Abstract
The invention relates to a preparation method of a nicosulfuron dispersible oil suspension agent. The method is characterized in that a nicosulfuron original drug is adopted as a raw material, calixarene is adopted as a dispersant, an emulsifier is added, and plant oil is adopted as a solvent; and the calixarene is p-tert-butylcalix[6]arene. In the invention, the nicosulfuron original drug is as the raw material, the novel environmentally-friendly plant oil is adopted as the solvent, and the dispersant novel calixarene and the emulsifier are added to prepare the nicosulfuron dispersible oil suspension agent, so the product suspension rate reaches above 94%.
Description
Technical field
The preparation method who the present invention relates to a kind of nicosulfuron dispersibility oil-suspending agent, belongs to preparation technique of pesticide field.
Background technology
Nicosulfuron is systemic herbicide, can be weeds cauline leaf and root absorption, in plant corpus, conduct subsequently, cause sensitive plant growth retardation, cauline leaf chlorisis, withered gradually, generally death in 20-25 days, but time that need be longer to some perennial weed in the situation that temperature is lower.Dispenser good drug efficacy before 4 leaf phases after bud, when seedling is large, dispenser drug effect declines.This medical instrument has the front activity of weeding of bud, but active in low after bud.
It can be for preventing and kill off annual and perennial grassy weed, part broad leaved weed.Test shows that the strong weeds of Drug Sensitivity are had to And-gather grass, green foxtail, wild oat, Amaranthus retroflexus; The medium weeds of susceptibility have Ben Shi knotweed, rule grass, kitchen garden, Monochoria vaginalis, Siberian cocklebur and piemarker, nutgrass flatsedge; The poor weeds of susceptibility mainly contain lamb's-quarters, black nightshade, Commelina communis, summer cypress and weasel hemp nettle.
Suspendability is an important indicator that ensures nicosulfuron herbicide performance, therefore how to improve its suspendability and just seems very important.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of preparation method of the nicosulfuron dispersibility oil-suspending agent that can improve nicosulfuron Suspension index.
The technical solution used in the present invention is for this reason: the present invention carries out according to the following steps: taking the former medicine of nicosulfuron as raw material, taking calixarenes as dispersant and add emulsifier, taking vegetable oil as solvent; Described calixarenes is to tert-butyl-calix [6] aromatic hydrocarbons.
Described vegetable oil is the mixture of soybean oil and tea oil, and both mass ratios are: soybean oil: tea oil=60-80%:20-40%.
Described mass ratio is: soybean oil: tea oil=68%:32%.
Vegetable oil is the 6%-12% of nicosulfuron quality.
Advantage of the present invention is: the present invention adopts taking the former medicine of nicosulfuron as raw material, and novel environment friendly plant oil is solvent, and adding Calix aromatic hydrocarbons is dispersant and emulsifier processing cigarette Sulfometuron Methyl dispersibility oil-suspending agent, and product suspensibility is reached more than 94%.
Embodiment
Embodiment mono-:

Described vegetable oil is the mixture of soybean oil and tea oil, and both mass ratios are: soybean oil: tea oil=68%:32%.
Vegetable oil is 10% of nicosulfuron quality.
Suspensibility reaches 97.2% after testing.
Embodiment bis-:
The present invention carries out according to the following steps: taking the former medicine of nicosulfuron as raw material, taking calixarenes as dispersant and add emulsifier, taking vegetable oil as solvent; Described calixarenes is to tert-butyl-calix [6] aromatic hydrocarbons.
Described vegetable oil is the mixture of soybean oil and tea oil, and both mass ratios are: soybean oil: tea oil=72%:28%.
Vegetable oil is 8% of nicosulfuron quality.
Suspensibility reaches 96.4% after testing.
Embodiment tri-:
The present invention carries out according to the following steps: taking the former medicine of nicosulfuron as raw material, taking calixarenes as dispersant and add emulsifier, taking vegetable oil as solvent; Described calixarenes is to tert-butyl-calix [6] aromatic hydrocarbons.
Described vegetable oil is the mixture of soybean oil and tea oil, and both mass ratios are: soybean oil: tea oil=62%:38%.
Vegetable oil is 12% of nicosulfuron quality.
Suspensibility reaches 95.3% after testing.
Through testing:
The corn 3-4 leaf phase, weeds all sprout and mostly are 5cm left and right plant height, cauline leaf spraying.With 4% suspending agent 40-70ml/ mu (summer corn), 70-110ml/ mu (northern spring corn), be watered 30kg/ mu and spray.
Improve 6% according to its weeding rate of nicosulfuron dispersibility oil-suspending agent of implementing 1 preparation than embodiment bis-, improve 10% than embodiment tri-.
