| Abstract: | Gratiola japonicn Miq is a kind of new raised weed in rice field. The booming period of emerging seedlings is at mid-June. At branch period between the last ten days of June to the first ten days of July, it blooms for white flowers and bears fruits. There are 250-350 seeds each capsule and 20-30 capsules each plant follow down naturally when they were ripe. It make rice decline yield about 25%, so use 48% Bentazone and Agritox to prevent and cure. |
