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, application of quinclorac at conventional dosage was also easy to cause phytotoxicity. Quinclorac was applied to the above fields, and rice was easily damaged by the pesticide, but large seedlings could be transplanted from other places to the lack of seedlings.
