Taking into consideration the priority of providing healthy food for all society and eliminating all forms of nutritional deprivation mentioned in the Islamic Republic of Iran's Vision Policy of 1404 which declares the government's political commitment and overall determination in national-level policies to reduce hunger and malnutrition and achieve sustainable food security, the aim of the present study was to design a model for commercialization of organic products in Kermanshah Province. The present study used qualitative research methodology and with data foundation theory approach. The statistical population of the research included active professors in the field of organic products in the Faculty of Agriculture of Razi University, as well as city stores of organic products and experts of organizations related to the research topic. Targeted sampling was used first and then the snowball method. The number of participants in the study using the theoretical saturation index reached 19 people. Data was collected through in-depth interviews, direct observation, and library and online document study. The results of the research showed 27 main categories drawn paradigmatically. At the core of the paradigm model was the production and commercialization of organic products. Based on the findings in research of equipped laboratories, research and development of organic products in scientific centers, consumer disposable income level, marketing mix design, support rules and regulations, the need for a single organ in the field of organic products and alternative production process strategies were the most important factors influencing the commercialization strategies of clean (organic) products in the agricultural sector of Kermanshah Province.

In order to evaluate the effects of surfactants on the herbicidal properties of different acetic acid to citric acid ratios, a two-factor factorial greenhouse experiment was conducted with a completely randomized design with three replications. The first factor had twelve levels including acetic acid to citric acid ratios of 100:0, 80:20, 60:40 and 50:50 at concentrations of 2, 5, 10% of the said ratios as foliar application. The second factor involved the use of surfactants CDEA, LAE, SLS, KECO and control (no-surfactant) together with acetic acid-citric acid mixture. The results showed that at higher acetic acid to citric acid ratios, dry weight and leaf area of wild oat and wild mustard significantly decreased while their mortality rates increased considerably. When used in combination with acetic acid-citric acid mixture, surfactant tend to enhance herbicidal properties more than two times, particularly at concentrations of 5 and 10%.  According to the results, acetic acid to citric acid ratios of 100:0 and 80:20 at concentrations of 5 and 10% when used with CDEA or LAE provided the highest efficacy for non-selective weed control.
