Impact of some safety biotreatments in controlling cherry tomato powdery mildew [electronic resource].

Includes references.

Plant extract of anise (Pimpinella anisum L.), blue gum (Eucalyptus g/ohules L.), cumin (Cuminum cyminum L.), garlic (Allium sativum L.), marjoram (Majorana hortensis L.) and thyme (Thvmus vulgaris L.) were tested as foliar application to control Cherry tomato powdery mildew, caused by Leveillula taurica (Lev.). All treatments tested were significantly reduced the disease incidence and severity over untreated control. The plant extraction methods i.e., hot water, acetone and ethanol gave the superior results in controlling Cherry tomato powdery mildew disease incidence and severity, specially with each of blue gum, marjoram and thyme. With the exception of garlic plant extract, the cold water extraction method used with other plant materials unable to control the disease incidence and severity at all time of experimental application. Spraying Cherry tomato plant with microelements (Fe+Zn +Mn) led to an reduction of disease incidence and severity at all time of experiment. Also, the same trend was observed in case of the tested salts specially after 30 dayes of treatment.
