Abstract
The invention relates to botanical herbicide soluble powder and a preparation method thereof, and belongs to the technical field of herbicides. The botanical herbicide soluble powder specifically comprises 40-80% of soapberry testa extract, 10-15% of pesticide surfactant, and 5-50% of filling. The preparation method includes: using distilled water to dissolve the soapberry testa extract, and performing leaching; mixing well the pesticide surfactant, the filling and the distilled water, and performing leaching; and mixing well the solutions and performing spray-drying to obtain the botanical herbicide soluble powder. The botanical herbicide is applicable to post-seeding pre-emergence soil treatment and control and removal of farmland weeds.
Description
Technical field
The invention belongs to herbicide technology field, relate to a kind of plant resource weed killer herbicide, specifically relate to a kind of plant resource weed killer herbicide soluble powder that soapberry exosper extract is active component and preparation method thereof of take.
Background technology
Causing harm of farmland weed often causes a large amount of underproduction of crops every year.Use chemical herbicide to remain the Main Means of current weed control, but due to a large amount of and unreasonable use chemical herbicide, caused the problems such as environmental pollution, residue of pesticide and herbicide resistance, be subject to extensive concern.Therefore, exploitation is efficient, the new herbicides of low toxicity, low-residual, becomes problem in the urgent need to address.From plant, find bioactivator, and then the environmentally friendly agricultural chemicals of development of new, be the hot fields of the outer research of Present Domestic.
Soapberry (Sapindus mukurossi Gatren) is a kind of deciduous tree of Sapindaceae (Sapindaceae) Sapindus (Sapindus), originates on the south China Yangtze river basin and South East Asia Mainland various places, India and Japan.Research shows, contains multiple secondary metabolite in soapberry, and some have good biologically active, has been widely used in daily use chemicals, medicine and other fields.But so far not about the report of soapberry extract activity of weeding, the weed killer herbicide product that the soapberry exosper extract of not take is active component.Therefore, the plant resource weed killer herbicide product that soapberry extract is active component is take in exploitation, has wide market prospects.
Summary of the invention
The invention provides a kind of plant resource weed killer herbicide soluble powder that soapberry extract is active component and preparation method thereof of take.
The present invention adopts following technical scheme:
A kind of for preventing and kill off the plant resource weed killer herbicide of farmland weed, it is characterized in that, comprise soapberry exosper extract, surfactant and filler, specifically comprise following mass percent: soapberry exosper extract 40-80%, pesticide surfactant 10-15%, filler 5-50%.
Described pesticide surfactant is one or more in sodium lignin sulfonate, dodecyl sodium sulfate or lauryl sodium sulfate.
Described filler is one or more in anhydrous sodium sulfate, carbonic acid (hydrogen) sodium, carbonic acid (hydrogen) potassium, urea, soluble starch or glucose.
Soapberry exosper extract adopts one or more solvent extractions, the preparation in ethyl acetate, absolute ethyl alcohol, methyl alcohol or distilled water, and feed liquid mass ratio is 1: (6-10).
Soapberry exosper extract can be used for weed killer herbicide.
Described plant resource weed killer herbicide compound method, comprises the following steps:
(1) soapberry exosper extract is dissolved to suction filtration with distilled water;
(2) pesticide surfactant and filler are evenly mixed to suction filtration with distilled water;
(3) under agitation, the mixed solution that step (2) is formed mixes with the soapberry exosper extract that step (1) forms, and sprays dry, obtains plant resource weed killer herbicide soluble powder.
Weed killer herbicide of the present invention can be used for broadcasting the front soil treatment of rear seedling, prevents and kill off farmland weed.Compared with prior art, it is good, environmentally safe that plant resource weed killer herbicide of the present invention has herbicidal effect, and the weeds feature such as be difficult for developing immunity to drugs, has a extensive future.
Accompanying drawing explanation
Fig. 1 is the inhibitory action of pulvis of the present invention to red clover, above three wares for adding 0.25gL
-1after soapberry extract, below three wares be blank.
The inhibitory action of Fig. 2 pulvis of the present invention to balling romaine lettuce, above three wares for adding 0.25gL
-1after soapberry extract, below three wares be blank.
Embodiment
The present invention is described in further detail by the following examples, but should be appreciated that the present invention is not in following examples.
The preparation of embodiment 1:40% soapberry extract soluble powder
Soapberry exosper is air-dry, dry or in 40-60 ℃ of oven dry, pulverize, by solid-liquid ratio, add extraction solvent at 1: 10, dipping extraction 4h, repeats 3 times.Merge extract, spraying is dry, obtains soapberry exosper extract.By soapberry exosper extract 1k g, sodium lignin sulfonate 0.25kg, urea 0.75kg, anhydrous sodium sulfate 0.5kg, respectively with distilled water dissolving, suction filtration.Above-mentioned raw materials solution is mixed, spray-dried, obtain 40% soapberry extract soluble powder.
The preparation of embodiment 2:80% soapberry extract soluble powder
Soapberry exosper is air-dry, dry or in 40-60 ℃ of oven dry, pulverize, by solid-liquid ratio, add extraction solvent at 1: 6, dipping extraction 4h, repeats 3 times.Merge extract, spraying is dry, obtains soapberry exosper extract.By soapberry exosper extract 2kg, sodium lignin sulfonate 0.25kg, urea 0.25kg, respectively with distilled water dissolving, suction filtration.Above-mentioned raw materials solution is mixed, spray-dried, obtain 80% soapberry extract soluble powder.
Embodiment 3: the impact of soapberry exosper extract on plant seedling growth
Take Bermuda grass, the bent grass of crawling, annual bluegrass, red clover and balling romaine lettuce as for examination target plant, adopt agar powder mixing method to evaluate the activity of weeding of soapberry extract.
Table 1 soapberry exosper extract toxicity test result
To test plant, growth has strong inhibitory action to soapberry extract as seen from Table 1.The most obvious to the effect of the bent grass of crawling, annual bluegrass and Bermuda grass, the EC to root growth
50value is respectively 0.0392g.L
-1, 0.0505g.L
-1, 0.1217g.L
-1; EC to balling romaine lettuce and red clover
50value is respectively 0.1297g.L
