Background: Aflatoxin B1 is a secondary toxic metabolite produced by several aspergillus species. This study was conducted to determine the presence of aflatoxin in tomato paste samples. Methods: A total of 30 tomato pastes were analyzed for Aflatoxin B1 contamination via HPLC-FLD. Analyte extraction was done by dispersive liquid-liquid microextraction. Results: The limit of detection (LOD) and...

The spread and outbreaks of phytophagous pests are often associated with global warming. In addition to economic interest, these species may be interest in terms biological indication climate changes. this context, we considered the locust digitate leafminer Parectopa robiniella Clemens, 1863 (Lepidoptera: Gracillariidae). This phytophage was first discovered Europe 1970 near Milano Italy. Sinc...

in order to evaluate of abscisic acid, paclobutrazol and uniconazole hormones effects on the egyptian broomrape (orobanche aegyptiaca. pers) control and growth indexes of tomato (lycopersicon esculentum mill.), a glasshouse experiment was conducted in crd design with four replications. treatments consisted of abscisic acid in 4 levels (1, 3, 5 and 7 mm), paclobutrazol in 2 levels (0.1 and 0.01 ...
