ABSTRACT - Hairy fleabane (Conyza bonariensis L.) is a major weed of the conventional crop systems.
Therefore, the objectives of the present study were to assess the responses of glyphosate-susceptible (S) and -
resistant (R) C. bonariensis at various developmental stages and evaluate the physiological potential of seeds to
propose alternative herbicides for the control of this weed. Two experiments were performed in replicates. The
first experiment was performed in a greenhouse, arranged in a 2 × 3 × 10 factorial design. Specifically, two
hairy fleabane biotypes (S and R) at different developmental stages (I, II, and III) were subjected to various
treatments (glyphosate, chlorimuron-ethyl, metsulfuron-methyl, diclosulam, ammonium glufosinate, paraquat,
paraquat+diuron, diquat, 2,4-D, and control). Percentage control was evaluated at 7, 14, 21, and 28 days after
the application of the treatments (DAT), and shoot dry mass (SDM) was measured at 28 DAT. The second
experiment was performed in a laboratory to evaluate the physiological potential of seeds based on the weight
of 1000 seeds (TSW); shoot length (SL), radicle length (RL), total length (TL), fresh seedling mass (FSM), dry
seedling mass (DSM), accelerated aging (AA) and cold test (CT), and germination (G) in response to cold and
accelerated aging. The alternative herbicides tested effectively controlled biotype R up to the stage-I. Seeds of
biotype R showed higher physiological potential in terms of all analyzed variables and exhibited greater
tolerance to adverse conditions during seedling establishment. Therefore, strategies for the management of
glyphosate-resistant hairy fleabane should aim at preventing new seed production.
RESUMO - A buva (Conyza bonariensis L.) é umas das principais plantas daninhas dos sistemas de cultivos
conservacionistas, especialmente por sua evolução à resistência ao herbicida glyphosate. Os objetivos deste
trabalho foram verificar a resposta de Conyza bonariensis suscetível (S) e resistente (R) ao glyphosate em
diferentes estádios a herbicidas alternativos e avaliar o potencial fisiológico de sementes destes biótipos. Dois
estudos foram realizados e repetidos, sendo o primeiro em casa de vegetação em esquema fatorial 2x3x10,
sendo A: biótipos de buva (S e R); B: estádios de desenvolvimento (I (1-2 folhas), II (5-6 folhas) e III (30-35
folhas)) e C: herbicidas (glyphosate, chlorimuron-etílico, metsulfuron-methyl, diclosulam, amônio-glufosinato,
paraquat, paraquat+diuron, diquat, 2,4-D além de testemunha não aplicada).O segundo estudo foi desenvolvido
em laboratório, realizando-se avaliações do potencial fisiológico das sementes, a partir do por peso de mil
sementes (PMS), germinação (G), primeira contagem da germinação (PG), índice de velocidade de germinação
(IVG) e emergência (IVE), comprimento da parte aérea (CPA), raiz (CR) e total (CT), matéria seca da parte
aérea (MSPA), raízes (MSR) e total (MST), testes de frio e envelhecimento acelerado. O biótipo CR foi
eficientemente controlado pelos herbicidas alternativos ao glyphosate, utilizados até o estádio de 6 folhas. As
sementes do biótipo CR apresentaram desempenho fisiológico superior em todas as variáveis analisadas, com
maior tolerância a condições adversas em seu estabelecimento. O manejo de buva resistente a glyphosate
demanda a utilização de estratégias que visem evitar a produção de novas sementes. MenosABSTRACT - Hairy fleabane (Conyza bonariensis L.) is a major weed of the conventional crop systems.
