#CucumberBeetleControl #BoricAcid #HomeGardening The cucumber beetles have arrived. Every year, they pest holes in my cucumber leaves. Even after spraying pesticides, they're back the next day. I finally found a way to put an end to this cycle, and it's been sitting on my kitchen shelf for ages. 🎓 Welcome to the Japan Agricultural University Channel! This time, we'll introduce a method discovered in the 1960s by an agricultural extension worker in Hokkaido, which had been forgotten for 60 years.
