| Abstract | ||
| The influence of each pesticide Mikal (fungicide) & Dimethoate (insecticide) on certain components of cucumber plants Beth Alpha group F1 hybrids were studied on chlorophyll and carotenoids content in leaves, also on ascorbic acid content in fruits. Experiments were carried out in greenhouse farm at Nubaria city during winter - spring and repeated for two seasons. Three cucumber Cucumis stavius (L) varieties F1 hybrids (Katia, Nile and Passandra) were supplied with three rates of irrigation and three fertilization levels in equal plots of 6 m2 with three replicates of each treatment. The maximum and minimum temperature and relative humidity were recorded during the experimental time. The data showed that Katia variety of cucumber gave the highest total product yield under greenhouse conditions, half rate of fertilizer and irrigation level, however there is no significant effect of different varieties on their susceptibility to pests and diseases, increasing of fertilizer level increase chlorophyll content, and carotenoid, However, Mikal treatment decrease chlorophyll content and carotenoid. Ascorbic acid content does not affect by irrigation level but it decreased when increase fertilization level. The residue level of dimethoate on cucumber fruits after three days of spray application was below tolerant level. There was a metabolite for dimethoate pesticide after 3 days, finally the dimethoate and its metabolites concentration become undetectable after 7 days of treatment. | ||
