Abstract
PURPOSE: A cold resistance improver for the foliar application, containing an aqueous solution of a water-soluble condensed phosphate, and capable of improving the cold resistance of perennical plants, e.g. apples, grapes or mulberry trees, such as prevention of emergence disorder due to the coldness.
CONSTITUTION: A cold resistance improver for the foliar application, containing an aqueous solution of a water-soluble condensed phosphate, and usable for perennial plants. For example, an orthophosphoric acid is mixed with phosphoric acid anhydride and condensed under heating to give condensed phosphoric acid with a phosphoric acid content of 83% (as P2O5). About 85% of the free hydroxyl groups in the resultant condensed phosphoric acid are then neutralized with potassium hydroxide to give the aimed cold resistance improver. The concentration of the improver is adjusted to about 0.05W1% for use. The twig blight of mulberry trees, sleepiness (inhibition of germination) of grapes, etc. can be prevented. The resistance of the perennial plants to pathogenic germs or wet injuries are also improved.
