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%.
this search has studied to know the effect of addition of three
resources (cows, sheep and poultry) and five levels (0, 7.5, 15.0,
22.5, 30.0) T/h, in some physical properties of soil, and some
characteristics of wheat, class Sham- 4. soil was sel
ected from (0-
30) cm of Ayash village in Dier AZ zour - sandy soil texture. The
experiment carried out in a pot capacity (9) kg using a (RCD) with
three replications.
Three systemic fungicides fenarimol, triflumizol, and triadimenol were used (mixed with mineral oil at 300 ml/100 L water or not) to evaluate the effects on powdery mildew of tomato in greenhouse. Results showed important role of mineral oil in inhan
cing the studied fungicides's effects by decreasing infection percentage and severity of the disease if the recommended doses are used or half of them. when these fungicides were used in low rates (50% of the recommended doses without mineral oil) infection percentage after a mounth of treating were 65.2 - 75.7% and severity 62.7 – 77.3% wherease when the fungicides were used with oil the infection percentage were decreased to 44.5 - 48.6% and severity to 16.9 – 45.8%
