Implementation of Eco-friendly Technologies to Control Bacterial Leaf Blight of Rice Disease (Xanthomonas oryzae pv. oryzae)

Bacterial Leaf Blight (BLB) of rice (Xanthomonas oryzae pv. oryzae) is one of the major diseases of rice which can cause 10-95% yield losses. One of the environmentally friendly control efforts is the implementation of a rice cultivation technology package using the Paenibacillus polymyxa as biological agens. The purpose of this study was to determine the effectiveness of the technology package with the use of Paenibacillus polymyxa for controlling BLB disease and increasing production also profit analysis of farming. The research was conducted on 4 ha of rainfed rice fields in Malingping District, Lebak Regency, Banten Province, Indonesia. The environmental design used Nested Block Design with the three treatments:, an environmentally friendly control technology package (Paenibacillus polymyxa), a chemical control technology package (active ingredient methyl thiofanate), and farmers’ existing technology (pesticide mixture). Each treatment consisted of 2 varieties, Ciherang and Inpari 33, with 6 replications. The results showed that the application of environmentally friendly technology packages in the Ciherang variety was able to reduce the intensity of damage by 40.91% greater than the application of pesticides by farmers with an increase in production of 8.31-12.00%. The difference in the profits of farming was 10.52-22.85%.
