the main issues in the ecological management of coastal tidal flats and the restoration of sustainable coastal e...
