Embodiment Construction

[0020] Respectively according to pendimethalin and thifensulfuron-methyl (by mass ratio) formula 1=80:1, formula 2=60:1, formula 3=40:1, formula 4=20:1, formula 5=11:1 Five compound herbicide examples of the present invention were prepared in five proportions, and the biological activity determination and farmland drug efficacy test research of Duojiejiemai, Japanese Kan Mai Niang, Beef Chickweed, and Popona were carried out indoors, and the results were as follows:

[0021] 1. Determination of the synergistic effect (co-toxicity coefficient) of the pendimethalin and thifensulfuron-methyl compound on wheat field jellygrass, japonica, chickweed, and popona.

[0022] Pendimethalin, thifensulfuron-methyl and their compound combinations were used to measure the biological activities of japonica, Japanese kansui, cow chickweed and popona indoors. The method was in accordance with NY / T1154.7-2006 "Compound "Assessment of Joint Effect of Matching" was implemented.

Abstract

The invention discloses an application of a composite herbicide in prevention and removal of weeds in a wheat field, wherein the composite herbicide comprises the following effective components: pendimethalin and thifensulfuron methyl, and the mass ratio of pendimethalin to thifensulfuron methyl is (11-80):1. The composite herbicide is especially suitable for preventing and treating aegilops tauschii, alopecurus japonicas, malachium aquaticum or veronica didyma in wheat fields. The composite herbicide disclosed by the invention is sprayed on soil after winter wheat is sown and before seedlingemergence, and can effectively prevent and eliminate the harm of weeds such as aegilops tauschii and veronica didyma in a dry and dry crop rotation area; the herbicide can effectively prevent and eliminate harm of weeds such as alopecurus japonicas, amur foxtail, sclerochloa kengiana and malachium aquaticum in a paddy-upland rotation area, is convenient to operate, can prevent aegilops tauschii and alopecurus japonicas from generating drug resistance, and has a good application prospect and huge market potential.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to the application of a compound herbicide in controlling weeds in wheat fields. Background technique [0002] In recent years, due to the long-distance cross-regional operation of wheat harvesters, the replacement of new wheat varieties, the large-scale all-in-one supply, and the extensive farming system have also aggravated the occurrence of knotty wheat to a certain extent; The long-term use of fertilizers and a single herbicide species has led to the evolution of the weed community in the wheat field, and the control of the original dominant species of weeds has led to the increase of grass weeds such as japonica and japonica and become the current high-level weeds. Vicious weeds in fertilized wheat fields. [0003] Among them, S. chinensis, also known as rough goat grass, is a worldwide malignant weed, mostly born in barren grasslands or wheat fields, and is more harmful....
