Project indicators Picoxystrobin mass fraction/% 6.3~7.7 Propiconazole mass fraction/% 11.3~12.7 pH value 5.0~8.0 Picoxystrobin suspension rate/% ≥90 Propiconazole suspension rate/% ≥90 Wet screening test (Passing 75μm test sieve)/%≥98 Persistent foaming property (foam volume after 1 minute)/mL≤60 Pourability, residue after pouring/% ≤5.0 Pourability, residue after washing/% ≤0.5 Low temperature stabilitya After cold storage, the suspension rate and wet screening test should still comply with the requirements of this document. Thermal storage stability a. After thermal storage, the mass fraction of picoxystrobin and propiconazole should not be lower than 95% of that before thermal storage. The pH value , dumpability, suspension rate and wet sieving test should still comply with the requirements of this document. During normal production, low temperature stability and thermal storage stability tests should be measured at least once every 3 months.
