Monterey Organic Horticultural Oil Quart
Monterey Organic Horticultural Oil Quart
Monterey Organic Horticultural Oil (Qt) combines 80% pure mineral oil with 92% unsulfonated residue to physically suffocate soft-bodied insect life cycles and fungal pathogens. This dual mechanism neutralizes eggs, larvae, nymphs, and adults of pests while disrupting spore attachment to combat powdery mildew and rust. Growers can deploy the formula year-round during dormant periods to clear overwintering threats or throughout the active season to sustain crop resilience.
Suitable for fruit trees, vegetables, berries, flowers, and turfgrass, the quart-sized concentrate targets mites, aphids, scale insects, leafminers, and fungus gnats. Apply thoroughly during calm weather conditions, ensuring complete surface contact while avoiding treatment under drought or extreme temperature stress. Its low environmental impact and targeted delivery support integrated pest management frameworks and organic certification requirements for sustainable landscape maintenance.

Let customers speak for us
Really nice soil and awesome service
Never used because I ordered the wrong Water Filter. Mike was very helpful with the return and refund. Excellent Customer Service.
Great service. Soil is what I wanted and it off loaded exactly where I asked.
Plants are doing really well with this soil. Deep and rich looking soil, plants seem really happy. Much more cost effective (and no plastic bag waste) compared to buying bags of soil mix from a store.
The quality of the craftsmanship is superb! My formula one fan absolutely loves it!!!!
Worked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
