Resumo: | During the application of pesticides on soybean fields, a vertical deposition gradient of the product can occur throughout the canopy, resulting in difficulties for controlling stink bugs that are in the middle and lower thirds of plants. This study aimed at evaluating the systemicity of thiamethoxam insecticide in different soybean phenological stages, using brown stink bugs as bioindicators of the pesticide efficacy. The study combined product application sites (lower, middle and upper third) and stink bugs infestation areas at five soybean phenological stages (R2, R3, R4, R5.2 and R6). For the R2 and R5.2 stages, plants presented acropetal translocation of the product, being the effect more evident in the R2 stage. For the R3, R4 and R6 stages, the product translocation was not sufficient for controlling the stink bugs. In all stages, for treatments with direct exposure (same infestation and spraying place), stink bugs were satisfactorily controlled. |

Objetivou-se avaliar a sistematicidade do inseticida tiametoxam em diferentes estágios da cultura da soja, utilizando-se o percevejo marrom como bioindicador da ação do inseticida. O estudo combinou locais de aplicação do produto (terço inferior, médio e superior) e de infestação dos percevejos, em cinco fases do estágio fenológico (R2, R3, R4, R5.2 e R6) da cultura da soja. Nos estágios R2 e R5.2, as plantas apresentaram translocação acropetal do produto, sendo o efeito mais pronunciado no estágio R2. Nos estágios R3, R4 e R6,não houve translocação suficiente do produto para o controle dos percevejos. Em todos os estágios, nos tratamentos com exposição direta (mesmo local de infestação e pulverização), houve controle satisfatório dos percevejos.Escola de Agronomia - Universidade Federal de Goiás2016-04-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/38908Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 1, Jan./Mar. 2016; 96-101Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 1, jan./mar. 2016; 96-101Pesquisa Agropecuária Tropical; v. 46, n. 1, jan./mar. 2016; 96-1011983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/38908/20894Basso, Claudir JoséKuss, Cassiano CarlosPias, Osmar Henrique de CastroMuraro, Dionei SchmidtCutti, Luaninfo:eu-repo/semantics/openAccess2020-07-13T17:50:16Zoai:ojs.revistas.ufg.br:article/38908Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:11.323072Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
