Kinetic equation of light degradation of insecticides. Note: Contents of SP + EM determined by HPLC.
| Insecticide | Formulation | Kinetic equation | Correlation coefficient | Half-life (d) |
|---|---|---|---|---|
| SP | Non-encapsulated | Qt = 13.5e−0.088t | 0.99 | 7.92 |
| In SP-EM-microspheres | Qt = 13.5 e−0.036t | 0.99 | 19.9 | |
| EM | Non-encapsulated | Qt = 3.36 e−0.096t | 0.99 | 7.26 |
| In SP-EM-microspheres | Qt = 3.37 e−0.046t | 0.98 | 16.2 |
