  • How to make organic pesticides for plants?

    Want to know more about organic pesticides used for plants? Searching for detailed information regarding making emulsions and pesticides naturally? No worries, find advice from experts on this page and decide forward plan of action.

    I am very much interested in rooftop gardening. I grow some plants for vegetables and flowers. But I am finding some of the plants being affected with pests. Whenever I see any visible insects, I physically remove them. But sometimes it is becoming difficult to remove them physically. To control pests, I used neem oil, soap solution, etc., but it is not giving fruitful results. I have heard about some emulsions are being used as natural pesticides. What are these emulsions and how to make other organic pesticides for plants naturally?

  • It is very annoying for a gardener to see pests sucking their plants. A plant lover hates watching the flowers, leaves and the plant being suck by pests even after taking utmost care of them every day. Some of organic, natural and inexpensive methods for making pesticides are given below:

    1. Neem Spray - In a spray bottle, add some neem oil, little quantity of liquid soap and some warm water and stir slowly and use immediately. It is said to be effective for about 22 days and its bitter taste and strong odour keeps the bugs away.

    2. Onion and Garlic Spray - Take about a bulb of garlic and one medium-sized onion and grind it together. Now take 1 litre of water and mix the grinder ingredient and keep it for some time. After some time, add a teaspoon of pepper and a little liquid soap and mix all together well. Your organic pesticide is ready. Just spray it on the plant to keep pest away.

    3. Tobacco Spray - In a gallon(3.75 Litre) of water add 1 cup of dried, crushed tobacco leaves and keep it soaked for about 2-3 hours. The more you soak, the stronger it gets. To the content add one teaspoon of dishwashing liquid soap and a pinch of pepper powder and mix well. Now strain it and fill in the spray bottle.

    4. Salt Spray - In a gallon(3.75 Litre) of water, mix 2 tablespoons of salt and mix well. Now pour it in a spray bottle and use it.

    5. Orange Peel Spray - In a liter of water put two cups of orange peels or orange oil and boil it. Once it boils, strain it and let it cool. Now to it add few drops of neem oil and little liquid soap and mix all together well. Now pour it in a spray bottle and your orange peel spray is ready to use.

    Some of the points to note before using pesticides on the plant:
    - Do not use a dishwashing liquid soap that contains bleach for your preparation.
    - Use the pesticide on a small portion of the plant before spraying it all over to test it for any sensitivity.
    - Do spray on the underside of leaves as many pests and insects hide underneath the leaves.
    - For better results, spray in late afternoon or evening or when there is no wind. It will help to target the plant properly.
    - The organic or natural pesticides work slowly on plants and for better results, be patient and use them regularly.

  • Organic pesticides are pesticides derived from natural ingredients. These will be obtained from botanical and mineral sources. They are safer than synthetic pesticides. These will protect the plants and not harmful to living beings. But synthetic pesticides will have some negative and side effects on human beings. These synthetic pesticides will affect the birds and animals also. That is why it is always better to use natural organic pesticides.

    The following are the types of natural pesticides.

    1. Biochemical: They will decrease the mating behaviour of insects and thus see that the insects will not propagate beyond control.

    2. Microbial: These pesticides will bring disease to insects and may also make a toxin. They will also minimise the reproduction capacity of insects.

    3. Botanical: These are derived from plants and effectively control flying insects

    4. Mineral: These are the materials obtained from minerals from the earth. Sulfur, limestone and other minerals can be classified as Mineral-based pesticides.

    Homemade pesticides.

    The best way of controlling the problems of plants to grow different types of plants which will support the other plant in combating with these insects. Growing a neem plant of bonsai type in the rooftop garden will help to control the ill effects on other plants.

    The following are some good organic pesticides.

    1. Garlic is one good naturally occurring pesticides. They will fight beetles. Feverfew and tansy are also good insect repellents.

    2. ladybugs and wasps are good to control the increase of population of unwanted insects. It is better if we can allow them to grow.

    3. Vegetable oils are good pesticides. But the concentration is very important. They should be used after mixing with enough quantity of water and organic dish soap. This is good for small sucking insects.

    4. Sticky papers can be used as traps to control insects going on to the plants.

    The following recipes can be made and tried.

    1. one garlic piece and a tablespoon dish soap without any bleaching property are to be mixed in two tablespoons of vegetable oil and then added two cups water. Keep the mix overnight and then filter. Fill it in a spray bottle and spray.

  • Many people have home garden and some are even having small set up in the flats where they are managing it in the balconies. Once the plants and saplings are ready to flower then they will require two times watering and some external nutrition in terms of manures. At the same time it also happens that some insects or weeds or fungus can accumulate on the plants and harm it. We can use some home remedies for killing these weeds or insects but one single remedy can not be sufficient to kill all types of the harmful insects etc. So, sometimes composite solution might be required in this situation. Some of the home remedies are -

    1. . Neem oil - Neem oil is a very good organic remedy for getting rid of the many varieties of the insects harming the vegetation. To use it a spray will be required to be made by adding 2 parts of Neem oil to 1 part mild liquid soap and 20-25 parts of water. Use this spray on plants to get the plants cured of insect infestation.

    2. Diatomaceous earth - This is a very good material for poisoning the insects and putting it in the flower pot will help immensely. This will be available in local gardening shop.

    3. Garlic - It is more of a repellent than the insecticide but it works in many cases and insects leave the plant. Many are killed with its pungent smell. To make the garlic spray, 2 numbers of whole garlics are to be taken and to be peeled out and now we have to make a paste of it by grinding and add tomatoes and vegetable oil. Dilute it with water and use as spray.

    4. Tomato leaves - Take 3 cups of tomato leaves and mix with 3 cups of water. Keep this overnight and then rinse and make a paste. Filter it and use the liquid for killing the insects and infested parts of the plant..

    5. Soap spray - It is also a common home remedy. We have to mix 1 tablespoon of mild soap in 2 cups of water and mix well and use this spray directly on the plants to kill a variety of insects.
