Before starting, before the quality misting machine is powered on (before the switch is turned on), it is necessary to carefully check whether all parts are complete and complete, especially whether the connection parts are loose, whether the toothed plate rotates flexibly, and whether the medicine supply parts are smooth or leaking. medicine, whether the windshield is open.

In short, keep the quality misting machine in good condition. Determine the use of pesticides and dosages, and do a good job of phytotoxicity testing. According to the control objects, crop types and their growth conditions, select the appropriate pesticides and determine the dosage per mu.

In order to avoid the occurrence of phytotoxicity, an phytotoxicity test should be carried out before large-scale spraying. The test method is: in the downwind of the quality misting machine operation area, choose an area of 2-3 square meters to spray the liquid 2-3 times larger than the normal spraying amount, and generally check whether there is any phytotoxicity on the next day. It is better if the time is appropriately longer. If there is no phytotoxicity, a large area can be sprayed.
