WHY :
Many insecticides break down quickly. They wash away with rain, or when irrigating, or the sunlight destroys them. You either have to spray all the time, or you have to spray something that's so stable that it stays around forever. That means the chemical builds up everywhere and eventually poisons everything, including you.
Neem oil breaks down very quickly, too. It is especially susceptible to UV light. But neem oil is also a systemic insecticide. That means you can pour it on the soil (not pure neem oil of course, you use a dilution or extract) and the plants absorb it. They take it up into their tissue, and it works from the inside. A leaf hopper may take a couple of bites, but that's it.
However, this does not work for all insect species. The neem ingredients accumulate in the tissues deeper inside the plant. The phloem, the outermost layer, contains hardly any. A tiny aphid feeds from the phloem, it can not penetrate deep enough to get a dose of neem. But any leaf hoppers, grass hoppers or similar chomping insects will be incapacitated quickly.
People eat neem leaves to cleanse the blood, stimulate the liver, and boost the immune system. So we certainly don't need to worry about a bit of neem inside our lettuce leaves. To me this is a much more attractive option than having poisonous foulicides build up in my garden.
