Alternativas para o controle de soja RR® voluntária na cultura do algodoeiro
Pereira Braz, Guilherme Braga; Oliveira Jr., Rubem Silvério; Constantin, Jamil; Oliveira Neto, Antonio Mendes; Dan, Hugo Almeida; Guerra, NaiaraCom o advento do cultivo de algodão em segunda safra, o controle de plantas voluntárias de soja RR® tornou-se uma operação indispensável na cotonicultura. Assim, o presente trabalho teve por objetivo avaliar a eficiência de diferentes alternativas de controle químico de plantas voluntárias de soja RR®, mediante a avaliação de herbicidas empregados no algodão. Foram instalados dois experimentos em casa de vegeta...
Seletividade de aplicações combinadas de herbicidas em pré e pós-emergência par...
Osipe, Jethro Barros; Oliveira Jr., Rubem Silvério de; Constantin, Jamil; Biffe, Denis Fernando; Rios, Fabiano AparecidoDentro de sistemas de manejo de plantas daninhas, a aplicação de herbicidas em pré-emergência é uma opção interessante, visto que eles são uma importante ferramenta no manejo de populações resistentes. Objetivou-se com este trabalho avaliar a seletividade de herbicidas aplicados em pré-emergência na cultura da soja, combinados ou não à aplicação de glyphosate em pós-emergência, em solo de textura argilosa. O de...
selectivity of preemergence herbicide treatments for cotton crop
Barroso, Alberto Leão de Lemos; Dan, Hugo Almeida; Oliveira Junior, Rubem Silvério de; Constantin, Jamil; Dan, Lilian Gomes de MoraesThe use of preemergence herbicides in cotton crop is one of the main tools in weed control. However, little is known about the effects of different herbicide tank mixtures on this crop. Therefore, this work was aimed at evaluating the selectivity of herbicides applied isolated or in mixtures to cotton at preemergence. Herbicide treatments included alachlor, s-metolachlor, diuron, prometryn, trifluralin, oxyfluo...
The leaching of trifloxysulfuron-sodium and pyrithiobac-sodium in soil columns ...
Guerra, Naiara; Oliveira Júnior, Rubem Silvério de; Constantin, Jamil; Oliveira Neto, Antonio Mendes de; Dan, Hugo de AlmeidaScarce research has been published concerning the effect of soil pH on the leaching potential of herbicides in tropical soils. Thus, we designed this study to evaluate the influence of soil liming on the leaching of trifloxysulfuron-sodium and pyrithiobac-sodium after simulated rainfall depths in soil columns. In the study, two trials were conducted simultaneously; the first experiment evaluated trifloxysulfuro...
Qualidade fisiológica das sementes de soja rr em resposta ao uso de diferentes ...
Albrecht, Leandro Paiola; Alonso, Diego Gonçalves; Constantin, Jamil; Oliveira Jr., Rubem Silvério de; Braccini, Alessandro de Lucca eO objetivo do presente trabalho foi avaliar a qualidade fisiológica das sementes da soja RR, sob efeito do manejo com glyphosate em pós-emergência, aplicado em misturas ou isolado, de forma sequencial. O trabalho foi constituído de três experimentos com distintos tratamentos, instalados no ano agrícola 2006/2007, no município de Floraí. O delineamento experimental utilizado foi o de blocos ao acaso, com doze tr...
Contrasts among origins of corn hybrids in relation to their susceptibility to ...
Cavalieri, Sidnei Douglas; Oliveira Junior, Rubem Silvério de; Constantin, Jamil; Biffe, Denis Fernando; Alonso, Diego GonçalvesHerbicide selectivity is the basis for successfull weed chemical control in agricultural production, as it is considered as a measurement of the difeerential response of different plant species to a certain herbicide. The objective of this work was to evaluate the effect of the origin of corn hybrid in relation to its susceptibility to the herbicides nicosulfuron and isoxaflutole. The research was conducted in ...
Control of different species of Sida spp. with sequential applications of flumi...
Constantin, Jamil; Junior, Rubem Silvério de Oliveira; Kajihara, Luciano Hiroyuki; Arantes, João Guilherme Zanetti de; Cavalieri, Sidnei DouglasDifferent species of genus Sida are important common weeds. They are considered extensively disseminated species and are hard to control. This trial aimed to evaluate the efficacy of sequential applications of sublethal rates of flumicloracpentil to control four species of Sida sp. of frequent occurrence in the north and northewest Paraná state, in comparison with a single application of the herbicide, both at ...
Alterations in physical and chemical properties of a distrofic red latosol unde...
Trintinalio, Juliano; Tormena, Cássio Antonio; Oliveira Júnior, Rubem Silvério de; Machado, Jorge Luiz; Constantin, JamilStudies aiming to evaluate soil management systems in inter-rows of peach palm are still scarce in Brazil. This work was proposed to evaluate the effects of different soil management systems in peach palm inter rows on chemical and physical properties of a dystrophic Red Latosol. Treatments evaluated included weed control with herbicides (HB); soil covered with sugarcane bagasse (SB); alternate green manures wi...
