Dodder (Cuscuta spp.)-general infestations in carrot seed fields

pendimethalin (Prowl H2O)

Carrots for seed only

Rate 0.5 to 2 lb ai/a

Time Apply after the last normal cultivation (layby) as a directed spray.

Remarks Use 3 to 4 pints/a to control dodder. Apply directly to soil between rows. Spray should not contact carrot plants. Lay-by applications can be in carrots previously treated with herbicides registered for use in carrots. Prowl most effectively controls weeds if adequate rain or irrigation follows within 7 days.

Caution Do not use on peat or muck soils. Do not plant winter wheat or winter barley in fall after Prowl application at rates above 3 pints/a. Do not feed or graze carrots after application. Do not use screenings from seed processing as feed for livestock.
