The pests I have has eaten off the top of my green beans plants (young) twice. I bought some neem oil and want to use it, but don't have any leaves to use it on. Every time they get a leaf it takes one night and it's gone. So they don't have a chance to get big so I can spray. Any suggestions? Thanks

What if the gnats are so in the soil and not the leaves? Can you pour or spray the soil?

Gosh, I have different recipe I got from Neem bottle was 2 tablespoons oil, 4 cups of water and teaspoon of dawn clear blue dish soap and shake very well before each spray. It’s taken three days but papayas look like they’re already ruined, but there is much less white fly. Why don’t you give measurements for the main different types of sprayers out there and tell us which is a better sprayer because my one liter just broke.

Don't trust indians, that's probably 90% vegetable oil and 10 % neem. No way you can extract that much of oil from neem seeds i know it very well.

I tried experimenting with neem oil. I placed some oil drops in an ant infrsted area in my bathroom. The ants like it nd keeps drinking it. After a few hours I gave up and wiped the oil away. I don't see the ants dying.

There are neem brands that are "fake" and ineffective. Learned that the hard way

Very helpful video. From my own experience I wouldnn't use it to prevent or combat fungi ( botrytis budrot or powdery mildew). It does help against that sure, but so does a hydrogen peroxide solution (foliar), if you care about the taste and smell of your lettuce😂. You can also mix it with a little bit of dishwash (1 tsp/litre soap) together with the Neem oil (shake it until you spray bubbelly neem oil water), it then becomes a contact killer. If you have spidermites for example. Bubble them up with soap and neem. Make sure to get all the surfaces inside. Spray upwards. If working on a large scale you can use the oil from the "roasted" bark of the neem tree. It is 10 times cheaper, but cold pressed is better if you can afford it. Don't apply neem to things you ingest about 4-6 weeks before harvest.

Can someone please help me?
I want to make the stronger treatment solution. Where do I keep the extra solution until I can use it all? (The sprayer in the link only holds 34 oz. 🙂) Also, Is this okay to store in a hot climate in a car garage, or will it degrade? Perhaps I need to store it in a safe place in my house?

Thank you very much for your help!! 🙂

I've been using the neem oil for weeks and I almost think all the issues are getting worse. Am I crazy? I actually developed powdery mildew after using the neem oil. I also have more damage to my plants, from the neem, but also from pests. I'm so confused.

Neem is really only useful as a smothering agent once it's dried up it's gone

If the pest you're trying to get rid of is grasshoppers, don't bother buying this. I bought the 32oz bottle of the AINA Neem (about $50 with shipping!!), mixed it per the instructions on the bottle, and sprayed everything. It had no effect. So I increased the ratio of Neem. Still no effect. In fact, after spraying, the grasshoppers mowed some of my plants to the ground.
Don't waste your money on this to control grasshoppers.
