Claims11
A method for preparing insecticidal pellets comprising i) a compound or mixture of compounds of the formula:
- ##STR3## where R and R.sup.1 individually are alkyl, alkenyl or alkynyl of up to 6 carbon atoms, R.sup.3 is hydrogen or alkyl of 1-6 carbon toms, R.sup.2 is hydrogen, alkyl of 1-18 carbon atoms, cycloalkyl of 3-8 carbon atoms, alkenyl of 2-18 carbon atoms or alkynyl of 3-18 carbon atoms, and Y is oxygen or sulfur;
- ii) a second active ingredient selected from the group consisting of fungicides, herbicides, fertilizers and other insecticides;
- comprising the steps of
- (a) forming an extrudable mixture comprising said compound and said second active ingredient;
- (b) forming said pellets by extrusion of said mixture extrudable and cutting the extrudate.

A method for preparing solid insecticidal pellets comprising (i) a compound or mixture of compounds of the formula:
- ##STR4## where R and R1 individually are alkyl, alkenyl or alkynyl of up to 6 carbon atoms, R3 is hydrogen or alkyl of 1-6 carbon atoms, R2 is hydrogen, alkyl of 1-18 carbon toms, cycloalkyl of 3-8 carbon atoms, alkenyl of 2-18 carbon atoms or alkynyl of 3-18 carbon atoms and Y is oxygen or sulfur;
- and (ii) a second active ingredient selected from the group consisting of fungicides, herbicides, fertilizers and other insecticides;
- comprising the steps of:
- (a) forming a suspension or solution containing said compound and a dispersant, wetting agent and/or surfactant;
- (b) evaporating the solvent from said solution or dispersion;
- (c) dividing the remaining solids into particles;
- and
- (d) mixing said particles with said second active ingredient and forming the resultant mixture into pellets.
