1. In vitro and in vivo control of yam dry rot nematodes using pyroligneous extracts from palm trees
ABSTRACT Dry rot of yam (Dioscorea spp.) caused by Scutellonema bradys and Pratylenchus spp. has restricted yam production in Brazil. Plant-based products can be useful reducing nematode damages. The objectives of this study were to evaluate the nematostatic and nematicidal in vitro activities of pyroligneous extracts from Cocos nucifera, Syagrus cearensis,

2. Ação do óleo essencial de Citronela (Cymbopogon nardus L) sobre o patógeno Lasiodiplodia theobromae em cachos de videira cv. Itália
RESUMO A presença de Lasiodiplodia theobromae (Podridão seca) em videiras implantadas em áreas irrigadas da região semiárida brasileira, tem mostrado elevada agressividade ao infectar várias partes das plantas. Os óleos essenciais têm apresentado eficiência no controle de doenças, tanto pela ação fungitóxica, inibindo o crescimento micelial e a

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. FATORES DA PRODUÇÃO DE MILHO EM FUNÇÃO DA ADUBAÇÃO ORGÂNICA E DE Trichoderma spp. / FACTORS OF CORN PRODUCTION AS A FUNCTION OF ORGANIC FERTILIZER AND Trichoderma spp.
A expansão da área cultivada com milho (Zea mays L.) e a utilização do plantio direto sem uma rotação de culturas adequada têm aumentado a incidência de podridões de colmo nessa cultura, devido à sobrevivência dos patógenos causadores da doença (Fusarium spp., Diplodia spp., Colletotrichum graminicola, entre outros) no solo e em restos culturais

5. Irrigation frequency and substrate volume effects in the growth and yield of tomato plants under greenhouse conditions
Tomato cropping (Solanum lycopersicum L.) under protected cultivation using substrates and drip fertigation has improved sustainable production systems especially fruit quality and plant health. However, little is known for tomato plants when considering the interaction between substrate volume and irrigation frequency. The aim of this study was to evaluate

7. Desenvolvimento de métodos de detecção precoce de infecções quiescentes de Colletotrichum spp. em mamão / Development of early detections methods of quiescent infections of Colletotrichum spp. on papaya fruits
The objetives of this study were to evaluate the methods, maturation age, temperature effect, distribution and sample size to detect quiescent infection of Colletotrichum spp. (Glomerella cingulata) on papaya fruits. At first, different methods to detect quiescent infections on immature fruits were assessed: sodium hipoclorite (1,5%), paraquat (6 ml/L a.i.),

8. Caracterização de cogumelos de Pleurotus ostreatus e Lentinula edodes produzidos em resíduos agroindustriais / Characterization of mushrooms of Pleurotus ostreatus and Lentinula edodes produced in agro-industrial wastes
Mushrooms were known and consumed by the Roman, Greek, Chinese, Egyptian and Central America civilizations. Today, more than two thousand species of potentially edible mushrooms are recognized, however, a little more than 10 are commercially exploited in the world. The consumption of mushrooms has been increasing because of the nutritional and medicinal qual

9. Resistance of potato clones to soft rot (Erwinia carotovora subsp. catorovora) / ResistÃncia de clones de batata à podridÃo-mole (Erwinia carotovora subsp. carotovora)
In order to find clones with high resistance levels to Erwinia carotovora subsp. catorovora and good agronomic traits, 234 clones from the Potato Breeding Program at the Universidade Federal de Lavras (UFLA) were evaluated. It was also evaluated the correlation between tuber dry matter content and resistance level to Ecc and identify traits for the easy eval

10. Production viability of the vine âSyrahâ in summer and winter cycles in South Minas Gerais. / Viabilidade de ProduÃÃo da Videira Syrah em Ciclos de VerÃo e Inverno no Sul de Minas Gerais
High precipitation in summer harms the grapes maturation, affecting the quality of the red wines. Therefore, it will be of great advantage to harvest the grapefruits when the climatic conditions are more favorable to the maturation, during the dry season. The present work evaluated agronomic parameters in plants and physical-chemical characteristics in fruit

11. Effects of cropping systems and previous crop on root rot pathogens of the common bean (Phaseolus vulgaris L.) / Influência de sistemas de cultivo e de sucessões de culturas em patógenos de solo do feijoeiro-comum (Phaseolus vulgaris L.)
Common bean (Phaseolus vulgaris) root rots caused by Fusarium solani f. sp. phaseoli and Rhizoctonia solani, and fusarium wilt (Fusarium oxysporum f. sp. phaseoli), are increasingly limiting factors to the irrigated winter crop in Brazil. The objective of this work was to evaluate the effect of previous crops in the conventional (CC) or no-till cropping syst

12. Agroecological management of yam crop: yield, tuber quality, control of nematodes and leaf spot diseases. / Manejo agroecológico da cultura do inhame:produtividade, qualidade, controle de nematóides e manchas foliares
Agroecologia preza os princípios da preservação e ampliação da biodiversidade dos agroecossistemas, os quais constituem as bases para se atingir a sustentabilidade do ecossistema. A cultura do inhame (Dioscorea cayennensis Lam.) vem se destacando no Nordeste brasileiro como uma alternativa promissora para os pequenos e médios produtores da região. Est
