Advantages of organic pesticide -


Use of organic pesticides is helpful in maintaining environmental and ecological balance.

Biological insecticide kills only targeted pests and diseases, whereas chemical insecticide kills friendly insects as well.

• Due to the use of chemical insecticides, the resistance of insects is developing, due to which the number of insects is increasing, which is becoming a threat to crop production in future.

• There is no change in the biological nature of insects by the use of organic insecticides.

• Being based on flora and fauna, organic pesticides get decomposed in the soil in about 1 month and no part of it remains.

Note -


👉 If you are unable to get cow urine, you can use waste decomposer solution in place of cow urine.

👉Keep in mind that use insecticides only on one month old crop.
You can buy it online also.
