“…As for mechanical methods, cultivation between crop rows can effectively control both species [134,135]. Mechanical operations may need to be repeated; a general recommendation is to increase the number of interrow cultivations to increase the efficacy of mechanical weed control [126]. There is also evidence that multiple mowing operations between crop rows can also provide solutions in shattercane control [136].…”

“…Intercropping, narrow row spacing, increased seeding rates, fertilization, and irrigation management should also be investigated for the suppression of shattercane and weedy sunflower. There is evidence that such practices contribute to weed management in summer field crops where shattercane and weedy sunflower are troublesome weeds [126][127][128][129][130]. The selection of competitive hybrids and cultivars was also reported to suppress shattercane in maize and weedy sunflowers in summer legumes such as cowpea [28,64].…”

Shattercane (Sorghum bicolor (L.) Moench subsp. drummondii) and weedy sunflower (Helianthus annuus L.) are two examples of crop wild relatives (CWRs) that have become troublesome weeds in agriculture. Shattercane is a race belonging to a different subspecies than domesticated sorghum (Sorghum bicolor (L.) Moench subsp. bicolor). Weedy sunflower populations are natural hybrids between wild and domesticated sunflower (Helianthus annuus L.). Both species have key weedy characteristics, such as early seed shattering and seed dormancy, which play an important role in their success as agricultural weeds. They are widely reported as important agricultural weeds in the United States and have invaded various agricultural areas in Europe. Shattercane is very competitive to sorghum, maize (Zea mays L.), and soybean (Glycine max (L.) Merr.). Weedy sunflower causes severe yield losses in sunflower, maize, soybean, pulse crops, and industrial crops. Herbicide resistance was confirmed in populations of both species. The simultaneous presence of crops and their wild relatives in the field leads to crop–wild gene flow. Hybrids are fertile and competitive. Hybridization between herbicide-tolerant crops and wild populations creates herbicide-resistant hybrid populations. Crop rotation, false seedbed, cover crops, and competitive crop genotypes can suppress shattercane and weedy sunflower. Preventative measures are essential to avoid their spread on new agricultural lands. The development of effective weed management strategies is also essential to prevent hybridization between sorghum, sunflower, and their wild relatives and to mitigate its consequences.

“…Besides its efficient role in weed control (El-Metwally et al 2022), hoeing improves soil structure, aeration, water penetration, and the availability of some nutrients for crop plants. Also, hoeing was effective because multiple mechanical operations were performed (Gazoulis et al 2021;Kanatas and Gazoulis 2022). Consequently, sugar beet growth, agronomic traits, and quality were improved.…”

To reduce the use of herbicides in agriculture, there is an urgent need to look for cost-effective and environmentally friendly non-chemical methods to control weeds in field crops. Plant by-products could be exploited directly as plant residues or indirectly as plant extracts for weed control. Thus, the objective of this study was to evaluate the effectiveness of several plant wastes and extracts in controlling weeds of sugar beet (Beta vulgaris subsp. vulgaris) with enhancing yield and quality. Three weed control groups of twelve practices were examined. The first weed control group included three aqueous extract concentrations (15, 20, and 25%) of Plectranthus amboinicus L. The second weed control group involved six soil mulching plant materials [rice (Oryza sativa L.) straw, wheat (Triticum aestivum L.) hay, peanut (Arachis hypogaea L.) straw, mango (Mangifera indica L.) leaves, flax (Linum usitatissimum L.) meal, and soybean (Glycine max (L.) Merr.) meal], while the third group comprised of desmedipham/ethofumesate/lenacil/phenmedipham (DELP) herbicide 1.5 L ha −1 [desmedipham 70.5 g active ingredient (ai) ha −1 + ethomesufate 112.5 g ai ha −1 + lenacil 40.5 g ai ha −1 + phenmedipham 90 g ai ha −1 ], hoeing, and unweeded check. During a 2-year field trial (2019/20 and 2020/21), the 12 weed control treatments arranged in a randomized complete block design (RCBD) and replicated three times. Compared to the recommended applications (hoeing and herbicide), reduction averages of both seasons for total weeds biomass were 46.3-54.2%, 37.3-46.4%, and 23.0-34.4% due to rice straw, wheat hay, and mango leaves, respectively. Root and sugar yields of sugar beet divulged the highest values with hoeing in both seasons statistically equaling (P ≥ 0.05) rice straw and wheat hay for root yield and wheat hay for sugar yield in the first season. Except flax meal, all weeded treatments in the first season as well as mango leaves, wheat hay, peanut straw, and hoeing in the second one caused significant (P ≤ 0.05) reductions in sodium content of beet juice. Wheat hay, mango leaves, and hoeing in both seasons, in addition to rice straw, peanut straw, and herbicide in the first season, were the most efficient practices for improving sucrose % and extractable sugar %. Compared to hoeing, reductions in net return were -286.7 and -320.0 ($ ha −1 ) by percentage of 6.5 and 7.2, due to mulching soil by rice straw and wheat hay, respectively. Recycling the plant by-products such as wheat hay, rice straw, peanut straw, or mango leaves in the form of soil mulch could serve as safe and eco-friendly tools in weed control programs of sugar beet. The beneficial effect of mulching extended to enhance root and sugar yields with low impurities. Since the plant wastes are available in the farm, better revenues will be gained for sugar beet growers. Further investigations related to the use of plant extracts as natural herbicide should be performed to reach acceptable levels for weed control.

“…Pre-emergence herbicides, such as pendimethalin, trifluralin, and aclonifen, are recommended for weed control in chickpea, but these are unable to provide a broad spectrum of weed control (Singh et al, 2014;Barros et al, 2018). In Europe, where herbicide options are limited due to strict EU legislation on pesticides, recent studies have shown that aclonifen as PRE fb by POST applications of ACCase-inhibitors can provide broad spectrum weed control in chickpea especially when combined with the use of increased seeding rates (Kanatas and Gazoulis, 2022). Some studies have suggested the use of imazethapyr for broad-spectrum weed control in chickpea (Kachhadiya et al, 2009;Khope et al, 2011), but reduced efficacy in the soil and phytotoxicity to the crop restricts its wider adoption (Kumar et al, 2016).…”

Chickpea growers in Australia have no post-emergent (POST) herbicides labeled for broadleaf weed control and they rely on pre-emergent herbicides for control of broadleaf weeds. The objective of this study was to evaluate chickpea tolerance to POST application of paraquat (0, 90, 180, 360, and 540 g ai ha-1) in a randomized complete block design. Paraquat (180 g ai ha-1) applied POST (up to 10 days after crop emergence) did not injure chickpeas and reduce plant height, and biomass when compared with nontreated control. When the crop just emerged, even the highest dose of paraquat (540 g ai ha-1) did not cause any injury or reduce chickpea biomass compared with nontreated control. Moderate toxicity to chickpea at paraquat 360 or 540 g ai ha-1 was observed when applied 20 days after crop emergence. This study suggests that paraquat POST has the potential to provide broad-spectrum weed control, including broadleaf weeds at an early stage of chickpea. However, the potential for crop injury to paraquat at higher doses, especially when applied at a late stage of the crop warrants further evaluation under field conditions. The study also suggests that tank mix applications of paraquat with residual herbicides may be useful for season-long weed control in chickpea and result in improved yield. The current study warrants further evaluation of the tank-mix application of paraquat with pre-emergent herbicides for season-long weed control under field conditions.
