Influence of Temik (aldicarb) on herbicide persistence in cultivated cotton field soil under field conditions.

The effect of the insecticide Temik on the persistence of the herbicides Cotoran and Cobex was investigated in cultivated cotton fields. Temik was applied to the soil which had also been treated with Cotoran or Cobex. Residues were determined at 15 day intervals for four months. Temik was found to inhibit the degradation of both compounds as long as it persisted. As Temik disappeared the degradtation of Cotoran and Cobex increased, attaining after the 15th day the rates shown by Cotoran and Cobex when applied in isolation.
