“…However, it has been banned in the European Union countries since 2007 [3]. Due to the high solubility and repeated use of paraquat in agricultural and non-agricultural areas, such as horticulture, large quantities of paraquat could penetrate surface water through runoff with damaging effects to the biota [4]. Even at low concentrations, it still could elicit deleterious effects, such as cytogenetic damage, physiological effects, and even death, to exposed non-target species [3].…”

“…Herbicides in the environment represent a potential hazard to living organisms due to their lipophilic properties, which allow bioaccumulation in biota, and their resistance to degradation (Aparecida et al, 2013;Jurado et al, 2011;Wyss et al, 2006;Ying and Williams, 2000;Yu et al, 2016). The majority of herbicide monitoring studies have focused on freshwater, such as lakes, rivers and reservoirs, with a particular focus on organochlorine compounds (Ccanccapa et al, 2016b(Ccanccapa et al, , 2016aHorak et al, 2021;Masiá et al, 2013;Miller et al, 2019;Palma et al, 2014;Papadakis et al, 2015;Tadeo et al, 2008), with a few exceptions see for example (Riascos-Flores et al, 2020;Yang et al, 2019).…”

In 2017 sewage released into Camps Bay, Cape Town was nine fold more than rainfall.• Five herbicides were found in seawater, sediments and marine biota from Camps Bay. • The chemical load in sewage was not removed by a 3 mm screen pretreatment step. • The chemical signature found in marine biota was linked to herbicides in sewage. • Dilution of sewage by seawater did not prevent bioaccumulation of herbicides.

“…Low-cost involvement in herbicidal weed management and shortage of labor during the peak period of weed control encourages farmers to use herbicide in the crop fields [1]. Continuous and excessive use of herbicides for a long time causes several negative effects on the surrounding wildlife and farmers' health [12][13][14][15]. For example, the long-term effect of Agent Orange (mixture of 2,4-D and 2,4,5-T) used in the Vietnam Wars, and the Seveso tragedy of Italy in 1976 during production of 2,4,5-T are very well known in world history [12].…”

Preliminary Reports on Comparative Weed Competitiveness of Bangladeshi Monsoon and Winter Rice Varieties under Puddled Transplanted Conditions

Weed-competitive rice cultivars, a viable tool for integrated weed management of rice-field weeds, may greatly reduce the weed pressure and excessive dependence on herbicide in controlling weeds. Based on this premise, field experiments were conducted in 2018 and 2019 during the monsoon and winter rice-growing seasons at the Agronomy Field Laboratory of Bangladesh Agricultural University, Bangladesh, to evaluate the weed competitiveness of the selected rice varieties. A total of 42 monsoon and 28 winter rice varieties from Bangladesh were evaluated under “weedy” and “weed-free” conditions in the puddled transplanted system of cultivation. The field experiments were designed with three replications in a randomized complete block design. The results revealed that weed competition greatly reduces the yield of rice, and relative yield loss was 15–68% and 20–50% in monsoon and winter season rice, respectively. The lowest relative yield losses were recorded in monsoon rice from the variety BU dhan 1 (18%) and from the winter rice BRRI hybrid dhan5 (23.7%), which exhibited high weed tolerance. The weed competitive index (WCI) greatly varied among the varieties in both seasons and the monsoon season, ranging from 0.4 to 2.8, and the highest value was recorded from the hybrid variety Dhani Gold followed by BU dhan 1. In winter season rice, the WCI varied 0.25 to 2.4 and the highest value was recorded from the variety BRRI hybrid dhan3, followed by hybrid variety Heera 6. In monsoon rice, hybrid Dhani Gold was the most productive, but BU dhan 1 was the most weed competitive variety. Among the winter-grown varieties, the hybrid Heera 6 was the most productive, and the most weed competitive. Our research confirmed a high degree of variability in weed competitiveness among the 70 Bangladeshi rice varieties tested.
