Problems solved by technology

[0005] Due to the characteristics of Mikania micrantha, there is currently no professional control agent for Mikania micrantha on the market that is as effective as farm weeds. In the field of chemical control, 18% of 2,4-D microemulsions have a certain quick-acting effect within 12 hours after application, and 25-40 The second chronic drug effect of the day caused the death of Mikania micrantha, making it difficult for branches and seeds to germinate. It is safe for grasses and weeds that do not contain terpenes and essential oils. It has the effect of killing weeds and restoring ecology; Such as plantains, yams, melons, etc. have serious drug damage to death
It cannot be used as a general herbicide, but its mechanism of killing Mikania micrantha has not been fully understood. Light rain in a short period of time after the drug has a synergistic effect

Embodiment 1

[0038] Example 1 Processing of solid preparations of 2,4-D acid and clopyralid, 2,4-D acid ammonium and clopyralid

[0039] Combining 2,4-D acid (A) with clopyralid (B), 2,4-D acid (A) and amiloride (C) in different proportions and contents, as shown in Table 1 Proportion of adjuvants Add the auxiliaries and mix them evenly to prepare the corresponding preparations; the composition of the preparations mainly includes active ingredients, surfactants, fillers and other agriculturally acceptable adjuvant components. The weight percentage of 2,4-D acid in the composition is 5%-85%, preferably 5-40%; the weight percentage of clopyralid in the composition is 5-85%, preferably 5- 40%; the weight percentage of amiloride in the composition is 5-85%, preferably 5-40%. The weight percent ratios of A:B and A:C are both: 5:85-85:5, preferably 5:40-40:5. The processed preparation was placed at 54±2 degrees Celsius for 2 weeks, and there was no agglomeration of the medicine, and there was ...

[0042] Example 3 Typical formulation of 2,4-D acid and clopyralid wettable powder preparation of the present invention

[0043] The typical formulation of 2,4-D acid and clopyralid wettable powder is as follows:

[0044] Total content of 2,4-D acid and clopyralid: 5%-85% (2,4-D acid: clopyralid 5%: 85%-85%: 5%)

[0045] Sodium Lauryl Sulfate 1-5%

[0046] Sodium lignosulfonate 2-8%

[0047] Kaolin or diatomaceous earth make up 100%

[0048]The preferred ratio of 2,4-D acid:clopyralid is 5%:40%-40%:5%.
