an experiment was conducted at ecbatan research station in hamedan in two years (1998-99) to study the effects of planting density and methods and also seed clove size on yield of hamedan garlic. the experiment was in factorial 3 x 3x 3 in randomized complete block design with three cultivation methods, three sizes of seeds and three plant densities in three replications. the data were analized...

Effect of some plant extracts against damping-off disease of some winter vegetable was studied in the net house. Seed treatment with neem leaf, garlic clove, allamonda leaf, ginger rhizome, kalijira seed, bel leaf, turmeric rhizome, katamehedi leaf and onion bulb were evaluated against damping-off, seed germination and growth characters of tomato, eggplant and chilli seedlings. All the treatmen...

BACKGROUND: Autoxidation is an irreversible reaction which occurs with the effect of oxygen in the air, and results in unpleasant taste and smell that are known as the signs of rancidity in oil. OBJECTIVES: In this study, the antioxidant potential of clove, summer savory and tarragon essential oils (EOs) in grape seed oil was evaluated. METHODS: Effects of EOs at different concentrations (0.3, ...

Antifungal activity of ethanol-water extracts of four medicinal plants, cinnamon (Cinnamomum verum Presl.), anise (Pimpinella anisum L.), black seed (Nigella sativa L.) and clove (Syzygium aromaticum L. Merr. & Perry.) was investigated against pea (Pisum sativum L.) root-rot fungus Rhizoctonia solani. In vitro antifungal activity test shown a high growth inhibition at concentration (4%) of each...

Three different concentrations of clove oil were applied to two different size groups of singhi (Heteropneustes fossilis) and lata (Channa punctatus) fish to observe the anaesthetic effect and to find an optimum dose. Two groups each consisting of 10 fish was exposed to 0.01, 0.02 and 0.03% clove oil. All fish of either size anaesthetized with 0.01% clove oil exhibited longer induction and shor...

Black mold disease caused by Aspergillus niger V. Tiegh. is the most devastating infection occurs in onions (Allium cepa L.) under field and store conditions. The use of biocontrol agents is ecofriendly approach for controlling seedborne and soilborne diseases compared to the use of toxic synthetic fungicides. This study has been designed to assess the contamination levels of onion seeds with A...

Experiments were conducted in a citrus orchard to investigate the attractiveness of 26 plant essential oils individually and in combination with a synthetic food odour lure to the Mexican fruit fly, Anastrepha ludens Loew. Anise, rose/grape seed, and tea tree oils were more attractive than unbaited traps but none approached the attractiveness of Advanced Pheromone Technologies AFF lure, a synth...

Seeds of rice were treated with Garlic (Allium sativum) clove extract @ 1:0, 1:1, 1:2 dilutions in water, allamanda (Allamanda cathartica) leaf extract @ 1:1, 1:2, 1:3 dilutions in water and Provax-200 @ 0.3% for controlling seed borne fungi, where the seed samples of three rice varieties viz. Katharee, Gutee Aus and Kalijira were collected from farmer’s storages of Bangladesh. The seed germina...
