Emulsifiable concentrates of indoxacarb

A formulation comprising:

• (a) one to twenty weight-percent of indoxacarb;
• (b) ten to thirty weight-percent of a primary emulsifier mixture comprising a combination of components (i), (ii) and (iii):
• (i) one to 15 weight-percent of a polyalkylene glycol selected from those having the following structure:
• R1O—(CH2CH(CH3)—O)x—(CH2CH2O)y—H
• where R1 is a branched or linear alkyl having 4-16 carbons;
• x is a number in a range of 0-11 and y is a number in a range of 1-20;
• (ii) five to fifteen weight-percent of an ethylene oxide/propylene oxide block copolymer that is hydroxyl terminated on both ends and that is characterized by having a molecular weight in a range of 2000 to 8000 and an ethylene oxide moiety weight that is 40-60 weight-percent of the total copolymer weight;
• (iii) one to ten weight-percent of sodium bisulfate adduct of bis(2-ethylhexyl) maleate;
• (c) one to fifteen weight-percent of a non-aromatic methyl ester co-emulsifier;
• and
• (d) ten to seventy weight-percent of solvent consisting of cyclohexanone and one or more than one additional non-aromatic solvent;
• where weight-percent is relative to total formulation weight unless otherwise stated and wherein the composition is free of aromatic solvents, amides, silicone containing components and azone.
