Major Progress Made in the “Seventh Five-year Plan” During the “Seventh Five-year Plan”, great progress has been made in the fields of weed biology, ecology and the development and application of herbicides in our province. Has completed the transplanted paddy perennial weed - flat stalk grass national research topics, the successful introduction of the sweep Eritrea, the new Malchute, agricultural time, herbicide Dan and other new herbicides and screened a number of efficient , Economic, and safe one-time paddy field herbicides formula to complete the direct-seeded rice fields, cotton, fruit, mulberry, tea garden weed growth and decline of chemical control and a series of supporting technologies; in the field of wheat, the introduction of new herbicides such as Ge, Ophiopogon japonicus, wild swallow, paraquat enemies, so that it is long, superstar and other herbicides to control monocotyledonous weeds.
