I wish manure was banned as a legal material to spread. If not officially banned, at least ban it in the minds of the participants in this forum. The ONLY valid use for manure that I see is as an ingredient for compost. And after it is composted it must pass at least a smell test to see if it is still manure. Manure stinks and will kill your chances of gaining clientèle. Here are some organic pesticides from the Green Light company. 1. Bioganic® Organic Insect Control Concentrate 2. Fire Ant Control with Conserve® 3. Cedarcide® Insect Repellent Bioganic is a mix of three oils. It is non selective so I don't like it. Conserve (TM) is spinosad, a nerve agent, that kills insects and decomposes very easily. It is created by actinomycetes, a specialized bacterium that is also an indicator in finished compost. Cedarcide is ground up cedar chips from juniper trees in East Texas. I have no opinion on that one. But I really like the beneficial nematodes under the name Guardian/Lawn Patrol at this website. These guys work on 250 different pests without hurting the beneficials. These things are raised on pest species as hosts and carry a disease that is very deadly to them. It is a good idea to spray these guys a month before you need them. I sprayed today for next summer's fleas. I used them last year and never had one flea on my dog. This is a first for me. I used to give my dogs the spot treatments and don't have to now. And for reference to adjust seasonality from my area to yours, it is early spring down here. Some trees are budded out and blooming, crickets are chirping, grass is starting to grow on the organic lawns, birds chirping, etc. - all that spring stuff is going on. Wild flowers are just around the corner.
