| Abstract/Contents: | A study was undertaken to evaluate thatch control by 3 insecticides in turfgrass. Insecticide location in the soil and thatch was also studied. "Dieldrin and chlordane applied three times a year over a five year period resulted in a build-up of thatch on the soil surface in bluegrass turf. One inch of thatch was present in all replicates of chlordane and dieldrin. No build-up occurred in plots treated with carbaryl (Sevin) three times yearly for the past five years. Untreated plots exhibited no thatch accumulation." In follow-up tests on the now-divided plots, insecticide levels were highest in the top 1" of soil where thatch was removed and treatments continued. There was very little difference in residue amounts in the layer 4-5" deep . Thatch continued to contain high amounts of insecticide even where treatments had ceased for 14 months. |
