Human and animal urine can prevent disease and pest control
In agriculture, using organic waste as a natural pesticide is an effective and eco-friendly approach. Here are several methods that have been proven to work well in pest control while also providing nutrients to the crops.
First, rabbit manure can be used to control pests such as the tiger flea. Rabbit droppings are rich in nitrogen, phosphorus, and potassium, making them an excellent natural fertilizer. They also act as a potent pesticide with a control rate of up to 90%. To prepare the solution, collect one container of rabbit feces and mix it with 8–10 times its volume in water. Cover the container and let it ferment for about 15 days. After that, dilute the liquid further and pour it directly around the roots of the plants, about 8–10 cm deep. This method not only nourishes the soil but also effectively manages pests.
Second, fresh cow urine has been successfully used to control aphids. For a hectare of vegetable field, use 450 kg of fresh cow urine mixed with 450–600 kg of water and spray it during sunny hours. The effectiveness in controlling aphids is over 95%. Another method involves using tea seed cake (30–35 kg per hectare), crushed into small pieces and soaked in 370 kg of water for 12 hours. Then add 25–30 kg of fresh buffalo urine and spray it during the morning hours (8–10 am). Applying this mixture 2–3 times helps control rice blast disease with great success.
Third, sheep manure is effective in managing various pests. For example, 450 kg of sheep manure filtrate per hectare can control melon powdery mildew with an efficacy of 80–90%. During the early stage of wheat earing, sheep urine can be used to manage grasshoppers, with 250–300 kg of sheep manure filtrate applied per hectare, achieving over 80% insecticidal effect. Additionally, spraying 300 kg of sheep manure filtrate per hectare can control high worm infestations with more than 95% effectiveness.
Fourth, a combination of rabbit and sheep manure can be used to manage pests like spider mites. Mix the two types of manure in a ratio of 1:4 to 1:6 with water and store them in a cement tank or septic system for 15–20 days. When ready, dilute the rabbit manure solution with 50% water and apply it around the roots of vegetables to prevent underground pests like ground beetles and earthworms. Using 300–450 kg of the mixture per hectare can control spider mites in cotton fields with up to 90% effectiveness.
Lastly, human urine can be used to treat maggot infestations. Apply 450 kg of fresh human urine mixed with 450–600 kg of water, and spray it after 9 o’clock on sunny days. This method controls mites with over 95% effectiveness. However, it’s important to note that undiluted human urine should not be poured directly onto crops, as it may cause plant damage.
These traditional techniques not only reduce the need for chemical pesticides but also promote sustainable farming practices. By utilizing naturally available resources, farmers can protect their crops in an environmentally friendly way.
