| As sementes, estacas, bulbos, tubérculos, etc., são órgãos de propagação vegetal e eficientes veículos de disseminação de fitopatógenos em campos agrícolas. Como as sementes contribuem com aproximadamente 90% para a propagação das culturas, muitos fungos, bactérias, virus e alguns fitonematóides podem apresentar-se associados as mesmas, causando severos danos as culturas. Estes fitopatógenos, em condições favoraveis, sobrevivem nas sementes de um ano para outro; ou por período mais longo durante o armazenamento. São apresentados no trabalho os danos causados por sementes infectadas ou contaminadas, os meios de disseminação de fitopatógenos pelas sementes e como evitar a introdução de doenças na região. Com relação a colheita, dois aspectos básicos devem... |

| Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the... |

| Marine mollusk aquaculture has more than doubled over the past twenty years, accounting for over 15% of total aquaculture production in 2016. Infectious disease is one of the main limiting factors to the development of mollusk aquaculture, and the difficulties inherent to combating pathogens through antibiotic therapies or disinfection have led to extensive research on host defense mechanisms and host-pathogen relationships. It has become increasingly clear that characterizing the functional profiles of response to a disease is an essential step in understanding resistance mechanisms and moving towards more effective disease control. The Manila clam, Ruditapes philippinarum, is a main cultured bivalve species of economic importance which is affected by... |

| Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correctly identifying the fungus Fusarium guttiforme, agent of the pineapple fusariosis, have led to the search for new methodologies, and for this we developed a new reliable molecular method to detect it. For diagnostic purposes, real-time PCR of elongation factor gene 1-α (ef1) was used to rapidly, specifically and sensitively diagnose F. guttiforme. A pathogenicity test was conducted with slips of the... |

| The present work was conducted to evaluate the efficiency of different insecticides for the control of Stiphra robusta Mello Leita, 1939, a severe pest of Eucalyptus citriodora, in Petrolina,PE, Brazil. The experiment was conducted in a randomized complete-block design with seven treatments, four replications, and fourllowing insecticides and respective dosages: a. control (no insecticide); b. endosulfan 35 EC 2.5 l/ha; c. triazofos 40 BR, 1.5 l/ha; d. endosulfan + methyl parathion. 2.0 l/ha; e. deltamethrin 2.5 EC, 0,4 l/ha; f. fevalerate 30 EC, 0.3 l/ha, and methyl parathion 60 Em, 1.5 h/ha. The percentage of efficency was obtained by most efficient treatments were fenvalerate 30 EC (83.72% of control) and deltamethrin 2.5 EC (79.42% of control) which... |

| Agronomic evaluation of Amarelo melon lines resistant to WMV-1, 1985> Nine WMV-resistant Amarelo melon lines obtained from the Centro Nacional de Pesquisa de Hortalicas's melon breedingr program and the WMV-susceptible Amarelo were field sown in 20 Aug 85 com a distrophic sandy oxisol, pH = 6.1 and M.O. = 1%, in Petrolina, PE, Brazil and harvested on 30 Oct 85. Mean temperature in oC (MT), Rainfall in mm (FR) and Relative humidity in % (RH) were as follows: (Aug (20-31): MT = 24.9 RF = 0.0 RH = 62.2; Sep: MT = 27.6 RF = 0.9 RH = 58.0; Oct: MT =27.7 RJH =14.1 RH =58.8. Plots were arranged in a randomized complete block design with ten treatments and four replication. Area/treatment was 80 m2, each plot consisting of four ten-hill row, twwo planta/hill.... |
