Review: This stuff saved my hydroponic garden! - I began growing strawberries indoors hydroponically this summer and suddenly had a problem with older leaves beginning to turn brown and die. Since I am a troubleshooter by nature, and a total noob with hydroponics, I immediately thought that my hydroponics solution was the culprit the entire time. After spending loads of money on new strawberry plant replacements, new containers, new hydroponic nutrients, I was about to simply give up on my indoor hydro project. My hydro grow room is upstairs in my house and I have 4 grow tents, each with a different fruit/vegetable growing inside including watermelons/cucumbers, banana plants, tomatoes, peppers, etc. I checked my dying plants a few weeks ago and noticed a webbing around my strawberry leaves. After Googling several different sites and inspecting the leaves, I came to the conclusion that I had spider mites... probably this entire time and probably what has killed several of my plants. I did not want to use insecticides and other harmful chemicals, so I turned to neem oil. I had a 1.5 liter spray bottle and mixed it with 2ml (I use a medicine dropper to measure). Shake well and starting from the top of the leaves, spray the tops/undersides of the leaves well, then work your way down. I clipped the brown leaves off. To prevent burning, I treated the leaves at night before lights out. Today, 4 days later, I see new leaves growing on my banana plants and they are not so quick to turn brown. Additionally, my strawberry plants look revitalized with a healthy green sheen on the leaves. I know this stuff is working well and I'm very glad that I bought it. For all you folks who are worried on whether or not this oil is organic, are you aware of what happens when you mix oil and water? It does not mix well. The extra ingredients help the neem oil stick to the leaves. If I had a choice to use something that is only 75% organic neem oil OR have dead crops, I choose the neem oil. I am very thankful for this product and 100% support and recommend it for indoor pest control.
Review: Versatile and Effective Organic Pest Control - As an avid gardener, I'm always seeking effective organic solutions, and Bonide's Neem Oil consistently delivers. This concentrated 16oz bottle goes a long way when mixed with water. It proves highly effective against a wide range of insect pests, fungal diseases, and mites on vegetables, fruits, ornamentals and more. The oil smothers pests and creates an anti-feedant environment. Application is easy with a hose-end sprayer. Plants show no signs of burn or phytotoxicity when used as directed. Unlike some harsh chemicals, Neem is relatively low-risk for beneficials like bees. An incredibly versatile and eco-friendly pest management tool for organic growers. Highly recommended!

## Questions & Answers

**Q: on the label it says "for organic gardening" , and this is 70% neem oil and 30% other ingredients. What are the other ingredients?**
A: Hydrophobic fluids need a stabilizer, you can’t have pure hydrophobic extract... look at any of the other providers that use hydrophobic extract of neem oil and it will be a 70%/30% mix! 

If you want 100% neem oil, the product won’t be an extract and the instructions will tell you that you have to add dish soap + only to mix up what can be used immediately

**Q: What percentage of neem oil does this have? 100% or 70%?**
A: Good question. I just got mine and checked. It has 70% and 30% other ingredients and I can't see what the 'other' ingredients are right now. But it does stare that it is for organic gardening. However, I will be looking for some that is a 100% neem oil in future. Thanks for the intelligent question. I wonderered why it mixes so easily with water. The good thing is it only takes 2 table spoons to the gallon and seems to be doing the job it states it will.

**Q: Does this kill japanese beetles**
A: You can also pull them off kill them and spread them back among the plants. From my observation they won't come back when there are dead buddies (or bodies...lol) anywhere around.

**Q: My bottle doesn't say how much to mix with water. 
Can you please help?**
A: Add 4 teaspoons to a bowl first. Then add 2 teaspoons of dish soap to the same bowl. Emulsify (mix) them together in the bowl thoroughly. Add this mixture to a gallon of water. Shaker well and spray the plants until they are drenched wet. Remember to cover each leaf on both sides thoroughly. Adjust the quantity of mixture as appropriate.

### ⭐⭐⭐⭐⭐ Works great,no irritating odors, very effective
*by J***A on May 26, 2024*

I love this stuff. Works extremely well, just apply it as directed and make sure you redo it. It’s a natural product, so it tends to wash away if it rains and needs reapplication over time. Keeps all the nasties away, but it obviously doesn’t affect your pollinators. I use this on my organic vegetable garden. No effect on the taste of anything (washes off easily). You’ll see the difference if you’re watching closely—no more eaten leaves. Check it out. It’s worth it.
