Fosthiazate pesticide formulations
A method of making a formulation may include a step of forming a mixture comprising: a hydrotrope, a surfactant, a water-immiscible solvent, an isocyanate monomer, a salt, fosthiazate and water. Further, a step of adding an amine to the mixture to polymerizing the isocyanate monomer may be performed.
1. A method of making a formulation, comprising the steps of:
forming a mixture comprising:
a hydrotrope selected from one or more from the group consisting of dipotassium 2-(3-methylphenoxy)ethyl phosphate, sodium cumene sulfonate, and sodium xylene sulfonate and present at 2.5 wt % to 7.5 wt %;
a surfactant;
a water-immiscible solvent;
an isocyanate monomer;
a salt comprising a sulfate anion and present at 0.03 mol % to 0.08 mol % of the formulation;
fosthiazate; and
water; and
adding an amine to the mixture to polymerizing the isocyanate monomer.
2. The method of claim 1 , wherein the fosthiazate is from 20 wt % to 35 wt % based on a total weight of the formulation.
3. The method of claim 1 , wherein the water-immiscible solvent is from 10 wt % to 30 wt % based on a total weight of the formulation.
4. The method of claim 1 , wherein the surfactant is from 0.5 wt % to 2.5 wt % based on a total weight of the formulation.
5. A formulation, comprising:
2.5 wt % to 7.5 wt % hydrotrope selected from one or more from the group consisting of dipotassium 2-(3-methylphenoxy)ethyl phosphate, sodium cumene sulfonate, and sodium xylene sulfonate based on a total weight of the formulation;
20 wt % to 35 wt % fosthiazate based on a total weight of the formulation;
10 wt % to 30 wt % water-immiscible solvent based on the total weight of the formulation;
0.5 wt % to 2.5 wt % surfactant based on the total weight of the formulation;
0.03 mol % to 1.6 mol % salt comprising a sulfate anion;
water; and
the reaction product of an isocyanate monomer and an amine.
