ABSTRACT:
The present invention relates to a novel aqueous flowable composition of fenazaquin. It was found that conventional aqueous flowable formulations resulted in a product that lost miticidal activity during storage. The low miticidal activity was found to be due to an unacceptable level of particle size growth during storage. It has been found that an aqueous flowable fenazaquin formulation of satisfactory particle size stability can be made when a higher than normal concentration of sodium naphthalene formaldehyde condensate dispersant is utilized in the formulation.
