Abstract

Since years, many plants contain components that have antifungal effect against plant pathogens. As a biological control, several plant extracts, belonging to the family of Amaranthaceae, have been tested against some phytopathogenic fungi from different crops. For this, an antifungal test of an indigenous plant extracts from the south eastern Algeria was evaluated for its inhibitory effect on phytopathogenic fungicausing date palmdiseases, Alternaria sp., Fusarium sp., Phytophthora sp. and Cladosporium sp.The aqueous extract of this plant showed the maximum inhibition with Phytophthora sp.which recorded 90,6 % at 100% and 83,0 % at 50%, followed by Cladosporium sp. (D2: 89,02%; D3: 89,10%; D4: 86,15%). Statistical analysis confirms that all the doses of H. strobilaceum had a significant effect, comparatively with the control, of inhibition against the tested phytopathogenic fungi mentioned before with p < 0,05; p = 0,0087. High inhibition was detected against Phytophthora sp. and Cladosporium sp. with all the doses, unlike, Fusarium sp. was exhibited only in the fourth dose and Alternaria sp. that was revealed a low rate in the fourth dose. These effective plant extracts may contribute to development of potentially effective and environmentally safer alternative fungicide to control date palm diseases caused by these phytopathogenic fungi.
