摘要

Calendula is an alternative oilseed crop whose seed oil is valued as a substitute for tung oil and a replacement for petroleum-based volatile organic compounds in paints and other coatings. Calendula tolerances to most POST-applied herbicides are unknown. Two POST-applied herbicides were tested for tolerance by calendula. Imazamethabenz at 0.44 kg ai ha-1 plus surfactant and desmedipham plus phenmedipham at 0.36+0.36 kg ai ha-1 were tolerated by calendula, but the latter herbicide must be applied after the four-leaf-pair stage of growth to avoid severe injury. Neither herbicide adversely affected calendula seed yield if applied at the four-leaf-pair stage. Because these herbicides can control several weed species, calendula tolerance to them may encourage more growers and crop advisors to test this new oilseed crop on commercial farms.CAS Registry Numbers 13684-56-5 100728-84-5 81405-85-8 13684-63-4
