Seedling field borer, the effect is reflected in the killing of the flyworm at the time, such reports are many. And seedling field borer on Honda Cessation and ending the relationship between the yield of how? Author from 1979-1984 with formal field trials and large areas on the field of observation and verification methods to deal with several aspects of rice seedling stem borer are explored, and now The results reported as follows: First, the seedling field management borer has nothing to do with the Honda withered seedling seedling seedlings in 1979 a lot of the rate of 52% of the dry sheath, 35%, 25%, 15%, 5%, 0% Seedlings, planted 200 piles per district, get the corresponding dry heart rates were 0.43%, 1.31%, 3.64%, 3.05%, 7.12%, 1.00%.
