bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

indian meal moth, plodia interpunctella hubner is one of the most important stored-product insects that are controlled by fumigants. however, the use of plant essential oils and their constituents may have the advantage over conventional fumigants in terms of low mammalian toxicity and can be used as alternatives to conventional fumigants. therefore, in this research, repellent activity of 18 p...

charcoal rot diseases of melon caused by macrophomina phaseolina is one of the most important diseases of melon occurring in regions with variable climate. reduction of yield of melon by this disease has been reported up to 100% in some of garmsar field. salinity which can cause the important trouble in plant metabolism and nutrition is present in semnan and garmsar areas. melon is susceptible ...

The present study evaluates the insecticidal activity of two essential Oil (EOs) mint (Mentha arvensis), and ajwain (Carum capyicum) against pulse beetle (Callosobruchus chinensis) (L). Contact toxicities these were evaluated using parameters lifecycle like total development period, numbers eggs laid, adult emergence longevity. Along with detoxification enzyme inhibition activities acetyl choli...

Abstract The present study was carried out to investigate the beneficial and toxicological effect of plant-based titanium dioxide nanoparticles (TiO 2 NPs) on morphophysiological attributes wheat plants under salinity stress. biogenesis accomplished by using extract Buddleja asiatica L. leaves followed characterization through UV visible spectroscopy, SEM, FTIR, EDX. NaCl salt applied in two di...

Salinity considered as significant ecological regarding the productivity of different crops different arid and semiarid areas all over the world. The most damaging things of salinity on herbal are usually related with low osmotic potential of soil solution, nutritional imbalance etc. Improving several plants usually happens under saline circumstances as a method for using saline soils which are...

increased salinity stress because of rising temperature as a result of global warming. High salinity enhances plants photorespiration and affects its physiology, but Salicornia europaea L. in Urmia Lake has adapted to grow, propagate and occupy increasingly exposed saline habitats. Plant and soil samples were collected in triplicate plots from different sites of retreated beds of Urmia Lake in ...

There is a growing interest among consumers and researchers in the globe artichoke [Cynara cardunculus L. subsp. scolymus (L.) Hegi] leaf extract due to its nutraceutical and therapeutic properties. The application of an abiotic stress such as salinity can activate the stress-signaling pathways, thus enhancing the content of valuable phytochemicals. The aim of this study was to assess the metab...
