Problems solved by technology

[0006] In addition, in actual production and application, because the herbicidal effect of glyphosate is reduced under the conventional application rate, in order to improve the herbicidal effect of glyphosate, users arbitrarily mix it with other herbicides or non-pesticide ingredients, increase the dosage at will, Changing the method of use, etc., often leads to problems such as crop injury, human and animal poisoning, environmental pollution, and poor effect.

Abstract

The invention provides a glyphosate weeding composition containing uniconazole. Effective ingredients of the glyphosate weeding composition containing uniconazole include a glyphosate compound and uniconazole. In the glyphosate weeding composition, the glyphosate compound is glyphosate acid or a herbicidal active derivative thereof. The mass ratio of glyphosate to uniconazole is 100:(0.1-25). The glyphosate weeding composition containing uniconazole has the advantages that uniconazole and a glyphosate product are compounded, and the uptake and translocation effects of glyphosate in stems and leaves and the growth regulation effect of uniconazole are utilized and combined, so that the weeding composition has obvious synergistic effects, the initial effect time is shortened for 2-5 days, the usage amount of a herbicide is reduced by 20-50%, and control effects on some noxious weeds are better. The weeding composition provided by the invention has the advantages of broad spectrum, high efficiency, low toxicity, little pollution, high effect taking speed, low cost and convenience in application.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a glyphosate herbicidal composition containing uniconazole with synergistic activity. Background technique [0002] Generally, glyphosate has become the most important herbicide in the world due to its broad-spectrum, environmental friendliness and low toxicity. Due to its special mechanism of action, it is very slow for weeds to develop resistance to it. It was widely used from 1974 to 1993. In the 20 years since, there have been no reports of glyphosate-resistant weeds. However, after 1996, with the expansion of planting of a series of transgenic glyphosate-resistant crops, the previous use mode of glyphosate was completely changed, starting with a single use and repeated use at different growth stages such as pre-germination and post-germination , the use of glyphosate is becoming more and more common, and the amount of use has increased significantly. The use of glyphosat...
