Abstract
The present invention relates to a kind of synergistic compositions, are made of synergistic component, herbicidal active component and insecticides adjuvant, and synergistic component can be one kind in brassin lactones or propionylbrassinolide, and herbicidal active component can be one kind in glufosinate-ammonium or smart glufosinate-ammonium.The weight ratio of synergistic component and herbicidal active component in the composition is 1000~1000000：1；The present invention reduces the dosage of herbicidal active component while improving herbicidal effect, to reduce pesticide to the harm of crop around and environmental pollution, slows down the generation of resistant weed.
Description
Technical field
The present invention relates to compound pesticides application technical fields, are prevented and kill off for agricultural weed.
Background technology
Glufosinate-ammonium with its wide spectrum, it is environmentally friendly and it is less toxic and become the most important herbicide in the world, belong to broad-spectrum touch-out type,
Systemic action is not strong, and glufosinate-ammonium first kills leaf, can be conducted in plant xylem by plant transpiration effect.Glufosinate-ammonium becomes
World's second largest herbicide, however after 2008, as a series of pesticide market glufosinate-ammonium products in China's are released, glufosinate-ammonium price
Significantly decline, revolutionizes the previous use pattern of glufosinate-ammonium, it is a large amount of single and more in various crops/bare place repetition
Secondary use, glufosinate-ammonium is using more prevalent, and dosage dramatically increases, and glufosinate-ammonium is used for multiple times every year in same arable land.For same work
Depending on unduly and being used for a long time with mechanism herbicide will certainly cause weed community to change and generate resistance, in selective pressure
Under force effect, weeds generate it resistance or patience and will significantly increase.
End on May 31st, 2018, China's registration glufosinate-ammonium product alreadys exceed 360, and glufosinate-ammonium is faced with huge choose
War and pressure.Under the long-term a large amount of high intensity selection pressure using glufosinate-ammonium, in the farmland in the multiple areas of man of China
It is found that glufosinate-resistant weeds, the Weed Resistances rapid development such as especially common eleusine indica, beggar-ticks and miliary fimbristylis herb.And
And glufosinate-ammonium using effect under high temperature, cryogenic conditions significantly reduces, and usually falls flat in winter with summer.
By the screening of compounded formula, rational formula is filtered out, practical effect can be effectively improved, reduces medication
Amount reduces cost, mitigates the pollution to environment, delays the generation of herbicide resistance, extends the Pesticide use service life, is agriculturally miscellaneous
The important means that grass comprehensive is administered.
Brassin lactones are a kind of novel sterols plant endogenous hormones, and there are mainly two types of the BR kinds of production, one is
Referred to as table brassin lactones (epi-BL), the conformation of its methyl on 24 is with BL on the contrary, also a kind of being known as high brassin
Lactone (homo-BL), 24- methyl are changed to ethyl in its molecule, both brassin lactones have presence in nature.
Hydroxyl is changed in the chemical constitution of long-acting rapin lactones TS303 (adopted name propionylbrassinolide), especially
Two hydroxyls originally are changed to two propionos.
Invention content
The object of the present invention is to provide a kind of Synergistic herbicide compositions, and while improving herbicidal effect, reducing weeding has
The dosage for imitating ingredient, slows down the generation of resistant weed.
Technical solution of the present invention：A kind of synergistic composition is made of synergistic component, herbicidal active component and insecticides adjuvant,
Synergistic component can be one kind in brassin lactones or propionylbrassinolide, and herbicidal active component can be glufosinate-ammonium or essence
One kind in glufosinate-ammonium.The weight ratio of synergistic component and herbicidal active component in the composition is 1000~1000000：1；Increase
It is 5%~85% to imitate the weight percentage of ingredient and herbicidal active component weight summation in Herbicidal combinations, remaining is agriculture
Medicine auxiliary agent.
The insecticides adjuvant includes but not limited to：It is solvent, emulsifier, wetting agent, dispersant, thickener, antifoaming agent, antifreeze
Agent, preservative, stabilizer, binder, disintegrant, solid carrier, liquid-carrier, surfactant, deionized water etc..
Herbicidal combinations of the present invention can be prepared into a variety of application forms used in suitable agricultural production, relatively good agent
Type has dispersible oil-suspending agent, aqua, microemulsion.
The production technology of the various application forms of Herbicidal combinations belongs to existing known technology, and details are not described herein.
In order to overcome the problems, such as that glufosinate-ammonium herbicidal effect in production application reduces, we are according to brassin lactones as one
The mechanism of action of Physiology and biochemistry effect and glufosinate-ammonium weeding of the plant growth regulators in plant, brassin lactones are drawn
The effect link for entering glufosinate-ammonium weeding increases glufosinate-ammonium herbicidal effect in the hope of improving bioactivity of the glufosinate-ammonium to killing weeds
While, the unit dose of glufosinate-ammonium can be reduced, generation of the weeds to the resistance of glufosinate-ammonium is slowed down, to reduce glufosinate-ammonium to ring
It pollutes in border.
Compared with published technology, there are following advantages by the present invention：
1, it being combined with glufosinate-ammonium by brassin lactones so that the herbicide has apparent synergistic effect, lowers usage amount,
Low cost increases environmentally friendly.
2, it is combined with glufosinate-ammonium by brassin lactones, improves glufosinate-ammonium in adverse circumstance using effect, ensure glufosinate-ammonium not
With climatic environment using effect.
3, brassin lactones and the mechanism of action of glufosinate-ammonium are inconsistent, and the long-term single use of pesticide can be overcome to easy to produce
The shortcomings that resistance, to the comprehensive treatment important in inhibiting of Weed Resistance.
