Will rice suffer from quinclorac phytotoxicity after reseeding
Question: 4 mu of direct-seeded rice is at the 3-leaf 1-heart stage. Very few seedlings emerged after sowing, there are no seedlings in the low-lying areas, and the emergence rate is less than 50%. The sowing rate was 7-7.5 kg per mu. Not long ago, quinclorac was used for the "second kill" weed control. May I ask, if rice is reseeded in the areas of this field where no seedlings emerged, will the reseeded rice suffer from quinclorac phytotoxicity? Answer: Quinclorac is a selective herbicide for controlling barnyardgrass in paddy fields. It is generally applied at the 2-leaf 1-heart stage of rice, and applying it too early easily causes phytotoxicity. Before the 1-leaf stage of the seedlings, especially at the needle standing stage, applying quinclorac at the conventional rate

How to prevent and control rice diseases? Kejie Town in Changning County strengthens unified prevention and control
In June, continuous rainfall in Kejie Town, Changning County, caused bacterial leaf streak to occur to varying degrees in more than 8,000 mu of high-quality rice across the town. The town quickly organized agricultural science personnel, taking villages as units and focusing on high-quality rice demonstration plots, assigning two technicians from each village to go deep into farming households to provide scientific and technological guidance, fully launching a wave of unified prevention and control of rice, mainly targeting bacterial leaf streak. At the same time, a 200-mu high-quality rice demonstration area was established in the two villages of Kejie and Dadi, with 20 yuan per mu in unified prevention and control subsidy funds, and electric sprayers were used uniformly for prevention and control. As of
