CHEMICAL OPTIONS FOR THE CONTROL OF SILVERLEAF NIGHTSHADE (Solanum elaeagnifolium) Planta Daninha
GITSOPOULOS,T.K.; DAMALAS,C.A.; GEORGOULAS,I..
ABSTRACT Silverleaf nightshade is a difficult-to-control perennial weed. Field experiments were conducted in northern Greece to evaluate the control of silverleaf nightshade with POST applications of glufosinate (1,500 g a.i. ha-1), glyphosate (3,600 g a.i. ha-1), tembotrione (148.5 g a.i. ha-1), and a mixture of tembotrione plus bentazon (148.5 plus 1,440 g a.i. ha-1) at an early vegetative stage (plant height 10-15 cm) and at the beginning of flowering (plant height 30-50 cm). Glufosinate provided > 95% control of silverleaf nightshade from 7 to 39 days after treatment (DAT), regardless of the vegetative stage at herbicide application. Similarly, glyphosate provided up to 90% control around 39 DAT at either growth stage applied, exhibiting gradually...

Chemical Control of Glyphosate-Resistant Goosegrass Planta Daninha
TAKANO,H.K.; OLIVEIRA JR.,R.S.; CONSTANTIN,J.; SILVA,V.F.V.; MENDES,R.R..
ABSTRACT: The use of mixtures and rotation of herbicide modes of action are essential for herbicide resistance management. The purpose of this research was to evaluate different pre- and post-emergence herbicides to control goosegrass in soybean and corn. Four greenhouse experiments were conducted, one in pre-emergence and the three others in post-emergence. In pre-emergence, the number of emerged plants and the control percentage at 20, 35 and 50 days after application were evaluated. In post-emergence, the control percentage was evaluated at 14 and 28 days after application on plants with one tiller and four tillers. The use of residual herbicides to control glyphosate-resistant goosegrass is a very important tool for its effective management. The...
