Abstract

The present invention relates to a Trichoderma-derived selenium nanoparticles foliar fertilizer which reduces crop fungal diseases and toxin contamination. For the first time, a new type of agricultural composition was disclosed, which is mainly obtained by mixing Trichoderma harzianum culture with selenite, which has a good fungistatic effect. The inventors also screened and obtained a harzianum strain with excellent effect. After fermentation, mixed with selenite and post-processed, the obtained product had a significant effect on resisting harmful fungus and improving disease resistance of the plant.
