Osmopro is a naturally occurring glycine betaine. In plants, glycine betaine acts as a protectant by adjusting the osmotic balance inside the plant cells and tissue. This anti-stress agent helps the plants overcome environmental stress situations, like drought, high and low temperatures and soil salinity.

Improves Flower Retention & Fruit Setting

Glycine Betaine

Glycine Betaine is a water soluble osmoprotectant found in many organisms and plants. In nature, it is synthesized and accumulated in response to environmental stress to protect the plant cell. When sprayed on the plant canopy, OsmoPro penetrates through the plant surface and translocates throughout the plant within 24 hours and remains metabolically active for a minimum of 21 days. 

Prevents Cherry Cracking

The permeable skin of cherries allows surface water into the fruit, equalizing the osmotic potential in the fruit. This process causes the cherries to swell and crack.

OsmoPro treats over 45,000 acres of cherries worldwide each season.

Prevents Tip Burn in Salad Crops

High humidity and limited ventilation disrupt calcium migration to the growing peripheral tissues, causing necrosis. OsmoPro promotes the retention of nutrients under cover and in the field. 

Prevents Bitter Pit in Apples

This disorder is the result of a lack of calcium in the fruit. With OsmoPro, Calcium and Boron are quickly absorbed by leaves supported by the presence of glycine betaine which is ideal for treating bitter pit in apples and blossom end rot in tomato and capsicum.

Prevents Citrus Greening 

Citrus studies with Osmopro have shown  5% or better fruit set increases at rates of about 4.4 pounds/acre with equal weight per fruit.

Mode of Action

OsmoPro acts as an osmoprotectant in the plant, regulating water flow between the inside and the outside of the plant cell. 

Under conditions of environmental stress,  OsmoPro helps to maintain the normal osmotic balance and thereby plant cell metabolism resulting in enhanced photosynthesis and nitrogen fixation.

In a well hydrated plant with good quality water there is an osmotic balance within the cell.

When there is excessive external water, such as in high humidity and/or high levels of rain, the outer cell solution becomes more dilute (hypo-osmotic), water flows into the cell, ultimately causing it to swell which, if allowed to continue, can lead to breaking of the tissue and cracking in fruit

With extreme temperatures or high salinity, the outside cell solution concentration is higher than the inner (hyperosmotic) and water flows out of the cell to redress the osmotic balance. This can lead to enzyme and protein denaturation, blocked cellular reactions, and impaired cellular processes such as photosynthesis, respiration, etc.
