The application provides a high-purity thermostable crystal form of a substituted 3-isoxazolidinone compound, a preparation method therefor and an application thereof. The High-purity thermostable crystal form is prepared by a particular method of the present technology and is determined by single-crystal X-ray diffraction as an orthorhombic crystal, featuring a space group of P212121 and lattice parameters of a=9.2301(2) Å, b=11.0751(3) Å, c=12.7554(3) A, α=90°, β=90°, and γ=90°. The orthorhombic crystal can be conveniently applied in preparation of agrochemical formulations, such as a suspension concentrate and a water dispersible granule, and the new formulations prepared have a better herbicidal activity and crop safety.
