Megjegyzések:	Onion is one of the most important export crops in Egypt; its productivity and exportation is restricted mainly by purple blotch disease. In vitro and field experiments during two growing seasons were conducted aiming to improve control of Alternaria porri (the pathogen causing purple blotch disease) by the application of combinations of elemental sulfur (S-0) and Trichoderma spp. (T. harzianum and T. viride). Fungicide (Ridomil Gold M Z-68% WG) was applied as pesticide treatment control. In vitro experiments revealed that supplementation of S-0 at 2 g L-1 to the growth medium that was utilized to culture Trichoderma spp. inhibited (100%) the growth of Alternaria porri. Trichoderma viride showed higher efficiency in controlling purple blotch than T. harzianum, and resulted in disease controlling rates that were similar to those by fungicide (Ridomil Gold). Disease incidences decreased by 63.9% in onion plants that were inoculated with T. viride, compared to 66.3% when fungicide was applied. Also, antioxidant activity of catalase and peroxidase was the highest when S-0 was applied at 240 kg ha(-1) and the onion plants were treated with T. harzianum and/or T. viride. Application of S-0 at 240 kg ha(-1), in combination with inoculating onion seedlings with T. harzianum, led to enhanced onion growth and yield over fungicide application (traditional practice of farmers) in both seasons. As a result, green bulb yield (t ha(-1)) and total soluble solids (TSS, %) were 41.9 and 21.7% higher, respectively; harvested dry bulb (t ha(-1)), marketable bulb yield and TSS were 33, 35 and 13% higher, respectively; while nonmarketable bulb yield was 21.5% lower than those under fungicide application.

Cím:	Disease suppressive soils vary in resilience to stress / Thomas F. Döring, Dagmar Rosslenbroich, Christian Giese, Miriam Athmann, Christine Watson, Imre Vágó, János Kátai, Magdolna Tállai, Christian Bruns

Megjegyzések:	Soil-borne plant diseases are a major source of crop losses. Biologically active soils have the ability to suppress pathogenic infections of plants, but little is known how this essential soil function might be affected by abiotic stresses. Using a model system with pea and its fungal pathogen Pythium ultimum we studied how the suppressiveness of different soils from a wide geographic range responds to combined heat and drought stress. We found that different soils strongly differ in their ability to suppress diseases and that a stress event of combined heat (40 ?C) and drought (?50% moisture) can strongly reduce this disease suppressiveness. Further, the response of suppressiveness to the stress depended on the provenance of the soil. Soils from a cool-climate site in Scotland were much more negatively affected than soils from warmer sites in Germany and Hungary. After being exposed to stress, one soil was able to regain suppressiveness after several weeks while the others were not, thereby collectively showing different degrees of resilience to the stress. Stress tolerance was negatively related to resilience. Our results suggest that microbial communities responsible for suppressiveness are adapted to prevailing climate, which has potentially severe consequences for the impact of climate change upon plant health.
