How much do I use?

Two gallons of GRO per acre will result in 40 lbs of available nitrogen. The same 2 gallons at or before planting will make a significant surge in phosphorus availability.

2 gallons, post emerge will increase protection of plants from powdery mildew, fusarium, phytophthora, pythium root rot and other pathogens. If conditions get unusually wet, another application might be useful.

Plants will flower 10 days earlier and will mature more uniformly.

If using GRO, reduce nitrogen by 40-60 lbs and phosphorus by 15 lbs.

In an organic cropping system, the actinomycetes combined with naturally occurring carboxylic acids from the microbial respiration will typically provide full season control of pathogens.

Increased yields result from improved nutrient utilization, healthier plants and extended root growth.

Soil applied TP will yield the greatest benefits but a foliar application can be useful when airborne pathogens are present.

CAUTION - Do not use Ridomil or other mefenoxam or metalaxyl products with GRO.
Theses systemic fungicides are non-selective in toxicity to soil organisms.
