Abstract: A method, device, system and computer-readable medium for rapidly detecting a pest egg in a grain based on a pest egg structure feature and a pest hole structure feature is disclosed. The detecting method includes acquiring a gray digital image of a grain pile and three-dimensionally reconstructing it to obtain a three-dimensional image of a multi-grain pile; segmenting the three-dimensional image of the multi-grain pile to obtain one or more grains-contained unit images; identifying pest hole areas in each of one or more grains-contained unit images based on a biological feature of a pest; determining whether the pest hole area is a pest egg area based on the pest hole structure feature; and determining whether an alive pest egg exists in the pest egg area based on a geometric feature and a physical feature of the pest egg.

Abstract: A method of inhibiting the growth of Pseudomonas syringae on a plant material, the method including applying, to the plant material, with a composition including an effective amount of one or more acetates. A composition for inhibiting the growth of Pseudomonas syringae on a plant material includes an effective amount of one or more acetates selected from the group consisting of sodium acetate, iron acetate, potassium acetate, lithium acetate, magnesium acetate, calcium acetate, aluminum acetate, and nickel acetate. A kit for treating an infection caused by Pseudomonas syringae on a plant material, the kit including one or more acetates.
