The control of melon wilt caused Fusarium oxysporum f. sp. melonis (Fom) has become a complex problem for (Cucumis melo L.) growers worldwide. In this study, we evaluated the ability Trichoderma spp. to under field conditions, and application liquid compost as food-based strategy improve biocontrol efficiency selected strain. first experiment, use harzianum LCB47, viride LCB48, koningii LCB49, polysporum LCB50 in naturally infested soil. treatment with T. (Tp) showed highest (44.85%),...

Abstract Land‐use change (LUC) can impact soil quality. In semi‐arid areas of Brazil, impacts LUC need to be understood for better management. This study evaluated the on organic carbon (SOC), nitrogen (N), and phosphorus (P) distributions through profile stocks a Haplic‐Cambisol in Brazilian Semi‐arid region. Three land‐use systems (LUS) were investigated: agricultural management (30 years), regeneration under controlled grazing (25 years) after 5 years arable management, native dry forest....

A palma forrageira, recebendo aporte adicional de água, pode se constituir em alternativa alimentar para os rebanhos da região semiárida brasileira, entretanto são escassas as informações sobre respostas produtivas e estruturais dos genótipos, assim como do intervalo cortes planta. Esta pesquisa teve o objetivo avaliar características genótipos forrageira diferentes intervalos corte. O delineamento experimental foi blocos completos casualizados com parcelas subdivididas tendo dispostos nas...

Plant species that naturally occur in the Brazilian Caatinga(xeric shrubland) adapt several ways to these harsh conditions, and can be exploited increase crop production. Among strategic adaptations confront low water availability, desiccation tolerance stands out. Up now, association of those with beneficial soil microorganisms is not well understood. The aim this study was characterize Tripogon spicatusdiazotrophic bacterial isolates from Caatingabiome evaluate their ability promote plant...

Soil organic matter (SOM) plays a key role in maintaining the productivity of tropical soils, providing energy and substrate for biological activity modifying physical chemical characteristics that ensure maintenance soil quality sustainability ecosystems. This study assessed medium-term effect (six years) application five composts, produced by combining different agro-industrial residues, on accumulation matter. Treatments were applied long-term experiment management mango (OMM) initiated...

We studied the dispersal behavior and survival of sterile medfly males either treated or not with ginger root oil (GRO), in field conditions, Petrolina-PE, northeast Brazil, from May 2006 to December 2007 a insect technique (SIT) program. The tsl strain Vienna 8 Ceratitis capitata Wied. (Diptera: Tephritidae), medfly, mass-rearing facility located Juazeiro-BA, was used. results showed that exposed GRO exhibit similar postrelease survival. More than 60% males, treared wth GRO, were recovered...

Abstract The sterile insect technique (SIT) is widely used as part of an integrated approach to reduce field populations the Mediterranean fruit fly ( Ceratitis capitata , Diptera: Tephritidae). Aromatherapy based on exposure ginger root oil (GRO) volatiles known a method significantly improve sexual performance medfly males, and being in many mass‐rearing facilities around world. However, optimum dose GRO not well defined. This work evaluated laboratory cages four different doses control...

Patógenos oriundos do solo têm se tornado uma forte limitação ao cultivo meloeiro nas condições edafoclimáticas predominantes no Vale Submédio São Francisco. Uma vez que o controle deste grupo de patógenos utilizando fungicidas tem mostrado pouco eficiente, faz necessário desenvolvimento alternativas possam ser aplicadas manejo integrado das doenças causadas por estes patógenos. Com este objetivo, quatro isolados Trichodema spp. foram avaliados quanto a habilidade para colonização da...

Abstract This study aimed to select surfactant compounds improve the dispersion of emulsifiable conidial suspensions Beauveria bassiana for field application while maintaining high conidia viability. Surfactant compatibility was initially evaluated by colony growth in culture media amended with increasing doses surfactants. In a second experiment, germination rate after temporary exposure under laboratory conditions. The effect hydrophilic–lipophilic balance (HLB) surfactants on and...
