Crown MH

MODE OF ACTION OF CROWN MH:

CROWN MH is an innovative growth regulator for tubers, intended for field application, which effectively controls the sprouting process. Its use results in the highest quality and significantly extends the storage period of potatoes. The product prevents sprouting of tubers both during storage and young tubers already in the plantation, minimising developmental defects (proliferation) and secondary growth. Additionally, CROWN MH protects tubers against stress caused by drought, helping to maintain their optimal quality.

Benefits of using Crown MH:

- Inhibition of unwanted sprouting of tubers during vegetation.

- Reduced tendency for internal sprouting and secondary growth of tubers.

- Prevention of potato volunteer growth in subsequent crops, contributing to maintaining phytosanitary hygiene of the field.

- Inhibition of sprouting of tubers remaining in the field after harvest.

CONTENT OF ACTIVE SUBSTANCE IN CROWN MH:

maleic hydrazide* (substance from the hydrazide group) – 270 g/l

*in the form of potassium salt – 360 g/l

Dosing of Crown MH:

Potato

Prevention of tuber sprouting during storage

Maximum / recommended dose for single application: 11.0 l/ha.

Application timing: apply the product 3 to 7 weeks before desiccation of the plantation or the beginning of natural plant senescence, from the end of the flowering phase of the first inflorescence to the end of the ripening phase of berries and seeds (BBCH 69-89).

Maximum number of treatments per growing season: 1.

Recommended water volume: 300 – 600 l/ha.

Recommended spraying: medium droplet size.

Note: the product applied at the above timing and dose also contributes to limiting sprouting of tubers left in the field ("potato volunteers").

Onion, shallot, garlic

Prevention of sprouting of green shoots during storage

Maximum / recommended dose for single application: 8.9 l/ha.

Application timing: apply the product when 10% to 50% of plants in the plantation have a dried neck and broken green shoots, i.e. about 10-15 days before harvest (from BBCH 47-48).

Maximum number of treatments per growing season: 1.

Recommended water volume: 500 – 600 l/ha.

Recommended spraying: medium droplet size.

CROWN MH - PRE-HARVEST INTERVAL:

 

Onion, shallot, garlic – 4 days

Potato – 21 days
