Development of alginate-montmorillonite-starch with encapsulated Trichoderma harzianum and evaluation of conidia shelf life

Biological control agents, such as Trichoderma harzianum, are widely used in sustainable agriculture. However, commercialisation and mass production of biocontrol products have remained a challenge, especially in viability and efficiency in field application. The encapsulation method has emerged as...
