Essential oils (EOs) and Plant extracts (PEs) are gaining attention as eco-friendly alternatives to synthetic fungicides for the management of soil-borne fungi related root rot wilt marigolds. Here, EOs Cinnamomum zeylanicum (cinnamon), Mentha piperita (peppermint), Syzygium aromaticum (clove), Thymus vulgaris (thyme), PEs Cymbopogon citratus (lemongrass), Lantana camara (lantana), Ocimum basil...

Marigold botanically identifies as Tagetes (Compositae) genus is an ethnobotanically known drug, used from ancient times in the Indian system of Medicine for the treatment of rheumatism, cold, bronchitis, eye diseases, ulcers etc. Tagetes species, commonly known as marigold, are grown as ornamental plants and thrive in varied agro-climates. The genus has been recognized as a potential source of...

intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92. A pot experiment was carried out in south Florida to elucidate suppressive or antagonistic effects of several cover crops grown in rotation on soil nematode populations. The crops were two marigolds, Tagetes patula L. ‘Dwarf Double French Mix’ (MDF), and Tagetes pat...

The effects of natural dietary carotenoid supplementation of the maternal diet (tomato powder and marigold extract) on transfer to the egg yolk and on the development of the antioxidant system of the young quail liver in early postnatal life were investigated. Sixty Japanese quail (Coturnix coturnix japonica) were allocated to four treatment groups, each with three replicates consisting of four...

Both earthworms and symbiotic arbuscular mycorrhizal fungi (AMF) often co-occurr in ecosystems, however very little is known on their interrelationships. Here we tested to what extent earthworms (Annelida) or AMF (Glomales) separately or in combination affect the growth of the pharmaceutical plant species, pot marigold (Calendula officinalis, Asteraceae). We conducted a greenhouse experiment us...

Several potential cover crops were evaluated for their susceptibility to Meloidogyne arenaria race 1, M. incognita race 1, and M. javanica in a series of five greenhouse experiments. No galls or egg masses were observed on roots of castor (Ricinus communis), cowpea (Vigna unguiculata cv. Iron Clay), crotalaria (Crotalaria spectabilis), or American jointvetch (Aeschynomene americana). Occasional...

Phytoplasmas associated with cucumber phyllody (CuP) and squash phyllody (SqP) in Yazd province of Iran were characterized by molecular analyses and biological studies. Orosius albicinctus leafhoppers testing positive for phytoplasma presence by polymerase chain reaction (PCR) successfully transmitted CuP and SqP phytoplasmas to healthy cucumber and squash plants. The phytoplasmas were also tra...
