Hello, I'm asking if my celery seedlings have rotten roots and yellow buds. What kind of pesticide is better?

Root rot of celery is mainly caused by longitudinal crack at the base of petiole due to boron deficiency, and then soft rot occurs. At first, there was a water-soaked lesion at the petiole, which spread soft rot and smelled bad. The outer leaves of the diseased plants withered and turned yellow.

Prevention and control measures: disinfect the soil before planting, and use 2 ~ 3 kilograms of borax as base fertilizer per mu before planting. Trim boron fertilizer solution should be sprayed during the growth period, and 50% dt or kocide plus agricultural streptomycin can be sprayed 2 ~ 3 times after the onset.
