Spray drift and efficacy from glyphosate and 2,4-D applications with adjuvants
Alves, Guilherme Sousa; Cunha, João Paulo Arantes Rodrigues da; Landim, Thiago Nunes; Silva, Sérgio Macedo; Alves, Thales Cassemiro; Goulart, Caio SilvaWeed plants are one of main factors that affect the production of oilseed crops. Their management have been based on chemical control with herbicides, like glyphosate and 2,4-D, due to usefulness and efficiency of applications. However, their use must be managed correctly to mitigate the spray drift. Therefore, this study aimed to evaluate efficacy and spray drift from glyphosate and 2,4-D applications with adj...

Fertilization and cropping systems: performance and oil content of basil varieties
Silva, Adeláide Siqueira; Oliveira, Roberta Camargos; Luz, José Magno Queiroz; Silva, Sérgio Macedo; Blank, Arie Fitzgerald; Alves, Mércia FreitasSweet basil (Ocimum basilicum L.) is an aromatic and medicinal crop that produces metabolites rich in chemical constituents for various purposes. The composition of the essential oil is variable due to external factors during production, such as fertilization and the environment, and the oil concentration may vary even among the genotypes of a species. For sweet basil mores studies are needed to clarify underst...
Control of Dalbulus maidis in maize crop with electrostatic spraying
Marques, Rodrigo Santos; Rodrigues da Cunha, João Paulo Arantes; Alves, Guilherme Sousa; Alves, Thales Cassemiro; Silva, Sérgio MacedoAmong the pests that attack the maize, the maize leafhopper, which causes direct damages by sap-sucking and indirect ones, stands out as being a vector of pathogens and viruses, and can cause losses of up to 100% of the production. An alternative to improve the chemical control of this pest is the use of electrostatic spraying technology. However, there is no research support. This study aimed to evaluate the d...
