摘要 |
The present disclosure relates to a pesticidal formulation including i) at least one pesticide, typically an organophosphate compound in an amount between 5.0% w/w and 40.0% w/w, preferably between 15.0% w/w and 30.0% w/w, ii) Solvent system comprising at least one glycol ether and at least one lactone in an amount between 10.0% to 80.0% w/w, preferably between 30.0% w/w and 55% w/w, with ratio of the glycol ether and the lactone is the in the range of 1:9 and 9:1, preferably in the range of 2:8 and 4:6, iii) Surfactant system containing at least two nonionic surfactants where the primary surfactant has an HLB range of 10 to 20 and the co-surfactant has a HLB range 1 to 5, in an amount ranging between 0.1% w/w to 60.0% w/w preferably in the range of 20.0% w/w to 40.0% w/w, and iv) at least one excipient in the range of 0.1% w/w to 10% w/w and preferably 0.5% w/w to 5.0% w/w. |

1. A pesticidal formulation comprising:
i. At least one pesticide, typically an organophosphate compound in an amount between 5.0% w/w and 40.0% w/w, preferably between 15.0% w/w and 30.0% w/w, ii. Solvent system comprising at least one glycol ether and at least one lactone in an amount between 10.0% to 80.0% w/w, preferably between 30.0% w/w and 55% w/w, with ratio of the glycol ether and the lactone is the in the range of 1:9 and 9:1, preferably in the range of 2:8 and 4:6, iii. Surfactant system containing at least two nonionic surfactants where the primary surfactant has an HLB range of 10 to 20 and the co-surfactant has a HLB range 1 to 5, in an amount ranging between 0.1% w/w to 60.0% w/w preferably in the range of 20.0% w/w to 40.0% w/w, and iv.
