تم في هذه الدراسة إجراء استبيان للتعرف على إنواع مبيدات الحشرات المستخدمة لنبات البندورة في الزراعة المحمية في الساحل السوري
In this research, 66 samples of tomatoes were collected from vegetables
central market in Darr´aa city during the period extended between 20
October/2009 - 4 October/2010) to investigate the presence of 26 pesticide
residues which belong to differ
ent chemical classes using Gas Chromatography
instruments equipped with μECD, FPD, MSD detectors. QuEChERS extraction
method was used for residue extraction from tomato samples. The detectors
linearity and pesticide detection limits were determined for every pesticide
studied, and the recovery for all pesticides ranged from 90.6 for fenvalerate to
105.5% for propargite. Results showed that 56.1% of tomato samples contained
detectable residues and Chlorpyrifos and cypermethrin were the most detected
pesticides, while amounts of propargite, methamidofos, cypermethrin,
chlorpyrifos were the largest detected and mounted to 0.99, 0.15, 0.015, 0.012
mg/kg respectively as a median values. Residues of methamidofos in only 2
samples were above the European MRLs.,
The research work based on an economical study on sugarbeet crop in Deir
Ezzor during the period (١٩٨٠–١٩٩٦) and the prospective horizons of it
through the cultivated area, yield and total production in order to know the
extent of cultivation deve
lopment and the factors influencing this crop.
Results showed that the area under sugarbeet was unstable which negatively
reflected on the yield and production during the studied period.
However, these changes were not important statistically for the cultivated
area (non-significant regression), while the regression was significant for the
yield and production. The results also showed the presence of negative relation
between the area and productivity of this crop.
