Abstract:

In 2 field-cage tests, a slow release granular formulation consisting of 80% petroleum charcoal, 10% water-insoluble binder, and 10% aldicarb (designated PC-10) applied to the soil gave an additional 7–10 days of control of the boll weevil, Anthonomus grandis Boheman, compared with the standard corncob formulation applied in the same manner. A formu1ation with 20% water-insoluble binder (designated PC-20), and consequently a slower rate of toxicant release, gave similar results in 1 test, but in a 2nd test was no more effective than the corncob formulation.

In 2 of 3 field tests, counts of plant stand indicated that the PC-20 formulation was less damaging to cotton seedlings than the corncob formulation when both were applied as in-furrow treatments at planting. In 3 field tests, the PC-20 formulation appeared more effective against the boll weevil than the corncob formulation. Also, it was more effective against the cotton f1eahopper, Pseudatomoscelis seriatus (Reuter), in 2 of the tests.
