Abstract/Contents:The purpose of the present field cage research was to test the efficacy of azadirachtin, 720-F, an experimental neem-derived product, in comparison with diazinon 5G for the control of the southern chinch bug Blissus insularis in St. Augustinegrass. Diazinon 5G, adopted as a standard in this test because of its wide usage, was highly effective against adults and all sizes of nymphs. No survivors of this treatment were recovered, and it was statistically superior to all other treatments. None of the azadirachtin 720-F treatments were significantly different from the untreated control. This argues that higher doses may be desirable. Higher levels of active ingredient could be achieved by applying the total dosage at one time or by increasing the dose for each date.
