“…Such a phenomenon significantly depended on the concentration and duration of exposure (Rajendiran, 2005). Several workers have detected and reported various allelochemicals such as terpenes, phytosterol, and phenolics in Parthenium (Batish et al, 2002 andKil et al, 2006). Besides the inhibitory impact of Parthenium leaf-leachate on seed germination and seedling growth, its growth retardatory impact on the target crop V. unguiculata was evinced in this study.…”

World’s one of the most invasive weeds Parthenium hysterophorus L. (Congress grass, family Asteraceae), native to South America, is the most aggressive alien weed in India. The present study aimed to determine the growth stage (early, intermediate and mature) of this weed which was most detrimental to the growth of adjoining crop plants. Impacts of leaf-leachate concentrations (0.5%, 1% and 2%) prepared from leaves at different growth stages of P. hysterophorus were investigated on seed germination and growth of crop Vigna unguiculata. The germination percentage, shoot length, number of leaves, pods, seeds and total biomass of the crop plants significantly declined with increasing concentration of the Parthenium leaf-leachate (maximum at 2%w/v) at all growth stages. However, the leaf-leachate from the leaves of P. hysterophorus at the early growth stage showed the highest detrimental impact on the crop V. unguiculata, followed by intermediate and mature growth stages. Total phenolic content, antioxidant activity and enzymatic were highest in leaves of P. hysterophorus at the early growth stage. In conclusion, the early growth stage of this noxious weed evidently being most detrimental to the growth of adjoining crop plants, suggests Parthenium’s early growth-centric management implication.

Marigold (Tagetes spp.) is one of the most popular flower crop commercially exploited for multipurpose use. Apart from great demand of marigold flowers, the plants use in phytoremediation and allelopathic effect has been greatly exploited. Marigolds can be used against plant parasitic nematodes as a cover crop in rotation, as an intercrop, or as a crop residue amendment. Successful use of marigold as trap crop is well on record whereas its use as potential natural herbicide needs to be explored. Essential oils obtained from marigold possess antibacterial and antifungal properties and are widely used in perfumery industries, as insect repellent and as flavor component. Its extracts can be explored as alternative natural insecticides towards the stored products. Use of marigold for its medicinal value for curing various diseases has been well documented. Carotenoids extracted from flowers are being used commercially in pharmaceuticals. Marigold extract also finds application in coloring foods and various dairy products. Marigold petals are used as additives for poultry feed, as they provide bright colors in egg yolks, skin and fatty tissues and also as emulsifying gum. Silver and gold nanoparticles have been synthesized from marigold for antimicrobial activity. This review paper discusses the research undertaken for various uses of marigold plant worldwide.

“…Not only does it have excellent medicinal properties, but it also has been found to have nematicidal and antimicrobial (Tereschuk et al, 1997;Tomova et al, 2005), effects, and can be used in repellents for mosquitoes, ticks and mites (Green et al, 1991;López et al, 2011;Okoth, 1973;Perich et al, 1994;Wanzala et al, 2014;Wanzala and Ogoma, 2013), as well as in insecticides against family Psychodidae and vectors of diseases such as leishmaniasis (Dinesh et al, 2014). It was even reported that their aqueous extracts can inhibit the germination of some species, such as Lotus corniculata and Lactuca sativa (Kil et al, 2002;Meissner et al, 1986).…”
