They begin to damage the seedlings when the seedlings emerge 5 cm above ground. Control methods: (1) Mix 1 part of 3% zinc phosphide with 95 parts of green vegetables, beans, rice, etc.; after mixing well, scatter the bait in the evening in places where rats frequently appear or at their burrows. (2) Mix 1 part of 0.5% bromadiolone evenly with 3 parts of flour, then add cut apple pieces, vegetables, and fried dough sticks (cut into 1 cm pieces) and mix them evenly to coat; this can be placed in the evening in places where rats are frequently active. Alternatively, use 2.5% phorate granules at 1500 g per 667 sq m mixed with 10 kg of fine soil and scatter it along the edges of beds and ridges to drive rats away; be careful not to scatter it on the seedlings.
