Very, very effective
This product is very effective and I am very pleased I purchased it.  Last year I had the worst insect & fungal damage in my garden I had ever seen, especially with potatoes and eggplants.  I have always used foliar sprays with seaweed/garlic/pepper and had very good success; but last year was different.  I tried using a Spinosad product combined with prior practices, but did not see good results.  After researching issue for spring planting, I decided upon this product.  I sprayed all of my potato beds and could not believe how effective it was.  I had seen Colorado potato beetles and larvae and the day after I sprayed I could not find a single survivor.  On one plant alone I counted 15 dead beetles - pic of larvae/young beetles attached.  And the plants looked so much better.  Very impressed.  Plus neem is also a good fungicide and miticide.<br /><br />I saw a YouTube video where someone pointed out that neem oil label should state that it contains Azadirachta indica because this is the active ingredient.  I had a 10  year old bottle of neem (which I had assumed had lost its efficacy) and noticed that it did not state that it contained that.  (Now, I don't know if that is actually true or not but the fact that this product explicitly touts the high levels of this ingredient was a large factor in my purchase).
