Survivability and Benefit Evaluation of Streptomyces sp. and Trichoderma sp. as Active Ingredients of Biopesticides and Soil Fertility Enhancer in Shallot Fields at Wates Village Tulungagung

Abstract

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.
