Potatoes

ROYAL MH30 XTRA 

(maleic hydrazide)

• Do not apply ROYAL MH to potatoes to be used for seed purposes.
• Apply ROYAL MH to potatoes within the period between two to three weeks past full bloom and two weeks before expected date of top kill or first frost.
• Do not apply too early. Applications made prior to proper sizing of tubers can reduce yields. The majority of tubers should be at least 4 - 5 cm in diameter if they are to reach a minimum size of 110-170 grams (4 – 6 ounces) at harvest.
• Uneven or excessive application may result in reduced efficacy and physical disorders such as bud end cracking and/or elephant hide.
• Do not apply ROYAL MH after the upper leaves have turned from dark green to a light green or yellow colour as insufficient material will be absorbed and translocated from the leaves to the tubers – thus giving unsatisfactory sprout control.
• Best results are obtained when ROYAL MH is applied under slow drying conditions (i.e. during early morning hours or on cloudy days).
• Do not apply if daily temperatures are expected to exceed 30^oC, as high temperatures and low humidity will cause the material to crystallize on the leaf surface and not be absorbed into the plant.
• Apply at least 24 hours before rainfall or irrigation.
• Do not spray when wind velocity exceeds 15 km/hr.

SPROUT NIP EC

• Prepare 1% emulsion by adding 1 L of product to 35 L of water.  Stir to form a uniform emulsion.
• Treatment normally occurs when 2 weeks have elapsed after harvest to allow tuber wounds to heal.
• Apply to potatoes in the packing line.
• Set spray nozzle in packing line between the cleaning equipment and the packing equipment.
• In packing lines equipped with brushes, place the spray nozzle on the output side of the brushes.
• In wash lines, place the spray nozzle on the output side of the dryer rolls.
• A shield should be in place around the spray table/conveyor belt to prevent spray mist drift.
• Contact with the buds on the tuber is essential.
• Dirt on the potato may prevent product from reaching the buds.
• Do not apply in the field.
• Do not use on seed potatoes.
• Store treated potatoes away from seed potatoes.
• Do not put seed potatoes in bins which have been exposed to this material.
• Thorough cleanup of storage bins is necessary following removal of potatoes — sweep out bins, wash crystallized material off machinery, fans, ducts and walls with alcohol or light oil, then hose out bins thoroughly with water and aerate.
