Resumo: | This study had as objectives evaluate the efficacy and selectivity of herbicides for the cultivation of papaya. Two experiments were conducted in field conditions in WG FRUTICULTURA, Sitio Sumidouro, Barauna - RN. In the first the herbicides were applied in pre-emergence of the weeds, before transplanting the papaya seedlings, being evaluated the following treatments: ametryn, diuron, ametryn+diuron, flumioxazin, isoxaflutole, two more witnesses, with and without weeding. At 7, 14, 21 and 28 days after the application of herbicides were realized visual evaluations of intoxication in papaya plants. At 0, 30, 45, 60 and 75 days after the application, evaluations were carried out for plant height and stem diameter. And at 21.42 and 63 days after the application evaluations were carried out on the mass of dry matter of weeds. The ametryn herbicides, diuron, flumioxazin, and the mix of diuron+ametryn, caused severe toxicity in papaya plants, causing them to die. The isoxaflutole caused intoxication in papaya seedlings that showed recovery at the end of the trial period. The weed interference resulted in papaya plants with smaller diameter of the stem, although the height of plants was not influenced. In the second experiment were evaluated eight herbicides (glyphosate, glufosinate-ammonium, paraquat, metribuzin, flumioxazin, ametryn, fluazifop-p-butil+fomesafen and atrazine), with two modes of application (with and without protection of the stem of the papaya plant). The application of herbicide was performed when plants had 0.70 m tall and for the treatments with protection of the stemwas used a polyethylene plate, placed beside the plant. At 7, 14, 21 and 35 days after application of herbicides were realized visual evaluations of weed control by species. At 45 days after application was performed evaluation of dry matter of weeds. For the papaya crop, were realized visuals evaluations of intoxication at 7, 14, 21 and 35 days after application at 0, 21, 42 and 63 days after application were realized evaluations for plant height and stem diameter. The main species of weeds in the area were Commelina benghalensis and Digitaria sanguinalis. The herbicide atrazine has caused intoxication in papaya plants independent of stem protection. The application of the paraquat, ametryn, metribuzin, glyphosate and fluazifop-p-butil+fomesafen require the protection of the stalk of the papaya plant. The glyphosate was effective on the control of the weeds, except for C. benghalensis. The herbicide glufosinate-ammonium, paraquat, metribuzin, flumioxazin, ametryn and the mix fluazifop-p-butylated+fomesafen showed potential for use in papaya plant |

Dois experimentos foram conduzidos em condições de campo na WG FRUTICULTURA, Sítio Sumidouro, Baraúna RN. No primeiro os herbicidas foram aplicados em pré-emergência das plantas daninhas, antes do transplante das mudas de mamão, sendo avaliados os seguintes tratamentos: ametryn, diuron, ametryn+diuron, flumioxazin, isoxaflutole, mais duas testemunhas, com e sem capinas. Aos 7, 14, 21 e 28 dias após aplicação dos herbicidas foram realizadas avaliações visuais de intoxicação nas plantas de mamão. Aos 0, 30, 45, 60 e 75 dias após aplicação, foram realizadas avaliações de altura de plantas e diâmetro do caule. E aos 21,42 e 63 dias após aplicação foram realizadas avaliações da massa da matéria seca das plantas daninhas. Os herbicidas ametryn, diuron, flumioxazin e a mistura ametryn+diuron causaram severa intoxicação nas plantas de mamão, causando-lhes a morte. O isoxaflutole causou intoxicação nas mudas de mamão que apresentaram recuperação no final do período experimental. A interferência das plantas daninhas resultou em plantas de mamão com menor diâmetro do caule, embora a altura de plantas não tenha sido influenciada. No segundo experimento foram avaliados oito herbicidas (glyphosate, amônio-glufosinato, paraquat, metribuzin, flumioxazin, ametryn, fluazifop-p-butil + fomesafen e atrazine), com dois modos de aplicação (com e sem proteção do caule das plantas de mamão). A aplicação dos herbicidas foi realizada quando as plantas estavam com 0,70 m de altura e para os tratamentos com proteção do caule, utilizou-se uma placa de polietileno, colocada ao lado da planta. Aos 7, 14, 21 e 35 dias após aplicação dos herbicidas foram realizadas avaliações visuais de controle de plantas daninhas por espécie. Aos 45 dias após aplicação foi realizada avaliação da massa da matéria seca das plantas daninhas. Para a cultura do mamão, foram realizadas avaliações visuais de intoxicação aos 7, 14, 21 e 35 dias após aplicação, aos 0, 21, 42 e 63 dias após aplicação foram realizadas avaliações de altura de plantas e diâmetro do caule. As principais espécies de plantas daninhas infestantes na área foram Commelina benghalensis e Digitaria sanguinalis. O herbicida atrazine causou intoxicação nas plantas de mamão independente da proteção do caule. A aplicação do paraquat, ametryn, metribuzin, glyphosate e fluazifop-p-butil + fomesafen requerem a proteção do caule do mamoeiro. O glyphosate foi eficaz no controle das plantas infestantes, exceto a C. benghalensis. Os herbicidas amônio-glufosinato, paraquat, metribuzin, flumioxazin, ametryn e a mistura fluazifop-p-butil + fomesafen mostraram potencial para uso no mamoeiroCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal Rural do Semi-ÁridoBRCentro de Ciências Agrárias - CCAUFERSAPrograma de Pós-Graduação em FitotecniaMendonca, VanderCPF:66616620697http://lattes.cnpq.br/4327895435746416Freitas, Francisco Claudio Lopes deCPF:69935319687http://lattes.cnpq.br/0060989785573065Ferreira, Lino RobertoCPF:28300319620http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783318Y2Nascimento, Paula Gracielly Morais Lima do2016-08-12T19:15:19Z2013-12-112011-02-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfNASCIMENTO, Paula Gracielly Morais Lima do.
