Streptomyces padanus IA70-5 has been shown to be a promising biological control agent for the suppression of pepper anthracnose. In this study, we assessed the potential use of strain IA70-5 as a biological control agent for Phytophthora blight caused by Phytophthora capsici. Strain S. padanus IA70-5 was found to inhibit the mycelial growth and zoosporangium formation of P. capsici causing Phytophthora blight on pepper plants. In experiments with hot pepper fruit, IA70-5 suppressed the progression of Phytophthora rot by over 90% in pre-inoculated treatments with culture suspension. In experiments with 60-day-old pepper plants, IA70-5 suppressed Phytophthora blight by over 90%. These results demonstrated the potential for S. padanus IA70-5 to provide a practical biological agent for the control of Phytophthora blight in the field.

The study aims to assess factors affecting intention to purchase green products in Vietnam. The study employs samples from customers who have actually experienced green consumption in Vietnam. The samples were collected by convenient sampling methods. The survey obtained 206 responses with full information. The survey was conducted from October 2019 to January 2020. The measurement scale was a 5-point scale with 1- completely disagree and 5- strongly agree. This study employs factor analysis and structural equation modelling analysis. The results showed that the social and environment sustainability awareness have positive effects on altruism of customers who are interested in green consumption. Altruism also has the same direction on green purchase intention. Besides, the attitude toward buying green and health consciousness affects green purchase intention. At the same time, the altruism and attitude towards buying green products also influence positively on green purchase intention. Besides, the health consciousness positively affects attitude towards buying green products. The results show that the health consciousness has a negative impact on intention to purchase green products. The findings suggest that it is necessary to raise customers' health consciousness, customers' altruism from disseminating knowledge about environmental protection as well as society to enhance the green consumption in Vietnam.
