1. Chlorophyll a fluorescence and leaf temperature are early indicators of oil palm diseases
ABSTRACT Bud rot (BR) caused by Phytophthora palmivora and lethal wilt (LW) whose causal agent is unknown, are two diseases currently posing a threat to the oil palm ( Elaeis guineensis . Jacq) industry. BR, first reported in 1964, has destroyed more than 85,000 ha. LW, first reported in 1994 in the Llanos Orientales in Colombia, has destroyed more than 5,00

3. Methodologies for selecting cassava with resistance to dry and black root rot under controlled conditions
ABSTRACT Cassava root rot diseases such as dry and black root rot are listed among the major threats, since its affect the main product (tuberous roots), causing a progressive decline in yield and affecting subsequent crop cycles, being the use of resistant varieties the most reliable control measure on field level. The objective of this study was to identif

4. Isolation of
Dickeya dadantii strains from potato disease and biocontrol by their bacteriophagesOne of the most economically important bacterial pathogens of plants and plant products is
Dickeya dadantii . This bacterium causes soft rot disease in tubers and other parts of the potato and other plants of theSolanaceae family. The application of restricted host range bacteriophages as biocontrol agents has recently gaBraz. J. Microbiol.. Publicado em: 21/07/2015

5. Temporal analysis of charcoal root rot in forest nurseries under different pathogen inoculum densities and soil moisture content
The progress of charcoal root rot (CRR) disease in Pinus radiata seedlings caused by Macrophomina phaseolina was evaluated in greenhouse and field trials. In one greenhouse trial P. radiata was sown in a sandy soil with pathogen inoculum densities (ID) ranging from 25 to 1000 cfu.g-1. After two months, the seedlings were established under three soil moisture

6. Desempenho horticultural de clones de lima ácida `Tahiti´ enxertados em citrumelo `Swingle´ cultivados com e sem irrigação / Horticultural performance of Tahiti lime selections grafted on Swingle citrumelo under irrigated and non-irrigated conditions
A partir da década de 1990, em função da valorização da fruta no mercado interno e do aumento das exportações da fruta in natura, observou-se aumento da importância da lima ácida Tahiti (Citrus latifolia (Yu. Tanaka) Tanaka) sob os aspectos econômico e social no agronegócio brasileiro. A diversidade genética da espécie é pequena e os cultivos c

7. OcorrÃncia de doenÃas na cultura do crambe (Crambe Hochst abyssinica) cultivado na regiÃo oeste do Paranà e efeito de Xanthomonas campestris pv. campestris na produÃÃo da cultura / Occurrence of diseases in the culture of crambe (Crambe abyssinica Hochst) grown in western Paranà and effect of Xanthomonas campestris pv. campestris in the production of culture
Several factors indicate that petroleun must be replaced by alternative energy sources. In Brazil there are several government programs that encourage research and commercialization of renewable energy. In this context, is strengthening the productive chain of biodiesel, for which various raw materials have been tested with the aim of supplying the market in

8. Herança da resistência da soja à podridão radicular de fitóftora, em variedades comerciais brasileiras
The phytophthora root rot (PRR), caused by Phytophthora sojae (Kaufman &Gerdman), is one of the most destructive soybean diseases and can provoke yield losses of up to 100%. PRR has occurred more frequently in Brazil since the season 2005/06, mainly in the South region. There are some resistant commercial varieties but their inheritance remains unknown. All

9. Sobrevivência de Colletotrichum acutatum, agente causal da podridão floral dos citros, em plantas daninhas / Survival of Colletotrichum acutatum, the causal agent of postbloom fruit drop, on weeds
O Brasil é o maior produtor de laranja do mundo e, embora o cultivo ocorra em todos os estados brasileiros, o Estado de São Paulo é o maior produtor, responsável por 80% da produção nacional. Dentre as doenças que podem limitar a produção dos citros encontra-se a podridão floral do citros (PFC), causada pelo fungo Colletotrichum acutatum J. H. Simm

10. Evidence that the Ceratobasidium-like white-thread blight and black rot fungal pathogens from persimmon and tea crops in the Brazilian Atlantic Forest agroecosystem are two distinct phylospecies
The white-thread blight and black rot (WTBR) caused by basidiomycetous fungi of the genus Ceratobasidium is emerging as an important plant disease in Brazil, particularly for crop species in the Ericales such as persimmon (Diospyros kaki) and tea (Camellia sinensis). However, the species identity of the fungal pathogen associated with either of these hosts i

11. Production of lytic enzymes by Trichoderma isolates during in vitro antagonism with Aspergillus niger, the causal agent of collar rot of peanut
Twelve isolates of Trichoderma (six of T. harzianum, five of T. viride, one of T. virens), which reduced variably the incidence of collar rot disease caused in peanut by Aspergillus niger Van Tieghem, were evaluated for their potential to produce lytic enzymes during in vitro antagonism. T. viride 60 inhibited highest (86.2%) growth of test fungus followed b

12. Phenology of the oil palm interspecific hybrid Elaeis oleifera × Elaeis guineensis
Oil palm is one of the most important oil crops in the world. Because of its high productivity and perennial nature, it has been expanding quickly. Commercial plantations consist mostly of the African palm E. guineensis Jacq. However, producers in Latin America are increasingly planting the O × G interspecific hybrid, a cross between African palm (E. guinee
