Bacterial Blight of Rice
Xanthomonas oryzae pv. oryzaebacteria
On the leaves of rice, light green to greyish-green water-soaked streaks appear. Later, these lesions merge and form larger yellowish-white lesions with uneven edges. In the final stage of infection with Bacterial Blight, rice leaves are covered with a white to grey fungal layer. The leaves starts to wilt and die. In the morning, you can observe milky dew drops of bacterial masses on young lesions - they dry up and leave a white encrustation.
The bacteria are spread by wind and rain splash or irrigation water. Favorable factors for the spread of the disease are high humidity, strong wind and temperatures of 25°C to 30°C. High nitrogen fertilization also favors the diseases.
Biological control of Bacterial Blight is relatively recent and not currently in common use.
To combat Bacterial Blight, apply Streptomycin sulphate and a Tetracycline combination 300g plus Copper Oxychloride 1.25 Kg/ha.
