Abstract

Blast disease is one of the most devastated plant pathogens that can cause yield loss in rice. Blast disease is caused by the fungus Pyricularia oryzae (teleomorph: Magnaporthe oryzae). This study aims to determine the cultivation techniques practiced by farmers and their relationship with the severity of blast disease in rice plants. The study was conducted using two methods, namely structured interviews with 60 respondents and direct observation of blast disease severity in the field.Obtained data was then processed using Microsoft excel 2019 and the χ2 (Chi-square) test was conducted to see the relationship between the Cultivation and Environmental Factors that Affect the Rate of Blast Disease at the α = 5% level. The highest average disease severity occurred in Babakan Pari village with a severity of 24.95% and the lowest severity in Pondok Kaso Tengah village 13.03%. Sufficient of P and K fertilization, no water stress, the use of certified seeds, and full return of straw tended to reduce blast disease severity. Meanwhile, the use of herbicides in weed management shows a higher level of disease severity compared to only mechanical methods.
