摘　　要：通过发病规律及人工接种研究，明确了番茄灰霉病菌Ｂｏｔｒｙｔｉｓｃｉｎｅｒｅａ初侵染番茄果实的主要部位为残留的花瓣处及柱头处，随后扩展到果蒂部、脐部，最后蔓延到果实的其它部位。据此，在国内外首次提出了一种防治番茄果实灰霉病的新方法，在番茄用２，４－Ｄ蘸花后７～１５ｄ（幼果直径１０～２０ｍｍ）摘除残留的花瓣及柱头，防效达８０％以上，对番茄单果重无影响。The pattern of disease development in the solar greenhouse and results of artificial inoculation indicated that the key initial infection gates of Botrytis cinerea on tomato fruits were the residual petal and stigma, from which the infection extended to fruit stalk and navel, and finally to the other parts. Accordingly, a new method for controlling grey mould of tomato fruits was developed i.e. picking residual petal and stigma in 7-15 d after dipping flowers (10-20 mm diameter in young fruits) by using 2,4-D. Field test showed that the control effect was over 80% and without damage to fruiting.
