Problems solved by technology

[0007] However, because fenflumezone is an imported drug, its import volume is limited and its price is high, so its use is limited
In addition, fenfentrazone is not effective in controlling broad-leaved weeds and sedge weeds

Abstract

Relating to the technical field of pesticides, the invention discloses a corn post-emergence compound herbicide containing topramezone and thiencarbazone-methyl. The active ingredient of the compound herbicide is composed of topramezone and thiencarbazone-methyl in a weight ratio of 0.1-80:0.1-80. The compound herbicide provided by the invention can control corn field annual gramineous weed, also can control broadleaf weed and nutgrass flatsedge, has significant weeding effect and obvious synergistic effect, also can control weed in the whole growth period by one pesticide application, and has no influence to succeeding crops, thus being an ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a corn post-emergence compound herbicide containing the active ingredients of fenflumezone and thiazone-methyl. [0002] technical background [0003] Corn is not only an important food crop in my country, but also an important feed crop. In recent years, with the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn has continued to increase. In 2012, my country's corn planting area reached 39.949 million hectares, second only to rice, becoming the second largest planting crop, and there is still an increasing trend. Weeds in cornfields are common and of various types. In particular, summer maize weeds in the Huang-Huai-Hai River Basin are serious, and the area of ​​weed damage accounts for 82% to 96% of the planted area in this area, and the area of ​​moderate damage is 64 to 66%. Corn seedlings suffer th...
