Root rot is considered one of the serious widely spread tomato diseases in
plastic houses culture of Syria. Soil solarization, using transparent polyethylene
(PE) covering, was applied during July and August (١٩٩٤-١٩٩٦) in Tartoos
governorate for
controlling soilborne pathogenic fungi. Results indicated that,
native fungal populations in covered moist soil supplied with or without sulfur
were significantly reduced in comparison with the uncovered treatment.
The research aims to Identify some species of aphids on plant families, and test the
possibility of transfer to the local isolate of Cucumber mosaic virus. Two species of aphids
in bean fields and citrus orchards have been defined, namely: Black be
an aphid Aphis
fabae and Cotton aphid Aphis gossypii, respectively, depending on the specialized
classification keys. The infection proved vital feedback and testing the function using
plants: Nicotiana tabacum and Chenopodium quinoa transfer each of the A. fabae and A.
gossypii local isolate of Cucumber mosaic virus.
This investigation was carried out in a plastic house (350 m² area) located at Tishreen
University in two seasons 2007-2008 and 2008-2009, to study the effect of soil solarization
in soil borne fungi in greenhouse. With four treatments: the control
treatment,
Soilsolarization: 30, 40, and 50 days, and 0, 5, 10, 15 and 20 cm depth. The solarized soil
covered with transparent polyethylene.
