Abstract:The results of field tests against the imported fire ant (Solen- Opsis saerissima v. riehteri Forel) with various application rates, formulations and split applications of granulated heptachlor showed that: (1) there was no appreciable difference in the immediate kill obtained with bulk granular applications at rates of 5 pounds of 20% heptachlor versus 20 pounds of 5%, and 10 pounds of 20% heptachlor versus ;20pounds of 10%; (2) formulations with caleined attapulgite granules gave slower initial kill than ones with regular granules but there was not an appreciable difference after 1 year: (3) formulations with a large mesh size granule (8 to 20) gave slightly slower initial kill than a fine mesh granule (30 to 60), but after 2 months there was no appreciable difference and at the end of 1 year they showed a slightly grater kill; (4) two applications of heptachlor at dosages of 1/4 or 1/2 pound per acre put out at intervals of 3 or 6 months were completely effective in controlling imported fire ants. Two applications of one-eighth pound per acre gave a very high degree of control.
