The application discloses an immune
elicitor for inducing the resistance of apple trees to aphids and application thereof, relates to the field of agricultural ecological technology, and aims to solve the technical problem of easy oxidation and inactivation of
active components in the long-term storage process of the current immune
elicitor for apple trees. The preparation mode of the
elicitor is limited domain
coating matrix construction, active elicitor
system introduction and response regulation component introduction. In the spraying process of the response regulation component, the wettability and spreading ability of the
pesticide solution on the surface of the
apple tree leaves are improved through the organic
silicon component. The three-dimensional composite network
coating system composed of modified
nanocellulose and
sodium alginate is constructed, so that the active elicitor component is stably limited in a low
diffusion environment. Meanwhile, the
ion action mechanism of the response regulation component in the spraying process is combined, the gradual release of the active elicitor component in the application stage is realized, and the synergistic balance between the storage stability and the application effectiveness is realized.
