The use of pesticides is essential, but we can reduce the amount of pesticides by improving the application of pesticides to achieve the full use of pesticides and reduce pesticide pollution. The following technologies can significantly reduce the amount of pesticides, can save 50% to 95% of pesticides, and can greatly reduce or substantially eliminate the possibility of pesticide spraying onto non-target plants.
1. The recirculating spray technology redesigns the conventional spray equipment. A drug recovery device is installed on the opposite side of the spray component, and the liquid medicine on the target plant that has not been deposited is collected and then pumped back to the liquid tank for recycling. Effective utilization of pesticides.
2. Pelletizing and applying technology For the water-soluble agent used in paddy fields, the pelletizing application technique can be adopted. The pellet can be evenly spread in the farmland, the work efficiency is increased by a factor of ten, and there is no pesticide drift and no pollution. Adjacent to the crop.
3. Low-volume spray technology means that the application amount per unit area is constant, and the pesticide stock solution is slightly diluted, and the water consumption is equivalent to 1/5 to 1/10 of the conventional spray technique. This technology improves work efficiency and is widely used in greenhouses and mountains.
4. Electrostatic spray technology The high-pressure electrostatic generator is used to spray the droplets electrically, and the deposition amount of the liquid droplets on the surface of the blade is significantly increased, which can increase the effective utilization rate of pesticides to 90%.
5. The medicine roller application technology is mainly used for the internal absorption of the herbicide, and the liquid medicine is exuded from the surface of the medicine roller through the medicine roller (a type of plaster overflow made of a foam material capable of absorbing the liquid medicine), and only needs to be contacted with the mist. The leaves on the top of the grass will work. This method can almost completely apply the agent to the surface of the target plant without causing the liquid to spill and drip.
6. Application of Computer Technology The computer control system has been used in the United States for orchard sprayers. The system determines the shape of the fruit tree by ultrasonic sensors. The computer control system automatically adjusts the pesticide spray characteristics according to the shape of the fruit tree. This technology greatly improves the effective utilization of pesticides and represents the direction of pesticide use technology.
