Spinach aphids: 

Spray the pesticide from the early stage of the aphids, once every 10 days or so, and spray 1 to 2 times in a row.

Celery aphids: Spray the pesticide from the early stage of aphids, once every 7-10 days, and spray about 2 times in a row. The spraying dosage of pymetrozine is the same as that of "spinach aphids"

Celery aphids:

Spray the pesticide from the early stage of aphids, once every 7-10 days, and spray about 2 times in a row. The spraying dosage of pymetrozine is the same as that of "spinach aphids"

Notes: 

Pymetrozine cannot be mixed with alkaline agents and fertilizers. When spraying continuously, pay attention to alternate or mix with different insecticides to delay the development of insecticide resistance in pests. Spraying should be timely and thorough, especially spraying to the parts where the pests are infesting. This agent is toxic to bees and is prohibited during the flowering period of fruit trees and beekeeping sites.
