In vitro evaluation of plant extracts, bio-agents and fungicides against Purple blotch and Stemphylium blight of onion

Eight plant extracts, bio agents and fungicides were evaluated in in vitro conditions against purple blotch and Stemphylium blight of onion caused by Alternaria porri and Stemphylium vesicarium. Among the plant extracts, clove extracts of Allium sativum at 10% resulted in maximum inhibition of growth (58.05 and 57.31%) of A. porri and S....

Comparison of total phenolic content and antioxidant activities of freeze-dried commercial and fresh fruit juices

Fruits contain various natural antioxidants and secondary metabolites which play an important role in human health. Fruit juices have been proposed as a convenient substitute for fresh fruit. In this study, the total phenolic content and antioxidant activity of various freeze-dried fresh fruit blends or fruit juices (Apple, lime, guava, mango, orange) were compared. Total phenolic content of the extracts was determined...

Phytochemical screening and insecticidal activity of three plants from Chenopodiaceae family

Natural insecticides have been used for pest control, offering an effective alternative to synthetic pesticides. The insecticidal activity of three species belonging to family Chenopodiaceae (Atriplex farinosa Forssk, A. nummularia Lindl. and Haloxylon salicornicum (Moq.) Bunge ex Boiss.) were investigated. Plant material from each species was ground and each extract was subjected to...

Phenolic acids and total antioxidant activity in Ocimum basilicum L. grown under Na2SO4 medium

The antioxidant activity of two basil cvs (Ocimum basilicum L. cvs. Genovese and Fine),grown for 15 and 30 days in the absence or in the presence of 25 mM sodium sulphate(Na2SO4), was measured. At the same time, phenolic acid contents of the same plant materials were determined to evaluate their probable contribution to the total antioxidant capacity. The results showed that Genovese cultivar was a...
