Several different plant extracts have been evaluated with respect to their antimicrobial effects against oral pathogens and for reduction of gingivitis. Given that a large number of these substances have been associated with significant side effects that contraindicate their long-term use, new compounds need to be tested. The aim of this study was to assess the short-term safety and efficacy of...

The two-spotted spider mite, Tetranychus urticae, causes damage to crops grown in northeast Brazil. adoption of biological control methods and curative (plant-based insecticides) is an essential practice for pest management agroecological systems. Therefore, the aim present study was investigate chemical properties, toxicity, ovicidal activity oils (EOs) from Lippia sidoides, Croton rhamnifolio...

Pelargonium zonate spot virus (PZSV) is identified recently in tomato plants in the United States. To develop serological diagnostic tools for the detection of this virus, the production of good quality antibodies is a necessity. The coat protein (CP) gene of a California isolate of PZSV was cloned into a bacterial expression vector (pTriEX-4 Ek/LIC). The plasmid pTriEX-4-PZSV-CP was transforme...

Continual exposure to 1.5 ml l ethylene caused 100% petal abscission within 2 h from detached flowers of Pelargonium peltatum (L.) ‘Pink Blizzard’ (ivy geranium) harvested just after the stigmatic lobes had separated. When flowering plants were first pretreated for 2 h with 1 ml l 1-MCP, ethylene-induced petal abscission was completely inhibited. However, the effect was transient, since percent...

OBJECTIVES The antiplaque and antigingivitis effect of Lippia Sidoides (LS) was evaluated in this in vivo investigation. MATERIAL AND METHODS Twenty-three subjects participated in a cross-over, double-blind clinical study, using 21-day partial-mouth experimental model of gingivitis. A toothshield was constructed for each volunteer, avoiding the brushing of the 4 experimental posterior teeth i...
