Abstract
Tomato (Solanum lycopersicum L.) production in countries like Mexico relies heavily on the use of chemical pesticides, which can be toxic to a host of other organisms including beneficial insects and human consumers. Environment-friendly methods of controlling tomato diseases include agroecological practices, organic fungicides, and biological control. Plants’ resistance against pathogens is induced by applying agents called elicitors to the plants and would lead to disease prevention or reduced severity. The objective of this research was to know the effect of three elicitor; namely, Activane (1.8 g L-1), Micobiol (3 mL L-1) and Stemicol (2.5 g L-1) plus a control on the incidence of diseases, vigor, yield and fruit quality of two cultivars of Bola tomato and Saladette in the greenhouse. Elicitors decreased the incidence and severity of presented diseases and increased plant survival. Additionally, the elicitors Micobiol® and Activane® were able to increase plant height, stem diameter, weight and fruit diameter, while Stemicol® considerably increased fruit color, °Brix and pH and Activane® increased titratable acid. In general, elicitors were able to reduce disease, increase plant survival, production and improve fruit quality. These findings provide positive directions for the possible use of these elicitors and induce resistance in plant protection.

Abstract
Determination of the optimum product components that would provide all actors is essential for agricultural products. Examining the most desired product characteristics for potatoes within the domestic market to contribute welfare and sustainability of a market-oriented agricultural production is of great importance for producers, intermediaries, and the community. In the present study, 3072 cross-sectional data acquired from consumers via face-to-face survey was used to determine optimum potato characteristics utilizing a multivariate Conjoint Analysis. It was found that potato has been consumed in fresh form in the domestic market. The factors affecting purchasing decision appeared to be 22.20% price, 20.22% sales point, 15.07% crust type, 22.13% crust color, and 13.23% view and package. The optimum product component scenario with a maximum utility value of 2.990 for the consumer at the community level was composed of the sales channels: local street market, price level: low (suitable), crust type: thin, crust color: yellow, view and product supply: 3 kg net, and scaling, and service: necessary. With the optimum product component set developed in the study, a market-oriented production model was determined for potatoes. Directing production within the determined scenario was considered a new way to assure sustainability of consumer and producer satisfaction and to solve market-related problems.
