The work studied the effect of low molecular weight chitosan hydrolyzate on the growth and development of phytopathogens Botrytis cinerea, Fusarium solani, Alternaria solani . Chitosan hydrolyzate, when added to potato-glucose agar, inhibits the growth of mycelium in vitro of Botrytis cinerea, Fusarium solani, Alternaria solani . Treatment with chitosan hydrolyzate suppresses the development of fusarium on tomato leaves and the development of gray rot on fruits. Further studies of chitosan hydrolyzate effect mechanisms on plants can expand the scope of its application.
