Technical analysis of plant protection

A biological control method.

Elimination of the use of biological pest predators approach. Such as: ladybug, Trichogramma

2 Physical Control Act

Use, plant protection machinery, control, for example: agricultural sprayers tractor spraying machine, spraying machine hanging

⑴ spray - nozzle by a high pressure pump and the liquid is atomized into a method 100 to 300 microns. There are manual and motorized divided.

⑵ Mist France - the use of high-speed airflow generated by the fan will be further broken coarse droplets atomized into droplets 75 to 100 microns, electric sprayer and blown into the distance. Is characterized by tiny droplets released into the atmosphere is good, evenly distributed, covering a large area, can greatly improve productivity and spray concentration.

⑶ ultra low volume method - the use of high-speed rotation of the toothed disc thrown the liquid form 15 to 75 micron droplet, do not add any dilution water, so called ultra low volume farm sprayers.

⑷ smoke method - using high-temperature air to preheat thermal fission occurs after smoke, electric sprayer to form a ~ 50 microns of smoke, and then with the high-speed air blown into the distance.
