Problems solved by technology

However, when the existing diquat is used in conjunction with a commercially available synergist, the diquat water agent can effectively contact and kill the foxtail, but its effect on curbing the greening of the foxtail is poor, and it has little effect on the improvement of the efficacy of the diquat water agent. not obvious

preparation example Construction

[0046] The present invention also provides a preparation method of a high-viscosity synergistic diquat special synergist, which specifically follows the steps of operation:

[0047] Step 1: Add the mixture of triethanolamine lauryl polyoxyethylene ether sulfate and surfactant PCA-Na into a reaction kettle filled with deionized water, and stir at 20-80°C for 5-10min until uniform;

[0048] Step 2: Add fatty alcohol polyoxyethylene ether-3-carboxy-1-sulfopropionate disodium salt, 3-sulfopropyl hexadecyl dimethyl ammonium, dibasic lead stearate and poly Add ethylene glycol to the product of step 1, stir and dissolve, add sodium diisobutyl sulfonate, and stir at 100-300r / min for 20-30min until uniform;

[0049] Step 3: Add organic silicon and sodium oleic acid sarcosinate in batches to the product of step 2, supplement with deionized water, stir for 5-10 minutes until evenly mixed, and you can obtain high-viscosity synergistic diquat special booster potency.

Embodiment 1

[0051] Get the following mass ratio materials: add deionized water to the reactor, start stirring, add mass ratio of 7% lauryl polyoxyethylene ether sulfate triethanolamine and 2% surfactant PCA-Na, stir and heat to 60°C, and stir at this temperature for 5-10min until uniform; then add 20% fatty alcohol polyoxyethylene ether-3-carboxy-1-sulfopropionate disodium salt, 8% 3- Sulfopropyl cetyl dimethyl ammonium, 6% dibasic lead stearate, 3% polyethylene glycol and 6% sodium diisobutyl succinate sulfonate, and in 100 Stir at -300r / min for 20-30min until uniform; then add 2% silicone and 7% sodium oleic acid sarcosinate in batches, and finally add deionized water, stir for 5-10min until uniform.

[0052] In conjunction with the added substance (by mass percentage) of embodiment 1, carry out following detection:

[0053] (1) Viscosity determination of the prepared high-viscosity synergistic diquat special synergist:

[0054] Instrument: NDJ-79 rotary viscometer (Jiangsu Tongjun Te...

Embodiment 2

[0068] Get the following mass ratio materials: add deionized water to the reactor, start stirring, add 6% lauryl polyoxyethylene ether sulfate triethanolamine and 2% surfactant PCA-Na in mass ratio, stir and heat to 60°C, and stir at this temperature for 5-10min until uniform; then add fatty alcohol polyoxyethylene ether-3-carboxy-1-sulfopropionate disodium salt with a mass ratio of 25%, 8% of 3- Sulfopropyl cetyl dimethyl ammonium, 6% dibasic lead stearate, 3% polyethylene glycol and 6% sodium diisobutyl succinate sulfonate, and in 100 Stir at -300r / min for 20-30min until uniform; then add 2% silicone and 7% sodium oleic acid sarcosinate in batches, and finally add deionized water, stir for 5-10min until uniform.

[0069] According to the test method of Example 1, the pH value of the high-viscosity synergistic diquat special synergist prepared by this formula is 5.6, the viscosity is 365mPa.s, the surface tension is 16.9mN / m, and the foam height is 16mL.

Abstract

The invention discloses a high-viscosity synergistic type synergist special for aquacide. The high-viscosity synergistic type synergist is prepared from the following matters (in percentage by mass):10 to 30 percent of fatty alcohol polyoxyethylene ether-3-carboxyl-1-disodium sulfo-propionate, 5 to 10 percent of dodecyl polyoxyethylene ether-triethanolamine sulfate, 5 to 10 percent of 3-sulfopropyl cetyl dimethyl ammonium, 5 to 10 percent of dibasic lead stearate, 5 to 10 percent of diisobutyl sodium sulfosuccinate, 5 to 10 percent of sodium creatine oleate, 1 to 5 percent of a surfactant PCA(Pyrrolidone Carboxylic Acid)-Na, 1 to 5 percent of polyethylene glycol, 1 to 5 percent of organosilicone and the balance of deionized water. According to the high-viscosity synergistic type synergist disclosed by the invention, surfactants in different functions and effects are compounded, and each surfactant can have a better function under the action of other surfactants, so that the high-viscosity synergistic type synergist has good properties of wettability, spreadability, permeability and the like, is capable of effectively carrying out contact poisoning on setaria viridis, successfullycontrolling reviving of the setaria viridis, prolonging the reviving time, prolonging the lasting period, reducing the pesticide application frequency and controlling the waste of original medicine,and is environment-friendly; meanwhile, the high-viscosity synergistic type synergist is beneficial for increasing the pesticide effect of an aquacide water solution.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a special synergist for high-viscosity synergistic diquat and a preparation method thereof. Background technique [0002] Diquat is a contact-killing herbicide, which can be quickly absorbed by green plant tissues and quickly loses its activity after contacting with soil. It is used for weeding in fields, orchards, non-cultivated land, and before harvesting. It is also a widely used in foreign countries. Aquatic weed herbicide, when used in the field, often kills the grown weeds before and after the crops are sown and before the seedlings, or uses directional spraying between the rows after the crops grow up. At the same time, diquat is also a contact Desiccant, can be used as a dry / ripening agent before and after crop harvest and a desiccant for seed crops. However, when the existing diquat is used in conjunction with a commercially available synergist, the diquat water agen...
