2. COPPER OXYCHLORIDE APPLIED ALONE TO CONTROL CITRUS BLACK SPOT
RESUMO A Mancha Preta dos Citros causada pelo fungo Phyllosticta citricarpa é uma doença que causa lesões em frutos e queda prematura em estágios mais severos. O uso de fungicidas sistêmicos é a principal medida de controle, porém a busca por um controle alternativo pode envolver a aplicação de fungicidas cúpricos isoladamente, em intervalos reduzi

3. Chemical products induce resistance to
Xanthomonas perforans in tomatoThe bacterial spot of tomato, caused by
Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolarBraz. J. Microbiol.. Publicado em: 21/07/2015

4. Uptake of seed-applied copper by maize and the effects on seed vigor
Seed treatment is a low-cost and efficacious method to deliver a diversity of compounds to field crops. This study evaluated the uptake of seed-applied Cu by maize and the effect on seed vigor. The treatments were composed of a control (untreated seeds) and five dosages of Cu: 0.11, 0.22, 0.44, 0.88 and 1.76 mg Cu seed–1, applied as cuprous oxide and coppe

5. Control of cashew black mould by acibenzolar-S-methyl
Black mould is one of the most important foliar diseases of dwarf cashew plants in coastal zone of northeastern Brazil. In order to develop a reliable method to control this disease, a field experiment was conducted in the 2008/2009 season to evaluate the effect of acibenzolar-S-methyl (ASM) on disease severity at three different intervals with two, four and

6. Severidade da pinta preta em genótipos de tomateiro cereja e avaliação de fungicidas e produtos alternativos no crescimento micelial e germinação de Alternaria tomatophila
Among the fungal diseases that affect tomato, the black spot, caused by the fungus Alternaria tomatophila, is one of the most important of the crop. The use of resistant varieties and products that can induce resistance emerge as an option of low cost and less damage to the environment when compared to the use of agrochemicals. Thus, our objective with this

8. Caracterização de isolados de Xanthomonas axonopodis pv. begoniae e avaliação de defensivos agrícolas no controle da mancha foliar bacteriana em begônia / Characterization of Xanthomonas campestris pv. begoniae and evaluation of pesticides in the control of bacterial leaf spot and blight of begonia
Xanthomonas campestris pv. begoniae (Xab) is the causal agent of bacterial leaf spot and blight of begonias. The variability of Brazilian strains of Xab is not known. Neither is known about the effectiveness of pesticides to control bacterial leaf spot and blight of begonias. This study aimed to characterize biochemical and biologically twenty Xab isolates c

10. Evaluation of some essential oils for their toxicity against fungi causing deterioration of stored food commodities.
During screening of essential oils for their antifungal activities against Aspergillus flavus, the essential oil of Cymbopogon citratus was found to exhibit fungitoxicity. The MIC of the oil was found to be 1,000 ppm, at which it showed its fungistatic nature, wide fungitoxic spectrum, nonphytotoxic nature, and superiority over synthetic fungicides, i.e., Ag
