Diclosulam e sulfentrazone no manejo das plantas infestantes na cultura da soja resistente ao glifosato e efeito da palha e precipitação sobre estes herbicidas
(Universidade Federal de São Carlos, 2014-03-21)
The Roundup Ready (RR) soybean facilitated weed management by allowing the use of glyphosate in all stages of crop development. But the continuous use of this herbicide can select resistant weed biotypes and tolerant ...
Polímeros de hidrogéis com água de reúso e de abastecimento no desenvolvimento de mudas de espécies arbóreas da floresta estacional semidecidual
(Universidade Federal de São Carlos, 2014-08-07)
The seasonal semideciduous forests from southeastern Brazil have high plant species richness, but have been strongly affected by human interferences, which let them very degraded: nowadays they are represented by small ...
Efeitos isolados e combinados dos inseticidas fipronil e tiametoxam para a abelha brasileira Melipona scutellaris Latreille, 1811 (Hymenoptera, Apidae)
(Universidade Federal de São Carlos, 2017-11-24)
Pollinators are responsible for tropical forests polinization and also have direct and indirect action on human feeding. The pollinators are majorly represented by bees. Even though, this contribution has been affected by ...
