How to Prevent Rotten Seedlings Is an Important Problem of Early Rice Seedling Raising. Cause a lot of rotten rice seedling factors, on the whole, in addition to physical factors, the pathological factors can not be ignored. After emergence of seedling in 1980, our region encountered a history of rare long-term low temperature rainy weather, in order to reduce losses, we use the enemy Kesi and other pesticides spraying seedling field, to investigate its prevention and treatment of rotten seedlings, to improve the rate of seedlings. The spring of 1981 made further tests, the results of two years are summarized as follows:
