| Fenvalerate, first developed by Sumitomo in 1973 and introduced commercially in 1976 as an emulsifiable concentrate, is one of the potent pyrethroid insecticides widely used to control broad-spectrum insect pests. |
| Do not add emulsifiable liquids to the mixture unless previous use of the materials being combined has proved them compatible. |
| Emulsifiable concentrates can be used in houses with painted walls, where deposits left by wettable powders may be deemed objectionable. |
| Crude oils, irrespective of their origin, contain certain components or characteristics which tend to make them emulsifiable. |
| Granular, flowable, and wettable powders are less susceptible to volatilization than emulsifiable concentrates and soluble powders. |
| Wettable powders, soluble powders and emulsifiable concentrates all can be mixed with water, but the percentage of the pesticide varies greatly. |
