Monterey Horticultural Oil (Qt) offers a versatile solution for year-round usage, whether during the dormant or growing season. This product was previously known as SAF-T-Side horticultural oil by Monterey Lawn and Garden.

Now, it has a different name but is still effective in controlling fungal diseases, insects, and mites. Monterey Horticultural Oil can be used on many different types of plants, such as fruit trees, vegetables, berries, flowers, and grass.

Monterey Horticultural Oil (Qt) is an invaluable tool for addressing pest problems and plant diseases in a wide range of crops. With its ability to target specific pests such as soft scales and control pest populations, it plays a crucial role in pest management strategies. By suffocating eggs, larvae, nymphs, and adults of soft-bodied insect pests, Monterey Horticultural Oil effectively reduces pest populations and minimizes pest damage to plants.

Additionally, its fungicidal properties make it effective against various plant diseases, providing comprehensive protection for crops. Monterey Horticultural Oil helps growers control pests and keep plants healthy. It also makes plants more resistant to pests, reducing damage from insects and diseases.

Mode of Action: Suffocation and Fungicidal Properties

The mode of action of Monterey Horticultural Oil is twofold. Firstly, it suffocates eggs, larvae, nymphs, and adults of soft-bodied insects by creating a physical barrier that prevents oxygen from reaching them. This suffocation mechanism effectively controls pests without the use of harsh chemicals, making it a safer option for both plants and the environment. Secondly, as a fungicide, it disrupts the attachment of pathogens to the host plant and suffocates the organism, providing reliable control of fungal diseases such as powdery mildew and rust.

Key Ingredient: Mineral Oil

The primary active ingredient in Monterey Horticultural Oil is mineral oil, comprising 80% of the formulation. Specifically, it contains 92% unsulfonated residue of mineral oil, ensuring high purity and efficacy in controlling pests and diseases. Mineral oil has long been recognized for its effectiveness in pest and disease management, making it a trusted choice for growers seeking safe and reliable solutions for their crops.

Wide Range of Pest Control

Monterey Horticultural Oil can eliminate various pests such as mites, aphids, scale insects, leafminers, fungus gnats, and other small insects. This oil is effective in controlling a wide range of pests in the garden.

Monterey Horticultural Oil is a versatile solution for pest control in the garden. Its broad-spectrum activity makes it a valuable tool for integrated pest management (IPM) programs, where multiple pests need to be targeted simultaneously. By controlling pests at different stages of their life cycles, this product helps prevent infestations and minimize damage to crops.

Application Guidelines

When using Monterey Horticultural Oil, thorough spray coverage is essential to ensure effective control of pests and diseases. The product should be applied according to label instructions, taking into account factors such as plant type, growth stage, and environmental conditions. It is recommended to apply the oil during calm weather conditions to minimize drift and ensure even coverage. Additionally, it is important to avoid spraying plants under stress, such as those experiencing drought or extreme temperatures.

Benefits of Year-Round Usage

The ability to use Monterey Horticultural Oil year-round provides growers with flexibility in managing pest and disease issues. During the dormant season, application of the oil can help prevent overwintering pests and diseases from establishing populations in the spring. In the growing season, regular applications can maintain plant health and vitality, ensuring optimal growth and productivity. By incorporating Monterey Horticultural Oil into their crop management practices, growers can achieve healthier plants and higher yields throughout the year.

Environmental Considerations

As a low-impact pest and disease control option, Monterey Horticultural Oil is suitable for use in organic farming and gardening. Its minimal environmental impact and safety for beneficial insects make it a preferred choice for growers seeking sustainable solutions. By minimizing the use of synthetic pesticides and promoting natural pest control mechanisms, Monterey Horticultural Oil contributes to the overall health and balance of agroecosystems.

Effective and Versatile Pest Management

Monterey Horticultural Oil (Qt) offers growers a safe and reliable solution for controlling pests and diseases year-round. With its suffocating action on soft-bodied insects and fungicidal properties against fungal pathogens, this product provides comprehensive pest and disease management for a wide range of crops.

Title: Reliable, Easy-to-Use, and Worth Every Penny
Style: 32 oz
I’ve been using Slime tire sealant for my fat tire e-bike, and I can say with confidence that this product delivers exactly what it promises. The application is simple, the results are consistent, and the peace of mind it provides is invaluable. For anyone who rides regularly — whether for commuting, recreation, or deliveries — this is a product that pays for itself many times over. The first thing I appreciate about Slime is how easy it is to install. The bottle is well-designed, the instructions are clear, and the process takes just a few minutes. You simply deflate the tire, remove the valve core, squeeze in the recommended amount, reinstall the valve core, inflate, and spin the wheel to distribute the sealant evenly. No special tools, no mess, and no guesswork — just a straightforward, user-friendly process. Performance-wise, Slime does exactly what it’s supposed to do: seal punctures quickly and effectively. I’ve had nails, thorns, and sharp debris puncture my tires while riding, and in every case where the leak was within the tread area, Slime sealed it instantly. There’s something incredibly reassuring about hearing that faint hiss of air for a second, then watching it stop as the sealant does its job. It’s a real-time reminder that this product is actively protecting you from being stranded. What sets Slime apart from other sealants I’ve tried is its durability. Once applied, it stays active inside the tube for months, ready to respond to new punctures as they happen. It doesn’t dry out quickly, it doesn’t clump up, and it doesn’t cause balance issues with the tires. For someone who rides almost daily, that reliability is a huge plus. Another thing I respect about this product is that it’s non-toxic and environmentally friendly. If a bit of sealant escapes during a repair, I don’t have to worry about it harming the environment. It’s also water-soluble, making cleanup easy if I ever need to replace a tube or tire. That attention to safety and sustainability shows that the company isn’t just making a great product — they’re doing it responsibly. The value for the price is excellent. One bottle goes a long way, and when you factor in the cost of replacing tubes, paying for roadside repairs, or even the inconvenience of being late because of a flat, Slime is an investment in both savings and peace of mind. For delivery riders like me, it’s especially valuable — every flat avoided means another day of work uninterrupted. In short, Slime is one of those rare products that I can recommend without hesitation. It’s easy to use, effective, long-lasting, and backed by a company that clearly understands the needs of cyclists and e-bike riders. It has already saved me from countless headaches, and I plan to keep a bottle on hand at all times. If you ride regularly and haven’t tried it yet, you’re taking an unnecessary risk — this is one of the best preventative tools you can add to your maintenance kit. Verdict: Five stars for performance, ease of use, and overall value. Slime is a must-have for any serious rider who values reliability and wants to keep rolling no matter what’s on the road.

Slime is good, pump is a disaster
Style: 1 gal, Style: 1 gal
The only reason I am giving this a 4 star(not zero) rating is the slime itself. The actual pump on the 1 gallon canister is awful. It makes so much mess, so I do not know whether I pumped the slime into the tubes or it all just spilled out of the base of the pump. The bottles worked great, but this time I needed to use more slime for a bunch of tires. What a slimy mess that was. Very poor pump design. Only after I spilled who knows how much of the slime, I finally washed it and was able to see the problem. The cap at the base of the pump got unscrewed and let all the slime lose. I screwed it back up and this should fix the mess next time I use it. Just a heads if someone encounters the same issue.

Fixes flats and old tires like a charm
Style: 1 gal
This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.

slime is and has always been amazing for bike tires and other small pneumatic tires
Style: 1 gal
this is a great value, I have been using slime in my tubes of my bikes and a small inflatable pneumatic tires for probably 30 years, and I can say slime has only improved, and it works fantastic, this is a very good way to save money, and it works great on goat heads and several other ways your tires can get punctured, I still always recommend carrying a small air compressor or pump, but for the price point you just cannot beat slime, every bike shop should always carry this.
