A method of producing an agricultural product for improving immunity, the agriculture product being rice, includes: (1) soaking seeds of the agricultural product in a solution containing a magnetic material and a β-glucan; (2) before planting the seeds, applying a bottom fertilizer to a paddy field for the agricultural product, the bottom fertilizer including an organic fertilizer, the magnetic material, an oyster shell powder, the β-glucan and an organic zinc; and (3) at tillering stage, applying a topdressing to the paddy filed, the topdressing including the β-glucan and the organic zinc.

The invention provides materials and method for controlling pests using a composition comprising microbial hydrolysates and microbial growth by-products. In preferred embodiments, the growthby-products are biosurfactants, such as glycolipids and/or lipopeptides. The composition can be used in combination with other pesticides or pest repellents, preferably which are naturally-derived.

Provided herein are amphoteric glycolipid biosurfactants containing an amphoteric glycolipid biological surface active molecule preparation produced by acid precipitation of culture supernatant produced by sequentially culturing Pseudomonas, Candida, and Neurospora, for instance in a fermentation medium comprising a hydrophilic carbon source and a hydrophobic carbon source. Also described are amphoteric glycolipid biological surface active molecule preparations, and methods of making such preparations. The amphoteric molecules have anionic and cationic groups; example molecules include 17-L-[(2′-O-β-D-glucopyranosyl-β-D-Glucosyl)-O-]-octadecenoic acid amine-6′,6″ diacetate, and 17-L-[(2′-O-β-D-glucopyranosamine-β-D-rhamnosyl)-O-]-octadecenoic acid-6′,6″ diacetate. The amphoteric glycolipid biosurfactant has good compatibility with other types of surfactants, high temperature resistance and salt resistance, and is suitable for use in a variety of liquid systems.

The present specification discloses compositions, articles of manufacture, containers or kits comprising such compositions, and methods and uses to control a causal agent of a plant disease, increasing plant growth and/or food production and/or improving performance of an irrigation system(s).
