Review (5/5): 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.
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).
