Although herbicides can eliminate weeds, the crops are guaranteed to be nutritious and healthy. But herbicides also have the downside, that is the phytotoxicity! It is understood that many herbicides are very influential to the next crop. The following small series sort out the effects of common herbicides on the lower crops. For growers who have used these herbicides, pay attention to the cultivation of the lower jaw!
