The aim of this study is to determine the percentage of loss in yield of some durum wheat varieties against wheat leaf rust, and to identify whether the slow rusting has a positive effect in limiting yield loss. The study was carried out in the field
s of experiments at Faculty of Agriculture, Aleppo University, Aleppo, Syria, 2015, included six durum wheat varieties (Cham1, Cham5, Douma1, Cham9, Beltagy and Massine).
The corrosion inhibition of transmision steel in 1M HCl solution in
the presence of Vanillin at temperature (20,30,40,50,60)°C at
concentration between (100-500) ppm for two hours were studied
using weight loss method.
The corrosion inhibition of transmision steel in 1M HCl solution in
the presence of Succinic acid at temperature (20,30,40,50,60)°C at
concentration between (10-6- 10-4) M for two hours were studied
using weight loss method.
A number of diseases attack wheat crop in Syria. Yellow rust or stripe rust
(Puccinia striiformis West f. sp. tritici) is considered the most important rust
disease of wheat in the cool and humid wheat growing area. The disease spread
in all wheat
growing areas in Syria specially in the irrigated and humid area.
To identifey the distribution and severity of the disease during the two seasons
1999-2000 and 2000-2001، field survey have been conducted in 76 fields in the
first season and 73 fields in the second season in different wheat growing area
in Syria.
