A: The “lantern grass†mentioned in the text message should be yarrow grass. If it is communis communis, combined with control of valerian, the use of penoxsulam has better control effect on the grass; when the grass age is relatively large, fluoxypyr, valerifolazine, flufenoxaone and It is controlled with a mixture of 2 A and 4 chlorine. Note that 2 A 4 Cl can only be used after the 4-leaf stage of rice.
Tip: Machine inserting rice is generally transplanted at the heart stage of seedlings at the 3 leaves and 1 leaf stage. If the seedlings are in the 3-leaf stage, they should be in the paddy field and should not use 2A 4 chlorine.
