Abstract

The invention relates to the field of pesticides, in particular to a corn field herbicide as well as a preparation method and application thereof. According to the corn field herbicide, by using nicosulfuron, fluroxypyr and tembotrione which are compounded, weeds in corn fields can be efficiently prevented and treated, and particularly, good prevention and removal effects can be achieved on various malignant broadleaf weeds such as commelina communis, cirsium setosum, sonchus brachyotus, convolvulus arvensis, fallopia convolvulus, cleavers, alternanthera philoxeroides, rhizoma alismatis, Viciasativa L, piemarker, nightshade, datura stramonium and acalypha australis; the applicant adds a thickening agent, a dispersing agent, an emulsifying agent and a solvent, so that deposition of nicosulfuron, fluroxypyr, tembotrions and the like on the leaves can be promoted, adhesion, wetting, spreading and permeation of the active ingredients on the leaves are promoted, and the effects of the active ingredients are brought into full play; and in addition, the herbicide provided by the applicant has good storage and dispersion stability and dumping property, and meets the requirements of a dispersible oil suspending agent.

Description

technical field [0001] The present invention relates to the field of pesticides, more specifically, the present invention relates to a cornfield herbicide and its preparation method and application. Background technique [0002] Corn is the third largest crop and the second largest food crop in my country. It is not only related to the total grain output of our country, but also an important feed crop and chemical raw material. However, the occurrence of weeds in corn fields is becoming more and more serious, and their resistance is becoming more and more The stronger it is, so the weeding of cornfields has attracted the attention and attention of farmers in our country. According to statistics, there are currently 43 species of weeds in 22 families, 38 genera, and common weeds include: barnyardgrass, crabgrass, goosegrass, foxtail, amaranthus, quinoa, purslane, bindweed, etc. The rapid growth of weeds will take all kinds of nutrients needed by corn, and the rapid reproducti...
