Coffee, one of the most heavily globally traded agricultural commodities, has been categorized as a highly sensitive plant species to progressive climatic change. Here, we summarize recent insights on coffee plant's physiological performance at elevated atmospheric carbon dioxide concentration [CO2]. We specifically (i) provide new data crop yields obtained under free-air CO2 enrichment conditions, (ii) discuss predictions future based rising temperature and (iii) emphasize role [CO2] key...
Tropical and plantation crops include important for food security alternative energy resources. Even so, there are few studies on the impact of climate change diseases these crops. Findings from previous concerning some climate‐change effects coffee, sugarcane, eucalyptus, cassava, citrus, banana, pineapple, cashew, coconut papaya have been summarized to provide a context. By reviewing available methods evaluate tropical crops, we present trends their management strategies, identify critical...
Human activities are altering greenhouse gas concentrations in the atmosphere and causing global climate change. In near future, there will certainly be changes Brazilian phytosanitary scenario attributed to The impacts of change can positive, negative or neutral, since these decrease, increase have no impact on diseases, depending each region period. These also observed plants other organisms as well agroecosystem components. However, not easily determined, consequently, specialists from...
Coffee (Coffea spp.), a globally traded commodity, is slow-growing tropical tree species that displays an improved photosynthetic performance when grown under elevated atmospheric CO2 concentrations ([CO2]). To investigate the mechanisms underlying this response, two commercial coffee cultivars (Catuaí and Obatã) were using first free-air enrichment (FACE) facility in Latin America. Measurements conducted contrasting growth seasons, which characterized by high (February) low (August) sink...
The objective of this work was to assess the potential impact climate change on spatial distribution coffee nematodes (races Meloidogyne incognita) and leaf miner (Leucoptera coffeella), using a Geographic Information System. Assessment impacts pest infestations disease epidemics in crops is needed as basis for revising management practices minimize crop losses climatic conditions shift. Future scenarios focused decades 2020's, 2050's, 2080's (scenarios A2 B2) were obtained from five General...
A long-term assay was conducted to evaluate the environmental impacts of agriculture use sewage sludge on a tropical soil. This paper describes and discusses results obtained by applying interdisciplinary approach valuable insights gained. Experimental site located in Jaguariúna (SP, Brazil). Multiyear comparison developed with application from wastewater treatment plants at Barueri (domestic industrial sewage) Franca sewage), São Paulo State. The treatments were control, mineral...
Risk analysis of climate change on plant diseases has great importance for agriculture since it allows the evaluation management strategies to minimize future damages. This work aimed simulate scenarios coffee rust (Hemileia vastatrix) epidemics by elaborating geographic distribution maps using a model that estimates pathogen incubation period and output from three General Circulation Models (CSIRO-Mk3.0, INM-CM3.0, MIROC3.2.medres). The climatological normal 1961-1990 was compared with...
Among several alternative agricultural systems have been developed, organic agriculture has deserved increasing interest from. The objective of this paper was comparing both (OS) and conventional (CS) tomato cropping for varieties Débora Santa Clara, through an interdisciplinary study. experiment set up in a randomized blocks design with six replicates, dystrophic Ultisol plots measuring 25 ´ 17 m. Cropping procedures followed by either local or growers practices recommendations....
Despite the recent interest in organic agriculture, little research has been carried out this area. Thus, objective of study was to compare, a dystrophic Ultisol, effects and conventional agricultures on soil organism populations, for tomato (Lycopersicum esculentum) corn (Zea mays) crops. In general, it found that fungus, bacterium actinomycet populations counted by number colonies media, were similar two cropping systems. CO2 evolution during season higher, up double agriculture system as...
Abstract: The objective of this work was to evaluate the potential impact climate change on occurrence grapevine downy mildew in Brazil. Seedlings containing four six leaves were sprayed with a sporangia suspension 105 per milliliter. After spraying, seedlings subjected temperatures 26, 28, 29.1, 30.4, and 31.8°C for 24 hours. percentage diseased leaf area latent period evaluated. Maps geographic temporal distribution disease made considering monthly average mean air temperature wetness...
Crop management may modify soil characteristics, and as a consequence, alter incidence of diseases caused by soilborne pathogens. This study evaluated the suppressiveness to R. solani in 59 samples from microbasin. Soil sampling areas included undisturbed forest, pasture fallow ground areas, annual crops, perennial ploughed soil. The were characterized according abiotic variables (pH; electrical conductivity; organic matter content; N total; P; K; Ca; Mg; Al; H; S; Na; Fe; Mn; Cu; Zn; B;...
O conhecimento dos prováveis impactos das mudanças climáticas globais sobre a ocorrência de doenças plantas é grande importância para o setor agrícola, pois permite elaboração estratégias controle. presente trabalho teve por finalidade estudar os possíveis sigatoka-negra da bananeira, meio mapas distribuição doença confeccionados partir cenários disponibilizados pelo IPCC. Os mostraram que haverá redução área favorável à no país. Tal será gradativa as décadas 2020, 2050 e 2080 forma mais...
The predicted atmospheric carbon dioxide concentration's increases are likely to alter plant-pathogen interactions. To assess the effects on rice blast, during three years (2007, 2008 and 2009), cultivars (Agulha Precoce, Shao Tiao Tsao Caloro) were exposed elevated CO2 air concentration (approximately 100 - 300 µmol mol-1 higher than ambient) in open-top chamber facility. disease was more severe under high concentration. Area progress curve 35.43 17.48 for current Leaves of treated plants...
O aumento da concentração de dióxido carbono (CO2) atmosférico, como resultado ação antrópica, pode causar alterações na morfologia e nos processos fisiológicos das plantas, assim no ciclo dos patógenos sua interação com os hospedeiros. presente estudo teve por objetivo avaliar o efeito do CO2 atmosférico sobre a severidade oídio (Microsphaera diffusa) soja crescimento nodulação planta.O experimento foi conduzido em estufas topo aberto (OTC) sem injeção testemunha tratamento estufa,...
A solarização é um método de desinfestação que consiste na cobertura do solo com filme polietileno transparente, durante o período intensa radiação solar, e atua por meio aumento da temperatura solo. Quatro ensaios foram realizados no estado São Paulo, nos municípios Mogi das Cruzes, Jarinu, Piracicaba Itatiba, anos 2000 2001, objetivo avaliar os efeitos nas propriedades físicas, químicas biológicas dos solos. reduziu significativamente a resistência à penetração solos Itatiba.
