At present, there are as many as seven or eight varieties of herbicides available on the market. Which type of herbicide is the best for rice fields? In Rudong County, this year the county promoted the best "Yinhai Brand" herbicide. Rice is a staple crop in Rudong County, and it is also the main channel for farmers in the county to increase their income. In addition, the county’s rice has been promoting drought and sparse planting techniques for many years. This year, a large-scale demonstration machine transplanted the new technology, which is the transfer of medium and small seedlings to rice. Herbicide selection requirements are high. Therefore, we especially remind farmers that the use of "Yinhai Brand" herbicide in rice fields is not only effective for weed control but also safe for rice production.
