Azatin O Insecticide - 32oz - OMRI Listed

Azadirachtin Growth Regulator Insecticide, 32oz

Many insecticides only address adult pests, leaving eggs and larvae to hatch into the next generation days later. Azatin O uses azadirachtin as an insect growth regulator, disrupting molting and development at the larval stage so pest populations don't rebound as quickly between applications.

This 32oz bottle is labeled at a 4-16oz per 100gal rate across ornamentals, vegetables, herbs, and berries in greenhouse, nursery, hydroponic, and turf settings, with a 4-hour REI.

Key Features & Benefits

• Azadirachtin active ingredient — an insect growth regulator that disrupts larval development and molting rather than killing on contact alone.
• Soft on beneficial insects — fits into an integrated pest management program without the broad knockdown of many conventional insecticides.
• Broad crop and site labeling — covers ornamentals, vegetables, herbs, and berries across greenhouse, nursery, hydroponic, and turf sites.
• 4-16oz per 100gal application rate — scalable dilution for different pest pressure levels.
• OMRI Listed, 4-hour REI — suited to organic production with a same-day crew re-entry window.

Who Should Use This

This fits growers managing larval-stage pests across ornamentals, vegetables, herbs, or berries who want a growth-regulator option that spares beneficial insects, whether in a greenhouse, nursery, hydroponic system, or turf setting.

Frequently Asked Questions

How does an insect growth regulator like Azatin O work

Azadirachtin, the active ingredient in Azatin O, disrupts molting and development at the larval stage rather than killing adult pests on contact. That interrupts the pest's life cycle, which can reduce how quickly a population rebounds compared to an adult-only knockdown product.

What is the application rate for Azatin O

It's labeled at 4 to 16oz per 100 gallons, with the specific rate depending on pest pressure and the crop being treated. Always follow the full label rate table for your specific site and target pest.

Is Azatin O safe to use around beneficial insects

It's marketed as soft on beneficial insects compared to broad-spectrum chemical insecticides, which is why growers running an integrated pest management program often choose it. Confirm compatibility with your specific beneficial species before relying on it across a full program.

What crops and sites is Azatin O labeled for

It's labeled for ornamentals, vegetables, herbs, and berries in greenhouse, nursery, hydroponic, and turf settings. That broad labeling makes it usable across most of a diversified operation rather than a single crop type.

What is the re-entry interval for Azatin O

The labeled REI is 4 hours, with a Caution signal word. Follow the complete label for site-specific application and safety directions beyond the re-entry interval.
