Resumo: Effect of silicon and acibenzolar-s-methyl on colored cotton plants infested or not with Aphis gossypii Glover (Hemiptera, Aphididae). The aphid Aphis gossypii is an insect pest that causes damage mainly at the beginning of the cotton plant development. The effect of resistance inductors silicon and acibenzolar-s-methyl (ASM) on the development of colored cotton plants were researched in the presence and absence of A. gossypii. Three colored cotton cultivars were sown in pots and individually infested with 25 apterous aphids, 13 days after the application of the inductors. Fifteen days after plant emergence, the silicon was applied at a dosage equivalent to 3 t/ha and acibenzolar-s-methyl in 0.2% solution of the product BION 500®. After 21 days of infestation the following parameters were evaluated: plant height, stem diameter, dry matter of aerial part and root, and total number of aphids replaced. It was verified that the plant height was reduced in the presence of aphids and all variables were negatively affected by the application of ASM. However, silicon did not affect plant development.

O pulgão Aphis gossypii é um inseto-praga que causa danos principalmente no início do ciclo do algodoeiro. Foram pesquisados os efeitos dos indutores silício e acibenzolar-s-methyl (ASM) no desenvolvimento de plantas de algodão colorido, na presença e ausência de A. gossypii. Três cultivares de algodão colorido foram semeadas em vasos e individualmente infestadas com 25 pulgões ápteros, 13 dias após a aplicação dos indutores. Quinze dias após emergência das plantas o silício foi aplicado na dosagem equivalente a 3 t/ha e o acibenzolar-s-methyl (ASM) na solução 0,2% do produto BION 500®. Após 21 dias da infestação foram avaliados os seguintes parâmetros: altura da planta, diâmetro do caule, massa seca da parte aérea e da raiz, e o número total de pulgões repostos. Verificou-se que apenas a altura das plantas foi reduzida pela presença do pulgão e que todas as variáveis estudadas foram afetadas negativamente pela aplicação do ASM, porém não se observou efeito negativo do silício no desenvolvimento das plantas.Sociedade Brasileira de Entomologia2019-11-14T17:03:43Z2019-11-14T17:03:43Z2011-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfALCANTARA, E.; MORAES, J.
