| method_description | Observe the damages on plants caused by rice delphacid. For a field test, use an augmented experimental design with a susceptible check replicated at intervals across the whole trial. The test is considered a valid test for resistance if the hopper population is uniformly distributed at a high level across the screening box, as indicated by hopper counts on the susceptible check. A minimum of the following hopper density on susceptible check is necessary: a. 10 hoppers/hill at 10-15 days after transplanting, b. 25 hoppers / hiII at maximum tillering, c. 100 hoppers/hill at early booting stage |
