1,1'-Dimethyl-4,4'-bipyridinium dichloride (methyl viologen; paraquat), an herbicide that causes depletion of NADPH and generates excessive reactive oxygen species (ROS) in vivo, has been used to screen for ROS-sensitive Drosophila mutants. One mutant so isolated, named quiver(1) (qvr(1)), has a leg-shaking phenotype. Mutants of the Shaker (Sh), Hyperkinetic (Hk), and ether a go-go (eag) genes,...

After the discovery that 1-methyl 4-phenyl 1,2,3,6tetrahydropyridine (MPTP) induced a parkinsonian syndrome in individuals who inadvertently injected the by-product of illicit drug manufacturing (Langston et al., 1983; Ramachandiran et al., 2007; Richardson et al., 2005), numerous investigators made the observation that the herbicide paraquat (N,N#dimethyl-4,4#-bipyridinium dichloride, CAS# 191...

The main objective of the experiment is aimed to examine impact paraquat dichloride on body weights adult male Wistar rats as well in their haematological tissues. total number was 48 and divided into 4 groups 12 each. 1st group (Test 1) served control. other three experimental which administered. are 2nd 2), 3rd 3) 4th 4) received doses 10 mg/kg b.wt/per oral/day, 20 oral/day 40 respectively. ...

A field experiment was conducted at the Pulse Research Centre of Bangladesh Agricultural Research Institute, Ishurdi, Pabna during Kharif-II season of 2010 to evaluate the efficacy of five herbicides for controlling weeds associated with mungbean (BARI Mung-6). The five herbicides such were: Paraxon (27.6% WV Paraquat dichloride salt), M-clor 5G (Butaclor), Topstar 40 WP (40% Oxadiargyl), Hamme...

Potato (Solanum tuberosum L.) is the world’s leading vegetable crop and is grown in 79% of the world countries [1]. It is an economically important staple food in both developed and developing countries because of its high yield potential and rich nutritive values. India is the second largest potato producing country in the world after China [2]. With annual production of 37.3 million tonnes fr...

A field experiment was conducted during 2018-19 to study weed diversity and their management by using broad spectrum herbicide. The laid out in randomized complete block design with three replications. vegetation analysis done before herbicide treatment. Herbicides evaluated were glufosinate-ammonium 13.5% SL at 375, 495 615 g a.i./ha, diuron 80% WP 1600 a.i./ha paraquat dichloride 24% 500 alon...

The electrochemical behavior of the herbicide paraquat was studied for an electrode modified with a PANI/CaraiaGum composite by means of square wave voltammetry. It was obtained an analytical curve in the range of 1x10 -7 to 3x10 -4 molL -1 using the following parameters: frequency of 20 Hz, wave amplitude of 80 mV, scan increment of 5 mV, an acetate buffer (pH=10) as electrolyte solution and p...
