Use of polyglycerol esters as carriers for microbiological active ingredients

A composition, comprising:

• at least one active microbiological ingredient, and
• a carrier, comprising at least one polyglycerol ester, for the at least one active microbiological ingredient;
• wherein a proportion by mass of the carrier based on a total mass of the composition is 40% to 99%;
• wherein a proportion by mass of the at least one polyglycerol ester based on the total mass of the carrier is 60% to 100%, and
• wherein the at least one active microbiological ingredient is selected from the group consisting of Bacillus Subtilis, Trichoderma harzianum, Bacillus amyloliquefaciens, Beauveria bassiana, Metarhizium rileyi, Metarhizium anisopliae, Clonostachys rosea, Aureobasidium pullulans, Coniothyrium minitans, and their organs,
• and
• wherein the carrier optionally comprises at least one emulsifier,
• wherein the at least one emulsifier is selected from the group consisting of a sorbitan fatty acid ester and an ethoxylated sorbitan fatty acid ester, and
• wherein the at least one polyglycerol ester comprises triglycerol trioleate.
