Embodiment 1
[0032] Example 1: Glyphosate isopropylamine salt, flazasulfuron and 2,4-D dimethylamine salt water dispersible granules
[0033] The ingredients in Table 1 are mixed uniformly according to the proportions, pulverized by airflow, and 0.2 times of the total weight of water is added for mixing, extrusion, and granulation. After drying and sieving, water dispersible granules are obtained.

Embodiment 2
[0036] Example 2: Wettable powder of glyphosate isopropylamine salt, flazasulfuron and 2,4-D dimethylamine salt
[0037] The components in Table 2 are mixed uniformly according to the proportion, and then pulverized by an ultrafine pulverizer to obtain a wettable powder.

Abstract
The invention discloses a composite herbicide and application thereof. The composite herbicide is prepared from glyphosate, flazasulfuron, auxin analogues, pesticide carriers or auxiliary materials, the mass content of glyphosate is larger than or equal to 10%, the mass content of flazasulfuron is larger than or equal to 0.1%, the mass content of auxin analogues is larger than or equal to 2%, andthe total mass content is 100%. The transgenic crop provided by the invention has remarkable tolerance to the composite herbicide provided by the invention. The herbicide can selectively kill weeds after post-emergence spraying, but has no harm to the transgenic crops. Compared with an existing herbicide, the composite heavy herbicide provided by the invention is move valuable and has the advantages that the weed control spectrum is wider, the control effect is better, the weed control time is longer, and the resistance of weeds to the herbicide is favorably delayed.
Description
[0001] (1) Technical field [0002] The invention relates to a compound herbicide and its application, in particular to a compound herbicide of a variety of herbicides and a method for using these compound herbicides to efficiently control weeds of transgenic herbicide-resistant plants. [0003] (2) Background technology [0004] Weed control is essential for high and stable crop yields. Herbicides are currently the most important technical means for controlling weeds. In order to be able to continuously and efficiently use herbicides to control weeds, two problems must be solved in production and application: [0005] One is to solve the technical problem that herbicides can selectively control weeds without harming crops. Solving this problem is generally achieved by introducing herbicide-resistant genes into crops to obtain herbicide-tolerant genetically modified crops. At present, genetically modified crops that are resistant to glyphosate, glufosinate, 2,4-D and dicamba have be...
