摘要：
A variety of plant diseases and damage by certain pests in agricultural and horticultural plants can be efficiently controlled without substantial chemical injuries by applying a plant-protecting composition which comprises (a) 1 part by weight of a chitosan hydrolyzate having an average molecular weight of 10,000 to 50,000, obtained by acid hydrolysis or enzymatic hydrolysis of chitosan and (b) 0.25 to 4 parts by weight of acetic acid. Any possible chemical injury to plants caused by applying the composition can be further reduced when the composition is admixed with a deproteinized juice of alfalfa leaves.
