After paraquat was banned in many countries, the amount of diquat, as the main alternative to the withering, increased sharply. With the ban on paraquat in Brazil from September 22, 2020, the import of diquat in Brazil has grown rapidly, from 3475 tons (Diquat cation Equivalents) in 2019 to 4940 tons in 2020, a year-on-year increase of 42%. Moreover, in 2021, Brazil's imports will further soar to 9843 tons, an increase of 550% compared with the average market demand in the past decade.
200g/L diquat SL is a common formulation among diquat SL. It is generally calculated as dibromide salt, and there are also 200g/L diquat cationic equivalents SL. The routine quality indexes of 200g/L Diquat SL are as follows:
200g/L Diquat SL | |
Content | Dibromide Salt Equivalents:200g/L±12 |
Diquat cation Equivalents:107g/L±6.5 | |
2,2 '- Bipyridine | ≤0.075% |
1,2-Dibromoethane | ≤0.001% |
PH | 4.0-8.0 |
Density | 1.12 |
Preparation color | Dark green, red, brown |
Viscosity | No-Claim,or100-200cps、200-300cps |
Persistent foaming | <60mL |
Diluted Stability | Dilute the standard hard water for 20 times, place it at 30 ℃ for 18h, and it is uniform and transparent without precipitation |
Diquat preparation generally adopts anionic/non-ionic composite additives,Mixed system of anionic and nonionic surfactants is a classic type in diquat adjuvants. Diquat adjuvants developed by us,has low surface tension and outstanding diquat efficacy. In addition, this type of adjuvant has a good viscosity form, even the viscosity of the preparation is very high, it can still maintain a good flow state and showed a good water solubility
Nonionic/zwitterionic compound or cationic/nonionic compound adjuvants are more cost-effective than anionic/nonionic compound adjuvants. In terms of performance, this type of adjuvant has good salt tolerance, and can still maintain the stability of the formulation when the quality of the diquat TK fluctuates.
The use of adjuvants with low surface tension can well wet the leaf surface, greatly reduce the loss of liquid herbicide, and achieve the purpose of reducing costs and increasing efficiency. Common adjuvants for Diquat SL are shown in the following table. If necessary, please consult:
