Monterey Horticultural Oil - Organic Gardening Fungicide, Insecticide, & Miticide - Use for Aphids, Mites, Scales - 15 oz

Works good on conifers, will buy again and again...

The horticultural oil works great on a lot of plants. I used it in my vegetable garden this past spring and on our apple trees and flowers. I combined it with an organic bug spray which worked great. The horticultural spray helps to prevent fungus and helps to prevent infestations of bugs.

Used it to spray my apple tree. So far, seems to work. I haven’t noticed any pests.

I don't know why I haven't tried this earlier. I've tried nearly every other method for insect control (below) and this wiped out nearly everything that has been killing my plants when nothing else has worked. And, it did a great job, while not hurting my plants. I get that some of the insects mentioned below are considered helpful in some circles, but my plants (and house) were being overrun by these critters... and they were dying from the infestations! Now, all the visible insects are dead and I am happy. There might be a few spider mites or mites laying around but their population has greatly reduced after, sadly, killing two of my oldest plants. So, this does work! I would recommend! Though, what I didn't know was horticultural oil is made of mineral oil (derived from petroleum), but it is organic. So, pick your battles. For me, it was all the insects killing my plants. Good luck out there! I've tried: Pyrethrin, beneficial nematodes, B.T., insecticidal soap, "deadbug brew", essential oils, gnat traps, etc. My biggest problems: fungus gnats, spider mites, mites, greenhouse millipedes

This product doesn’t keep cats from pooping in your yard. While sprinkling it you have to be careful that the product doesn’t get into your nostrils. Not a great solution to pest

I purchased this to kill mites on my crepe myrtle. Worked with one application.

This oil works as described. Although not long lasting it will cure fungus until a more permanent solution is made

works like it should
