Resumo: | The search of alternative products for tomato bacterial spot has been promoting by the lack of effectiveness registered by the traditional products available. The objective of this work was to evaluate a range of chemical products by in vitro tests, in experiments seedlings and field experiments. The products studied were: acibenzolar-S-methyl; benzalkonium chloride; phosphite; copper hydroxide, copper oxicloreto; metiram + pyraclostrobin and famoxadone + mancozebe. The in vitro tests were carried out at Embrapa Hortaliça, Brasília-DF, in July of 2007. The bactericide action was evaluated on Xanthomonas perforans and X. gardneri. The trial was in a complete randomized block design with four replications and plot was constituted by a Petri plate impregnated with solidified bacterial suspension. The halo of inhibition formed was evaluated. The experiments with seedlings were carried out with the hybrid Heinz 9553 at the commercial nursery VIVATI in Rio Verde, Goiás, in August to September and November to December of 2008. There were three trials in a complete randomized block design with three replications. The products were sprayed by using CO2 portable sprayer. The inoculation occurred 29 days after sowing, with an isolated of X. gardneri. Disease severity was evaluated on 15 leaflets per plot at 14 and 16 days after inoculation of the first and second experiment, respectively. Data was expressed as percentage of leaf affected by program Quant. It was also suggested a possible interaction between the regulator of growth paclobutrazol and the behavior of certain products in the reduction of the severity of the disease. Two field trials were carried out at the experimental farm of Unilever Bestfoods, in Goiânia-GO, from February to June of 2007 and April to August of 2008. The first was with the hybrid Heinz 9992 in a complete randomized block design, with 15 treatments and three replications, and inoculated with X. perforans. The second was in a split plot completely randobized block design with three replications. Variety (Hypeel 108 and U2006) was ascertained for factor A and the 10 treatments for factor B. Xanthomonas perforans and X. gardneri were inoculated in different moments. In both trials foliage severity, number of fruits with symptoms and yield were evaluated. In the second trial fruits with sun scald was also taken. In the in vitro test, the products to which X. perforans and X. gardneri were sensitive in the recommended dose were the benzalkonium chloride and famoxadone + mancozeb. Methiram + pyraclostrobin had action in the dosage recommended only for X. gardneri. Xanthomonas perforans was sensitive to this product only starting from ten times more. The products of copper base did not have action in the bacteria at the recommended dose, being sensitive only at a hundred time more. For the trials of seedlings it was noticed that metiram + pyraclostrobin, copper oxicloreto, famoxadone + mancozebe, phosphite and copper hydroxide reduced the severity under certain conditions. In the field trials, in generally, acibenzolar-S-methyl and famoxadone + mancozeb lead to the better results. |

Sendo assim, este trabalho teve como objetivo avaliar uma gama de produtos químicos em testes in vitro, experimentos com mudas e em experimentos de campo. Foram estudados: acibenzolar-S-metil; cloretos de benzalcônio; fosfitos; hidróxido de cobre, oxicloreto de cobre; metiram + piraclostrobina e famoxadona + mancozebe. Os testes in vitro foram conduzidos na Embrapa Hortaliças, Brasília-DF, em julho de 2007. A ação bactericida dos produtos foi avaliada sobre Xanthomonas perforans e X. gardneri. O ensaio foi em blocos casualizados com quatro repetições e a parcela foi constituída por uma placa de Petri impregnada com suspensão bacteriana solidificada. Avaliou-se o halo de inibição formado. Os experimentos de mudas foram conduzidos com o híbrido Heinz 9553 no viveiro comercial VIVATI em Rio Verde GO, de agosto a setembro e de novembro a dezembro de 2008. Foram três ensaios inteiramente casualizados com três repetições. Os tratamentos (produtos) foram pulverizados na parte aérea utilizando pulverizador costal de barra. A inoculação foi aos 29 dias após a semeadura, com um isolado de X. gardneri. Avaliou-se a severidade da doença em 15 folíolos por parcela aos 14 e 16 dias após a inoculação do primeiro e segundo experimento, respectivamente. Esta foi expressa em porcentagem de área foliar atacada processada pelo programa Quant. É sugerido uma possível interação entre o regulador de crescimento paclobutrazol e o comportamento de certos produtos na redução da severidade da doença. Dois ensaios de campo foram conduzidos na área experimental da Unilever Bestfoods, em Goiânia-GO, de fevereiro a junho de 2007 e de abril a agosto de 2008. O primeiro foi com o híbrido Heinz 9992 em delineamento experimental blocos casualizados, com 15 tratamentos e três repetições. Inoculou-se X. perforans. Já o segundo ensaio foi fatorial em parcelas subdivididas em blocos ao acaso e três repetições. O fator A foi hídrido (Hypeel 108 e U2006) e o fator B (tratamentos). Inoculou-se X. perforans e X. gardneri em momentos distintos. Em ambos ensaios foram avaliados severidade foliar, número de frutos com sintomas e produtividade. No segundo ensaio tomou-se também número de frutos com escaldadura. No teste in vitro os produtos aos quais X. perforans e X. gardneri foram sensíveis na dose recomendada foram os cloretos de benzalcônio e a famoxadona + mancozebe. Metiram + piraclostrobina tiveram ação na dosagem recomendada somente para X. gardneri. Xanthomonas perforans foi sensível ao produto somente a partir de dez vezes maior a dosagem recomendada. Os produtos à base de cobre não tiveram ação nas bactérias na dosagem recomendada, sendo sensíveis apenas na dose cem vezes maior a dosagem recomendada. Em mudas metiram + piraclostrobina, oxicloreto de cobre, famoxadona + mancozebe, fosfito e hidróxido de cobre reduziram a severidade em mudas no ensaio realizado em agosto. Em campo, notou-se que, de maneira geral acibenzolar-S-metil e famozadona + mancozebe estão entre os melhores resultados.Made available in DSpace on 2014-07-29T14:52:10Z (GMT).
