“…For example, mung bean (Vigna radiata), cotton (Gossypium hirsutum), wild oat and canary grass et al In which, the sorghum (Sorghum bicolor L. Moench) and sunflower (Helianthus annuus L.) extracts for wild oat and canary grass management in wheat (Triticum aestivum). The sorghum + sunflower extracts combined of label rates of herbicides inhibited dry matter production of wild oat by up to 89% and canary grass by up to 92% [60][61][62]. Also, herbicide use can be reduced by up to 50%.…”

Objective: This paper mainly discusses the Allelopathic potential of wheat. Methods: This paper is prepared by reviewing the latest academic literatures. Result: The green revolution in the 1960s caused an increase in the demand for food. The agricultural sector and farmers tended to spend more time on the agricultural work but the crop yield was suppressed by the weeds. Hence, the usage of herbicide insecticides, fungicides and others chemicals had been increased. Although herbicides are efficient for weed controls, the continuous uses had gradually stimulated the weeds developing an effecttive resistance to the chemicals. Wheat (Triticum aestivum L.) is known as allelopathic against crops and weeds. Allelopathy of wheat (Triticum aestivum L.) has been extensively examined for its potentials in weeds management. The al-lelopathic activity of wheat has been attributed to hydroxamic acids, the related compounds and phenolic acids. Therefore, it could effectively reduce herbicide uses in order to maintain an eco-friendly environment and a cost-effective weed control.

“…Its roots are small, numerous and fibrous, penetrating into the soil to a depth of several feet. It severely competes for growth resources and significantly reduces the grain yield as its time of emergence coincides with germinating wheat crops (Malik and Singh, 1995;Afentouli and Eleftherohorinos, 1996). The most likely reasons for its wide occurrence are its resemblance with wheat at the seedling stage, similar growth period, the earlier seed dispersal, dormancy of seeds for a long period of time and, until recently, the lack of efficient and appropriate herbicides for its effective control in wheat.…”

-Understanding the weed interference with different sowing times of crop is inevitable for forecasting yield losses by weed infestation and designing sustainable weed management systems. A field experiment was carried out to evaluate the effects of sowing dates (20 th November, 10 th December) and various little seed canary grass (LCG) infestation levels (10, 20, 30 and 40 plant m -2 ) on growth and yield of wheat under semiarid conditions. Plots with two natural infestations of weeds including LCG (Unweeded control; UWC) and excluding LCG (UWC-LCG) were maintained for comparing its interference in pure stands with designated densities. A season-long weed-free (WFC) treatment was also run. All the weeds/ LCG infestation levels starting from 10 LCG plants m and UWC were comparable, however, these losses were much greater than UWC LCG. In crux, delay in sowing of wheat not only reduced the crop growth and yield but also enhanced the LCG/weed interference. Furthermore, greater competitive ability of LCG particularly for latesown wheat suggests that it should be controlled in order to provide healthy environment for crop plants.Keywords: interference, little seed canary grass, sowing time, weeds, wheat yield losses.

“…being the most troublesome grassy weeds in wheat (Triticum aestivum L.) result in yield reduction by about 30% (Bell and Nalewaja 1968;Malik and Singh 1995;Hobbs et al 1998). These weeds not only cause yield reduction but also deteriorate the produce quality by seed mixing with grains and interfere the harvest operations.…”

Environmental contamination, herbicide resistance development among weeds and health concerns due to over and misuse of synthetic herbicides has led the researchers to focus on alternative weed management strategies. Allelochemicals extracted from various plant species can act as natural weed inhibitors. In this study, allelopathic extracts from four plant species sorghum [Sorghumwere tested for their potential to inhibit the most problematic wheat (Triticum aestivum L.) weeds wild oat (Avena fatua L.) and canary grass (Phalaris minor Ritz.). Data regarding time to start germination, time to 50% germination, mean germination time, final germination percentage, germination energy, root and shoot length, number of roots, number of leaves, and seedling fresh and dry weight was recorded for both the weeds, which showed that mulberry was the most inhibitory plant species while sorghum showed least allelopathic suppression against wild oat. Mulberry extracts resulted in a complete inhibition of the wild oat germination. The allelopathic potential for different plants against wild oat was in the order: mulberry > winter cherry > barnyard grass > sorghum.Mulberry, barnyard grass and winter cherry extracts resulted in a complete inhibition of canary grass. Sorghum however exhibited least suppressive or in some cases stimulatory effects on canary grass. Plants revealing strong allelopathic potential can be utilized to derive natural herbicides for weed control.
