Technical field
The present invention relates to pesticide field, is specifically related to dispersible oil-suspending agent of a kind of glufosinate-ammonium and preparation method thereof.
Background technology
Glufosinate-ammonium category phosphonic acid herbicide, is glutamine synthetase inhibitor, has the non-selective of part systemic action
Contact weedicide.Glufosinate-ammonium toxicity is low, be easy to degraded in the soil, to crop safety, be not easy drift, herbicidal spectrum is wide, activity is high,
Good absorbing, environmental pressure are small, weed eradication is rapid, can quickly kill more than 100 kinds of grass family and broad leaved weed.Meanwhile and generation
The second largest genetically modified crops herbicide-tolerant in boundary, generally should in countries such as Japan, South Korea, Southeast Asia, America, Europe
With.At home, with the large area of glyphosate, reuse, already lead to a large amount of weeds and produce resistances, and paraquat aqua by
It is too strong in toxicity, stopped using in July, 2016, popular anchor man of the glufosinate-ammonium into paraquat.It can be seen from the above that paraquat water
After agent disabling, the prospect of glufosinate-ammonium is very wide.
Over the past two years, action of each means of agricultural production enterprise in glufosinate-ammonium was frequent.Recognize from Chinese pesticide Information Network, 2012
The registration card of year glufosinate-ammonium product only has 11, increases 102 within 2016, wherein, active compound 23,73 (70, preparation
Aqua, 3 soluble granules), it is seen that register most for glufosinate-ammoniumaqua aqua.But glufosinate-ammoniumaqua aqua have two aspect restriction because
Element, the first glufosinate-ammonium belong to salt in itself, cannot be coexisted in conventional surfactant in aqueous systems, and auxiliary agent is matched and is required
It is higher.Second glufosinate-ammoniumaqua aqua is higher to the susceptibility of environment, and temperature and humidity has a great impact the drug effect of glufosinate-ammonium.It is wet
When spending relatively low, plant epidermis drying stomata is closed, leaf rolling, is unfavorable for the absorption of glufosinate-ammonium；Under cryogenic, glufosinate-ammonium
Reduced by the ability of cuticula and cell membrane, so as to influence herbicidal effect.When environment is unfavorable, glufosinate-ammonium herbicidal effect is paid no attention to
Think.
Dispersible oil-suspending agent decentralized medium is oily, and mostly mineral oil or vegetable oil, document report vegetable oil and pesticide
