Increasing the Stability of the Antagonistic Fungus, Talaromyces Flavus using some Organic and Mineral Compound
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2018, Vol 8, Issue 1
Abstract
The important issues of interest to the biological fungicides production companies are marketing capabilities and commercialization of these compounds. According to the investigations made, increasing the efficiency and sustainability of such compounds, commercialization of important factors affecting the marketing capabilities and considered them. In this study, for increasing the stability of bioformulations related to different Talaromyces flavus isolates, the most effective stabilizers related to its metabolites (kitinase enzyme, glucose oxidase enzyme and ethilen compounds) were used. Based on previous research, the most effective platforms in terms of sporulation and stability depending on T. flavus isolates, rice bran for the isolates related to the potato fields (TF-Po-V-48), sugar beet fields (TF-Su-K-1) and cotton fields (TF-Co-G-1) and peat soil mixed with rice bran for the isolates related to cultivated areas related to tomato (TF-to-V-29 and TF-to-U-38) and greenhouse cucumber (TF-Cu-V-59) was introduced. So, this research was performed in two separate experiments, for substrates peat soil mixed with rice bran and rice bran corresponding to a completely randomized design in fifteen treatments and three replications. The treatments consisted of a combination of three different T. flavus isolates with each of the five used stabilizers including aminophenol, dicycloserine, carboxymethyl cellulose, magnesium sulfate and sodium nitrate. Based on the stability of T. flavus isolates, the treatments were evaluated as determining the percent of active ascospores. The evaluation time range, three weeks after treatment developing was started and every 90 days for 21 months continued. The results showed that for all treatments, the highest level of stability in the second quarter happened. In both experiments, peat soil mixed with rice bran and rice bran, dicycloserine, sodium nitrate and magnesium sulfate were very efficient in increasing the the stability of different T. flavus isolates, when compared to two other stabilizers (aminophenol and carboxymethyl cellulose). Among these stabilizers, sodium nitrate for the isolates related to sugar beet and dicycloserine for other isolates caused the maximum percentage of T. flavus active ascospores.
