Product information

Royal MH 30 is a growth inhibitor for the prevention of potato and onion germination during storage and the control of primary and secondary children in tobacco.

Treated plants: Onion, Potato, Tobacco

Mode of action:
After application, Royal MH 30 enters the plant and migrates into tissues, where it is translocated throughout the plant: in buds, infants, and other growing areas. 

Royal MH 30 acts by absorption at the foliar level and translocates through the conducting vessels in each organ of the plant. In the bud, it mainly inhibits the respiratory processes in the cell, reduces enzymatic activity, and slows down cell proliferation.

Advantages of using Royal MH 30:
- It has high effectiveness in controlling the germination of potato tubers and onion bulbs;
- Protects the quality of potato and onion production during transport and storage, as well as the quality of tobacco leaves;
- Depresses the development of babies for 7-8 weeks;
- Increases yield by 6-7% per hectare;
- Ensures proper quality for marketing.

How to use it:
It is applied during the vegetation period, on healthy and turgid plants, so as to ensure a good absorption in the plant. 

-Use Royal MH 30 within 24 hours of topping (end of the budding period in 80% of plants, leaf length not less than 15-20 cm).
-Manual application: apply 15-20 ml of the solution to the plant, moistening the upper part of the plant well.
-Mechanical application: appropriate treatment equipment is used, using fine jet nozzles, conical type, to ensure good wetting of the upper half of the plant.
-The first signs of action on young children and freshmen appear 7 days after the application of the treatment, being followed by their total drying.
-The recommended solution volume is 500 - 600 liters / ha.
-Break time: 14 days

Onion and potato:
- Is applied at the time of culture maturation, having the role of blocking cell division and sprouting production in storage spaces.
- For onions: the treatment is applied at the beginning of the physiological fall of the culture when the first 2-3 leaves fall on the culture.
- For potatoes: the treatment is applied when the potato has finished cell division and begins to grow by filling the cells with starch. The moment is determined by measuring the tubers in the bead. They must be at least 25 mm in diameter, and the number of tubers must be characteristic of the variety.
-Apply the product evenly over the fallen leaves (without dew). To get a good result, bathe the upper half of the plant and apply the treatment early in the morning, on days with overcast skies or 1-2 days after irrigation.

Crop  Dose  Application moment 
Potatoes  16 liters/ha During the vegetation period, at the time of flowering
Onion  12 liters/ha During the vegetation period
Tobacco  20 liters/ha Within 24 hours of topping

- The temperature should not exceed 26ºC, at the time of application, because the effectiveness of the product depends on the amount of active substance absorbed.
- Avoid applying the treatment on wilted plants or on windy days.
- Do not use tobacco seeds on crops and avoid bathing neighboring crops.
