Resumo
O trabalho teve como objetivo avaliar a atividade de um novo composto inseticida de performance toxicológica favorável (chlorantraniliprole), pertencente ao grupo químico antranilamida, aplicado via “drench” em diferentes doses e em mistura com imidacloprido e tiametoxam, sobre as principais pragas do tomateiro (tripes, mosca-branca, mosca-minadora e traça) em ambiente protegido. O experimento foi conduzido em casa-de-vegetação na Fazenda de Ensino e Pesquisa e Extensão da Faculdade de Engenharia de Ilha Solteira, localizado no município de Ilha Solteira. O delineamento experimental foi blocos casualizados com 10 tratamentos e 4 repetições. Cada parcela constou de uma linha da cultura com 10 plantas, totalizando 6 m2, considerando-se as 8 plantas centrais como área útil. Os tratamentos e doses foram: testemunha não aplicada, chlorantraniliprole nas doses de 20, 40 e 80 g i.a.ha-1, chlorantraniliprole + imidacloprido nas doses de 20 + 210 e 40 + 210 g i.a.ha-1, chlorantraniliprole + tiametoxam nas doses de 20 + 50 e 40 + 50 g i.a.ha-1, imidacloprido na dose de 210 g i.a.ha-1 e tiametoxam na dose de 50 g i.a.ha-1. Foram realizadas 3 aplicações, sendo a primeira no dia do transplantio, a segunda (15 dias após o transplante) e a terceira (30 dias após o transplante). As avaliações foram realizadas aos 5, 10 e 15 dias após a primeira aplicação, aos 5, 10 e 15 dias após a segunda e aos 5, 10, 15, 20 e 25 dias após a terceira aplicação, contando o número de adultos de mosca-branca, Bemisia tabaci, tripes, Frankniella schultzei e folíolos atacados por mosca-minadora, Liriomyza huidobrensise e sintomas de traça, Tuta absoluta, encontrados nos ponteiros de 5 plantas tomadas ao acaso em cada parcela. Ninfas de B. tabaci foram contados em 5 folíolos coletados por parcela. Aos 15 dias após a segunda aplicação...
The objective of this work was to study a new insecticide (chlorantraniliprole), from the diamide nitrilics chemical group, applied in diferents doses, and associated with the neonicotinoide thiamethoxam and imidacloprid applied in the soil (drench), on the control the mains tomate pests. The experimente were conducted in the greenhouse at Farm of UNESP University in Ilha Solteira City. The experimental design was randomized blocks with four replications and ten treataments. Each plot consisted of row one of the crop with tem plants, totality 6m2. The treataments and doses were: untreated, chlorantraniliprole at the doses of 20, 40 and 80 g a.i.ha-1, chlorantraniliprole + imidacloprid at the doses of 20 + 210 and 40 + 210 g a.i.ha-1, chlorantraniliprole + thiamethoxam at the doses of 20 + 50 and 40 + 50 g a.i.ha-1, imidacloprid at the dose of 210 g a.i.ha-1 and thiamethoxam at the dose of 50 g a.i.ha-1. It was accomplished three applications: the first application in the day of seeding transplant, the second (15 days after the transplant) the last application (30 days after transplant). The evaluations were accomplished at 5, 10 and 15 days after the first application, 5, 10 and 15 days after the second application and 5, 10, 15, 20 and 25 days after the last application, counting the Bemisia tabaci adults number, Frankniella schultzei and leaflets with Liriomyza huidobrensise and Tuta absoluta (number of mines encountered in the five leaflets in each plot). For nymphs of B. tabaci were collecteds 5 leaflets per plot, that were transportated at Laboratory for couting under microscope. The 15 days after the second application, was counted the number of plants with symptoms of viral disease, in the 8 plants of central plots. The data obtained were submitted to analysis of variance of F Test, and averages were compared by... (Complete abstract click electronic access below)
