15. ResistÃncia das leveduras Kluyveromyces marxianus e Saccharomyces cerevisiae ao fungicida Benomyl
Investigations on the toxic compound-resistant phenotypes by microrganisms are regarded as relevant within the bio-technological, clinic and farming fields. In this work, we aimed to identify the co-relation between the resistance levels of yeast cells to the fungicide Benomyl and the presence of two yeast genes already related to have any influence

18. Controle alternativo da ramulose do algodoeiro via utilização de óleos fixos e essenciais
Colletotrichum gossypii South. var. cephalosporioides Costa is the causal agent of one of the most important cotton diseases, the ramulosis. The disease is characterized by necrotic lesions on leaves and petioles mainly on young leaves. As the disease progresses, shortening of the internódios, apical death and overbudding are also observed. The main way of

19. Insecticide and fungicide activity of the ethanolic extracts of Pachira aquatica in Aubl Hypothenemus hampei (Ferrari) and Fusarium sp / ATIVIDADE INSETICIDA E FUNGICIDA DO EXTRATO ETANÓLICO DE Pachira aquatica AUBL SOBRE Hypothenemus hampei (FERRARI) E Fusarium sp
The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae), is considered as one of the principals plagues of the coffee tree, attacking the fruits all maturation phases. It possesses a short biological cycle and has a great capacity of proliferation, thus causing a phytossanitary problem in all the producing regions of coffee. Initial ef

20. Controle de Guignardia citricarpa, agente causal da Mancha Preta dos Citros / Control of Guignardia citricarpa, causal agent of Citrus Black Spot
Citriculture is an extreme important rural activity in social and economical national context in Brazil. Orange is 49% of total brazilian fruit production. However, thousands of tons are lost due to the action of phytopathogens annually. The Black Spot of Citrus (BSC) is responsible for great lost in various citrus producers regions all around the world, bei

23. Controle de Tetranychus urticae Koch com fungos entomopatogênicos. / Control of Tetranychus urticae Koch with entomopathogenic fungi.
Among 45 isolates of hyphomycetes tested against Tetranychus urticae, 8 Beauveria bassiana and 4 Metarhizium anisopliae isolates caused mortality >80 and 90%, respectively, 5 days after inoculation with 5x10 7 conidia/mL. Hirsutella sp. caused 73% mortality at a concentration of 1.7x10 7 conidia/mL. Eighty to 100% of cadavers infected by B. bassiana or M. an

24. Succession of Indigenous Pseudomonas spp. and Actinomycetes on Barley Roots Affected by the Antagonistic Strain Pseudomonas fluorescens DR54 and the Fungicide Imazalil
In recent years, the interest in the use of bacteria for biological control of plant-pathogenic fungi has increased. We studied the possible side effects of coating barley seeds with the antagonistic strain Pseudomonas fluorescens DR54 or a commercial fungicide, imazalil. This was done by monitoring the number of indigenous Pseudomonas organisms and actinomy
