No organic products can be used to control weeds, and this is one of the biggest problems in organic farming.
Some of the Pest control products used in organic lawn care are: liquid dish soap(NOT detergent), ammonia & plain instant tea for weed control; liquid dish soap(NOT detergent), ammonia & beer for thatch control; Greelight (link-http://www.greenlightco.com/organic_lawn_care.htm) manufactures organic lawn care products which include many pest control products.
Use it as a mulch over the top of the soil to suppress weeds.
Products whose active ingredients are made from plant parts, bacteria, or approved soaps and oils are what organic farmers and gardeners use in place of the artificial, chemical, synthetic controls of conventional production. Typically, organic farming and gardening products are made from plants. These are known as botanical pesticides. For example, pyrethrin is made from pyrethrum daisies. As another example, a spray is made from the seeds of the neem tree.Other organic farming and gardening products may be made from bacteria. These are known as microbial pesticides. Examples are 'Bacillus thuringiensis', and 'Milky spore'.Still other organic farming and gardening products may be made with oils. One example is the refined petroleum in horticultural oil.Yet other organic farming and gardening products may be made with approved soap. These are known as insecticidal soaps.
IT is not clear what you are asking about but if they are organic then they should all comply with the Soil Association rules for products sold or labels as "organic".
Organic farming prohibits the use of synthetic chemicals to control pests, except in extreme cases. Instead, natural predators and intercropping are used to control pests and special machinery and fire control handle weeds. Organic farming methods use natural fertilizers, like compost and animal manure, that recycles the nitrogen already in the soil rather than adding more, which reduces both pollution and N2O emission.

There are some organic products that you can get coupons for. I have used coupons for organic cereal and peanut butter, but I have seen coupons for other products..
In the US, organic farming is typically more expensive than common non-organic methods, primarily because of the cost of additional hand labor. There are also additional costs associated with the organic control of weeds, insects, and diseases. Organic farming can be cheaper to get started on, because a farmer doesn't need the same kind of equipment. Simple, "old-fashioned" equipment can be used for some crops.
There are organic pesticides, diatamacheous earth for one.
Organic farming can be used for any crop that can be grown in the future. Since no synthetic fertilizers or pesticides are used in organic farming, if the soil is not suitable it would need to have organic matter and/or compost added, as well as other organic enhancements possibly. Also, organic methods of controlling insects and weeds would need to be used, but growing organically is not limited to any certain area.
someimes, not always
Herbicides to control weeds, sometimes fungicides to control certain kinds of infections, and rarely insecticides to control harmful insects.
