2. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

3. 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

4. Lymphatic fluctuation in the parenchymal remodeling stage of acute interstitial pneumonia, organizing pneumonia, nonspecific interstitial pneumonia and idiopathic pulmonary fibrosis
Because the superficial lymphatics in the lungs are distributed in the subpleural, interlobular and peribroncovascular interstitium, lymphatic impairment may occur in the lungs of patients with idiopathic interstitial pneumonias (IIPs) and increase their severity. We investigated the distribution of lymphatics in different remodeling stages of IIPs by immuno

5. Asian Rust control and performance of two soybean cultivars submitted to different fungicides and application time / Controle de ferrugem asiática e desempenho de duas cultivares de soja submetidas a diferentes fungicidas e épocas de aplicações
Phakopsora pachyrhizi Syd. &Syd. is the worst threat for soybean crop in the main producers regions around the world, where significant loses has been observed. Many variables in the quantification of damage of this disease have to be studied, such as area under the disease progress curve (AUDPC), healthy leaf area absorption (HAA), healthy leaf area duratio

6. Análise de sobrevivência do tomateiro a Phytophthora infestans / Analysis of the survival of the tomato plant Phytophthora infestans
Reburning caused by Phytophthora infestansis is characterized as an aggressive disease of great destructive impact, capable of limiting or even hindering the economic cultivation of the tomato plant under conditions of high humidity and low temperatures. In view of the problems reburning can cause to tomato plant crops, this work aimed to: 1) fit models to d

7. âEpidemiologia do mofo-cinzento (Amphobotrys ricini Buchw.) da mamoneira" / "Epidemiology of gray mold of castor bean"
The gray mold of castor bean, caused by Amphobotrys ricini, promotes rapid and complete destruction of castor bean bunches under high relative humidity and temperatures around 25 ÂC. Currently, it is the most important disease of the crop in some regions of Brazil. Thus, the objectives of this work were: to characterize cultures of A. ricini from different

8. Diseases under organic cultivation of coffee (Coffea arabica L.): epidemiology and alternative control / âDoenÃas em cultivo orgÃnico do cafeeiro (Coffea arabica L.) : epidemiologia e controle alternativoâ
In the years of 2005 and 2006 two trials were installed in eight year old coffee plantations of the cv. Acaià MG-474-19, under organic and conventional crop systems, in Santo AntÃnio do Amparo, Minas Gerais. The progress of rust and brown eye spot diseases of coffee was assessed as a function of the effect of different biofertilizers, between December/2004

9. Epidemiology and management of coffee (Coffea arabica L.) diseases under organic farming. / Epidemiologia e manejo de doenÃas do cafeeiro (Coffea arabica L.) sob cultivo orgÃnico
The present work aimed to study coffee diseases on organic crop system. For that, rust and black eye spot disease progress on organic and conventional crop systems were compared. The effect of nutrient sources in the disease management was evaluated and, finally, the effect of plant extracts in the protection of coffees in the organic system was tested. The

10. Temporal and spatial dynamics of citrus black spot (Guignardia citricarpa) and quantification of the damages caused to citrus culture. / Dinâmica temporal e espacial da mancha preta (Guignardia citricarpa) e quantificação dos danos causados à cultura dos citros.
The fungus Guignardia citricarpa is the causal agent of citrus black spot (CBS), which is a disease that become the fruits unsightly and unsuitable for the fresh fruit market. Besides, premature fruit drop may occur, reducing the productivity. A diagrammatic scale for the two symptoms of CBS (hard spot and false melanose) was developed to evaluate the severi
