Microorganisms are used for biological control of pests and are considered less aggressive to the environment than chemical pesticides. Research with Anticarsia gemmatalis nucleopolyhedrovirus (AgNPV) has led to the wide scale use of this pathogen in Brazil, over an estimated 2 million hectares of soybean fields annually. The spouted bed with inert particles has been used to dry pastes, such as suspensions and sludges. This work is aimed to test the application of spouted bed dryer for AgNPV biopesticide production. Experiments were carried out using two levels of airflow rate (10 e 11m/s) e air temperature (70 e 80 ºC). The airflow rate influenced positively promoting a 25% increase in the powder production efficiency. It was noted a 5% decrease in the powder production efficiency when 80 ºC was used. Higher airflow produced more humid powders and higher temperatures produced driest powders, where the average powder moisture obtained was 8,6 %. Lethal concentration for 50% of the test population (LC50) was used to evaluate the biological activity and Transmission Electron Microscopy (TEM) was carried out to evaluate biopesticide integrity. No damage was observed in the dried biopesticide and no significant difference was observed between viral biological activities of dried samples compared with a standard after 11 days of infection.These results indicate that spouted bed can be considered a viable alternative for baculovirus biopesticide formulation production. |
