Greenhouse and field studies were conducted in 2007 and 2008 to investigate possible multiple-resistance of horseweed to paraquat and glyphosate, and to evaluate the effect of the addition of metribuzin to paraquat on control of paraquat-resistant horseweed. Results indicated that the GR50 (herbicide dose required to cause a 50% reduction in plant growth) value for the susceptible population S1...

Mutations in the secondary quinone electron acceptor (QB) pocket of the D1 protein conferring a modification on the donor side of photosystem II (PSII) have been characterized by gene cloning and sequencing in two metribuzin-resistant mutants of Synechocystis PCC 6714. The mutations induce different herbicide resistances: in M30, a point mutation at the codon 248, isoleucine to threonine, resul...

A laboratory experiment was conducted by using three herbicides, two from dinitroaniline group and one from thiocarbamate group to know their degree of downward movement (leachability) through soil columns and their contribution in ground water contamination. Soil columns were loaded with Pendimethalin, Benthiocarb and Oryzalin at doses of 10.0, 10.0 and 7.7 kg/ha, respectively. After 30 days s...

abstract limited number of herbicides are used to control weeds in soybean, which has herbicides resistance in consequence, so cultural weed management can be used in order to evaluate the effect of planting dates of soybean cultivars on weed management an experiment was conducted in randomized complete block design (rcbd) with four replications and with strip plot arrangement in sari. two plan...

Nanotechnology operates at the nanoscale, offering precise manipulation and enhancing materials, applications, performance across various domains. It holds promise in addressing weed-related losses, with nanofibers emerging as a noteworthy option among diverse nano-formulations. The research conducted Centre for Agricultural Nanotechnology, TNAU, Coimbatore focuses on crafting pendimethalin-loa...

We found that biofilms drive the removal of bentazone, metazachlor and metribuzin from water through rapid mineralization these herbicides, rather than by their sorption accumulation.

ABSTRACT- To compare the effects of six types of non-living mulches (wheat straw, sawdust, coco peat, peat moss, transparent and black plastic) with metribuzin on yield and yield components of tomato cv "CH" and the weed control efficiency, a study was conducted in a randomized complete block design with three replications at School of Agriculture, Shiraz University in 2012. Plots without mulch...
