ABSTRACT: The challenge of managing herbicide-resistant weeds is an agricultural reality in Brazil that shall not be neglected. In this sense, Ministério da Agricultura, Pecuária e Abastecimento (MAPA) published Act No. 45 on July 14, 2017, provides the inclusion of a code system on labels and leaflets of insecticides, fungicides and herbicides, in order to demonstrate the mode of action of the active ingredient present in the product. In case of mix formulations, both molecules must be discriminated, adopting the same “Herbicide Resistance Action Committee - HRAC” international reference code. The Act No. 45 facilitates the process to choose and adopt products by all those involved in the chain production. It also collaborates with the possible to...

ABSTRACT: The emergence of resistant biotypes of the Amaranthus palmeri species in cotton production areas of the state of Mato Grosso, Brazil, generated the need for correct identification of this species and information on viable herbicidal tools for their management. Thus, greenhouse experiments were conducted to evaluate the efficacy of alternative herbicides applied to A. palmeri in pre and post emergence. A randomized block design with four replications was used. The efficacy of herbicides applied in pre emergence was evaluate in two experiments, one in a clayey and other in a sandy soil; 9 herbicide treatments (8 with herbicide application and a control without application) were applied on each soil. Subsequently, two experiments with different...

MULTIPLE RESISTANCE OF Amaranthus palmeri TO ALS AND EPSPS INHIBITING HERBICIDES IN THE STATE OF MATO GROSSO, BRAZIL

ABSTRACT This work was carried out in order to evaluate the susceptibility to ALS-inhibiting herbicides of the Brazilian biotype of glyphosate-resistant A. palmeri, considering different chemical groups. For that, four experiments were performed, each with one of the following herbicides: glyphosate, chlorimuron-ethyl, cloransulan-methyl and imazethapyr. In each trial, treatments were organized according to a 2x8 factorial scheme, in which two were the species of Amaranthus (A. palmeri and A. spinosus) and eight were the herbicide rates (16D, 8D, 4D, 2D, D, 1/2D, 1/4D and herbicide absence; being D the commercial rate of each product). For glyphosate, D = 720 g a.e. ha-1; for chlorimuron-ethyl, D = 20 g ha-1; for cloransulanmethyl, D = 30 g ha-1; for...
