In the present paper the methanol extracts obtained from 10 cultivars of Tagetes patula were assayed on two phytopathogenic fungi: Botrytis cinerea and Fusarium moniliforme.

F. moniliforme seems to be a more resistant test that does not appear to be affected by the different treatment conditions (light-dark) even at the highest dose. However, it can be asserted that Tagetes patula is a possible source of antifungal substances and that thiophene activity is, in general, strongly increased by UV-A irradiation. During the experiment the method of chromatographic plates was used to evaluate plant extracts bioactivity.

Abstract

In the present paper the methanol extracts obtained from 10 cultivars of Tagetes patula were assayed on two phytopathogenic fungi: Botrytis cinerea and Fusarium moniliforme. B. cinerea showed a high dose-dependent inhibition, with a marked difference between light and dark treatment. F. moniliforme seems to be a more resistant test that does not appear to be affected by the different treatment conditions (light-dark) even at the highest dose. However, it can be asserted that Tagetes patula is a possible source of antifungal substances and that thiophene activity is, in general, strongly increased by UV-A irradiation. During the experiment the method of chromatographic plates was used to evaluate plant extracts bioactivity. The obtained data indicate that it is a rapid method than can be used as an alternative to Petri dish tests.
