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.

Fit and Length
Size: X-Large, Color: (401) Royal / / White
Yeah this fits perfectly. Very soft, the color pops, keeps you warm. I use these under my sweatshirts, cable sweaters, and my flannel shirts. For me it's about the arm length and how well the item contours to the body to help with warmth. Thank you for getting this right.

Worth it.
Size: Small, Color: Black (001)/White
Living in North Dakota, staying warm is invaluable. UnderArmour Cold Gear is the only base layer the provides warmth, KEEPS warmth, and protects from the unforgiving wind. Every winter I go on the hunt for thermals, layering options and I always find others to be saggy or incredibly tight, either way, once I begin shoveling or snowblowering, and sweating, other products become soaked, sticking to skin, unbreathable and quickly your sweat stuck to your body under layers in now creating a cold,chill, freeze to your body, and on a -10F day, it can become a dangerous situation. I honestly was hesitant to purchase UnderArmour, I felt it was too hyped up or paying for a name. BUT IT IS NOT. UnderArmour isn't a name, it is a company that has made the highest quality base layer, warmth, breathable and it really wicks sweat away; I may not know how it does it, but it works! For sizing, I ordered a small in the women's longsleeve/turtleneck black coldgear. I'm 5ft and roughly 110lbs. I like the fit, it is meant to fit your body. I probably could wear an extra small, but I like the sleeve length in the small and it fits very well. Stay warm folks!

Tight but stays in place, comfy and keeps you warm
Size: Medium, Color: Charcoal Light Heather (019)/Black
I liked this shirt because it keeps me warm when I'm outside even at negative temperatures, I can work out comfortably in it and the sweat dries out soon; also, the interior of the shirt is made of a very comfortable material. I don't like that this is very tight, cool if you want to use it under your usual sports clothes but if you want to use it as is I would suggest going up a size. I use this shirt almost every day to work out during winter time, I've washed them several times and they still feel as comfortable as the first day.
