This study was reported to assessment the impact of bio-control fungi[ Trichoderma harzianum . Rafai( T. h. t ) and Chaetomium elatum ( C. e )] isolates in controling Echinochloa grus . Gali weeds which growing with the rice- class Yassamine cultivation. The first laboratorial experements were consisted isolation, purification of fungi in rice fields (AL-Mishkhab at agricultural season 2018), and comparing their pathogenicity, promotional abilities through putting a rice and Echinochloa seeds with studied bio-control fungi (their biomass and filterates), as well as the second experiments were acheived by using petri dishes which treated with studied fungi and their filtrates, in order compare the seeds germination rate, plumiles lengths (cm), plumiles fresh and dry weights (gm) of rice and Echinochloa seedlings, these experiments was designed with Completely Randomized Design(C. R. D) The results were as follow; 1-Treatments with the biological control fungi, T. h. t and C. e caused 95. 23, 94. 21, 91. 29 % germination rate of rice seedlings. 2- The T. h. t. fungi and its filtrates gave an significant results in controlling of Echinochloa weeds which were cultivated in petri dishes, Echinochloa germination rates in petri dishes reached 7. 11 % and its filterates gave 11. 49% in petri dishes. Also T. h. t. and their filtrates were appeared a significant results in combating Echinochloa germination rates by decreasing plumiles lengths, plumiles fresh and dry weight that reach 1. 84, 0. 68 % and 0. 077, 0. 019 cm and 0. 019, 0. 009 cm, respectively in compare with control treatment which were 4. 70, 1. 29% and 0. 209, 0. 031cm and 0. 038, 0. 024 cm, respectively.
