Biological Control and Tissue Culture

Pelargonium (Pelargonium graveolens L.) is one of the most important aromatic crops in many parts of the world as well as in Egypt. It is used also as ornamental crop in many gardens. The present studies aimed to recognize the effect of bioproductes and biofertilizers as bioagents, the effect of fungicide alternatives(plante extracts, essential oils, ascopien and potasien macro elements, and micro elements, yeast and garlic, and throw light on the importance of using tissue culture in decreasing the deterioration of productivity of Pelargonium graveolens plants
