The present invention refers to a composition based on algal and/or plant extracts and its use in agriculture to improve water use efficiency and/or water productivity in plants and/or agricultural water management thus resulting in increased yield of crop plants per unit water used.

Provided is a repellent material capable of maintaining a stable repelling effect for a long period of time. A pest repellent material of the present invention includes porous particles including primary particles forming pores and aggregating, and an insect repellent component present in the pores. The primary particles contain silica as a component, and in an infrared absorption spectrum of the pest repellent material, a ratio (I.sub.1/I.sub.2) of the maximum absorbance (I.sub.1) at 3730 to 3750 cm.sup.−1 to the maximum absorbance (I.sub.2) at 1160 to 1260 cm.sup.−1 is 0.005 or less. A contact angle of the porous particles with water is greater than 90°, and the contact angle of the porous particles with the insect repellent component is 1° to 90°. It is preferred that 2 to 5 ml of the insect repellent component is contained based on 1 gram of the porous particles.

A method for producing a fermentate including the steps of obtaining a fruit or vegetable extract, treating the extract with a hydrolytic enzyme, mixing the extract with a fermenting microorganism, water, and a growth media to produce a liquid composition; and incubating the liquid composition at a controlled temperature and a controlled pH to produce a fermentate. A method for killing or inhibiting the growth of a contaminating microorganism on or within a food product, and a food product including a fermentate having a cellular mass component from a fermenting microorganism, a fermented fruit or vegetable extract and a hydrolytic enzyme are disclosed. A fermentate produced by any one of the methods described is contemplated. The fermentate may be a concentrated liquid or a dry powder and has the ability to inhibit the growth of a contaminating microorganism by 100% when diluted to less than 5% (w/v).
