The continuous use of pesticides protecting plants from diseases can result in several damages due the environmental pollution and food residues. Thus, it is necessary the search for new plant diseases control technology. The objective of this study was to evaluate the in vitro antimicrobial activity against Alternaria solani and Xanthomonas vesicatoria and the control of early blight and bacterial spot on tomato plants, using stable formulation, as soluble powder, from Pycnoporus sanguineus. To determine the shelf life, the soluble powder was kept at 40 oC during 0, 60, 120 and 180 days and assayed with five concentrations (0, 50, 100, 150 and 200 mg L-1). When the shelf life and the best concentrations were defined, it was evaluated the time-interval of...

Medicinal plants have active compounds in their composition produced from secondary metabolism, which can have fungistatic and /or fungitoxic action on the development of phytopathogens. The objective of this work was to study the effect of aqueous extracts of Ocimum basilicum, Baccharis trimera and Cnicus benedictus on mycelial growth of plant pathogens. The experimental design had three medicinal plants, six concentrations of each aqueous extract (1%, 5%, 10%, 15%, 20%, 25% and 50%), five fungus - Alternaria alternata, Colletotrichum graminicola, Phytophthora sp., Rhizoctonia solani and Sclerotinia rolfsii, and four repetitions for each treatment. The variables analyzed were: inhibition of mycelial growth, mycelial growth and area under the curve of...

Various methods are been used to control post-harvest diseases of tomato fruits. With the increasing restrictions on the use of fungicides, due the food safety and environmental impacts, the use of alternative methods and biological control of postharvest diseases have been stimulated. The aim of this work was to investigate the effect of alternative products in post-harvest treatment of tomato “Delta” and “Debora” produced under two cropping systems: intermediate (IS) and conventional system (CS). The components evaluated were the reduction of fresh mass, pH, soluble solids (SS), titratable acidity (TA) and the pathogens incidence after being treated by immersion with acibenzolar-S-methyl (ASM), Azadirachta indica crude extract, citric biomass extract and...

Curcuma spp. (turmeric) has been used since ancient days in popular medicine and gastronomy. Many of its bioactive compounds have just recently been identified and characterized as potential source of new medicines. In this review will relate aspects of cultivated turmeric (Curcuma longa L.), including taxonomy, chemical composition, production and processing, and biological activities such as the action against fungi, bacteria, nematodes, protozoa and viruses, including those of importance for human health, agriculture and food science.

Controle de doenças foliares do milho com fosfito de potássio
Provedor de dados: 22
Autores: da Silva, João Batista Gonçalves Dias; Schwan-Estrada, Kátia Regina Freitas; Tessmann, Dauri José; Moterle, Lia Mara; da Silva, Camila Rocco.
Esse estudo teve como objetivo avaliar a eficiência da aplicação de fosfito de potássio (PHOS UP PK 28-26®) em diferentes doses e estádios de crescimento da planta para o controle dePhaeosphaeria maydis, Cercospora zeae-maydis e Exserohilum turcicum na cultura do milho 2a safra, bem como a produtividade dos híbridos. Dois experimentos distintos com fosfito, testemunha sem aplicação e fungicida epoxiconazole + piraclostrobina (Ópera®), foram conduzidos nas safras agrícolas, 2008/2009 e 2010, no mesmo local. O delineamento experimental foi em blocos completos, com tratamentos ao acaso e quatro repetições. Foram avaliadas a severidade das doenças com escala diagramática e a produtividade. Foram observados diferentes comportamentos de acordo com a cultivar e...
