Última Impact of the timing and duration of weed control on the establishment of a rubber tree plantation Anais da ABC (AABC) GUZZO,CAIO D.; CARVALHO,LEONARDO B. DE; GIANCOTTI,PAULO R.F.; ALVES,PEDRO L.C.A.; GONÇALVES,ELAINE C.P.; MARTINS,JOSÉ V.F.. Rubber tree production is reduced by weeds that compete for environmental resources; therefore, the timing and duration of weed control influences weed interference. The objectives of this study were to evaluate the growth of rubber tree (Hevea brasiliensis) plants, to determine the critical period for weed control, and to evaluate the growth recovery of rubber trees that coexisted with weeds for different periods of time after planting. Two groups of treatments were established under field conditions in the first year of the investigation: one group contained crescent periods of weed infestation, while the other contained crescent periods of weed control, also including a weed-free check and a total weedy check. In the second year of the investigation,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Hevea brasiliensis; Weed interference; Critical period for weed control; Growth recovery.

DE; ALVES,PEDRO L.C.A.; DUKE,STEPHEN O.. Weed management systems in almost all Brazilian coffee plantations allow herbicide spray to drift on crop plants. In order to evaluate if there is any effect of the most commonly used herbicide in coffee production, glyphosate, on coffee plants, a range of glyphosate doses were applied directly on coffee plants at two distinct plant growth stages. Although growth of both young and old plants was reduced at higher glyphosate doses, low doses caused no effects on growth characteristics of young plants and stimulated growth of older plants. Therefore, hormesis with glyphosate is dependent on coffee plant growth stage at the time of herbicide application.
