Abstract
Process for protecting plants from diseases caused by airborne carriers by application of a stable W/O paraffin emulsion. The emulsion is produced by emulsifying a hard paraffin having substantially the same number of carbon atoms naturally present on said plants with a C.sub.12 -C.sub.18 fatty acid soap under conditions such as to yield an emulsion particle size of 1 to 5 microns.
Claims13
A method for protecting plants from diseases caused by airborne carriers which comprises:
- applying to a plant, an effective amount to protect said plants against such airborne diseases, of a W/O emulsion of a hard paraffin having substantially the same number of carbon atoms as that naturally present on the surface of the plant;
- said emulsion being prepared by emulsifying said paraffin with a C.sub.12 to C.sub.18 fatty acid soap to produce an emulsion having colloidal particles consisting essentially of those within the range of from 1 to 5 microns;
- said emulsion, after evaporation of water therefrom depositing a block-like film of paraffin on said plant.
