The investigation was carried out under partially controlled glasshouse conditions, at the Agricultural Research Station, AL-Rabbah, Mu'tah University, in the growing season (2011).

To evaluate the potential use of organic manure (poultry and sheep).

0, 20 and 40 tons/ ha .and bio-control (Trichoderm harzianum) on vegetative growth, macro nutrients content and the response to root rot caused by (Phytophthora fragariae) of strawberry (Fragaria xananassa Duch) cultivars (albino).

The result showed that all application organic manure was increased vegetative growth and root .

When application of bi-control and manure increased the shoot growth with or without bio-control.

While the experiments showed that significant effect in root fresh weight with poultry manure When the pathogen was present the fresh root weight is increased with sheep manure.

The dry shoot weight increased when apply of the two type of organic manure and significantly effect when were added the bio -control and pathogen present or absent they will be increased of dry weight.

While thy dry root weight was increased with the manure types and levels compared with control.

The total leaf number significantly affected with manure type and levels and also the bio- control.

The total number of runners total was increased with increased of manure levels and bio -control.

When pathogen was present the number of runners increased with all treatments.

Nitrogen content was doubled and has significant effect with bio- control to all treatments when the pathogen was absent .Nitrogen content was decreased when the pathogen present with manures and bio-control was absent in both part of plants.

Application of organic manures and bio-control increased the phosphorus content in plant and increased with manures levels.

Application of bio -control to all treatments increased phosphorus in shoot part compared with that of the control.

Treatments with bio-control and with pathogen or not it was increased the potassium level in shoot .

in the other hand the potassium content was increased in root too.

When added bio -control and present of pathogen or not.

Furthermore, addition of Trichoderma increased vegetative growth parameters,shoot and root N , P , and K content in presence or absence of phytophthora.

Disease percentage and diseases severity was increased when we did not application any amount of organic manure its reached above 70% in case of not added manure and bio -control .
