“…Weed density and dry matter production were reduced on a parallel basis with increasing dose of water extracts and also by combining three water extracts i.e sorghum + sunflower + mulberry instead of sorghum + sunflower (Table 1). These findings are supported by Naeem et al (2016), who reported reduction in weed dry weight with sorghum and sunflower extracts by foliar spraying. Greater decrease in total weed dry biomass by WE treatments with increasing dose showed that higher concentration of allelochemicals may be more effective for weed biomass reduction.…”

Use of synthetic herbicides to control weeds poses serious threats to sustainable agricultural production around the globe. The phytotoxic effect of different plant water extracts (i.e., sorghum, sunflower and mulberry) against weeds has been previously studied; however, their combined effects at different rates are yet to be explored. In this study, mixtures of allelopathic water extracts of sorghum + sunflower and sorghum + sunflower + mulberry were sprayed each at 12, 15, 18 and 21 L ha-1 at 40 and 55 days after sowing in wheat to control wild oats (Avena fatua), little seed canary grass (Phalaris minor), lamb’s quarters (Chenopodium album) and swine cress (Coronopus didymus). A synthetic herbicide Affinity 50 WP (Carfentrazone-ethyl 0.75% + Isoproturon 50% applied at 1000 g a.i., ha-1) and a weedy check were kept as a control treatment. The increasing order of water extract dose 12-21 L ha-1 showed substantial reduction in total weed density and their dry biomass production of both narrow and broad-leaved weeds in all the treatment combinations. Mixture of sorghum + sunflower + mulberry water extracts each at 18 L ha-1 applied at 40+55 DAS resulted in an 87.14% decrease in total weed dry matter with a 19.5% increase in grain yield of wheat and higher net benefits of Rs. 100525 with 777.5% marginal rate of return. Nonetheless, application of sorghum + sunflower water extracts each at 12 L ha-1 at 40+55 DAS was more economical than the other treatments in terms of higher marginal rate of return of 799.82%. Based on this study, it can be suggested that the use of allelopathic plant water extracts in a mixture may act as a potential weed control strategy in wheat.

“…Allelopathic plants possess a store of poisons in their body parts [2]. They compete with other species through chemical warfare by releasing biochemicals known as ''allelochemicals'' which inhibit the growth of its competitors [3]. Allelochemicals in plants act like herbicides preventing the germination and growth of the seedlings of competing species [4].…”

Search for an alternative to chemical herbicides have prompted researchers to investigate the allelopathic potential of plants, which would serve as a remedy for contamination of soil, water bodies and crops products with toxic chemical residues derived from using synthetic herbicides. The allelopathic effects of the aqueous leaf extracts of Ageratum conyzoides, Vernonia amygdalina and Artemisia annua at 0.05, 0.1, 0.2 and 0.5 (part per volume) concentrations were evaluated on seed germination, root length and height of seedlings of Lactuca sativa after 28 days in vitro. Results obtained showed significant differences P=[0.5] among the different concentrations of aqueous leaf extracts used when compared with the control in all the three parameters studied. Significant reduction in seed germination, growth of root and height of seedlings were observed in all the treatments but at varying levels from moderate to severe effects for aqueous leaf extract of A. conyzoides and A. annua respectively, while on the contrary, aqueous extracts of V. amygdalina

“…Studies have shown a great potential of allelopathy for weeds control in wheat. It is the best alternatives to the synthetic herbicides to control weeds (Bhowmik & Inderjit, 2003;Jabran et al, 2008).These outcomes are supported by Naeem et al (2016), who stated that the lessening in weed dry weight with sorghum and sunflower extracts by foliar spraying. The obtained experimental data in showed that the studied treatments evidently increased the number of tillers, plant height, spike length, and grains per spike of wheat plant as compared to control treatment.…”

The aim of present study was to investigate the allelopathic impact of sunflower water extract integrated with affinity herbicide on weed management and production of wheat variety TD-1 under field condition. The trial was carried out in a three replicated and the average plot size was kept at 3x5m (15 m2). The obtained data showed that the all the treatments considerably (P<0.05) minimized weed density, weed fresh weight, weed dry weight and weed control up to 90.33, 89.31, 89.61, 90.33% with application of sunflower water extract (1:10) @ 20 L ha-1 (One spray at 25 DAS) + Affinity 50 WP @ 0.75 kg ha-1 (One spray at 25 DAS) than control treatment. The application of sunflower water extract (1:10) @ 20 L ha-1 (One spray at 25 DAS) + Affinity 50 WP @ 0.75 kg ha-1 (One spray at 25 DAS) significantly increased number of tillers (32.34%), plant height (14.59%), spike length (27.89%), grains spike-1 (16.80%), grain weight plant-1 (47%), seed index (19.60%) and grain yield (51%) of wheat as compared with control. Overall results indicated that the sunflower water extract integrated with herbicide can be successfully used to control the narrow and broad leaves in wheat crop.
