Fitossociologia de plantas daninhas em cultivos de feijão sobre diferentes manejos de herbicidas

Abstract: O conhecimento das alterações na comunidade infestante provocado pelo manejo de plantas daninhas é importante para definição de estratégias eficientes para o controle destas. Realizou-se um experimento de campo para avaliar os efeitos do uso de herbicidas em diferentes alturas de barra na dinâmica de plantas daninhas e produtividade do feijoeiro. Adotou-se arranjo fatorial em esquema 3x4+1, constituído pela combinação de três herbicidas (fomesafen, fluazifop-p-butil e sua mistura) e quatro alturas de barras do… Show more

“…40, dated October 11, 2018(MAPA, 2019, the use of herbicides in tank mixing will be an increasingly used practice by producers, but lacking studies that prove the effectiveness of these mixtures over weed control, possible damage to crops of interest Pucci, L. F. et al 361 signalgrass (Urochloa decumbens), "falsa serralha" (Emilia fosbergii) and "estrelinha" (Melampodium perfoliatum), plants commonly found in coffee plantations and of greater abundance in the area. This evaluation was performed using a square of 0.5 x 0.5 m (0.25 m 2 ) that was randomly launched twice in a representative area of each plot and the target weeds were then identified and evaluated the percentage of control (Barcellos Júnior et al, 2016). At 30, 68 and 104 DAA were also evaluated the intoxication caused in plants, according to the grading scale proposed by the Brazilian Society of Weed Science (SBCPD, 1995), where 0% represents no injury to plants and 100%, total death.…”
