“…According to Nduka et al [12] Streptomyces and Trichoderma are beneficial soil microorganisms that act as decomposers of organic matter and Plant Growth-Promoters as well as biological agents. Specifically, Trichoderma can increase soil fertility by increasing the availability of macronutrients N, P, and K as well as other micronutrients through the process of decomposition of organic matter and nutrient fixation [6].…”

The purpose of research on the Farmer Empowerment Program in Wates Village is to increase knowledge in the field of sustainable agriculture and transfer of technology for the application of biopesticides containing the Biological Control Agent (APH) Streptomyces sp., Trichoderma sp. combined with shallot cultivation technology in the village of Wates Tulungagung. Innovative methods and Participatory Action Research (PAR) are used to encourage transformative action, by involving community members as PAR implementers in describing the types of plants being treated and applying them during the Covid-19 pandemic in the Wates village, Tulungagung District. The results of the evaluation and monitoring of the use of APH as a biopesticide and fungicide to control moler disease caused a decrease in the population of microorganisms, the population of Trichoderma sp. was absent (o) but Streptomyces sp. increase. Giving APH proved that microorganisms act as decomposers that increase the availability of N and P nutrients through their ability to accelerate the decomposition of organic matter given at the beginning of planting. The K nutrient content in the soil before and after treatment did not differ.

서 론 한국잔디(Korean lawngrass)의 갈색퍼짐병의 원인균은Rhizoctonia solani AG 2-2로 알려져 있다 (Green et al., 1993 S. lydicus WYEC108을 기본으로 하여 제조한 Mycostop은ABSTRACT. Large patch disease in Zoysia japonica Steud. is the most destructive disease in turfgrass. For large patch management, it has been dependent on chemical controls but pesticides are harmful to soil, water and biodiversity. In this study, we evaluated 4 Streptomyces spp. strains (S2, S5, S8 and S12) which were selected in previous studies using metagenome approaches. Root colonization of the strains, large patch suppressing effect and the pathogen density change in actual golf course were investigated to evaluate biological control potential of the strains. All strains exhibited reliable root colonization ability that strains populations were higher than 6 log cfu g −1 in turfgrass rhizosphere. The pathogen density, with S8 treatment, was detected average of 0.7 after a week and average of 1.2 after 4 weeks. Disease control and suppressive the pathogen population by S8 strain showed higher efficiency than other strains. S8 was applied in an actual golf course for the large patch control and pathogen density. The pathogen density in S8 treatment plot was detected below 1.6 per toothpick and lower compared with untreated plot. The results indicated that pathogen density was suppressed by S8 and the stain has great potential as a biological control agent for the large patch.
