Fatty drugs cleverly combined with five different mixtures have shown excellent results in pest control and crop yield improvement. Here are five effective combinations that farmers can use:
1. **Urea mixed with detergent**: Mix 0.5 to 0.75 kg of urea with 0.125 kg of washing powder and 50 to 60 kg of water. Spray the solution on the leaves of crops such as grains, cotton, vegetables, and fruit trees. This mixture effectively controls locusts, spider mites, and other pests. Spraying every 7 to 8 days, or even up to three times, can achieve a control rate of over 90%, while also boosting crop yields by approximately 10%.
2. **Dimethoate mixed with vinegar solution**: Combine 40% dimethoate with vinegar and water in a ratio of 1:1:1500. Spray 60 kg per acre on foliage of crops like grains, cotton, vegetables, fruit trees, and tobacco. This mixture is highly effective against locusts, spider mites, thrips, and leaf miners. It reduces pesticide use by 30% compared to using dimethoate alone and increases its effectiveness by 20 to 30%. The vinegar helps soften pest bodies, improving insecticide penetration, and also provides nutrients that support plant growth.
3. **Urea and dimethoate mixture**: Use 50 ml of 40% dimethoate per acre, mixed with 0.5 kg of urea and 60 kg of clear water. Spray this solution on leaves of crops like grains, cotton, vegetables, and fruit trees. It effectively controls aphids, thrips, and leaf miners, leading to a noticeable increase in production. However, since dimethoate has a short residual period (about 5 to 6 days), it's recommended to spray every 5 days for best results.
4. **Trichlorfon mixed with ash**: Soak 10 kg of sifted hay in 50 kg of fresh water for 24 hours, then filter the liquid. Add 0.025 kg of 85% trichlorfon to the filtrate and spray on leaves of grain, cotton, vegetables, and fruit trees every 7 to 8 days. This mixture effectively controls aphids, red spider mites, cabbage caterpillars, armyworms, rice planthoppers, and leafhoppers. It also improves crop yield significantly.
5. **Nitrogen-phosphorus compound fertilizer mixed with omethoate**: Dissolve diammonium phosphate in water to make a 1% concentration solution. Use 50 to 60 kg of this solution per acre, then add 20 to 30 ml of 40% omethoate EC. Spray the mixture on leaves every 7 days, or up to three times if needed. This combination is highly effective against spider mites, aphids, thrips, and cotton bollworms, achieving a control rate of over 90%, and increases crop yields by about 10% across various crops.
These methods not only help in managing pests but also promote healthier plant growth and better harvests, making them valuable tools for sustainable farming.
