“…Javaid et al (2013) found that metabolites of various Trichoderma species prepared in M-1-D medium showed greater herbicidal activity against germination and growth of parthenium than those prepared in malt extract broth. Similar variable herbicidal activity was found in metabolites of Drechslera species prepared in different growth media against Rumex dentatus (Akbar andJavaid, 2010, 2013). Recently, Javaid et al (2017) reported that metabolites of Alternaria japonica prepared in malt extract broth and potato dextrose broth showed different herbicidal activities against parthenium.…”

“…However, synthetic herbicides create environmental problems and some resistance of weeds against herbicides. Thus, in this situation there has been a need of safe and eco-friendly weedmanagement strategies (Teeraraka et al, 2010;Akbar et al, 2014). In recent years, some studies have been carried out to control parthenium and other weeds in laboratory, green houses, and under filed conditions by fungal metabolites (Javaid, 2010;Akbar and Javaid, 2015).…”

Herbicidal Activity of Aspergillus niger Metabolites Against Parthenium Weed

2018

Metabolites of Aspergillus niger, prepared in malt extract (ME) broth and potato dextrose (PD) broth, were evaluated for their herbicidal activity against a noxious parthenium weed (Parthenium hysterophorus). In laboratory assays, original (X) and diluted (½ X) fungal metabolites significantly reduced germination and seedling growth of weed. However, metabolites prepared in ME broth proved to have greater herbicidal activity than metabolites prepared in other growth medium. Original metabolites prepared in ME broth have completely hinder the germination of parthenium seeds; while those prepared in PD broth have reduced germination by 89% over control. In pot trials, one-week, two-week and three-week-old parthenium seedlings were sprayed three times with original and concentrated (2X) metabolites of A. niger prepared in ME broth. Plants were harvested after 40 days of sowing. One-week treatment plants were most susceptible to fungal metabolites spray, followed by two-week and three-week treatment plants, respectively. Original and concentrated metabolites have significantly reduced shoot biomass of one-week-old plants by 57% and 68%, and root biomass by 50% and 75%, respectively. The present study has come to the conclusion that A. niger metabolites prepared in ME broth can effectively control germination and growth of parthenium.

“…One of these alternative approaches is the use of fungal metabolites either in crude form or as purified compounds (Javaid et al, 2013;Akbar and Javaid, 2013). There are various reports in which fungal metabolites successfully seized the growth of various weeds including parthenium (Javaid and Ali, 2011;Javaid et al, 2017), through the production of antifungal compounds namely holadysenterine (Akbar et al, 2014), drazepinone (Evidente et al, 2005), and ophiobolin A (Evidente et al, 2006). The herbicidal activity of various fungal species including Trichoderma, Dreschlera, Alternaria and Aspergillus against parthenium has been reported in previous literature Javaid, 2012, 2013;Javaid et al, 2013Javaid et al, , 2017Bashir et al, 2018).…”

ISOLATION AND CHARACTERIZATION OF NATURAL HERBICIDAL COMPOUND FROM Drechslera rostrata

-In agriculture, weeds have inevitable importance because of reducing the crop growth and also affecting food quality. Although, synthetic herbicides are available to combat these weeds but during recent years there is a trend of using ecofriendly herbicides extracted from natural resources. Present investigation is a continuity of the research, which reported a natural herbicidal compound named as Ophiobolin A from a fungus, Drechslera rostrata. The fungus was incubated in a growth medium of known composition (minimal medium) up to 28 days and its metabolites were extracted with organic solvents. The compound showing bioactivity was purified with the help of Reversed Phase High Performance Liquid Chromatography (RPHPLC) and identified with the help of Spectroscopic techniques viz. Mass Spectroscopy (MS) (LRESIMS and HRESIMS) and Nuclear Magnetic Resonance Spectroscopy (NMR). The purified compound caused death of superficial leaf cells of Chenopodium album, a noxious weed of wheat. Present investigation concludes that the identified compound could be used as structural analogue alternative to synthetic herbicides to synthesize natural herbicides.Keywords: Chenopodium album, natural herbicide, metabolites. RESUMO -Na agricultura, as plantas daninhas têm uma importância fundamental, por reduzirem o crescimento das culturas e também alterarem a qualidade da comida. Apesar de os herbicidas sintéticos estarem à disposição para combatê-las, nos últimos anos tem-se observado a tendência de usar herbicidas sustentáveis
