1. Algal polysaccharides as source of plant resistance inducers
Algal compounds exhibit great potential to enhance plant growth and resistance to abiotic and biotic stresses. This review focuses on aspects concerning the physical-chemical properties, function and biological activity of macroalgae polysaccharides. Updated results of the main poly- and oligosaccharides studied for the control of plant diseases are discusse

3. Release of Trichogramma pretiosum (Hym.: Trichogrammatidae) and evaluation of Trichogrammatidae on egg masses of Spodoptera frugiperda (Lep.: Noctuidae) in corn / LIBERAÇÃO DE Trichogramma pretiosum (Hym.: Trichogrammatidae) E AVALIAÇÃO DE Trichogrammatidae EM POSTURAS DE Spodoptera frugiperda (Lep.: Noctuidae) NA CULTURA DO MILHO
Fall armyworm, Spodoptera frugiperda (J.E. Smith), is considered the major pest of corn. In general, the control of larvae is achieved with insecticides application, which can cause several environmental problems. In search of alternative control methods, egg parasitoids of the genus Trichogramma have been used in applied biological control programs, since t

4. Produção orgânica de alface americana fertirrigada com biofertilizantes em cultivo protegido / Organic yield of iceberg lettuce fertigated with biofertilizers, in organic protected cultivation
Biofertilizers have positive effects on nutrition, postharvest attributes and crop protection, but little is known about its characteristics and real efficiency. Furthermore, application rates commonly used throughout the crop cycle does not attend the growing culture needs satisfactorily. Thus, this study aimed to evaluate the effect of biofertilizers appli

7. Avaliação da citotoxicidade, genotoxicidade e dos efeitos protetores do extrato de Anacardium occidentale L. in vitro
The use of vegetable species in order to treat and cure diseases leads us back to the beginning of our civilization, to the moment in which man started a long journey of handling, adaptation and modification of these natural resources for his own benefit. Among the plants that continue to be a great source of medicine to the humanity is the Anacardium occide

8. 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

9. The seed industry in the brazilian plant variety protection environment / A empresa de sementes no ambiente de proteção de cultivares no Brasil
The intellectual property rights in plants has been an issue globally discussed since the beginning of the last century, resulting in the adoption of protection systems and patents. Besides the production and trade of seed laws, there is other two forms of settling down controls on seeds: the biological, in that is possible to control the pollination of the

12. Potential Role of Pathogen Signaling in Multitrophic Plant-Microbe Interactions Involved in Disease Protection
Multitrophic interactions mediate the ability of fungal pathogens to cause plant disease and the ability of bacterial antagonists to suppress disease. Antibiotic production by antagonists, which contributes to disease suppression, is known to be modulated by abiotic and host plant environmental conditions. Here, we demonstrate that a pathogen metabolite func
