    Hi everyone. I was just wondering if someone could point me in the right direction. I am trying to find a website to purchase pesticide free fert, weed controls, etc... Organic materials.. And hopefully - maybe perhaps some one has puchased from before, or know that the products are good. I imagine the more you buy, the cheaper the product?? So possibly a wholesale supplier? Anything would be appreciated greatly..Thanks!

    purchase it right in local farm store mill.
    corn meal works excellent cost about $207 / ton
    vs. corn gluten meal for about $20 / 50# bag

    Corn Gluten Meal for Crabgrass Control
    The idea of using corn gluten meal for weed control burst on the scene in the early 1990's after Dr. Nick Christians
    at Iowa State accidentally discovered its herbicidal properties while he was testing it for suppression of turf
    diseases. After several years of efficacy studies and product development, corn gluten meal has gained national
    attention as being the first effective "organic" herbicide. Corn gluten meal is not a registered pesticide because the
    U.S. EPA has granted an exemption for corn gluten meal as an herbicide.
    Corn gluten meal is a product of the wet milling process. It is a pre-emergent herbicide which inhibits root
    formation during germination. It is currently labeled for control of crabgrass, barnyardgrass, foxtails (Setaria spp.),
    dandelion, lambsquarters, pigweed, purslane and smartweed. Data suggest it has at least some activity on an even
    wider variety of plants. It is safe to use on established turf. Do not use corn gluten meal in an area in which you are
    trying to establish turfgrass.
    Research shows 50-60 percent control can be achieved in the first year when applied at 20 lbs. Per 1000 ft. Studies
    suggest that control is improved in successive years and as use rates increase. Currently it is sold as a dry product
    under various trade names, including Dynaweed, Safe 'N Simple, Earth Friendly, W.O.W.!, Corn Gluten Meal
    Herbicide and Propac. It is sold for the homeowner market in retail stores as Concern-Weed Prevention Plus. Until
    recently it was only offered in powder form. Now a granular form is available which can be more easily applied
    with Vikon spreaders, rotary and drop spreaders. Application rates vary from 12 to 20 lbs. per 1000 feet, once in
    early to mid-spring and another in early to mid-August. Since the corn gluten meal is about 10 percent nitrogen,
    this catches two flushes of crabgrass and spreads out the nitrogen effect. Two applications at 12 lbs/1000 ft. Will
    provide nearly 2.5 lb. N/1000 ft per year. The nitrogen is in a slow release form so there is little to no potential for
    foliar burn. Bulk orders cost about $950/ton; 50 lb. Bags run between $25 and $30. This is the same corn gluten
    meal sold at feed mills for animal feed; however, it is pelletized for easier and more uniform application.
    Portions of at least two proteins in the corn gluten meal, called peptides, are the active ingredients in corn gluten
    meal. Laboratory studies show the peptides themselves to be significantly more effective at preventing weed
    germination than the corn gluten meal itself. Unfortunately the peptides do not persist in the soil when used as a
    spray long enough for effective control. Current research is aimed at isolating and packaging these peptides to
    produce a sprayable product.

    Not sure if this is exactly what you're looking for, but North Country Organics isn't too far from you.

    It would be best to experiment with it before investing heavily into it... CGM is as good as any fertilizer, so that part of your claim as an LCO should be safe... but as a pre-m it is a waste... so you really notice a difference if only 100 CG plants invaded your yard, instead of 200???
    Will your clients believe that their CG problem may have been 40-50% worse and you promise to do better next year???
    I don't have any lawns that require pre-m, because they have been managed to the point of maturity in which CG doesn't find habitat for germination... that is your true organic way... natural,,, not artificially dependant...

    Those prices are ten years old. It's much higher now.

    To get 1 pound of N/k from Milorganite I pay about $2.66 ...

    Go to your local agricultural co-op(should be one in a county near you) and see how much a 50 pound bag costs, then compare cost of pounds of N...

    It's about $33.00/50 lb bag when sold by the pallet.

    When used as a pre-emergent it should be applied at 20lbs./k.
    Comparing the amount of N with Milroganite is apples to oranges as Milorganiite has no herbicidal properties.

    That being said, do not compare the effectiveness of corn meal with chemical herbicides. A successful organic lawn care program involves more than just switching products.
