1. Phytotoxicity and physiological changes in Schinus terebinthifolius Raddi under simulated 2,4-D drift and dicamba
ABSTRACT The use of auxin mimics herbicides in agriculture is widespread in a great diversity of crops. The indiscriminate use of herbicides can cause adverse effects in the plants. Among the plant species that stand out for being highly competitive and resistant to biotic and abiotic stresses, it is the brazilian peppertree (Schinus terebinthifolius Raddi.)

2. Extracts of the Native Brazilian Tree Garcinia gardneriana Inhibit Urediniospore Germination of Coffee Leaf Rust Fungus
The fungal Hemileia vastatrix is the causal agent of coffee leaf rust, one of the worst and devastating disease in coffee cultures worldwide. As a result of our research on natural products for the development of novel agrochemicals, we found that the hexane extract from leaves of the Brazilian medicinal plant Garcinia gardneriana, at 500 μg mL-1, inhibited

3. Tolerance of cowpea cultivars to pre-emergence application of sulfentrazone
ABSTRACT Improved methods of weed control are required to support expansion of large-scale cowpea cultivation in mid-west Brazil. With the aim of testing our hypothesis that the tolerance of cowpea cultivars to sulfentrazone is dose- and genotype-dependent, we assessed the effects of increasing doses (0, 250, 500 and 1,000 g ha-1 of sulfentrazone) on the cul

4. SYNTHESIS AND PHYTOTOXIC PROFILE OF A NEW TETRAOXANE DESIGNED FROM A COMMERCIAL AUXIN
Modern agriculture relies on the massive use of agrochemicals, including herbicides. Despite their effectiveness, a continuous use of herbicides sharing the same target has resulted in the selection of weed biotypes resistant to such chemicals. To cope with this problem, the development of new herbicides is an urgent requirement. In this work we applied the

5. DISINFECTION PROTOCOL AND IN VITRO GERMINATION OF SEEDS OF Dalbergia nigra
ABSTRACT The Atlantic Forest is a biome that has suffered anthropic actions, such as the extraction of hardwood, which can lead to the extinction of endemic species of great economic and ecological value, such as Dalbergia nigra. In this perspective, large-scale multiplication studies are necessary to contribute to the conservation of this species. The objec

6. Synthesis of Glycerol-Derived 4-Alkyl-Substituted 1,2,3-Triazoles and Evaluation of Their Fungicidal, Phytotoxic, and Antiproliferative Activities
Herein, the synthesis of nine novel glycerol-derived 4-alkyl-substituted 1,2,3-triazoles, using the CuI-catalyzed alkyne-azide cycloaddition reaction as the key step, is reported. The triazoles were characterized by infrared and nuclear magnetic resonance (NMR 1H and 13C) spectroscopy and mass spectrometry. The nine prepared compounds were evaluated with reg

7. Composition, antioxidant properties, and biological activities of the essential oil extracted from Ocotea diospyrifolia (Meisn.) Mez.
The article has aimed to characterize the essential oil extracted from Ocotea diospyrifolia (Meisn.) Mez. leaves, in terms of its chemical composition and antioxidant, hemolytic, and phytotoxic potentials, as well as its toxicity against Artemia salina. The major constituents identified by CG-MS were d-elemene, spathulenol, and b-atlantol. When screened for

8. Glyphosate as Growth Regulator for Bahiagrass and Broadleaf Carpetgrass
RESUMO: Objetivou-se neste trabalho avaliar o efeito do uso do herbicida glyphosate como regulador de crescimento em grama Batatais e São Carlos. Os experimentos foram conduzidos em casa de vegetação no delineamento inteiramente casualizado com dez doses de glyphosate: 0; 5,625; 11,25; 22,5; 45; 90; 180; 360; 720; e 1.440 g a.e. ha-1 e quatro repetições

9. Phytotoxic potential of aqueous leaf extract of Tocoyena formosa and Rudgea viburnoides
ABSTRACT Plants have organic components produced as secondary metabolites able to positively or negatively interfere on normal development of other species. The objective of this research was to determine the phytotoxic effect of aqueous leaf extract from two species Rubiaceae family: Tocoyena formosa and Rudgea viburnoides on the germination and initial dev

10. Herbicide selectivity for potato crop
RESUMO Estudos sobre seletividade de herbicidas para a cultura da batata são poucos, especialmente em condições brasileiras. Por isso, objetivou-se estudar a ação fitotóxica de diferentes herbicidas para a cultura da batata, cv. Agata. Dois experimentos foram desenvolvidos em área de produção comercial, no delineamento experimental de blocos ao acas

12. Ecotoxicology of Pig Slaughterhouse Waste Using Lactuca sativa L., Raphanus sativus L., and Oryza sativa L.
ABSTRACT Pork is the most consumed animal protein around the world. The production levels are significant, which results in the generation of large amounts of slaughter waste. Such waste is often disposed of improperly in agricultural areas, causing environmental imbalance by the contamination of soil and water sources with metals and pathogenic organisms. T
