Problems solved by technology

[0005] One of the important differences between pak choy and other vegetables is that the growth period is short, especially for pak choy in summer, it only takes more than 20 days from planting to harvesting. If the control of flea beetle is not effective, it will cause serious losses.

If pesticides are used for control, the short application interval will cause a large amount of pesticides to remain in the vegetables, causing major hidden dangers to human health.

Although the agricultural control of flea beetle has also been reported, most of them have not been popularized due to poor results.
