Since I'm in Oklahoma, I go to the Oklahoma gardening forum on Garden Web and a lady(okiedawn) on this forum provides a tremendous amount of information on all types of gardening. It's fun to read her posts and if you live in Oklahoma or close by, she might be able help with some of your garden problems.
Here are two of her posts on Neem Oil and dried molasses
Neem Oil

Mick,
I have mixed feelings about the use of Neem, but it is one of the more effective organic products available. It is OMRI-approved although I believe their guidelines define it as a tool in Integrated Pest Management programs which is to be used only after milder methods or rememdies have been tried without success. However, it can burn plant foliage if applied at temperatures above 90 degrees, so keep that in mind. And, in fact, here in our climate, I think Neem and some other foliar products (including insecticidal soaps and superfine horticultural oils) can burn at significantly lower temperatures--more like 80 degrees than 90 degrees.
Neem is derived from the Neem tree, which is native to Burma and India and grows in many tropical areas. The Neem tree, by the way, is related to Chinaberry and Mahoghany. Extracts of the neem leaves and/or seeds are used as a natural pesticide. Some extracts from neem bark are used in some products as well.
Neem is is antibacterial, a fungicide and a pesticide. However, it is NOT a systemic pesticide if used as a foliar spray. It IS a long-lasting systemic insecticide on pests located in soil if used as a soil drench.

In a different thread, Jill mentioned hearing an "old-timer" who had converted from chemical methods of gardening to organic gardening talking about using dried molasses. And, it occurred to me, that I probably seldom if ever mention molasses, which is an important soil restorative often used by organic gardeners. So, I thought I'd discuss it a little here.
WHAT ORGANIC GARDENING REALLY IS:
A lot of people call themselves organic gardeners because they don't use pesticides or fertilizers of chemical origin, and only use those of organic origin. That is a good start, but organic gardening is so much more.
Organic gardeners understand that EVERYTHING starts with the soil. Thus, they do many, many things to maintain healthy soil. This includes adding organic materials like compost, rock and mineral powders (like soft rock phosphate, greensand and lava sand), etc. It also includes doing whatever you can to encourage healthy soil that is ALIVE. Soil is not a dead, inert material (well, it can be, if it has been heavily farmed chemically). Good soil is alive and teeming with many, many microorganisms that contribute greatly to soil health. These microorganisms include but are not limited to bacteria (there's good bacteria, you know), fungi, algae, nematodes (there's good nematodes too), protozoa, and actinomycetes If these microorganisms are missing from your soil, your soil is not healthy enough.
