T/ZNX 002-2022 30% Spinosad and Imidacloprid Suspension concentrate

Scope

Main technical contents: **Project Indicators**: - Esfenvalerate mass fraction (%) 14.1–15.9 - Thiamethoxam mass fraction (%) 14.1–15.9 - pH value 5.0–8.0 - Esfenvalerate suspension rate (%) ≥95 - Thiamethoxam suspension rate (%) ≥95 - Pourability Residue after pouring (%) ≤5.0 Residue after washing (%) ≤0.5 - Wet sieve test (passing through a 75μm sieve) (%) ≥98 - Persistent foaming (foam volume after 1 minute) (mL) ≤40 - Low-temperature stability After cold storage, the suspension rate and wet sieve test still meet the requirements of this document. After heat storage, the mass fractions of esfenvalerate and thiamethoxam should not be lower than 95% of the pre-storage values, and the pH value, suspension rate, pourability, and wet sieve test should still meet the requirements of this document. --- **Explanation of technical terms**: 1. **Esfenvalerate**: A broad-spectrum insecticide used in agriculture. 2. **Thiamethoxam**: A neonicotinoid insecticide with systemic activity. 3. **pH value**: A measure of the acidity or alkalinity of a solution. 4. **Suspension rate**: The percentage of a substance that remains in suspension after mixing with water. 5. **Pourability**: The ability of a substance to flow freely when poured. 6. **Wet sieve test**: A test used to determine the particle size distribution of a material. 7. **Foaming stability**: The ability of a substance to maintain a stable foam after exposure to certain conditions. 8. **Low-temperature stability**: The ability of a substance to maintain its physical and chemical properties at low temperatures. 9. **Heat storage stability**: The ability of a substance to maintain its properties after being stored at elevated temperatures. --- **Translation notes**: - Technical terms are translated according to their standard English equivalents. - Numbers and units are preserved in their original format (e.g., “14.1–15.
