Once a rice plant is infected by tungro, it cannot be cured.
Preventive measures are more effective for the control of tungro than
direct disease control measures. Using insecticides to control
leafhoppers is often not effective, because green leafhoppers
continuously move to surrounding fields and spread tungro rapidly in
very short feeding times.
The most practical measures at present, include
Grow tungro or leafhopper resistant varieties.This is the most
economical means of managing the disease. There are tungro-resistant
varieties. Contact your local agriculture office for up-to-date lists of varieties available.
Practice synchronous planting with surrounding farms.Delayed or
late planting, relative to the average date in a given area, makes the
field susceptible for Tungro. Late-planted fields also pose a risk to
early planting in the next season.
Adjust planting times to when green leafhopper are not in season or abundant, if known
Plow infected stubbles immediately after harvest to reduce inoculum
sources and destroy the eggs and breeding sites of green leaf hopper.
