1. Potato genotypes reaction to early blight and late blight in organic cultivation
RESUMO: O manejo de doenças nos cultivos convencionais de batata requer emprego de maior quantidade de produtos fitossanitários e de maior toxicidade em relação ao cultivo orgânico, que pode acarretar riscos a saúde humana e impacto ambiental. Este trabalho teve como objetivo avaliar o rendimento e a reação de genótipos de batata à requeima e à p

2. Field resistance of potato cultivars to foliar early blight and its relationship with foliage maturity and tuber skin types
Three field experiments were carried out to assess the level of resistance of several cultivars to early blight (EB) and to examine the association between host resistance and either foliage maturity or tuber skin types. A total of 26 cultivars were used in Exps. 1 and 2, and 24 in Exp. 3. Plants were inoculated with isolates of Alternaria grandis at 31 days

3. BRS Notável: a medium-early-maturing, disease-resistant Carioca common bean cultivar with high yield potential
BRS Notável is a common bean cultivar with carioca grain, suitable for cultivation in 20 Brazilian states. It is a medium-early-maturing cultivar, with an average yield of 2,261 kg ha-1, 8.5% higher than the controls, a high yield potential (4,472 kg ha-1), lodging tolerance and resistance to anthracnose, fusarium wilt, common bacterial blight, and curtobac

4. Vegetative and productive aspects of organically grown coffee cultivars under shaded and unshaded systems
Although Coffea arabica species has its origin in the African understories, there is great resistance on the part of the Brazilian producers for growing this species under agroforestry systems as they fear that shading reduces production. This study aimed at evaluating some vegetative traits and the productivity of organically grown coffee (Coffea arabica L.

5. Ação de fungicidas e indutores de resistência no controle da requeima e pinta preta na cultura da batata / Fungicides and resistance inductors action in the control of late and early blight in potato crops
Late blight, caused by the oomycete Phytophthora infestans and early blight, caused by the fungus Alternaria solani, are among the most destructive diseases of potato crops in Brazil and worldwide. Considering the importance of the chemical control on integrated systems and the need for detailed knowledge of the performance of resistance inducers and fungici

6. PREVISÃO DA OCORRÊNCIA DE REQUEIMA E ALTERNARIA EM TOMATEIRO INDUSTRIAL IRRIGADO SOB DUAS CONDIÇÕES CLIMÁTICAS E SEU CUSTO / FORECAST OF LATE BLIGHT AND EARLY BLIGHT ON PROCESSING TOMATO UNDER TWO CLIMATE CONDITIONS AND ITS COST
A cultura do tomate (Lycopersicon esculentum Mill) é uma das mais expressivas culturas no cenário agrícola mundial, constituindo importante produto para o comércio in natura e indústria de extratos. O volume de fungicidas utilizado na cultura do tomateiro no controle das principais doenças é elevado e contribui significativamente nos custos de produç

7. Fungitoxicity against alternaria solani, control of early blight and effect on the growth of tomato (Lycopersicum esculentum Mill) plants by homeopathic drugs / Fungitoxicidade contra alternaria solani, controle da pinta preta e efeito sobre o crescimento do tomateiro (Lycopersicum esculentum Mill) por medicamentos homeopÃticos
O tomate (Lycopersicon esculentum Mill) à a segunda hortaliÃa mais consumida no Brasil. A doenÃa pinta preta, causada pelo fungo Alternaria solani à uma das mais importantes. O tratamento normalmente à feito com fungicidas o que ocasiona a produÃÃo de frutos contaminados por resÃduos de agrotÃxicos. O uso da homeopatia tem sido uma prÃtica relevant

8. Genética molecular de populações de Alternaria solani no Brasil / Molecular population genetics of Alternaria solani in Brazil
The analysis of the genetic structure of the population of Alternaria solani is an important component of the molecular epidemiology potato (Po) and tomato (To) early blight. Isolates were sampled from the Northeast, Central-West, Southeast, and South regions of Brazil. AFLP and RAPD markers were used to estimate genetic diversity. A multilocus combined data

9. DESENVOLVIMENTO DE CLONES DE BATATA DE ALTA QUALIDADE DE TUBÉRCULO A PARTIR DE GENITORES RESISTENTES A REQUEIMA / DEVELOPMENT OF POTATO CLONES WITH HIGHT TUBER QUALITY FROM LATE BLIGHT RESISTENT PROGENITORS
Potato (Solanum tuberosum L.) is the most important horticultural crop of the world. Late blight (Phytophthora infestans (Mont.) de Bary) is the most important and devastating disease. There is no cultivar with sufficient level of resistance in Brazil being most part of production costs used for its control. Besides late blight resistance, new cultivars shou

10. Damage quantification caused by early blight in tomato / Quantificação dos danos causados pela pinta-preta em tomateiro
O cultivo do tomate (Lycopersicon esculentum Mill.) vem sendo dificultado em decorrência de pragas e doenças. Entre estas últimas, destaca-se a pinta-preta, causada por Alternaria solani (Ellis &Martin) Sorauer. Estudos epidemiológicos foram conduzidos utilizando-se o patossistema tomate pinta-preta (Alternaria solani) , em duas épocas diferentes (abril

11. Dinâmica de inóculo de Alternaria solani, efeito da densidade de plantio na intensidade da pinta preta e requeima e previsão dessas doenças em tomateiro e batateira / Alternaria solani inoculum dynamics, effect of planting density in the intensity of early and late blight and systems of those diseases in tomato and potato
Several basic and applied epidemiological aspects, relative to early (Alternaria solani) and late (Phytophthora infestans) were studied to generate useful information for the management of these diseases in tomato and potato. The basic studies were conducted aiming to determine: dynamics of A. solani conidia in the air throughout the year; the survival of th

12. Cultural characteristics and aggressiveness of isolates of Alternaria solani from potato and tomato / Características culturais e agressividade de isolados de Alternaria solani de batateira e tomateiro
Several experiments were conducted both under laboratory and greenhouse conditions to quantify putative differences between isolates of A. solani obtained from potato and tomato plants. Morphophysiological attributes and aggressiveness components were assessed. The following morphophysiological variables were measured: septation, length, width, shape, and co
