Physiological attributes of Enlist E3™ soybean seed submitted to herbicides application Planta Daninha
R. Garcia,Jéssica; M. Vargas,Andrés A.; T. Perboni,Lais; A. Souza,Edna; Tessaro,Daniela; R. Lucio,Felipe; Agostinetto,Dirceu.
Abstract Background: Enlist E3™ soybean is tolerant to 2,4-D, glyphosate and ammonium-glufosinate and were developed for effective management of herbicide resistant weeds such as glyphosate Herbicides, even being selective, can cause damage to crop metabolism, affect growth and development and interfere with seed physiological quality. Objective: The aim of this research was to evaluate the physiological quality of Enlist E3™ soybean seeds submitted to herbicide application. Methods: The field trial was carried out in a randomized block design with four replications. The treatments tested were 2,4-D choline + glyphosate, 2,4-D choline, glyphosate + 2,4-D amine and ammonium-glufosinate; and control without application, sprayed at V6 soybean growth...

Resistance detection of blackjack to ALS inhibitors by in vitro plant growth method Planta Daninha
Tessaro,Daniela; Benneman,Daiane; T. Perboni,Lais; R. Garcia,Jéssica; M. Teixeira,Marlon; Agostinetto,Dirceu.
Abstract Background: The resistance of weeds to herbicides is a problem that has been increasingly studied because of its great importance in agriculture and rapid growth of this phenomenon worldwide. The quick detection of resistant plants is extremely important for resistance management. Weed resistance to herbicides can be detected through field, greenhouse and laboratory tests. A fast way of detecting resistance is using tissue culture method, where is possible to use resistant plant clones and obtain results faster than whole-plant method in greenhouse. Objective: The aims of the research were to detect the resistance of blackjack to herbicides inhibitors of the acetolactate synthase (ALS), addition in vitro cultivation; determine the herbicide...

Herbicidal activity of kidney leaf mud plantain leaves extracts on the germination of four species Planta Daninha
T. Perboni,Laís; Agostinetto,Dirceu; Gazola,Juliano; Tessaro,Daniela; M. Teixeira,Marlon; Neutzling,Alessandro.
Abstract Background: Plants synthesize compounds of specialized metabolism to defend themselves against biotic and abiotic stresses. These compounds could be used as models for pesticide development. Among the species that have not yet been studied for the potential to produce active compounds is the kidney leaf mud plantain (Heteranthera reniformis). Objective: The goal was to evaluate the effect of hexanic, ethyl acetate and methanolic extracts of H. reniformis leaves on cress (Lepidium sativum) seed germination to determine which one have the highest biological activity; and to evaluate different concentrations of extract with the highest biological activity on lettuce (Lactuca sativa), barnyard grass (Echinochloasp.) and giant arrowhead (Sagittaria...
