Abstract: For the first time, the excellent insect-resistant activity of a Zingiberaceae plant extract on pests such as agricultural pest mites and thrips and a compounding synergism and co-extraction synergism relationship among extracts of different species of the Zingiberaceae is discovered, an application range of the Zingiberaceae extract is expanded, and a new choice for controlling the pest mites and thrips in agriculture is also provided.

Abstract: The present disclosure provides a novel brassinosteroid (BR) analogue, a novel crystal form, and a preparation method and use thereof. The BR analogue has a chemical formula of C27H46O7, a chemical name of (20R,22R)-2?,3?,14?-14,20,22,25-hexahydroxy-5?,8?,9?-cholestan-6-one, and a structural formula of: In the present disclosure, a novel crystal form with a high bioactivity is obtained by improving a recrystallization process of a naturally extracted BR analogue. This novel crystal form can be applied in the field of agriculture to promote the growth of plants.

Abstract: A new type of defoliant and the application thereof, specifically the application of a polyether compound in the preparation of defoliant, belonging to the technical field of pesticides. At least one of the polyether compound shown in Formula I (R1O(CH2CHOH)nR2) or salts thereof is used for preparation of defoliants or defoliation synergists, wherein, the R1 is a hydrocarbyl or a phenolic group; the R2 is —H, —O(CH2CHOH)mH or —O(CH2CH2CHOH)mH; the n is 1-50, and m is 1-50. The compound is a new defoliant featured with low cost, convenient usage and favorable defoliation effect, and it is safe for the environment.

Abstract: The present invention relates to a ball-throwing scoop for interaction with a pet, comprising a scoop body and a handle. The scoop body includes a scoop opening, two sides and a base portion. The scoop body resembles a smaller half of a circular tube or approximately circular tube longitudinally cut off, the longitudinal central axis y of which is an arc having a larger radius R; r is used to denote the radius of the smaller half of the circular tube, R>>r; the base portion of the scoop body is connected to the handle in the shape of a hollow cylinder, the central axis of the handle obliquely intersects the longitudinal central axis of the scoop body, a cavity of the handle can store liquid or solid pet drinks/foods, especially a cylindrical biscuit box.

Abstract: A toy slingshot for interacting with pets, comprising a slingshot fork, a rubber band installed on said slingshot fork, a shooting pocket connected to said rubber band, and a handle connected to said slingshot fork, wherein a circular ball sleeve is provided at a lower position within a fork opening a top surface of the circular ball sleeve having a gap, and a plane of said ball sleeve coincides with that of said slingshot fork. Said handle comprises a left half handle and a right half handle, and upper ends of said left half handle and right half handle are fixed to a connector at a bottom portion of said slingshot fork, forming an integrated handle having an internal a cavity. The lower-most end of said handle is connected to a handle cover, and the cavity in said handle holds a cylindrical cookie box.
