Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity. The aim of this study was to examine whether the effects of a herbicide mixture (50% atrazine, 35% isoproturon, 15% alachlor) on single macrophyte species can be use...

A field experiment was conducted during 2015–16 and 2016–17 at Instructional Farm (Agronomy), Rajasthan College of Agriculture, Maharana Pratap University Agriculture Technology, Udaipur, Rajasthan, to evaluate the effect weed nutrient-management on quality protein maize. The consisting 9 weed-management treatments, viz. weedy check, hand-weeding 15 days after sowing (DAS) 35 DAS, tembotrione 0...

The results of seven pre-emergence herbicide screening trials involving 27 chemicals are presented. The experiments, which were conducted over a fouryear period, differed with respect to soil moisture conditions, soil type and prevailing weed flora. Special attention was directed to the control of Cyperus esculentus, C. rotundus and grasses. Mean visual assessmenlts of control of species or spe...

Several recent studies have focused on leaching pesticides from agricultural soils into surface and groundwater resources during irrigation. As a result, information about herbicide residues in water was necessary for conserving related resources. This study provided an overview of monitoring herbicides worldwide. In this scoping review, five databases were searched publications (1990 to April ...

In the present work, DNA recombination of three homologous tau class glutathione transferases (GSTUs) allowed creation a library GmGSTUs. The was activity screened for identification transferase (GST) variants with enhanced catalytic towards herbicide alachlor (2-chloro-2?,6?-diethyl-N-(methoxymethyl)acetanilide). One enzyme variant (GmGSTsf) improved and binding affinity identified explored de...

Weed control efficacy of three herbicides recently registered for use in the South African Sugar Industry is discussed and the phytotoxic effects on sugarcane are presented. Destun, with or without atrazine, is a safe pre-emergence treatment which is useful for the control of Cyperus esculentus, grasses and broadleaf weeds, while some activity on Cyperus rotundus has also been recorded. Dual + ...

The results are presented of a series of herbicide experiments conducted on two soils in Natal; a heavy clay and a light sand respectively having high and low organic matter contents. The experiments were designed to evaluate preand post-emergent herbicide treatments on the specific weeds Panicum muximum, Cyperus rotundus, C. esculentus and annual grasses. Alachlor/2,4-D was the most successful...
