Is the replanted rice damaged by quinclorac?
Q: 4 mu of direct seeding rice is in 3 leaves and 1 heart stage, few seedlings emerge after sowing, no seedlings are found in low-lying areas, the emergence rate is less than 50%, 7~7.5 kg are sown per mu, and not long ago, quinclorac "two kill" weeding is used. May I ask, if rice is replanted in this field where there is no seedling, will the replanted rice be damaged by quinclorac? A: Quinclorac is a selective herbicide for controlling barnyardgrass in rice fields. It is generally applied at the 2-leaf and 1-core stage of rice. It is easy to cause phytotoxicity when applied too early. Before seedling 1-leaf stage, especially seedling needle stage, apply two kinds of fertilizer according to conventional dosage.
