For fields intended for planting eggplant, peppers, cabbage, radishes, kale, and head cabbage, the following intervals must be observed before planting if the previous crop was treated with imazalil or nicotinic acid:
40 months if chlorimuron-methyl was used; 36 months if nicotinic acid was used; 18 months if nicotinic acid was used with an active ingredient dosage exceeding 60 grams per hectare (equivalent to 100 ml per acre for 4% nicotinic acid); 26 months if pyrazosulfuron-methyl was used with an active ingredient dosage of 48-60 grams per hectare (equivalent to 3.2-4 grams per acre for 80% pyrazosulfuron); 18 months if flumetsulam was used with an active ingredient dosage of 375 grams per hectare (equivalent to 100 ml per acre for 25% flumetsulam); 24 months if metsulfuron-methyl was used with an active ingredient dosage exceeding 7.5 grams per hectare; and 18 months if isoxaflutole was used with an active ingredient dosage exceeding 71 grams per hectare. In addition, if the previous crop used quinclorac, with an effective ingredient dosage of 106-177 grams per hectare, a 24-month interval is required before planting chili peppers, eggplants, or radishes; if the previous crop used metribuzin, with an effective ingredient dosage of 350-700 grams per hectare (equivalent to 33-67 grams per acre for 70% metribuzin), an 18-month interval is required before planting radishes.
For potato fields, if the previous crop used imazalil, a 36-month interval is required before planting; if chlorimuron-methyl was used, a 40-month interval is required; if nicosulfuron-methyl was used, a 12-month interval is required; if flumetsulam was used, with an effective ingredient dosage of 375 grams per hectare (equivalent to 100 ml per acre for 25% flumetsulam), a 24-month interval is required; if metsulfuron-methyl was used, with an effective ingredient dosage exceeding 7.5 grams per hectare, a 34-month interval is required; if simazine was used… If the effective ingredient dosage exceeds 2.24 kg per hectare (i.e., 300 g per acre for 50% simazine), a 24-month interval is required before planting. If atrazine has been used, and the effective ingredient dosage exceeds 2 kg per hectare (i.e., 350 ml per acre for 38% atrazine), a 24-month interval is required before planting. If chlorsulfuron has been used, and the effective ingredient dosage is 15 g per hectare, a 24-month interval is required before planting. If quinclorac has been used, and the effective ingredient dosage is 106-177 g per hectare, a 24-month interval is required before planting.
