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.
This research was carried out in a field during the (2016)
season in Beit AL Raheb village . The agriculture was in (protected
and field under normal conditions) . two wheat variets were used :
Cham1 and Cham4.
To know the effect of some fungicides on peacock eye disease has beentested five
fungicides from different chemical groups, using concentrations advisable to field
application,on the 45 year old olive trees in the Baksa village Lattakia . The resul
ts
showed an increase in incidence of the control of 22.4 to 45.5 % after 45 days, versus low
incidence rates in the fungicides tested treatments . The best two fungicides were
thiophanate –methyl with infection decreasing from 19.2 to 10.3% and chlorothalonil from
24.3% to 16.5% . The severity also decreased in the treatment of the fungicide thiophanate
–methyl from 9.7 to 4.1 % and chlorothalonil from 13.7 to 8.9 % while the severity of the
infection of the control increased from 10.5 to 25.6 % .In order to efficiency the fungicide
thiophanate – methyl was more effective reducing the infection severity compared with the
control with 82.8 %, followed by chlorothalonil , kresoxsim methyl , and mancozeb with
73.3 , 72.0 , 71.9% respectively whereas the fungicide copper oxychloride was the least
effective with 68.1%.
The effect mycorhizal fungi on tomato wilt disease caused by Fusarium oxysporum
was studied. The results showed that % of disease incidence reduced in treatment whit
mycorrhizal fungi . % of disease incidence reached to 33% when plants infected wit
h
mycorrhizae and Fusarium wilt compared to plants infected with Fusarium wilt just
where% of disease incidence reached to 70% .The results showed a sighificant increased in
plant height ,leaf number , fresh and dry matter of shoot and root in treated plants with
mycorrhiza and Fusarium wilt compared whit treated plants with Fusarium wilt.The
increase in plant height reached 24.13% ,16.93% in leaf number,36.13% in wet weight of
shoot ,48.14 in wet weight of root,30.37% in dry weight of shoot and 29.18% in dry
weight of root in treated plants with mycorrhiza and Fusarium wilt.
To determine the susceptibility of some olive varieties to the
disease of eye peacock, We studied the development of eye peacock
disease on 3 varieties (Khadairy - Zorzalina - Frontoio. The
percentage of infected leaves and the severity of infection were
estimated during spring and autumn months, the maximum period
of the spread of the disease.
