To increase yield of marketable forced rhubarb and to break dormancy on plants receiving insufficient chilling: Apply 2 fluid ounces (60 mls) of a solution containing 20 grams a.i. in 10 gallons of water to each cleaned crown, when the rest period is not completely broken. When the rest period is broken by cold weather, apply 2 fluid ounces (60 mls) of a solution containing 10 grams a.i. in 10 gallons of water to each cleaned crown.
NOTE: Keep forcing house temperatures at 40° to 50°F for 24 hours after application. If house is warmer than 50°F, the crowns should be covered with plastic. Temperatures in the forcing house above 50°F will result in lower yields and poor stalk color.
