Demand from the use of products for sustainable agriculture and causing less impact on the environment is increasingly larger. Thus, the use of biological control is an alternative to reduce the use of pesticides and the risks they entail. The fungus Trichoderma harzianum is an example of effective biological control against the pathogen Sclerotinia sclerotiorum, which affects many crops and brings production losses of up to 100%. However, the use of this biocontrol fungus may encounter some problems, for example, fungal stress biotic and abiotic factors, degração by UV light, temperature and lack of moisture. One solution to this problem would be the microenpcaulação biological control of fungus in microparticles. Thus, this work aims to develop microparticles of calcium alginate as a carrier of fungal system, characterize the micro system through physicochemical methods, analyze the biological activity of Trichoderma harzianum fungus free and microenpcasulado on the fungus Sclerotinia sclerotiorum order to obtain information on the carrier system, in addition to soil microbiota assessment to verify the effects of carrier systems on the bacterial community, for the development of safer and effective alternatives to control the pathogen fungus, thus reducing environmental impacts.
