In recent years, Urumqi, Changji and other popular cabbage butterfly particles virus. According to foreign reports, the virus in the soil to maintain its infectivity up to a few years, thus contaminating crops, causing the population of the virus epidemic, the big pink butterfly population decreased significantly. In order to take advantage of this virus pest control, we made it into preparations and conducted field control trials.
