Pepper (Capsicum annum) is one of the valuable Solanecea plants, is widely growing either in greenhouses or in fields in Turkiye. We have been producing several varieties of pepper seeds for commercial production in our experimental greenhouses. Recently there have been bacterial and fungal diseases problems occurring and have been managing chemical applications. We found that excessive use of pesticides and chemical fertilizers on long-term large-scale pepper seed production of the single crop, has destroyed the greenhouses ecological environment allowing plant diseases. We aimed to re-store beneficial microorganisms using Bacillus spp and Trichoderma spp. Pepper plants were tested with randomized complete block design (RCBD), with 8 treatments and 2 replicates. For testing commercial Bacillius substilis, Bacillus amyloliquefaciens and Trichoderma harzianum preparates have applied as suggested (1×), half, 1.5 and double concentrations with only distilled water as control. During a month time, all tested plants were monitored every 7-day intervals with 0 to 3 disease scale. The time studies have revealed that all commercial biological preparats affected positively at suggested and higher concentrations against foliar diseases such as pepper bacterial spot diseases. Additionally, the applied antagonistic microorganisms have established induced systemic resistance (ISR) in pepper plants during a month period.
