Tenacity Turf Safety for Postemergence Applications

, 2010
The objectives of this study were to determine turf safety with Tenacity using a boom application versus a handheld application gun. Turf safety was to be determined on both perennial ryegrass and tall fescue at one, two, and three times the labeled rate for each species, respectively, applied two times (21 days apart) during the growing season.

Residue analysis of garlic (Allium sativum L.) cloves following a postemergence application of linuron

, 1991
In a 2-yr residue study, garlic (Allium sativum L.) was grown in weed-free field plots of clay loam soil and treated at the three-leaf growth stage of the crop with postemergence applications of linuron at 2.2 kg ha−1.

Metribuzin residues in lentil following postemergence application

, 1998
In a study involving two sites in western Canada, residues of the herbicide metribuzin in lentil were monitored by gas chromatography following postemergence application at 0.28 kg a.i. ha−1.

Managing resistance: evaluating alternative herbicides for glyphosate-resistant smooth pigweed (Amaranthus hybridus) in the Republic of South Africa

Weed Technology
Herbicide resistance poses a significant challenge due to the increasing number of weeds resistant to multiple sites of action (SOAs). Recently, smooth pigweed populations resistant to glyphosate have been confirmed in the KwaZulu-Natal Province in the ...

Shattercane (Sorghum bicolor) Control in Soybeans (Glycine max) with Preplant and Postemergence Herbicides

, 1990
Field studies were established to evaluate several new herbicides for preplant incorporated and postemergence shattercane control in soybeans. Imazethapyr applied postemergence controlled shattercane most consistently.

Postemergence grass control in corn

, 2001
Many producers may be in a position where they must unexpectedly change from a preemergence-based program for grass control in corn to a postemergence program due to the recent rains.

Control of Seedling Grasses with Postemergence Grass Herbicides

, 1989
Field experiments were conducted in 1982 through 1986 to evaluate the effect of six postemergence grass herbicides, clethodim, the methyl ester of diclofop, the butyl ester of fluazifop-P, the methyl ester of haloxyfop, the methyl ester of quizalofop ...

) to Postemergence Herbicides

, 2006
Field studies were conducted to assess the tolerance of seashore paspalum (\u27Salam\u27) to postemergence (POST) herbicides in Florida in 2000 and 2001. POST applications of bentazon (2,200 g/ha), clopyralid (420 g/ha), dicamba (280 g/ha), halosulfuron (

Timing Restrictions for Postemergence Herbicides in Corn

, 2010
Several factors may delay postemergence herbicide applications. When this happens it is important to be aware of restrictions on the label based on corn size or growth stage.
