Abstract

The sugar cane is one of the most important crops of Brazilian agribusiness and each year its planting area grows significantly. With the publication of laws prohibiting the burning of sugar cane in São Paulo, it's growing every year the number of hectares of the plant that has been harvested mechanically. This growing area of green sugar cane harvest reflects the growth rates of pests of crop, because the fire is no longer a means of natural control. The sugar cane borer Diatraea saccharalis and weevil Sphenophous levis are pests currently of concern in the culture due to serious losses and damage they cause. Microbial control with fungal becomes an alternative as it generates a more effective control over the years and also because of their appearance environmentally beneficial. The fungus Beauveria bassiana and Metarhizium anisopliae are the main fungi produced and used on a commercial scale in Brazil. However, in terms of formulation there is still a lot to be done. The formulation is one of the most important steps in standardizing the biopesticide and of great importance to its commercial viability, because it will ensure greater adherence of the product in the insect or plant providing greater efficiency in the implementation and control. Another important factor in the formulation is to ensure greater stability of the product on the shelf so it can be stored for a longer time maintaining its main characteristics such as viability and virulence of conidia on the insect to be controlled. Among the technologies currently available microencapsulation of conidia using biodegradable polymers shows promise. Thus, one of the objectives of this project is to obtain microformulations based on fungi (B. bassiana and M. anisopliae) which are economically viable, stable, efficient and have a broad potential for disease control and on various pests of economic importance crops in Brazil.
