A modification of the GLEAMS model was used to determine application windows which would optimise efficacy and environmental safety for herbicide application to a forest site. Herbicide/soil partition coefticients were determined using soil samples collected from the study site for two herbicides (imazapyr, K,=46, triclopyr ester, K,,=l038)andpublishedvaluesfortwootherherbicides(henarinone,K,=5...

In 2007 and 2008, field trials were carried out with different standard and drift-reducing nozzles in sugar beet, maize, chicory, Belgian endive (all herbicide applications), wheat (fungicide application) and potatoes (Haulm killing herbicide application). The effect of nozzle type (standard flat fan, low-drift flat fan, air injection), nozzle size (ISO 02, 03 and 04) and application volume on ...

Methylated seed oil (MSO) is a recommended adjuvant for the newly registered herbicide topramezone in China and also in other countries of the world, but the mechanism of MSO enhancing topramezone efficacy is still not clear. Greenhouse and laboratory experiments were conducted to determine the effects of MSO on efficacy, solution property, droplet spread and evaporation, active ingredient depo...

abstract water is the most common carier used to dilute herbicides and their application. researches had shown that water quality is an important factor in some herbicide efficacy. in order to study the effect of water hardness on 2,4-d efficacy, an experiment was carried out under controlled conditions in 2010 at the college of agriculture, ferdowsi university of mashhad. experimental treatmen...

This publication answers some common questions and provides efficacy information for all herbicide active ingredients labeled aquatic use in Florida. Written by Stephen F. Enloe, Ben Sperry, James Leary, published the UF/IFAS Agronomy Department, revised May 2022.

in order to study the effect of water hardness on sinosulforun efficacy an experiment was carried out under controlled conditions in 2010 at the college of agriculture, ferdowsi university of mashhad. treatments included herbicides doses at 6 levels (0, 200, 250, 300, 350 and 400 g.a.i ha-1), calcium carbonate concentration at 6 levels (0, 100, 300, 600, 1000 and 1500 ppm) and weeds at 2 levels...
