BonideAll Seasons Horticultural & Dormant Spray Oil, 32 oz Ready-to-Spray, Disease Prevention and Insect Killer for Organic Gardening

Very effective at killing leaf rollers on my cannas, which was the main reason I bought it. Very mild to no scent. Very easy to use, good value. Doesn’t leak. Doesn’t leave any weird color residue on plants.

I bought this to try to stop the scale on a Magnolia tree with special emotional significance for my wife.Two coatings later, the tree is doing well, scale has been reduced exponentially.Well worth the cost, especially with the built-in spray bottle.

I've found that this product is the only pesticide I need to adequately protect my small yard from insects and fungus. Carefully used, it keeps the worms out of my apples, eliminates sooty mildew, controls other fungus well enough, and two years ago it defeated a horrendous invasion of thrips that threatened to devastate practically everything. I prefer this brand to others because it is less viscous, easier to handle and seems to spread better. I definitely do not recommend the hose-end sprayer however. The basic problem is that it is poorly calibrated (at least for my water pressure) and will quickly empty the entire container. This is very expensive and covers plants with an excess of oil to no benefit. Moreover, you have poor control over where this torrent of water and oil goes; you are likely to get an oily residue on yourself, your house windows, your car and maybe your neighbors. I just mix the recommended amount in a one or two gallon pump sprayer. It is much less expensive this way, less messy and just as effective.

When your fruit tress require horticultural oil, the Bonide Horticultural Oil is a good choice. Applied with a garden hose, the application takes no time at all and the bottle has lasted for many applications. A safe, easy to apple method of killing off those nasty bugs that destroy the fruit.

My holly bush was being destroyed rapidly by scale insects and by spider mites.Luckily. this product worked 100% destroying the destructive insects and now the bush is thriving again with new leaves. Nothing else worked but this product. Thank you.

But effective once you get it on the plant.

i am usually confounded by devices, but i found the sprayer super easy to use and very efficient. i saw a review to the contrary, so i wanted to say i didn't find any problems at all.

Easy to use, mites are gone and now have new growth emerging
