| Abstract | ||
| 19 Trichoderma isolates were identified distributed on four species , 12 isolates related to T. harzianum ,3 isolates related to T. viride , 3 isolates related to T.atroviride and one isolatet related to T. longbrachitum the research was study effect of Trichoderma spp isolates on various Mushroom Agaricus bisoporus production stages.in which the effect of Trichodera The results showed that afist stage (spawning) was the most affected in Trichoderma isolates . T6 ( T.harzianum) isolate (were isolated from agriculture yield in Tikrit university )showed maximum inhibition of A. bisporus mycelium in spawning stage in which the infection percentage was (73%) while the minimum infection was 19.23% by T19 . The results showed that a first stage was more affected in A. bisporus yield by Trichoderma isolates percentage infection 71.60 % and was manimum yield was 159.81 g ( biological efficiency 6.68% by treatment with T6 isolate, compared to 2304 .2 g/ 8 kg compost ( B.E )( 96.10%) in control without any infection ). while minimum effect by T19 isolate (percentage infection 5.3)with 1031.44 g /kg compost yield (B.E 45.8) was recorded. The 3th (last A. bisporus production stage (maturated fruit bodies) showed the least response with Trichoderma sp infection compared to 1st stage , the maximum infection was 8.26% with 1288.06 g/8kg compost yield (B.E 53.77%) byT6 compared to minimum percentage infection 0.43% and (1936.30g/8kg compost) (B.E79.4%)by T19 yield compared. | ||
