“…Spraying imazethapyr and lactofen resulted in dry matter reductions of roots at the V4 stage (Table 1), except for the herbicide lactofen at the V2 stage, which was similar to the control treatment. Parsa et al (2013) also reported a dry matter reduction in the root system of different soybean cultivars submitted to imazethapyr spraying at the recommended dose, which supports the results found in this work.…”

“…The impacts of lactofen on the activity of N 2 -fixing bacteria in soybean plants were not found in literature. As for imazethapyr, Parsa et al (2013) reported harmful effects on Bradyrhizobium japonicum strains, with a reduction in the number and diameter of nodules in plants treated with this herbicide.…”

“…The use of herbicides is also a common and very important practice for the cultivation of soybean, in order to guarantee high yields through the effective control of weeds. However, the toxicity of these herbicides to the microbial soil inhabitants that make symbiotic interactions can be harmful to nodulation and nitrogen fixation (Parsa et al, 2013, Zhang et al, 2013, Wu et al, 2014. For example, there is imazethapyr (ALS inhibitor), which produces deleterious effects on Bradyrhizobium japonicum strains, reducing the number and diameter of nodules (Parsa et al, 2013).…”

This research aimed at studying the action of the herbicides imazethapyr and lactofen on the root system and rhizobium/plant interaction, when they are sprayed at two phenological development stages of soybean cultivars under different soil water management. The soybean cultivars MG/BR 46 Conquista (conventional) and BRS Valiosa (RR) were submitted to three minimum soil water potential (Ψs): -0.03; -0.07 and -0.5 MPa at the V2 and V4 phenological stages. The herbicides imazethapyr at the rate (100 g a.i. ha-1) and lactofen at the rate (180 g a.i. ha-1) were sprayed 10 days after the start of water restrictions. Twenty-one days after the application of the herbicides, root dry matter and root nodulation were evaluated. The BRS Valiosa (RR) soybean cultivar presented better nodule formation and a more efficient and more adapted root system to support moderate drought stress conditions (-0.07 MPa). The MG/BR 46 Conquista (conventional) soybean cultivar presented lower the root system growth when submitted to the spraying of imazethapyr and lactofen. The activity of N2-fixating bacteria was affected by the spraying of the herbicides imazethapyr and lactofen.

“…For example, POST applied haloxyfop-p-methyl (0.304 kg a.i. ha -1 ), combined with an adjuvant Adigor Ò (0.5%), provided 95% control of S. halepense in soybean (Parsa et al 2013). These integrated approaches can reduce herbicide requirements, and hence decrease herbicide costs and inputs by 27 and 64%, respectively, without affecting crop yield (Nosratti et al 2007).…”

Eco-biology, impact, and management of Sorghum halepense (L.) Pers.

et al. 2017

Sorghum halepense (L.) Pers. is ranked among the worst and extensively disseminated weed species. It is emerging as a potential menace for agroecosystems in 53 different countries across the world. This weed is adapted to warmer regions and is native to Mediterranean areas of Africa, Asia, and Europe. In the mid-1900s, cultivation of this weed species as a potential forage crop resulted in its escape from crop fields and invasion of agricultural and natural areas, but in some European countries, it has been introduced deliberately (e.g., as contamination of seeds and soil). S. halepense interferes with economically important agronomic and horticultural crops and cause 57-88% yield losses. Herbicide tolerance, diverse propagation mechanisms, rapid development, and strong competitiveness are key attributes in its invasion. Conventional management approaches are limited in their scope to control this weed due to its rapid vegetative growth and increasing herbicidal tolerance. Integration of chemical methods with cultural or mechanical approaches is important for restricting its future spread to non-infested areas. This review provides insights into the invasion mechanisms of S. halepense, which will help in its

“…Haloxyfop-P-methyl controls weeds by competitive binding to acetyl-CoA-carboxylase (ACC), which is an important enzyme in the biosynthesis of fatty acids (Hijano et al, 2013). However, application of haloxyfop-P-methyl at recommended dose may cause injury to some soybean cultivars (Parsa et al, 2013). It also has been reported that strong inhibition of biosynthesis of fatty acids was observed in wheat and maize treated by haloxyfop (Banas et al, 2012).…”

Herbicide safener, a diverse group of chemicals, is an important tool used to protect plants from herbicidal injury. With the aim of decreasing drift injury of haloxyfop-P-methyl to sensitive plants, the protective effect of four safeners (R-28725, 3-dichloroacetyl oxazolidine and its two optical isomers) was evaluated. Physiological and biochemical tests were conducted under laboratory conditions in Northeast Agricultural University, China, by using seed treatment with safener and soil treatment with haloxyfop-P-methyl, respectively. The maize seeds treated with these safeners were safe from haloxyfop-P-methyl treatment. A positive correlation between growth level and endogenous glutathione (GSH) content, glutathione S-transferases (GST) activity was observed in this research. Enhancement of GSH content, GST activity and affinity of GST to 1-chloro-2,4-dinitrobenzene (CDNB) in maize treated by R-28725 was maximum. However, the detoxification of herbicide was not accompanied by the increase of acetyl-CoA-carboxylase (ACC) activity in maize.
