Pressure and Screen Size Matters
Pressure and Screen Size Matters
The use of larger low pressure tips is recommended to prevent mortality in the living biological components of our products. Think of small high pressure tips as cheese graters. We recommend TeeJet™ - XR or XRC Tips
- Red Tip
- 20 psi 8 mph
- 30 psi 10 mph
- Max 40 psi 12 mph
- Brown Tip
- 10 psi 12 mph
- 30 psi 20 mph
- Max 40 psi 15mph

Pressure and Screen Size Matters
Pressure is the enemy of living Biologicals. Too much pressure causes the microbes to crush and leak all their insides out. The maximum pressure that our biologicals can survive is 50 psi we recommend a maximum working pressure of 40 psi as a safety net. With pressure comes the use of screens. Do not use a screen smaller than 50 mesh anywhere between the tank and the tip. Remember the cheese grater analogy.
The issue becomes most dangerous during turns on long booms.
Watch your pressure on stabilizing systems that employ pulse rate modulation. These systems are fully compatible with living biologicals, but care needs to be taken not to exceed their working pressures.

Pressure and Screen Size Matters
Cleaning Your Sprayer
Boom height is becoming a question we get a lot. We are less concerned with a positive effect biological than with a herbicide or other product that can impact neighboring fields.
Boom height is impactful in biologicals primarily effecting application rate and coverage. Banded spraying early has been shown to be very beneficial as product must land on the plant to bond with the tissues.
Product Spray on the ground will have reduced impact as the majority of the microbes are bonded with the plant within 20 minutes.

Water Conditioners and Chemistry
Cleaning Your Sprayer
Cleaning your sprayer is critical to the successful implementation of any living biological program. Contact with any chemistry that is antimicrobial can cause the death or reduced ability of the microbe to colonize your plants.
Be sure to clear and rinse the lines, valves and pumps on the sprayer not just the tank. Sprayer chemistry residue has proven to be the greatest challenge to getting successful results from Agrovive™ products.
Compatibility of chemistry is critical in the use of living biologics. Cleaning is critical but so is compatibility.
Purdue University provides a great look at how and what to mix together and how to properly mix chemistry to keep it vital in the tank.

Chlorinated water is hostile to microbial life in your sprayer. In the spring utilities are converting from well to surface water and tend to overcompensate with chlorine, causing issues for our products.
We recommend the use of a dechlorinator if you can smell the chlorine in the tank when you fill. These can be purchased from any pet store as a Chlorine and Heavy Metal Neutralizer.
IF YOUR WATER SMELLS LIKE A SWIMMING POOL IT PROBABLY NEEDS A DECHLORINATOR.
Well water is typically functional as long as it has not been near a chemical spill.
We had a producer use a well that had broadleaf herbicide contamination from a previous spill and we spent a year determining why his alfalfa yields were going down.
How to do a Jar Test

Water Conditioners and Chemistry
We recommend a jar test for any chemistry you intend to put in the tank with our product. The agricultural industry is inherently slow to provide recommendations regarding compatibility with any new class of products. This is the case with biologicals and biostimulants in general. We have found a few chemistries that are definitely not product compatible. The biggest being propiconazole. If it is your intent to use propiconazole at any time in the lifecycle of the plant keep in mind it will terminate the effectiveness of all Agrovive products post application. The use of a broad spectrum antimicrobial will in most cases kill the microbes in the plant good, bad or indifferent.
The use of a jar test is recommended when changing between chemistries in a sprayer as well.
An excellent video explaining how to perform a jar test is provided by Purdue University.
