Phosphorus Pro
Phosphorus Pro is a high-phosphorus fertilizer that supports fruit maturation and ripening and corrects phosphorus deficiency. Phosphoric acid and mono-potassium phosphate deliver readily available phosphorus where energy transfer and rooting demand it.

Pre-harvest and re-entry intervals are restrictions carried on pesticide labels. These products are not pesticides, so neither applies. For comparison, four hours is the shortest re-entry interval a registered pesticide can carry.
High-phosphorus fertilizer from Vegalab Crop Science, powered by Phosphoric acid, mono-potassium phosphate. Phosphorus Pro targets Fruit ripening, phosphorus deficiency, root development.

A high-phosphorus water-soluble fertilizer applied as fruit begins to mature, supporting the energy metabolism that drives fruit maturation and finish, and correcting phosphorus deficiency on acid or cold soils.

Derived from: Mono-potassium phosphate · Phosphoric acid
Contains: Citric acid
Why is phosphorus often limiting?
Phosphorus powers energy transfer, root development and fruit maturation, yet it is one of the least mobile and most easily locked-up nutrients in soil - bound forms simply are not available to the plant. So crops can show phosphorus shortage even on soils that test adequate, particularly as fruit matures and demand spikes.
How does Phosphorus Pro work?
Phosphorus Pro (0-29-5, from phosphoric acid and mono-potassium phosphate) supplies highly available phosphorus with potassium. The readily available phosphorus supports the energy-intensive process of fruit ripening later, while correcting deficiency where soil phosphorus is tied up and unavailable.

The registered label states the window as "when fruits start to mature" and "after fruits begin to thicken" across all crop groups, and carries both foliar and soil rate columns. There is no establishment or planting window on the label.
Always read and follow the applicable product label.
Apply when fruits start to mature and again after fruits begin to thicken, two to three applications. The registered label allows both routes: the product can be applied directly to the plants or to the soil. Matching timing to that window gives the clearest response, since that is when the crop most needs available phosphorus.
Which crops is it for?
Phosphorus Pro has been tested on cereals, vegetables and tree fruit - crops where strong rooting early and good ripening later both depend on phosphorus availability. It is especially useful on soils prone to phosphorus lock-up.
How does it support rooting and ripening together?
Phosphorus underpins both the energy transfer that builds roots and the maturation processes that finish fruit. By supplying it in a highly available form at the two windows where demand peaks, Phosphorus Pro supports fruit maturation and harvest quality from a single product, with potassium backing both phases.

What does Phosphorus Pro target?
Fruit ripening, phosphorus deficiency, fruit maturation
What is the application rate for Phosphorus Pro?
1:1,000–1:400 · 1–2.5 mL/L (3.8–9.5 mL/gal) · 1.25–2.5 L/ha (17.3–33.3 fl oz/acre) Application: Foliar spray or soil application when fruits start to mature and after fruits begin to thicken, 2–3 applications.
Is Phosphorus Pro suitable for natural or organic programs?
Phosphorus Pro supplies Phosphoric acid, mono-potassium phosphate in a formulation designed to fit low-residue and IPM programs.
What is Phosphorus Pro for?
Fruit maturation, ripening and correcting phosphorus deficiency.
What is the analysis?
P2O5 29.00%, K2O 5.00%, B 0.50%, Mo 0.50% (NPK 0-29-5).
When should I apply it?
When fruits start to mature, and again after fruits begin to thicken.
Which crops is it for?
Cereals, vegetables and tree fruit.
Why is available phosphorus important?
Soil phosphorus is easily locked up; a highly available form ensures the crop can use it at peak-demand stages.
