Description
Technical field
The present invention relates to pesticide field, more particularly to a kind of broad spectrum type diquat dibromide compound synergic agent and preparation method thereof.
Background technology
Diquat dibromide belongs to bipyridyl herbicides together with paraquat, and bipyridyl herbicides are by ICI companies（Now ownership is first just
Up to company）Developed in 1958, be the natural disposition cauline leaf process agent of going out of absorbability contact killing type, it is quick and upward in non-symplast
Conduction, but do not conducted downwards in bast, therefore weeds underground part cannot be killed.Such herbicide has two important grass of kind hundred
Withered (paraquat) and diquat dibromide (diquat).1,2 one one 2,2 a pair of pyridine of ethylidene of diquat dibromide chemical name, two father-in-law's salt, has
Alginates and dibromo salt, other titles Reglone, Aquacide etc., are with dibromo salt (diquatdibromide) in use
It is main.Product rat acute LD50 is 231mg/kg, moderate toxicity.Bipyridyl herbicides can be rapid, strong by soil colloid
Strong absorption, loses activity so once contacting soil, therefore extremely safe to succession crop.The product are widely used in crop field, fruit
Garden, bare place, gather in the weeding such as preceding, is also a widely used aquatic weed herbicide abroad.During for crop field, usually
It is that before seedling kills the big grass grown before crop sowing or after broadcasting, or after crop seedling is grown up, using directed spraying in the ranks.Together
When, diquat dibromide or a contact drier, can be used as urging withered/ripe and seed crop drier before and after crop harvesting.When
When urging withered for potato haulm, 420-480g/kg of dosage, when seed crop is dried, 392-784g/kg of dosage, anti-water removal
During raw weeds, 588-2950g/ha of dosage.Diquat dibromide is mainly used for broad leaved weed plot in the majority, more than grassy weed
When, to strengthen preventive effect, the mixture of it and paraquat can be used.
Diquat dibromide is identical with paraquat and similarity is very much：All belong to bipyridyliums, be similar compound；All it is 1958
Found in year, developed and promoted by ICI companies；All belong to absorbability contact killing type steriland herbicide, the mechanism of action is also identical, all
It is photosynthetic electron transport chain diversion agent；All there is weeding and urge withered double action, therefore they are all both weeding on international market
Agent, and be to urge withered dose, paraquat registration are used on the crops such as cotton, wheat urge withered, and diquat dibromide registration is for potato, big
Urged on the crops such as beans, cotton, rice, wheat withered；Status on global agrochemical market is close, at present, as the country is on hundred
After careless No. 1745 ban of low water agent are announced and implemented, i.e., from 1 day July in 2014, the registration of revocation paraquat aqua and production are permitted
, production can be stopped, retaining the outlet of Mu Yao manufacturing enterprises aqua overseas using registering, allow to specialize in outlet production, July 1 in 2016
Day stop aqua selling and use at home.And paraquat dosage is to be only second to the second largest herbicide of glyphosate, once it is domestic
Forbid selling, then diquat dibromide will become the strong substitute of paraquat aqua.So innovation is developed and matched somebody with somebody with excellent
5 property and the Additives Products of good weeding drug effect performance are the technical barriers that the current country must capture.
Domestic diquat dibromide aqua technology existing at present generally has no applicability requirement, is the non-selection natural disposition aqua that goes out, it is lacked
Point is as follows：
（1）It is poor for applicability：Existing diquat dibromide auxiliary agent general applicability is poor, cannot be general to various types of mother liquor and content, wide usage
Limit to
（2）It is poor to soak plate-out ability：For diquat dibromide aqua prepared by the prior art generally for soaking no requirement (NR), wetting time is general
In 180s or so, wetting effect needs to strengthen
（3）It is building performance not notable：For some technologies using sodium sulfate of polyethenoxy ether of fatty alcohol as synergist, drug effect is for 2 weeks,
Duration of efficacy is shorter.
（4）Extreme condition resistance is poor：Technically drug effect has a great influence diquat dibromide preparation in extreme circumstances at present, frost resistance
Have much room for improvement with high temperature resistance.
（5）The dilution stability of preparating liquid is poor, flocculation sediment phenomenon easily occurs, influences the stability of product quality.
The content of the invention
