Our goal in this study was to determine the effect of dietary supplementation with Moringa oleifera (M. oleifera), and Azadirachta indica (A. indica) leaves mitigating effects chronic oxyfluorfen (OXY) toxicity on health status, expressions immune antioxidant genes, tissue morphological alterations Oreochromis niloticus. In study, we used 370 healthy O. niloticus (average weight = 25.35 ± 0.29 ...

Protoporphyrinogen oxidase, the last enzyme o f the com m on tetrapyrrole biosynthetic pathway, is inhibited by several peroxidizing com pounds resulting in accum ulation o f pho to ­ dynamic tetrapyrroles, mainly protoporphyrin IX. The inhibition characteristics o f two chemi­ cally unrelated com pounds were studied using m em brane bound pro toporphyrinogen oxidase from corn etioplasts. As sh...

We compared antioxidant responses and regulation of porphyrin metabolism in rice plants treated with oxyfluorfen (OF) or methyl viologen (MV). Plants treated with MV exhibited not only greater increases in conductivity and malondialdehyde but also a greater decline in Fv/Fm, compared to plants treated with OF. MV-treated plants had greater increases in activities of superoxide dismutase (SOD) a...

Allelopathic substances can be used to develop weed control alternatives based on natural products. The objective of this study was to compare the phytotoxic activity of aqueous leaf extracts of Rapanea umbellata with the toxicity of a synthetic herbicide on the germination and growth of weed species. The weeds species barnyard grass (Echinochloa crus-galli), wild poinsettia (Euphorbia heteroph...

Onion (Allium cepa L.) weed interference lowers bulb yield and financial return for onion growers who pay labour. During the Rabi seasons of 2011–12 2012–13, a field experiment was worked out at Horticultural College Research Institute, Dr.Y.S.R University, Venkataramanagudem, Tadepalligudem, West Godavari District, A.P to examine effects pre post emergence herbicides on economics cv.N–53. Ten ...

Sandy soils in coastal areas can be managed for peanut cultivation by minimizing the limiting factors. The study aimed to use organic soil amendments combined with weed control methods optimize peanuts' growth and yield sandy land. research was conducted area of Bengkulu, Indonesia, from September 2019 January 2020. Two experimental factors were arranged a completely randomized block design thr...

Pesticides are usually used in agriculture practice for field and post-harvest protection, whereas their prolonged persistence the environment may lead to high toxicity humans animals. Therefore, aim of this study was investigate detection different pesticide residues agricultural soil samples collected from four Egyptian governorates. A total forty were during period April June 2020. Samples e...
