Abstract
Gresik is one of the ten highest rice producing regions in East Java Province, Indonesia. Rice production in Babaksari Village, Dukun District, Gresik Regency reaches 646 tons/year. One of the constraints in rice production is the attack of bacterial leaf blight caused byXanthomonas oryzae pv. oryzae. This study aims to determine the effect of abiotic factors (air humidity, soil pH, and air temperature) on the development of bacterial leaf blight, and the control techniques carried out by farmers in Petissari Hamlet and Sariwonorejo Hamlet, Babaksari Village. The research was conducted on paddy fields located in Petissari and Sariwonorejo hamlets. The research was conducted by direct observation every 7 days using diagonal random sampling to obtain incidence, intensity, disease Infection rate, and observed abiotic factor values, as well as interviews to find out the control techniques used by farmers. Data were processed using IBM SPSS Statistics 25, with T test, multiple linear regression test, correlation test, and path analysis for quantitative data, while the frequency distribution technique for qualitative data. The results showed that the incidence, intensity, and infection rate of bacterial leaf blight in the two hamlets had significant differences with a significance value < (α = 0.05), and the intensity of the disease was higher in Sariwonorejo Hamlet by 15.709%. There are 2 regression models for the intensity of bacterial leaf blight in Babaksari Village, namely: (1) Petissari Hamlet: Y = -0.050 + 0.587X1 +1,378X2 - 0,789X3; and (2) Sariwonorejo Hamlet: Y = 8.464 - 3.044X1 +3,745X2 + 1,854X3. The abiotic factor that has the highest influence on the development of bacterial leaf blight in the two hamlets is variable X3 (soil pH). 86.7% of farmers in Petissari Hamlet controlled bacterial leaf blight by applying biological agents (20%) and bactericides (50%), while 73.3% of farmers in Sariwonorejo Hamlet controlled the disease by applying fungicides that were considered inappropriate target (43.3%)
