UFU develops microencapsulation of Trichoderma asperellum for microbiological fungicides
Jan. 25, 2019
By Leonardo Gottems, Reporter for AgroPages
A study was conducted the Federal University of Uberlândia (UFU) in the Brazilian state of Minas Gerais on how to improve the economic viability of the use of biological pesticides in agriculture.
According to the research, using the microencapsulation of the fungus Trichoderma asperellum can prolong the life of microbiological fungicides.
The study, which was carried out by the UFU Graduate Program in Food Engineering, aimed to determine how the fungus, which has large plant growth properties, could be used to solve the major problem related microbiological fungicides, which is their short shelf life. Through using miroencapsulation, a physical barrier is formed around the conidia, which are spores responsible for the reproduction of some fungi while the external environment, such as moisture, oxygen and heat, can also affect the stability of the fungicide.
"Our main goal was to create a methodology that will favor the production and storage of microbiological fungicides, since the world’s population is increasingly concerned about the environment and the purity of food," said researcher Alinne Brandão Braga, who was guided by Professor Eloízio Júlio Ribeiro.
The researchers were able to determine the ideal drying air temperature and concentration of the protective agent to produce the microparticles. "The results demonstrated that microencapsulated conidia can be used to increase the shelf life and stability of fungicides, and we aim to create methodologies for sustainable agriculture," Braga said in conclusion.
