“…The C. rotundus species shows a high competitive capacity with common bean, since it exhibits aggressive characteristics, including the release of allelopathic substances, in addition to alternative reproduction mechanisms, a high growth rate and space occupation, making it highly efficient in the use of water, light and nutrients (Tavares et al 2013, Hussain et al 2017). This species is also difficult to control, causing reductions in the stand and in a range of commercial crops.…”

“…According to Monquero et al (2009), a small amount of rattlepod on the soil surface does not inhibit the weed infestation, while larger amounts resulted in the emergence of weakened weeds, with yellowing, necrosis and deformed leaves, likely due to physical and/or chemical effects. The small amount of rattlepod used in the present study likely resulted in the inefficient control of weed infestation, especially C. rotundus, since it propagates aggressively (Panozzo et al 2009, Hussain et al 2017). Thus, a large amount of rattlepod exhibits an allelopathic effect, which is the inhibitory or stimulating effect of a plant on other species, resulting from the release of chemical substances into the environment and contributing to reduce the weed population (Scholberg et al 2006).…”

More efficient weed control managements can be achieved through different strategies, given that the population of these plants changes according to the system used. This study aimed at assessing solarization methods associated with different mulches for weed control in the cowpea crop. The methods used were soil solarization, with plastic sheeting and with solar collector, associated with the following mulches: castor bean, rattlepod and spontaneous vegetation. Weed phytosociology was calculated by frequency, density and abundance. The most infesting families were Asteraceae, Poaceae and Amaranthaceae. The species with the highest frequency, density and abundance in the treatments without mulching was Cyperus rotundus, while Bidens spp. occurred only in non-solarized soil and without mulching. The largest number of weeds was found in the treatments without mulching in non-solarized soil or soil solarized with plastic sheeting, the latter being less efficient than the solar collector. Mulching inhibits the weed infestation in cowpea crops, irrespective of soil solarization. However, rattlepod as mulch is more efficient in the solarization with plastic sheeting than with a solar collector.

“…Purple nutsedge (Cyperus rotundus L.) is a perennial weed with detrimental impact on agriculture and is widely spread throughout the world (Holm et al 1991;Horowitz 1992;Webster and Grey, 2014). Purple nutsedge reproduces by vegetative propagation using basal bulbs and tubers to proliferate into many rhizomes, resulting in populations to grow rapidly and causing great loss in agricultural yields (Nishimoto 2001;Hussain et al 2017). Studies have reported yield reduction up to 80% in soybean (Moenandir 1993;Hendrival et al 2014;Yadav et al 2017) and 97% in rice (Arunbabu and Jena 2018).…”

“…Allelopathy refers to the harmful effects of secondary metabolites produced by plants on the growth and development of other organisms (Hussain et al 2017). A vast number of researches have reported Asteraceae plants to be a source of allelochemical compounds, such as phenolic acids and terpenes (Batish et al 2007;Khan and Khan 2010;Shafique et al 2011;Arora et al 2015;Wichittrakarn 2015).…”

Abstract. Respatie. D. W, Yudono P, Purwantoro A, Trisyono Y.A. 2019. The potential of Cosmos sulphureus flower extract as a bioherbicide for Cyperus rotundus. Biodiversitas 20: 3568-3574. Cosmos (Cosmos sulphureus Cav.) flower is recognized as natural source of bioherbicide compounds for several weeds. The purple nutsedge (Cyperus rotundus L.) is an important weed, and this research was aimed to determine the effects of cosmos flower extract on this weed. Dried cosmos flowers were threshed and extracted using maceration method with 70% alcohol. The experiment was conducted in the greenhouse using a completely randomized design (CRD) with three replications. Purple nutsedge tubers were planted in polybags and treated with cosmos flower extract applicated once to three times with 300 mL polybag-1 at the concentration of 40%. Different levels of inhibitions on purple nutsedge growth were observed at 30 and 60 days after sowing (DAS) due to the presence of gallic acid in the extract. Growth parameters for purple nutsedge were analyzed using Analysis of Variance (ANOVA) and followed by Least Significant Differences (LSD) at α=0.05. Significant reductions in the number of mother shoots, daughter shoots, and roots, length of mother leaves, length of rhizomes, root, and total leaf area of the purple nutsedge treated with the cosmos flower extract at 30 DAS compared to those in the control. A significant reduction was also observed in foliage dry weight, underground organs dry weight, and total dry weight of purple nutsedge. The three application times yielded maximum inhibition. In addition, these treatments reduced N, P, and K content, chlorophyll content, and photosynthesis rates at 30 DAS. These results suggest that cosmos flower extract has the potential for controlling purple nutsedge.

“…In addition, herbicides produced from chemical synthesis cannot be used in organic farming, which makes weed control one of the major challenges of this cropping system (Gruber and Chaupein, 2009). In the last decades, a great effort has been devoted in the search for bio-herbicides with the potential to be used in organic agriculture (Pacanoski, 2011;Bailey et al, 2013;Mupondwa et al, 2015;Tigre et al, 2015;Hussain et al, 2017). However, the number of bio-herbicides on the market is limited and represents less than 10% among biopesticides (Cordeau et al, 2016).…”

Weeds reduce crop yields and require annual measures of control, although they can provide important ecological benefits. In this work, the efficacy was tested of an ecological fertilizer with herbicidal properties (Bioscrop Herbitec®) which in high concentrations (10-15%) can have a similar effect to a contact herbicide. The composition of the product is 6.0 % of water-soluble potassium oxide, 54.7 % of organic acids and 39.3 % of dispersants and diluents. The product was tested in six field trials during two years, which included two vineyards and two olive orchards and winter and spring vegetation. In each experiment three treatments were imposed, being the product applied at the concentrations of 10% and 15% and a non-treated control. In treated plots, the entire ground surface (rows and inter-rows) was sprayed. The evaluation of the effect of the treatments on vegetation was assessed by the pin point and grid methods which consisted of determining the percentage of damaged and not damaged vegetation and bare soil. The production of dry biomass of weeds was also evaluated as a measure of the persistence of the damage on vegetation. The floristic composition of the stands was also recorded to evaluate the specific susceptibility of the weeds to the different treatments. The results showed that the product severely damaged the vegetation, and the effect persisted for more than a month. The application of the product caused a severe reduction in the aboveground biomass while keeping the soil protected, showing a useful compromise between the reduction in weed competition and the maintenance of ground cover. Some species were severely damaged while others seemed to have benefited in relative terms, suggesting that the effectiveness of the product will be dependent on the weed species present.
