Over the last few years, considerable effort has been spent by Embrapa in construction of a plant disease database representative enough for development effective methods automatic detection and recognition. In October 2016, this database, called PDDB, had 2326 images 171 diseases other disorders affecting 21 species. PDDB size, although considerable, is not to allow use powerful techniques such as deep learning. order increase its each image was subdivided according certain criteria,...
Papaya is susceptible to fungal deterioration and the use of essential oils (EOs) emerges as a promising alternative fungicides, which causes environmental human health problems. To evaluate antifungal activity their major constituents in controlling papaya pathogens, following vitro assessments were conducted: I) screening seven EOs regarding activity; II) determination minimum inhibitory concentration (MIC) most EOs; III) analysis chemical composition effective oils; IV) evaluation...
Abstract Botryosphaeria dothidea is the major pathogen of mango in Brazil, causing stem‐end rot, which causes significant losses during transportation and storage. The current strategy to control this particular disease using synthetic fungicides has been ineffective, leaving residues fruit. objective research was study effect physical treatments, with hot water rinse brushing ( HWRB ) ultraviolet C irradiation UV ‐C), individually combination, rot mango. Physicochemical parameters,...
Abstract The present study investigated the potential of benzo‐thiadiazole‐7‐carbothioic acid S ‐methyl ester (BTH) to protect postharvest melons var. ‘Orange Flesh’ from fruit rot caused by Fusarium pallidoroseum . It was noticed that melon fruits immersed in BTH and postinoculated with fungus presented same pattern disease incidence/severity activity defence‐related enzymes superoxide dismutase, ascorbate peroxidase, guaiacol phenylalanine ammonia‐lyase, β‐1,3‐glucanase controls,...
RESUMO O bolor verde é a principal doença de frutos cítricos pós-colheita. Produtos e processos alternativos para controle doenças plantas vêm sendo cada vez mais requeridos. objetivo deste trabalho foi avaliar atividade antifúngica óleos essenciais sobre Penicillium digitatum em laranjas, isoladamente ou combinação com tratamento térmico. Para tanto, um isolado do fungo submetido, in vitro, diferentes concentrações dos canela, capim-limão palmarosa, meio cultura BDA, avaliada também...
Efficiency of 1-MCP on postharvest life whole and fresh-cut cantaloupe melons was evaluated. Melons were treated with doses varying from 0 to 900 nl.L -1 in order define the best concentration 1-MCP. Flesh softening main characteristic affected all experiments delay according dose, although differences between above 300 not significant. Respiration ethylene evolution rates reduced both CO 2 peaks delayed trials melons. doubled at ambient temperature (from 1 weeks). Treated acceptable for 27...
Abstract Conventional detection and identification of the fungi causing postharvest diseases in fruits are time‐consuming, laborious, can only be performed after manifestation symptoms. In this work, an alternative method based on headspace analysis, which allows early species frequently found papaya fruit, is presented. Volatile compounds four vitro cultures ( Alternaria alternata , Colletotrichum gloeosporioides Fusarium solani Lasiodiplodia theobromae ) were extracted using solid‐phase...
Melon (Cucumis melo) is the most exported fruit in Brazil (224,000 tonnes), and production increased by 10% past growing season.Currently, 22,000 ha are devoted to its cultivation country, has reached above 500,000 tonnes.The concentrated on northeast semiarid area, particularly Chapada do Apodi, between Rio Grande Norte Ceará States.Rio State responsible for 70% of
Existe uma demanda, na região semiárida produtora de uvas no Submédio São Francisco, por medidas sustentáveis controle doenças pós-colheita, vez que o modelo atual revestimento caixas com polietileno alta densidade, associado ao metabissulfito sódio, não tem se mostrado eficiente dos fungos ocorrem região. O objetivo desse trabalho foi estudar um da podridão Aspergillus em 'Thompson Seedless' meio modificação atmosfera, pelo envolvimento uva bolsões poliamida. Comparou-se bolsão poliamida...
O mercado consumidor está exigindo alimentos sem a presença de resíduos agrotóxicos. Assim, o trabalho teve como objetivo avaliar controle do bolor verde, em laranjas-Pera, com agentes biocontrole (Bacillus subtilis e Bacillus licheniformis, (QST 713)), associados ou não ao tratamento térmico. Para tanto, os frutos foram adquiridos "packinghouse" antes processamento, sendo lavados desinfestados hipoclorito sódio. Os submetidos esses tratamentos armazenados, por 11 28 dias, temperatura 10 ºC...
Abstract Green mould, caused by Penicillium digitatum , is the major postharvest disease of citrus in all producing countries. The control this carried out fungicides treatments, which can leave toxic residues fruits. Therefore, interest cleaner technologies and alternatives to use fungicides, such as biopesticides, has grown recent years. Conyza canadensis an herbaceous weed spread over world, contains compounds have significant activity against P . Thus, present research aimed evaluate...
Objetivou-se neste trabalho avaliar o efeito de 1-MCP (300 nL.L¹) nas alterações fisiológicas que ocorrem durante amadurecimento do melão, tipo Orange cv. Flesh e sua influência no controle da podridão causada por Fusarium pallidoroseum, em dois ambientes armazenamento, sem refrigeração (29 ± 1 ºC umidade relativa 65 2 %) refrigerado (10 90 3 15 dias nove adicionais condição ambiente. Avaliouse a atividade respiratória, produção etileno, perda matéria fresca, cor casca polpa, firmeza pH,...
As podridões pós-colheita constituem fator de risco nas exportações. No entanto, o número produtos registrados para tratamento frutos melão (Cucumis melo) é reduzido. Objetivou-se neste trabalho avaliar a influência dos fungicidas thiabendazole, azoxystrobin e imazalil 30, 10 400g i.a/100 l, no desenvolvimento Fusarium pallidoroseum estudar efeito deles, combinados à refrigeração, controle podridão em melão. Thiabendazole inibiram 100% do crescimento micelial esporulação F. pallidoroseum,...
