TESTING SEVERITY OF THE DISEASES CAUSED BY PATHOGEN

In the present study 10 fungi isolated from the groundnut rhizosphere and pure culture prepared, from these pure culture fungi, fungal filtrate prepared and treated with five groundnut varieties germination and growth of radicle against time 2 hours' time interval up to 10 hours.. In 2 hours treatment Out of ten, seven fungi showed non-significant difference means it did not affect the seed germination and growth of radicle, in four hour treatment The seeds were treated with Rhizopusstolonifer culture filtrate showed very less growth of radicle that is 0.07 cm. Tricodermaviride and Fusarium oxysporum treated seeds also showed a very little growth of the radicle i.e. 0.99 cm and 0.28 cm respectively. In four hours treatment Curvularialunata and Aspergillus fumigates showed significant difference, also non-significant difference observed in six hours treatment Penicelliumdigitatum and Fusarium oxysporum showed very less growth of radicle i.e. 0.41 cm and 0.97 cm respectively.in eight hours treatment of the fungal culture filtrate, treated seeds showed non significant growth. Fusarium oxysporum showed very less growth i.e. 0.51 cm. Aspergillus terrus, Tricodermaviride, Macro phominaphaseolina, Rhizopusstolonifer showed some equal values 2.51 cm, 2.61 cm, 2.71 cm and 2.61 cm respectively and control was of 3.20 cm. Penicelliumdigitatum, Aspergillus niger, Curvularialunata, Aspergillus fumigates showed an average length of radicle as 1.50 cm. After 10 hours treatment except Tricodermaviride all fungal culture treated seeds showed non significant difference
