At the end of the study, tepraloxydim at high dose of 2x10 -3 M prevented Rhizoctonia solani colony growth at the highest level with the rate of (88.93%). Tepraloxydim at 5x10 -5 M inhibited R. solani colony growth at the lowest level with the rate of (0.21%). However, the growth rate of Phoma destructiva could not be decreased at this low dose level, but increased the growth of colony by (1.29%). As a result of study, the colony development of R. solani in in vitro conditions was completely inhibited at high dose application (2x10 -3 M) of fluazifop-p-butyl . At low dose (5x10 -5 M) application of herbicide, the colony development of P. destructiva was decreased by (4.68%) at the lowest dose level, but increased colony development of Rhizopus stolonifer by (4.14%). Metribuzin prevented colony development of Rh. stolonifer at the highest dose level of 2x10 -3 M by (63.47%) and the highest dose of application in in vitro conditions, It also prevented the development of Cladosporium fulvum at the lowest level (2.51%) when applied at 5x10 -5 M. Tepraloxydim at above and below (50%) affected sporulation of fungal pathogens with Alternaria alternata most affected (1.2x10 2 spore/ml; 2.7x10 2 spore/ml) under greenhouse conditions. High dose (above concentrations of 50%) application of fluazifop-p-butyl mostly affected Stemphylium solani ( 1.6x10 2 spore/ml ) in greenhouse conditions . A. alternata ( 3.0x10 2 spore/ml ) was the mostly influenced pathogen for fungal sporulation at low dose (below 50%) application of fluazifop-p-butyl herbicide . High dose application of metribuzin mostly affected Fusarium solani and Rh. stolonifer in greenhouse. The total number of spores determined at the last count for F . solani and Rh . stolonifer was (2.5x10 2 ) spore/ml. The number of A. alternata spores at low dose application was (4.1x10 2 ) spore/ml.
