Description
Technical field
The present invention relates to herbicide technology fields, and in particular to a kind of clomazone herbicide particle and preparation method thereof.
Background technique
Clomazone is considered as high volatility.When it is applied in the soil of target area, in certain conditions
Under, clomazone is transportable or is diffused into adjacent region, cause useful plants albefaction near processed field or
Bleaching.Although this albefaction and bleaching occur in non-targeted plant, the binding mode of clomazone shows to be exposed to when plant
This albefaction and bleaching may be temporary when in sufficiently low concentration, but this is unwelcome, even if it is without result in plant
The destruction of object.
The microencapsulated formulation of clomazone has been developed to solve the volatility problem of clomazone.By proposing one kind
The low volatility preparation of clomazone solves the high volatile of clomazone, wherein making clomazone micro-capsule in polyurea shell
Change.However, existing clomazone microencapsulated formulation is by its accessible clomazone concentration and there may be other activity
The limitation of composition preparation of microencapsulation together with clomazone.In addition, the capsule of clomazone micro-capsule and other pestsides synthesis suspends
Preparation is usually chemically or physically unstable.In addition, the weight of the commercial suspension liquid of clomazone micro-capsule is very big by one
Part is inactive ingredient.The high level inert component present in commercial herbicide increases the volume and weight of herbicide,
Lead to additional production cost, packing cost, transportation cost, storage cost, processing cost and other and manufacture, transport, storage
Deposit and use the relevant cost of herbicide.The other shortcomings of liquid preparation include being difficult to protect when being stored in cold or hot condition
Hold the stability of preparation.
Herbicide is limited by crop safety at present, and degrass spectrum is also limited, and a kind of herbicide single dose is used alone cannot be complete
The generation of field weed is efficiently controlled entirely, furthermore some herbicides are since the water-soluble big or field lasting period is too long, dosage is excessive
Or application unevenly all be easy to cause residual hazard to this season crop or succession crop, inventor it has been investigated that, herbicide
Synergistic complex be expand weed control spectrum and improve preventive effect effective measures.
Chinese patent CN106889083B discloses a kind of Herbicidal combinations containing pyraclonil and clomazone and its answers
With the Herbicidal combinations are using pyraclonil and clomazone as principle active component, the mass ratio of clomazone and pyraclonil
For 1:60~60:1.Herbicidal combinations of the present invention can be used for weeding before Soybean Field bud, especially for preventing and kill off Soybean Field Tanaka's standing grain
Undergraduate course and broadleaf weeds have remarkable result.Herbicidal combinations of the present invention under the premise of improving drug effect, prolong compared to single agent
Slow Weed Resistance, herbicidal spectrum is wide, and the lasting period is long, and all has safety to soybean and succession crop.But the invention system
Standby Herbicidal combinations are single carry out weeding, can not promote to grow to plant.
In conclusion developing, a kind of not volatile, easy storage, low cost, activity of weeding be high, highly-safe different evil
Humulone herbicide particle and preparation method thereof is those skilled in the art's urgent problem.
Summary of the invention
The object of the present invention is to provide a kind of clomazone herbicide particles and preparation method thereof, solve clomazone and remove
Careless agent particle it is volatile, be not easy to store, the problems such as at high cost, activity of weeding is bad, safety is poor.
To solve the above problems, the invention provides the following technical scheme: a kind of clomazone herbicide particle and its preparation
Method:
Prepare the raw material and its parts by weight of clomazone herbicide particle are as follows: 35 parts~50 parts of plant ash, clomazone 20
Part~30 parts, 3 parts~5 parts of pyraclonil, 2.6 parts~3.8 parts of isopropyl methoxalamine, 5 parts~8 parts of polyvinyl alcohol, 3 parts of paclobutrazol
~6 parts, 4 parts~10 parts of diatomite, 15 parts~19 parts of urea, 6 parts~10 parts of potassium dihydrogen phosphate, 4 parts~8 parts of gibberellin, grass is sweet
1 part~3 parts of phosphine composition, 2 parts~5 parts of aluminium-magnesium silicate, 1.6 parts~1.9 parts of sodium carboxymethylcellulose, 1 part~3 parts of castor oil,
4 parts~7 parts of aluminum phosphate, 10 parts~12 parts of water.
Further, clomazone purity is 78%.
Further, the preparation process of glyphosate composition are as follows: by diesel oil, glyphosate, washing powder temperature be 30 DEG C~
It is mixed under the conditions of 40 DEG C, obtains glyphosate composition.
Washing powder and diesel oil are added in glyphosate can enhance spread, permeability and the adhesion strength of drug, improve anti-
Effect.
Further, diesel oil, glyphosate, washing powder volume ratio be 1:3:0.5.
Further, incorporation time is 20min~40min.
Another object of the present invention is to provide a kind of above-mentioned preparation method of clomazone herbicide particle, preparation steps
It is rapid as follows:
Step S1, by the urea of the parts by weight, potassium dihydrogen phosphate, polyvinyl alcohol, aluminium-magnesium silicate, carboxymethyl cellulose
Extruding pelletization after sodium, castor oil, aluminum phosphate, diatomite, water stirring, obtains A material；
Step S2, the resulting A material of step S1 is put into granulating disc will after A is expected moistened surface by penetrating atomized water
Paclobutrazol, the gibberellin of the parts by weight are added in disk, rotating circular disc, and paclobutrazol, gibberellin are wrapped in A material surface, obtained
To kernel；
Step S3 will be sprayed on core surface obtained by step S2 after the pyraclonil of the parts by weight, isopropyl methoxalamine atomization,
The 1/4~1/2 of the plant ash of the parts by weight and glyphosate composition are put into granulating disc, rotating circular disc is allowed to
It is wrapped in kernel outer layer, the clomazone of the parts by weight is atomized, is sprayed onto kernel outer layer, then remaining plant ash is added to circle
In disk pelletizer, rotating circular disc 30 times~50 times, so that plant ash is all wrapped in outer layer, obtain pre-treated particles；
Step S4, pre-treated particles obtained by step S3 are dry, obtain clomazone herbicide particle.
Further, in step S1, extrusion temperature is 50 DEG C~60 DEG C.
Further, in step S3, the diameter of pre-treated particles is 4mm~5mm.
Further, in step S4, drying process is divided to two sections of progress, and first segment is under the conditions of temperature is 20 DEG C~30 DEG C
Dry 10min~15min, second segment dry 20min~40min under the conditions of temperature is 30 DEG C~50 DEG C.
Further, after dry, the water content of clomazone herbicide particle is 6%.
It can be seen from above-mentioned technical proposal the invention has the following advantages:
(1) clomazone herbicide particle selection degrass spectrum prepared by the present invention is different, the pyraclonil of advantage and disadvantage complementation
With two kinds of herbicides of clomazone, it is made into Herbicidal combinations of the invention according to specific ratio range, two kinds of differences can be passed through
Mechanism kills weeds, and two kinds of herbicides generate synergistic effect in the ratio range, greatly improve the removing activity of herbicide；
(2) clomazone herbicide particle prepared by the present invention can prevent and treat a variety of weeds simultaneously, provide a kind of extremely square
Just effectively preventing means, broadleaf weeds and gramineae weed to the crop fields such as corn, beet, sugarcane and orchard etc. have good
Good preventive effect；
(3) clomazone herbicide particle prepared by the present invention is solid particle, can effectively prevent volatility, improve
Drug effect, and after herbicide plays pharmacological property weeding, gibberellin, paclobutrazol can promote plant strain growth, improve yield；
(4) composition pesticide compounds performance within a certain ratio range in clomazone herbicide particle prepared by the present invention
Fabulous synergistic effect out, significantly improves herbicidal effect compared with single dose, to reduce usage amount, is reducing peasant's medication
While cost, the influence to environment is reduced.
