Kinds of Plant Insecticide

Nowadays, the development of technology using a chemical has poisoned the environment around us. Agricultural use of chemical fertilizers and pesticides has indirectly damage the environment. to reduce exposure to residues of synthetic chemicals on the environment, we can use some of the following types of biological pesticides. 

• Garlic (Alium sativum) 

100 g garlic, 0.5 l water, 10 g of soap, two tablespoons of mineral oil (baby oil). Garlic grated / crushed and mixed with mineral oil, leave for 24 hours. Garlic mixed soap dissolved in mineral oil evenly and then filtered with a soft cloth. Its use for every one part of the mixture was dissolved into 20 parts water. These materials are effective for some types of nuisance insects.Nonetheless need also tested with different concentration levels to determine the most effective concentration. 

• Amethyst (Datura stramonium) 

1 kg of fresh leaf amethyst bud, flower and seed, crushed, then soaked in 10 l of water and liquid soap. This marinade is left for at least 3-5 hours. Then filtered with a cloth and sprayed.Recommended for liquid laundry detergent added as a wetting agent (surfactant). 

• Mindi (Melia azedarach) 

150 g fresh leaf Mindi blender in 200 ml of water, then mixed into 800 ml of water and left overnight. This solution is filtered with a cloth can then be directly sprayed. Mindi can also use fresh beans. 0.25 kg of finely ground seeds Mindi then mixed with one liter of water, then filtered and used as much as 5-7 liters of solution. Also added in a solution of two teaspoons of liquid soap. This extract can ward off grasshoppers. 

• Neem (Azedarachta indica) 

Neem seed oil has a great capability in terms of killing, drive away, and poison the insects or other nuisance organisms such as nematode and fungi. Seed oil neem seed extract can be obtained by using water. Seed that has been collected, cleaned of flesh, then dried to prevent mildew during storage. At the time of use, seeds removed from the skin, 25-50 g of finely ground seeds and soaked in 1 l water, was added also with two teaspoons of soap. The results showed that 500 g of dry seeds were soaked in 400 l of water can be used for an area of 4000 m  and able to last for two weeks if not exposed to heavy rain. 

• Papaya (Carica papaya) 

1 kg of fresh papaya leaves chopped fine and soaked into 10 liters of water and then added 2 tablespoons of oil and liquid soap. Left overnight, filtered and then sprayed with a soft cloth. 

• Tobacco (Nicotiana tabacum) 

1 kg of tobacco leaf (leaf remnants) finely chopped and soaked in 15 liters of water, plus 2 teaspoons of liquid soap and then left overnight. After being refined can be used for sprayed. Or they can be every 200 g of tobacco leaves in a blender and diluted to 3 l of water. 

In addition to the above crops are still many plants in Indonesia that could be used as biological pesticides, such as yam bean, leaf sirsat, poison yam tubers, etc., that will someday be uploaded to the web author of this beloved. So wait and see the continued development of this web from day to day.
