AB  - Two insecticides were applied separately to the soil at 4000 and 8000 ppm for thiodan&reg; and 6000 and 12000 ppm for karate&reg;, respectively. Their effects were investigated at 0, 14, 21, 28, 35, 42 and 49 Days after Treatment (DAT) on the population of bacteria, fungi, actinomycetes and protozoa in the soil.  The microbial population was estimated using the standard dilution plate technique.  The two insecticides investigated at both rates of application significantly (p 0.05) reduced the fungi, actinomycetes and protozoa population in the  soil.  Whereas  the  bacteria  population  was  significantly  (p 0.05)  increased.   Thiodan  at  the  rate  of 8000 ppm gave significantly (p 0.05) lowest population of fungi in the soil compared to actinomycetes and protozoa population.  A progressive increase in the soil microbial population for various insecticidal treatments in the order of 49DAT > 35DAT >28DAT > 21DAT > 14DAT > 0DAT was observed.  The significance of thiodan  and  karate  insecticide  at  two  different  rates  of  application  on  the  soil  microbial  population  is herein discussed.
