Best Insecticide for Roses- Reviews
1.Monterey LG6135 Garden Insect Spray
Monterey LG6135 is an OMRI certified organic insecticide that is completely safe for the environment.
Now the question:
Why it is an organic insecticide?
Because it contains spinosad as an active ingredient. Spinosad is a natural substance made by bacteria called Saccharopolyspora spinosa. Chemically, it is the mixer of spinosyn A and spinosyn D.
Spinosad is highly toxic to insects. If the insect ingests or comes in contact with it, the nervous system of the insect will disrupt and the insect kills within 1-2 days.
Generally, a small amount of spinosyn A is enough to kill the insect. But this insecticide contains 0.5% mixer of spinosyn A and spinosyn D that kill most of the destructive insects of roses including Japanese beetles, thrips, aphids, and sawflies.
Moreover, it is an odorless,fast-acting, and easy to spray insecticide that is safe for pets and humans.
To get insect-free rose bushes-
Mix 2 oz(4 tbsp) solution per gallon water, shake well, and spray on the entire foliage and soil.

So, Pick this environment-friendly, organic insecticidal spray for your roses and let it fight against insects for you.
2.BioAdvanced 701287A Miticide Pesticide Fungicide
Sound bluff? Let me explain-
The BioAdvanced claim that it is a 3 in 1 solution for gardeners. That means it acts as a pesticide, fungicide, and also miticide.
But I didn’t believe it. That’s why I started to research and want to know what I found?
It contains all the active ingredients that individually contain an insecticide, miticide, and fungicide.
As an insecticide-
It has 0.47% imidacloprid as an active ingredient. For those who don’t know what is Imidacloprid, It is a systemic insecticide that plants absorb through the xylem, redistribute the whole plants and keep away the insects from the rose plants.
It can kill almost 60 insects including all the destructive insects of roses.
But the question;
Is the systemic insecticide safe for plants? Yes, it is safe for the plant. In fact, it is a more eco-friendly insecticide. Because it can’t be washed out by rain. But it may be harmful to beneficial insects.
As a miticide, it has 0.6% Tau-fluvalinate that kills mites including spider mites and rose mites.
Lastly, It contains 0.65% Tebuconazole as a fungicide that prevents and treats fungal disease of roses such as black spots, powdery mildew, and rust.
Mix 5 tablespoons of concentrate solution per gallon of water and spray to control insects, mites and fungal diseases.
You may also pick the Ready to Spray formula to avoid premixing or pre-measuring. So, purchase the best systemic insecticide, fungicide, and miticide for roses and provide 360-degree protection to your roses.

As you see, it contains more tebuconazole. So, it is more powerful as a fungicide than an insecticide. Then why is it in my best insecticide list?
Because experts recommend it for use as a preventive insecticide. So if the insects are minimum and have a possibility to huge infestation, use it as a preventive purpose.
Mix 4 tablespoon of concentrate per quart water and pour the solution on a rose plant.
4.Spectracide HG-96434 Immunox 3-in-1 Insect & Disease Control

Finally, As a fertilizer- it has 0.2% available nitrogen (N),0.2% phosphate (P2O5) and 0.2% soluble potash (K20).That means the rose plants can absorb three primary nutrients(NPK) immediately after spraying on the plant.

It can’t wash off after applying on roses if it dries once and it comes with Ready To Spray (RTS) formula that acts fast against garden insects and diseases.
