“…Similar results were found in the Meloidogyne incognita race 3 x Fusarium solani interaction on passionfruit of the Maguari cultivar, which is resistant to the nematode (FISCHER et al, 2010). Intensification of F. oxysporum severity, observed by Silva and Pereira (2008) in simultaneous inoculation with M. incognita in ochro, with significant increase of dead plants, also was found in the simultaneous interaction of M. javanica and Foc in the Grande Naine and BRS Princesa cultivars. Result equally reported by Simão et al (2010), when they evaluated the F. oxyporum x M. javanica complex in cultivars and lines of common bean.…”

The interaction Fusarium oxysporum f. sp. cubense (Foc) x nematode and the genetic variability of Foc are the main problems with potential to affect the use of resistant varieties in the management of the Panama disease. The objective of this work was to evaluate the interaction between Foc and Meloidogyne javanica on the banana of the Prata Anã, Grande Naine and BRS Princesa cultivars. The experiment was conducted in a randomized block design, with six treatments and ten replications, which differed in the inoculation time of each pathogen. Simultaneous inoculation with Foc and M. javanica, inoculation with Foc one week before inoculation with M. javanica, and inoculation with M. javanica one week before inoculation with Foc. In addition to the controls, Foc isolated, M. javanica isolated, and cultivars without the pathogens. The seedlings were transplanted in 3-liter pots with sterile soil infested with 40 grams of Foc inoculum at the concentration of 1x10 6 CFU/gram and 1000 eggs and J2 of M. javanica. At the end of 56 days, the treatments with 'Grande Naine' presented the highest reproduction factors of M. javanica. In the 'Prata Anã' no interaction was observed between Foc x M. javanica. The treatments with simultaneous inoculation of the two pathogens, and with Foc a week before, in the 'BRS Princesa', presented the highest external disease indices (DI), which promoted the highest AUDPC. The highest internal DI were observed in the treatments Foc+Mj+Grande Naine, Foc+Mj+BRS Princesa, Mj+Grande Naine+Foc and Foc+BRS Princesa+Mj. The simultaneous presence of M. javanica and Foc increases the severity of the Panama disease in Grande Naine and BRS Princesa cultivars. Keywords: Musa spp.. Fusarium wilt. Root-knot nematodes.

“…The use of cow manure and poultry compost provided better results than sugarcane filter cake; this agrees with previous reports on other plant-parasitic nematodes, which indicate that the nature of the organic matter determines its nematicidal efficiency, along with biota and chemical properties of the soil (Akhtar and Alam, 1993;Akhtar and Malik, 2000;Ferraz et al, 2010). Several organic soil amendments have been used with success to manage plant-parasitic nematodes, such as neem (Azadirachta indica A. Juss) cake (Silva and Pereira, 2008), chitin-rich products (Galper et al, 1990), meat and bone meal (MBM) and several kinds of waste products (Akhtar and Alam, 1993). However, the recommendation for use of any of these amendments depends on the pathosystem: whether it is an annual or perennial crop, the nematode genus and/or species involved, and whether the nematode is associated (or not) with another soil pathogen.…”

Guava decline is a complex disease involving Meloidogyne enterolobii and Fusarium solani and it has caused major direct losses to Brazilian growers. Although several strategies have been sought to control the nematode, the use of organic soil amendments is currently the best approach to manage this disease. To assess the best amount of meat and bone meal (MBM) to be incorporated into the soil, guava seedlings inoculated with M. enterolobii were treated with 1-5% v/v of the MBM. Ninety days later variables related to nematode reproduction and plant development were evaluated, which indicated a potential nematicidal effect of the MBM at 3%. Another experiment assessed nematode-and plant-related variables 90 days after treatment of the seedlings with MBM, chitosan, shrimp shell or neem cake at 3%, 0.05%, 2% and 0.1% v/v, respectively. The MBM ranked first, reducing nematode reproduction. This MBM rate was converted to 25 kg/tree and assessed in three application regimes (monthly, bimonthly or trimonthly), for six months, in an orchard affected by guava decline. The variables assessed were soil density of colony forming units (CFU) of bacteria and fungus, and soil and/or root density of M. enterolobii, Helicotylenchus sp., and of different nematode trophic groups. In all three application regimes the MBM reduced all plantparasitic nematodes in the soil and the fungus CFUs. It also promoted an increase in bacterial CFU and bacterivorous nematodes.Key words: Psidium guajava, Fusarium solani, neem cake, chitosan, shrimp shell, cultural control, guava decline, meat and bone meal. Avaliação em casa de vegetação e em campo de diferentes compostos orgânicos contra Meloidogyne enterolobiiResumo O declínio da goiabeira, uma doença complexa envolvendo Meloidogyne enterolobii e Fusarium solani, tem causado grandes prejuízos diretos para os produtores brasileiros. Apesar de várias estratégias terem sido discutidas para o controle do nematoide, a utilização de matéria orgânica adicionada ao solo é atualmente a melhor abordagem para conviver com essa doença. Para avaliar a dose adequada de farinha de carne e ossos (FCO) a ser incorporada ao solo, mudas de goiabeira inoculadas com M. enterolobii foram tratadas com 1-5% v/v da FCO. Noventa dias após foram avaliadas variáveis relacionadas à reprodução do nematoide e ao desenvolvimento das plantas, indicando um possível efeito nematicida da FCO a 3%. Outro experimento avaliou variáveis relacionadas ao nematoide e à planta 90 dias após o tratamento das mudas com FCO, quitosana, casca de camarão e torta de nem a 3%, 0,05%, 2% e 0,1% v/v, respectivamente. A FCO reduziu a reprodução do nematoide, destacando-se em relação aos demais tratamentos. Esta dosagem de FCO foi convertida para 25 kg planta -1 e avaliada em três regimes de aplicação (mensal, bimestral ou trimestral), por seis meses, em pomar de goiaba acometido pelo declínio. As variáveis avaliadas foram densidade no solo de unidades formadoras de colônia (UFC) de bactérias e fungos, e a densidade no solo e/ou raiz de M. en...

-The effect of plant materials [Sunn Hemp (Crotalaria juncea), Castor Bean (Ricinus communis L.), Cassava (Manihot esculenta Crantz) and Neem (Azadirachta indica)] and the times of incorporation of these materials in regards to the incidence of root rot in melon was evaluated in Ceará state, Brazil. The experiment was conducted in a commercial area with a history of root pathogens in cucurbitaceae. The randomized block design was used, in a 5 x 3 factorial arrangement with four repetitions. The treatments consisted of a combination of four plant materials (sunn hemp, castor beans, cassava and neem) and a control with no soil incorporation of plant material and three times of incorporation (28, 21, and 14 days before the transplanting of the seedlings). Lower incidence of root rot was observed in practically all of the treatments where materials were incorporated at different times, with variation between the materials, corresponding with the time of incorporation, in relation to the soil without plant material. The pathogens isolated from the symptomatic muskmelon plants were Fusarium solani, Macrophomina phaseolina, Monosporascus cannonballus and Rhizoctonia solani, F. solani being encountered most frequently. Resumo -Avaliou-se o efeito de materiais vegetais [Crotalária (Crotalaria juncea), Mamona (Ricinus communis L.), Cassava (Manihot esculenta Crantz) e Nim (Azadirachta indica)] e do tempo de incorporação destes sobre a incidência de podridões radiculares no meloeiro, no estado do Ceará, Brasil. O experimento foi conduzido em área comercial com histórico de patógenos radiculares em cucurbitáceas. O delineamento utilizado foi de blocos casualizados, em esquema fatorial 5 x 3, com quatro repetições. Os tratamentos consistiram da combinação de quatro materiais vegetais (crotalária, mamona, mandioca brava e nim) mais uma testemunha com solo sem incorporação de material vegetal e três tempos de incorporação (28, 21, e 14 dias antes do transplantio das mudas). Menor incidência de plantas com podridão radicular foi observada em praticamente todos os tratamentos onde se incorporou materiais nos diferentes tempos, com variação entre os materiais, conforme o tempo de incorporação, em relação ao solo sem material vegetal. A crotalária proporcionou menor incidência quando a incorporação foi de 14 dias e à medida que aumentou o tempo, houve acréscimo na porcentagem de plantas com podridão. Quando se utilizou a mandioca, houve redução da podridão, proporcionalmente ao tempo de incorporação.
