Cressa cretica (Shuwwayl) is a halophytic that belongs to Convolvulaceae, naturally grown in the Middle East including Iraq. Traditionally the plant is used as a paste for sore treatment, also it is used for fever, jaundice, and other illness. Regarding nonclinical use it is used as goat, sheep, and camel feed also as an oil source. Flavonoids including quercetin, kamepferol, apigenin, and their glycosides, phenolic acid as chlorogenic acid, and phytosterols mainly ?–sitosterol were the most important phytochemicals that were detected in this halophyte. Crude ethanolic, methanolic extracts and ethyl acetate fraction of the areal parts were used in clinical studies and demonstrated various effects as hepatoprotective, cytotoxic, and genotoxic effect. In molecular docking studies, 3,5-dicaffeoylquinic acid showed antiviral effect vs SARS-CoV-2 (sever acute respiratory syndrome corona virus-2). The purpose of this review was to clarify and discuss all aspects regarding Cressa cretica.

“…A detailed study of the floristic composition and vegetation analysis of four habitats in Suez Governorate was provided by Abd El-Hamid (2017). Al-Sherif et al (2018) determined the weed flora composition and its distribution through different habitats in Fayoum region. Mahgoub (2019) gave a comparative view about the impact of the prevailing climate, soil type, crop type, crop sustainability and urbanization on species distribution and weed community structure in Isthmus of Suez and adjoining farmland east Nile delta region.…”

One significant biotic barrier to crop production is weeds. The present study aims to analyze the weed vegetation associated with cultivated crops in the newly reclaimed lands in the three Suez Canal governorates (Ismailia, Suez and Port-Said). A total of 148 weed species (96 annuals and 52 perennials) belonging to 110 genera and 26 families were recorded. The most species-rich families were Poaceae, Asteraceae, Amaranthaceae and Fabaceae. Therophytes and Chamaephytes were the most prevailing lifeforms. The chorological analysis of the vegetation revealed that Cosmopolitan, Saharo-Sindian and Mediterranean chorotypes either pure or extended into other regions form the major component of the floristic structure. The application of TWINSPAN classification technique yielded four vegetation groups. These groups were dominated by Schismus barbatus, Senecio glaucus, Cynodon dactylon and Melilotus indicus. Biodiversity indices (species richness, Shannon's index, Simpson's index and Evenness index) indicated that vegetation group B was the most diversified among other groups. The ordination of stands in the study area by using DECORANA program showed that the vegetation groups obtained by TWINSAPAN are distinguishable and have a clear-cut pattern of segregation on the ordination diagrams.Canonical Correspondence Analysis (CCA) indicated that soil texture, total nitrogen, calcium, magnesium, potassium, sulphates, electrical conductivity and organic matter were the main soil parameters which determined the distribution of weed vegetation in the study area.

“…In India, P. glabrum is abundant throughout the year, while the emergence and development of R. dentatus is analogous to that of wheat and mustard in India and Pakistan. Rumex dentatus is abundant in Europe, Asia, Mediterranean region and Egypt, while P. glabrum is present in India, Sri Lanka, Nepal, Afghanistan, South Japan, Malaysia, South China and Africa (Hadjichambis et al ., 2008; Elzaawely and Tawata, 2012; Al-Sherif et al ., 2018). Wheat is one of the major cereal crops in India and is cultivated ca.…”

Two Polygonaceae weeds, Rumex dentatus L. and Polygonum glabrum Willd. are abundant in wheat- and rice-fields, respectively, in India. Galerucella placida Baly (Coleoptera: Chrysomelidae) is a biocontrol agent of these two weeds. The importance of long-chain alkanes and free fatty acids present in leaf surface waxes of these weeds was assessed as short-range attractant and ovipositional stimulant in G. placida females. Extraction, TLC, GC-MS and GC-FID analyses demonstrated 19 n-alkanes from n-C14 to n-C35 and 14 free fatty acids from C12:0 to C22:0 in leaf surface waxes. Hentriacontane was predominant among alkanes in both weeds, while oleic acid and docosanoic acid were predominant among free fatty acids in R. dentatus and P. glabrum, respectively. Females of G. placida were attracted toward one leaf equivalent surface wax of both weeds against the control solvent (petroleum ether) in a short Y-tube olfactometer bioassay. But, the insect could not differentiate between one leaf equivalent surface wax of R. dentatus and P. glabrum, indicating that both weed leaves were equally attractive in females. A synthetic blend of either 2.44, 35.57 and 23.58 μg ml−1 of octadecane, heptacosane and nonacosane, respectively, resembling the amounts present in one leaf equivalent surface wax of R. dentatus or 4.08, 19.54 and 23.58 μg ml−1 of octadecane, palmitoleic acid and docosanoic acid, respectively, resembling the amounts present in one leaf equivalent surface wax of P. glabrum acted as short-range attractant and ovipositional stimulant in G. placida. These results could be a basis for host plant specificity of the biocontrol agent.
