Get diseases under control
Pinion promotes a healthy leaf surface that doesn’t allow diseases to proliferate. In our field trials, Pinion has provided comparable powdery mildew control as powerful conventional fungicides, and superior control to organic fungicides.
Safe, effective, and easy to apply
Non-phytotoxic, even under sensitive conditions
True liquid; tank mixes well with other AEA products
Flexible application: Can be used both at the onset of pressure and after symptoms appear
Minimal reapplication—often just one spray at the start of pressure season
How Pinion Works
Pinion functions through a combination of pesticidal effects from its active ingredients (citric acid and cinnamon oil), along with creating a physical barrier on the leaf surface through our proprietary blend of ingredients.
The result is disease control that integrates into a regenerative system by fostering healthy leaf surfaces without disrupting plant biology.
We have tested its effectiveness against powdery mildew and fireblight in field trials, while many other field trials are underway. Its mode of action can be effective against other fungal and bacterial infections as well.
Getting Back to Our Roots
Powdery mildew control is what got AEA started back in 2006, with John Kempf’s famous “aha” moment. John’s experience with 2 neighboring melon fields—one with a disastrous powdery mildew infection while the other was virtually untouched—set him on a journey exploring plant health that got AEA to where we are today.
Pinion can help you find your own “aha” moment when you experience a healthy planting free of powdery mildew.
Field Trials
- Wine Grapes
- Organic Wine Grapes
- Pumpkins
- Fireblight
Wine Grapes
A conventional vineyard in Temecula, CA designated a control block that was treated with conventional fungicides, and a treatment block that was treated with Pinion. The experimental block has a history of high disease pressure, including a complete crop loss from powdery mildew 2 years ago.
Comparable control to fungicides
AEA’s agronomist walked 6 rows in the treatment block and only observed a single grape with powdery mildew
Organic Wine Grapes
An organic vineyard in Napa, CA is in an area with historically high powdery mildew pressure, to the extent that a neighbor gave up and ripped out an entire vineyard. This year, the vineyard applied stylet oil 4 times before Pinion was available. After receiving Pinion, the vineyard designated control and treatment blocks; the control received 3 more stylet oil applications while the treatment got 2 applications of Pinion at a rate of 4 quarts per acre.
Superior Control
Pinion provided superior control to organic stylet oil
Fewer active infestations
39% of observed clusters in the control block had active mildew infestations, while 31% did in the treatment block.
59% less severity
But the greatest reduction was in severity: we noticed a 59% reduction in the severity of powdery mildew in the treatment block.
Pumpkins
Pinion was applied to organic pumpkins when powdery mildew symptoms had begun (Day 0 in photo) “I wouldn’t have believed this was possible, if I hadn’t seen it with my own eyes.”
The mildew immediately stopped progressing, and gradually faded away.
Meanwhile, in an untreated plant nearby, the mildew completely ravaged the leaves.
Fireblight
Pinion was applied to Florida Loquat when fireblight began to show.
The new growth that developed afterwards was perfectly healthy, and fireblight-free.
An untreated tree had fireblight on about 70% of new leaves.
