Organic insecticides are a prime need for those who are into organic farming. In organic farming, you depend on your farming methods to ensure that your plants do not have pests, but even when there are pests, you can learn to ignore some of them as long as they are not enough to cause damage to your plants. However, when you reach a stage whereby you need to get rid of your pests, you need to use organic insecticides to get rid of these pests.
Organic insecticides are thought to be environmentally sound, causing no harm to the earth, humans, or animals. They often consist of such things as fatty acids and plant oils. Natural pesticides act upon pests either through contact, or through absorption by the pests of these chemicals. The advantage of using organic pesticides is more of a reverse strategy, whereby you consider that artificial pesticides can use harmful chemicals (DDT anyone?), with a lot of residue left behind that affects other insects and pollutes through run-offs into rivers and streams.
However, you should keep in mind that using pesticides is part of an overall pest avoidance strategy that employs the usage of traps, and naturally occurring insects / other animals which counter the pests. This is also because artificial insecticides are more powerful than organic ones, and you need to compensate with a more comprehensive pest avoidance strategy. You need to ensure that you are following all these tactics before you start considering the use of pesticides (even organic pesticides). Further, just because an insecticide is organic does not mean that it is totally harmless; you should make sure that you are using the insecticide in the quantities and in the mechanism as directed. Also, be careful about the exact insecticide you are using.

If you are into organic farming (or if you are following organic principles for your kitchen garden), then it is very important for you to know all about organic insecticides. One of the problems quote in traditional ways of farming is the use of chemical / synthetic pesticides that leave residues that make their way into animals and humans, and also end up polluting the soil and water. So, what is an organic insecticide ? It is a substance made from natural ingredients that is used for repelling insects and pests; you still need to repel pests and insects even if you go organic.
Organic insecticides are also specialized, in the sense that certain insecticides work on different insects / pests, and you need to do the necessary research to ensure that you have identified the pest you need to get rid of, and what insecticide you need to use. Before making that decision though, ensure that you have actually reviewed that you do have an insecticide or pest problem. Just because an insect is eating away the leaves from your plant does not mean that the plant or the produce is getting harmed (plants can take a loss of upto 25-33% of their leaf cover before their growth is harmed).
Further, ensure that you have also checked out that there are no natural predators that you can use; for example, certain bugs eat insects or pests as a part of nature, and using that solution might work out better. However once you have decided that you have a pest problem that cannot be solved by any other means, then you need to use an organic insecticide.

The Organic Gardener’s Handbook of Natural Insect and Disease Control: A Complete Problem-Solving Guide to Keeping Your Garden and Yard Healthy Without Chemicals

Soil preparation is critical if you are going in for organic farming. You do not have the liberty of adding a load of chemical fertilizers later if you find some deficiencies in the soil; and the motto for organic farming remains, “do adequate preparation rather than react later”.
Making sure that the soil is healthy is an important first step in the preparation for organic farming. If the soil used for organic farming was earlier used for commercial farming, then you need to spend time to ensure that the presense of chemical fertilizers and pesticides have been removed from the soil (how to do this is a separate post), the duration for which you need to have kept such soil clean before using it for organic farming depends on the organic gardening certification in your country or state, and you should check those regulations.
The steps that you should take in order to get your soil ready are:
- Make sure that there are no weeds, stones, or pieces of other debris in the soil, and that it is ready for next steps
- Do a soil analysis. You can get a proper soil analysis done, or you can look at the rough ways of estimating the quality and breakup of your soil. Soil should have 3 main components (sand – 40%, silt 40%, and clay 20%). The soil should be one that you can compress with your hand, and it forms a solid mass that breaks when you poke it. If it either is unable to form a solid mass, or does not crumble when you apply effort, then the soil either has too much sand, or too much clay. An imbalance can result in the soil not being optimum, with imapct on water logging, or the ability of soil to let plants grow in it.
- You can also take a sample of your soil, put it in a glass beaker or jug of water, and then shake, and then let the soil settle down. The settling inside the glass leaves you with 3 different layers, of sand, silt and clay (with clay on top). The levels of each will slowly start giving you an idea of what is missing, and then you can add more of the missing element to get a better mixture. of course, if you are not able to get a correct mixture, go to the store and ask them for the amount of soil you require (make sure that you specify that you are going to grow organically)
- Look to see how you can encourage the growth of healthy stuff such as microbes, earthworms, etc. They do a lot to make your soil better.
- Read up about the various fertilizers you can add to your soil to make up for deficiencies. This would mean that you need to find out what your soil is missing, and requires some amount of knowledge (or if you don’t have knowledge, either learn, or get somebody who can advise). Be sure that adding some good compost is typically helpful for the soil.
- Learn about crop rotation, so that you plan ahead for the crops you are going to put in the soil, and learn about which plants add which element, and remove which nutrient from the soil. Doing this is essential if you want to make sure that you soil is good in terms of nutrients, not only now, but for the future.
- Soil is improved when you add organic matter to the soil. This means that you should items such as compost, and even some more strange items such as hair (for nitrogen), grass clippings, purchased organic fertilizer, peat moss
- If you can, enable poultry to have free access to your soil. Hens do a fair amount of the manual hard work required, such as removing weeds, adding manure, and undertaking tilling of the soil.

Now you are onto the organic farming bandwagon, either convinced by the health and environmental benefits, or convinced by the economics of it (or a combination of both). Now you want to know what are some of the fertilizers you can use as a part of organic farming ? After all, it is not possible any more to use the chemical fertilizers since these are not permitted as a part of organic farming, and go against the principles of using organic additives.

Compost: Compost is an excellent organic fertilizer that provides a rich source of nutrients to the soil. Making compost is not very complicated, the only thing it takes is some attention and time required for converting the organic waste to compost (months usually). It also helps in utilizing waste such as leaves, kitchen waste (except for meat), etc.

Nitrogen: Nitrogen in the soil is provided through the system of plant rotation, where nitrogen enhancing plants (that provide legumes) such as Alfalfa (as another example, potatoes should be grown on soil where sweet corn has been grown, since sweet corn adds to the soil what potato needs).

Livestock manure: Livestock manure is a natural method of adding nutrients into the soil and making it richer, a practice that has been followed since the beginning of farming. It is only in recent times that fertilizers started getting used; however, getting livestock manure as fertilizer for organic farming works fairly well.

Seaweed and kelp: This is an additive that is often ignored, but should be used. For those near sea coasts, this is plentiful, and provides nutrients, including materials that are not found elsewhere.

Compost tea: This additive sounds a bit strange, but is actually rich runoff during the composting process. Make sure that you have provisions to collect it, and use it as another fertilizer. It works great with potted plants.

Naturally occurring minerals such as mine rock phosphate, sulfate of potash and limestone are also considered organic fertilizers.

Slurry: A mixture of animal waste and water is used as organic fertilizer

Vermicompost: This is a mixture of decomposing vegetable / food waste, bedding materials, and pure vermicast produced during the course of normal vermiculture operations. This mixture contains water-soluble nutrients and bacteria, and makes for rich fertilizer, ideal for organic usage.

Guano: It is the excrement (feces and urine) of seabirds, bats, and seals. Soil that is deficient in organic matter can be made more productive by addition of this manure. Guano is rich in phosphorus and is an effective phosphorus fertilizer.

Blood meal: Blood meal is dried, powdered blood used as a high-nitrogen fertilizer. It is one of the highest non-synthetic sources of nitrogen and if over-applied it can burn plants with excessive ammonia. Blood meal is completely soluble and can be mixed with water to be used as a liquid fertilizer.

Epsom Salts: Commonly used to provide magnesium and sulfur to the soil. Promotes bushier growth and more flowers.
