摘要： Calcium carbonate has been widely applied in biomedical fields, but its potential as an agricultural pesticide carrier, particularly its capacity to modulate plant metabolism following pesticide loading, remains insufficiently investigated. In this work, calcium carbonate microspheres with a size of 1–2 μm were synthesized via a simple co-precipitation method. The microspheres had a hollow, spherical structure made of self-assembled nanoparticles sized at 43 nm, with a sustained-release period of 27 days for the management of wheat crown rot. A metabolomic approach was used to investigate their different impacts on wheat seedlings. It was shown that the fludioxonil microspheres could promoting wheat growth by regulating multiple metabolic pathways, including amino acid metabolism, carbohydrate metabolism and some secondary metabolism, which reduced the negative effects of fludioxonil on wheat growth. This study represents the first investigation into the effects of calcium carbonate-pesticide microspheres on plant growth, providing novel and significant insights.
