The insecticidal effect of six commercially available plant oils was tested against 4th larval instars of Culex pipiens. Larvae were originally collected from Meit El-Attar, Qalyubia Governorate, Egypt, and then reared in the laboratory until F1 generation. The LC50 values were 32.42, 47.17, 71.37, 83.36, 86.06, and 152.94 ppm for fenugreek (Trigonella foenum-grecum), earth almond (Cyperus escu...

We investigated the effects of three botanicals with nematicidal properties (anise-Pimpinella anisum, parsley-Petroselinum crispum, and rocket-Eruca sativa) on soil nematode community, in terms trophic structure genera composition. compared those fluopyram (synthetic nematicide) Nemagold (bionematicide). assessed role time, by sampling 15 45 days after treatments analyzing microbial phospholipi...

The pH range of 7.0 to 7.2 is recommended ensure reasonable nitrification rates in aquaponics; however, this conducive neither nitrification, a critical process that occurs at 8.0, nor plant growth. To determine the effects an aquaponic system, Swiss chard (Beta vulgaris L.), kale (Brassica oleracea mustard green juncea cilantro (Coriandrum sativum lettuce (Lactuca sativa and arugula (Eruca ves...

Due to the increase in water and energy tariffs, addition limited amount of these resources, automation irrigation can help farmers production agricultural crops. Therefore, objective this research was evaluate different managements between manual automatic arugula a protected environment, order determine productive potential cultivation vegetables. The experiment conducted randomized blocks wi...
