摘要

The objectives of this research were to evaluate herbicide safeners and water repellents for their efficacy in reducing injury caused by isoxaflutole to corn at four application timings (PRE, spike, two-leaf, and four-leaf), and to evaluate the retention of the combinations of isoxaflutole, herbicide safeners, and water-repellent adjuvants. The safeners R-29148 and furilazole decreased injury from isoxaflutole when applied PRE. Corn injury increased from POST applications at the two-leaf and four-leaf stage of isoxaflutole mixed with safeners compared with isoxaflutole alone. The safeners may have acted as adjuvants to increase isoxaflutole absorption. The water-repellent adjuvants did not reduce injury when applied POST with isoxaflutole. However, the combination of safener plus the water repellent DC 1-6184 reduced corn injury from POST applications of lsoxaflutole. The water repellent DC 1-6184 reduced spray retention of spray solutions containing isoxaflutole or isoxaflutole plus safener.
