Soil Algae: Soil algae (both prokaryotes and eukaryotes) luxuriantly grow where adequate amount of moisture and light are present. “The soil Root Interface”. Root growth seemed to be more affected by high IAA producers in unsterile soil and maximum vigour index of 32600 was exhibited by BA2(D)1 which is a medium IAA producer and the minimum of 15750 was by BA1(E)2 which is a high IAA producer. Here belong the majority of Lumbricidae, the Mollusca, the large-sized chilopods, arachnids and insects and the soil-dwelling or fossorial vertebrates.

The results in some way do establish that plant growth is not directly influenced by high IAA producers. Burhanan, R.E. ciceri. Fungal Decomposition of Wood: Its Biology and Ecology. When the shoot lengths were compared, highest shoot length of 213.3mm (sterile soil) was by BA4(D) which is a medium to high IAA producer and in unsterile soil highest shoot length of 198.67mm was shown by the isolate ND1which is also a medium to high IAA producer.

INTRODUCTION The problem of environmental contamination by pesticides goes beyond the locality where it is used. Microbes that harm plants are plant pathogens since the harm that they cause is considered disease.

There were significant differences in the amounts of IAA produced by the isolates and more amounts of IAA were released in trypt+. And various biochemical tests were done.
