Response of Soybeans to 2,4-D, Dicamba, and Picloram
Field experiments were conducted for 2 years at Urbana, Illinois, to evaluate the response of soybeans (Glycine max (L.) Merr., var. Harosoy 63) to soil and foliar applications of…
Temperature effects on germination of nine Amaranthus species
- L. Steckel, Christy L. Sprague, E. Stoller, L. Wax
- BiologyWeed science
- 1 April 2004
Germination of weed seed and time of emergence are greatly affected by temperature, and alternating temperature regimens increased total germination of all species, except Powell amaranth, which germinated similarly under both constant and alternating temperatures.
Soybean response to plant growth regulator herbicides is affected by other postemergence herbicides
- K. B. Kelley, L. Wax, A. Hager, D. Riechers
- BiologyWeed science
- 1 February 2005
Investigation of off-target exposure of soybean to plant growth regulator (PGR) herbicides determined if simultaneous exposure to PGR herbicides and labeled soybean herbicides increase PGR injury and dicamba plus diflufenzopyr caused less injury and yield loss.
A biotype of common waterhemp (Amaranthus rudis) resistant to triazine and ALS herbicides
- Matthew J. Foes, Lixin Liu, P. Tranel, L. Wax, E. Stoller
- BiologyWeed science
- 1 September 1998
Resistance to atrazine and three ALS-inhibiting herbicides in this biotype was determined and whole-plant response indicated that the Bond County common waterhemp biotype required over 1,000 times more imazethapyr relative to a susceptible biotype to reduce growth 50%.
Interference of Four Annual Weeds in Corn (Zea mays)
- T. H. Beckett, E. Stoller, L. Wax
- BiologyWeed science
- 1 November 1988
Season-long interference of shattercane, giant foxtail, common cocklebur, and common lambsquarters in corn was evaluated in the field at weed densities from 0.4 to 13.1 plants or clumps/m of corn row…
Absorption and translocation of glufosinate on four weed species
- G. Steckel, S. E. Hart, L. Wax
- BiologyWeed science
- 1 June 1997
Differential absorption and translocation of 14C-glufosinate may be contributing factors to the differential sensitivity observed between weed species.
Phytotoxic Response and Yield of Soybean (Glycine max) Varieties Treated with Sulfentrazone or Flumioxazin1
- Sarah Taylor-Lovell, L. Wax, R. Nelson
- BiologyWeed technology
- 1 March 2001
Avoidance of sensitive varieties will reduce the potential for injury and yield reduction with sulfentrazone, and maybe flumioxazin.
Occurrence and Distribution of Aphis glycines on Soybeans in Illinois in 2000 and Its Potential Control
- G. Hartman, L. Domier, P. L. Orwick
- Environmental Science
- 2001
By the end of the 2000 season, A. glycines was found in most states in the midwest, and coincidentally, it was reported for the first time in Australia (3).
Glufosinate Efficacy on Annual Weeds Is Influenced by Rate and Growth Stage
- G. Steckel, L. Wax, F. Simmons, W. H. Phillips
- BiologyWeed technology
- 1 September 1997
Control with glufosinate at 420 or 560 g/ha was most effective when applied at the 10-cm Weed height compared either to the 5- or 15-cm weed height, and common lambsquarters was the most tolerant species evaluated and was not consistently controlled acceptably.
Common waterhemp (Amaranthus rudis) interference in soybean
- A. Hager, L. Wax, E. Stoller, G. Bollero
- BiologyWeed science
- 1 September 2002
It is suggested that soybean producers should implement common waterhemp management strategies earlier than 4 wk after soybean unifoliolate leaf expansion in order to reduce the potential loss of soybean seed yield.
