The damage is small in spring, but the damage increases steadily toward autumn. I've heard that the more intense the heat, the greater the damage, and this year it seems that damage was widespread nationwide. There were more cases of this pest in my own field this year than usual. Due to the rapid warming of Japan, it is predicted that the damage caused by this pest will increase in the future. Please take note of the ecology of the common cutworm, the damage it causes to grapes, and the key points for countermeasures and control, and take proper measures and control. ▼Medicines featured in this video (link to Amazon) ・Phoenix Flowable https://amzn.to/3UWIUp0 ・Kotetsu Flowable This is a non-medicinal hazardous substance.
