1. SYNTHESIS OF GLYCEROL-FLUORINATED TRIAZOLE DERIVATIVES AND EVALUATION OF THEIR FUNGICIDAL ACTIVITY
The control of fungal species in agriculture is mainly conducted with the use of contact or systemic fungicides. However, environmental and human health concerns and increased resistance of fungal species to existing fungicides have increased the pressure on researchers to find new active ingredients for fungal control which present low toxicity to non-targe

2. Morphological, pathogenic and genetic diversity of Botrytis cinerea Pers. in blackberry cultivations in Colombia
Resumo A amora-preta (Rubus glaucus Benth) é uma das frutas mais importantes e com a maior projeção comercial da Colômbia. Os fatores que mais afetam sua produção são o ataque de doenças e a pouca informação sobre o seu controle. Uma das doenças mais limitantes no cultivo é o mofo cinzento, produzido pelo fungo Botrytis cinerea. Esta pesquisa ap

3. Performance of chlorothalonil levels and spraying intervals on Asian rust control and soybean grain yield
RESUMO Em experimento conduzido no campo, na safra 2017/18, com a cultivar Syn 1561 IPRO, avaliou-se a interação de doses e de intervalos entre aplicação do fungicida clorotalonil no controle da ferrugem asiática da soja, causada por Phakopsora pachyrhizi. A primeira aplicação do fungicida foi realizada no estádio V8, 44 dias após a emergência, com

4. CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS
ABSTRACT Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control. Spray bar support systems, such as the air curtain (Vortex®) and the use of nozzles along the bar (Dropleg®), stand out as an

5. Avaliação do uso de elicitores de resistência bióticos e abióticos contra a antracnose na videira (Vitis labrusca L.)
RESUMO A antracnose da videira é uma doença causada pelo fungo Elsinoe ampelina sendo responsável por grandes danos na cultura. A proteção de plantas por meio da resistência induzida tem sido visualizada como uma importante medida de controle alternativo. Os elicitores de resistência estimulam uma série de reações no hospedeiro, para a produção d

6. Addition of mancozeb to the fungicide mixtures DMI + QoI and SDHI + QoI on the control of wheat leaf blights
RESUMO As manchas foliares do trigo causadas por Drechslera siccans e, principalmente, D. tritici-repentis são de difícil controle pelas misturas de fungicidas sítio específicos. Devido ao desenvolvimento da resistência, o uso das misturas duplas de sítio específicos apresenta controle inferior a 50%. Em experimento conduzido no campo com a cultivar d

7. Quitosana associada com extratos vegetais no controle pós-colheita de antracnose em mamão ‘formosa’
RESUMO O uso excessivo de produtos químicos na cultura do mamão (Carica papaya) coloca em risco a eficácia de fungicidas, em razão dos problemas de resistência dos patógenos a esses produtos, além da possibilidade de resíduos tóxicos colocarem em risco a saúde humana e o ambiente. Diante disto, o presente trabalho teve por objetivo avaliar a eficá

8. Resistance of Botrytis cinerea to fungicides controlling gray mold on strawberry in Brazil
ABSTRACT The aim of this study was to evaluate the resistance of Botrytis cinerea to the fungicides currently used for its control in Brazil. Isolates of the fungus were collected from different strawberry-producing fields in the states of Espírito Santo, Minas Gerais, and São Paulo, Brazil. First, a total of 183 isolates were identified at the species lev

9. Is the emergence of fungal resistance to medical triazoles related to their use in the agroecosystems? A mini review
Abstract Triazole fungicides are used broadly for the control of infectious diseases of both humans and plants. The surge in resistance to triazoles among pathogenic populations is an emergent issue both in agriculture and medicine. The non-rational use of fungicides with site-specific modes of action, such as the triazoles, may increase the risk of antifung

10. Yield, market quality, and leaf spots partial resistance of interspecific peanut progenies
Development of leaf spots resistant runner peanut cultivars is one of the major demands in Brazil. In the 2009/10 crop season, 12 pre-breeding progenies (LPM) were selected out of 380 plants of an interspecific BC1F3 population for leaf spots resistance and agronomic traits. In the 2010/11, the 12 LPMs were evaluated for leaf spots resistance, without fungic

11. Fitness components of Monosporascus cannonballus isolates from northeastern Brazilian melon fields
Monosporascus root rot and vine decline caused by Monosporascus cannonballus is one of the most important melon yield-limiting diseases in northeastern Brazil. This study investigated the fitness components of 57 isolates of M. cannonballus obtained from Brazilian melon fields by evaluating: i) their mycelial growth rate (MGR), and perithecia and ascospore p

12. Baseline sensitivity of Brazilian Mycosphaerella fijiensis isolates to protectant and systemic fungicides
Black Sigatoka caused by Mycosphaerella fijiensis is a foliar disease that affects banana plants and large amounts of fungicides are required to prevent crop losses. Intensive applications of single-site fungicides can select for fungicide-resistant isolates. The objective of this study was to assess the sensitivity of 60 isolates of M. fijiensis to commonly
