COMPOSITION AND METHOD FOR PLANT PROTECTION

摘要

13 protein mushroom extracts and 1 protein extract from mycelium with antibacterial activity against R. solanacearum have shown activity in tests. Moreover, an A. phalloides protein fraction also completely inhibited bacterial growth. The extracts and fractions not only displayed potent inhibition of bacterial multiplication but more commonly displayed bactericidal effect, rather than bacteristatic. In vivo testing of 5 selected extracts on tomato and potato plants lead to a conclusions, that C. geotropa, S. variegatus and T. saponaceum extracts lower disease occurrence and delay bacterial wilting on both tomato and potato plants. Thus, mushroom protein extracts of the present invention are an important tool to treat bacterial wilt caused by R. solanacearum. Moreover inhibition of 12 R. solanacearum strains as well as R. mannitolilytica and E. coli by mushroom protein extracts proves their broad spectrum activity, which could be beneficial in the fields of medicine, biotechnology, waste management/bioremediation and agriculture.
