Herbicide for stem and leaf treatment of hemerocallis fulva

Abstract

The invention discloses herbicide for the stem and leaf treatment of hemerocallis fulva. The herbicide comprises the active ingredients including quizalofop-p-ethyl and fluroxypyr-mepthyl in the weight ratio of 2 to 7:8, wherein the active ingredients account for 25 to 37.5 percent of the total weight of the herbicide composition. The herbicide disclosed by the invention has a good herbicidal effect on hemerocallis fulva fields, is safe to crops, and is a compound herbicide with an ideal effect on preventing and controlling weeds in hemerocallis hybridus fields at present.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a herbicide used for treating daylily stems and leaves. technical background [0002] The development of chemical herbicide application technology in my country has been continuously improved. Through more than 60 years of experimental development, herbicides have formed a relatively complete and mature chemical herbicide system on rice, wheat, soybean, cotton, corn and some economic crops, and achieved remarkable results. economic and social benefits. However, chemical weeding in forestry, especially some low open-ground perennial flowers, due to the introduction of off-site and many years of planting, has resulted in the perennial perennials such as Imperata pratense, Cottage, Dawanhua, Field bindweed, and purslane. Root or vicious weeds, these weeds reproduce in large numbers with root buds and seeds, grow faster, and the aboveground part is removed, and the under...

Problems solved by technology

[0003] In recent years, Du E and others from Shandong Agricultural University reported that after transplanting and planting Hemerocallis grandiflora, 33% pendimethalin EC and 72% metolachlor EC were used for soil treatment and weed control tests and different concentrations of Sethoxydim and fluazifop-methyl were used for stem and leaf spraying to control potted Hemerocallis grandiflora gramineous weeds. However, the production nursery is often mixed with gramineous weeds and broad-leaved weeds, and it is necessary to expand the herbicidal spectrum. To achieve the purpose of effective weed control
