Effect of Various Herbicides on Warm‐season Grass Weeds and Switchgrass Establishment

Crop Science, Volume 53, Issue 2, Page 666-673, March 2013., 2013
ABSTRACT Switchgrass (Panicum virgatum L.) is typically slow and difficult to establish. Field experiments evaluated switchgrass establishment and the response of warm‐season grass weeds (large crabgrass [Digitaria sanguinalis (L.) Scop.], broadleaf signalgrass [Urochloa platyphylla (Munro ex C. Wright) R.D. Webster], Johnsongrass [Sorghum halepense (L.

Efficacy of Herbicides When Spray Solution Application Is Delayed

International Journal of Agronomy, Volume 2013, Issue 1, 2013., 2013
Information is limited concerning the impact of delaying applications of pesticides after solution preparation on efficacy. Experiments were conducted to determine weed control when diclosulam, dimethenamid‐P, flumioxazin, fomesafen, imazethapyr, pendimethalin, and S‐metolachlor were applied preemergence the day of solution preparation or 3, 6, and 9 ...

Control of Conyza spp. with sequential application of glufosinate in soybean pre-sowing [PDF]

Ciência Rural, 2020
: Conyza spp. is among the main weeds reported worldwide. Due to its aggressiveness, such as high seed production and dispersion, and the growing reports of biotypes resistant to glyphosate, paraquat, and other herbicides, different control practices are

Evaluation of leaf surface structure and control of Conyza spp. by herbicides applied in soybean pre-plant burndown [PDF]

Brazilian Journal of Biology
The pre-plant burndown of Conyza spp. is a fundamental practice to mitigate weed competition with soybean. However, in light of reports of biotypes resistant to 2,4-D, the search for new options of post-emergent herbicides becomes essential.
