Weeding process of chemical fogger

With the development of science and technology, complex and spending a lot labor agriculture work is more simplistic. Spring, large areas of wheat in addition to pest control, pesticide sprayers need to complete. Catcher in the work of weeding and ultimately chemical fogger application, in order to achieve better herbicidal effects, in addition to the applicable choice of herbicide, proper weed spraying methods and precautions of using chemical fogger are also a very important part.
First, adjust the instrument is the first step in chemical fogger weeding .
1. Medical Device Inspection, add water check kits and spray all joints for leaks.
2. Flow test, the water into the medicine cabinet, a certain pressure selected, the manual switch is turned on for a minute, so that the liquid flow into a container, to measure the amount .
3. Effective spray rate determination, the best selection of fan-shaped nozzle nozzle, spraying nozzle when given the height, pressure, speed, swinging around, do not spray, spray evenly to ensure that field operations.
4. Walking speed, average walking speed of 1.0 -1.3 m / sec.
Secondly, the chemical liquid preparation, according to the size of the spray area to develop effective chemical solution.
1. First kits plus half a bucket of water.
2. Preparation of liquor, for when you mix the two agents were prepared in two containers liquor; if it is a wettable powder formulation liquor, should first add a small amount in the container of water, while stirring liquor agents, can not remember dosing once too.
3. WP should first mother liquor kits, then add cream of the mother liquor kits.
4. Finally, the medicine chest filled with water, shake his hand so that the liquid and mix well.
Finally, field operations, do a good job in all the pre-order, it begins to spray.
Note that when spraying nozzle direction consistent with the wind, spray rate in the order of the first land downwind outward , avoid body contact with liquid. When the pressure reaches a predetermined state, the open switch spraying. While maintaining the outward hand downwind lance and spray and wind direction. When spraying pressure and speed should be consistent with the direction of highly stable spray quality assurance. Spray finished drugs, use clean water kits, lance, nozzles and hoses and other components, and the medicine cabinet to dry.
