| Summary: | In vitro control of Alternaria solani included studies of different fungicides, essential oils basil and ethyl extract of Allium cepa. In Romania in the case of tomato culture it is very low due to several production constrains including diseases. One such disease is the early blight caused by fungus Alternaria solani (Ell.) Martin. The isolate used in this study was obtained from tomato and it was cultivated on three culture media: potato dextrose agar (PDA), malt extract agar and Czapek Dox medium. Using chlorothalonil, thiophanate methyl, prochloraz, tebuconazole and cooper sulphate, they were evaluated in order to control colony growth of fungi, at the concentrations recommended in agriculture by the specialized literature. The extract of Allium concentration with three levels (3%, 75% and 100%) significantly stronger effect on reducing mycelia growth, reducing spore germination and causing high inhibition percentage of A. solani. The fungal effect of the essential oil basil is very low being close to that of the control. |
