Description
Technical field
The invention belongs to technical field of pesticide, more particularly to a kind of agricultural chemicals for preventing and treating crop fungi and bacterial disease
And its prepare.
Background technology
In flowers, fruit tree, rape, vegetables or field crop, powdery mildew, gray mold, rice blast, it is various rot
The fungal diseases such as disease, brown rot and root rot and bacterial disease are very weighed so that crop failure even has no harvest.Current majority
Agricultural chemicals cannot meet requirement of the country to remaining, and cause environmental pollution.And multicomponent is single, drug effect is not enough, easily makes to fall ill
Evil develops immunity to drugs, and permanence operation is not good.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide it is a kind of for prevent and treat crop fungi and
The agricultural chemicals of bacterial disease and its preparation, can be configured to water dispersible granules, wettable powder, suspending agent for agriculturally allowing etc.,
There is good result to preventing and treating such disease.
To achieve these goals, the technical solution used in the present invention is：
A kind of agricultural chemicals for preventing and treating crop fungi and bacterial disease, including the Boscalid of mass fraction 1%～80%,
And acceptable auxiliary combination on agricultural chemicals.
When the auxiliary combination is dispersant, wetting agent, disintegrant and binding agent, each component accounts for quality percentage in agricultural chemicals
Than for：Boscalid 1%～80%, dispersant 3～12%, wetting agent 2～8%, disintegrant 0～8%, binding agent 0.001～5%, it is remaining
Measure as filler, now the agricultural chemicals is water dispersible granules.
Invention also provides preparing the agricultural chemicals for preventing and treating crop fungi and bacterial disease（Water-dispersible grain
Agent, single dose）Method, in proportion by other components in addition to bonding agent together Jing air-flow crushings obtain need particle diameter, then add
Enter binding agent, obtain materials of pelletizing, granulation is sent in fluidized bed granulating dryer after granulation and drying i.e. with materials quantitative
.
When the auxiliary combination is dispersant, wetting agent, defoamer, thickener and antifreezing agent, each component is accounted in agricultural chemicals
Mass percent is：Boscalid 1%～80%, dispersant 3～12%, wetting agent 2～10%, defoamer 0.1～0.5%, thickener
0～2%, antifreezing agent 0～8%, balance of deionized water, now the agricultural chemicals is suspending agent.
Invention also provides preparing the agricultural chemicals for preventing and treating crop fungi and bacterial disease（Suspending agent, it is single
Agent）Method, it is in proportion that dispersant, wetting agent, defoamer, thickener and antifreezing agent is uniform through shear-mixed, add
Boscalid, ball milling 2～3 hours in ball mill make diameter of particle all obtain final product below 5 μm.
When the auxiliary combination is dispersant and wetting agent, each component accounts for mass percent and is in agricultural chemicals：Boscalid
1%～80%, dispersant 3～15%, wetting agent 2～12%, balance of filler, now the agricultural chemicals is wettable powder.
Invention also provides preparing the agricultural chemicals for preventing and treating crop fungi and bacterial disease（Wettable powder
Agent, single dose）Method, in proportion by Boscalid, dispersant, wetting agent, filler mixing, be well mixed in mixed cylinder, Jing
Airslide disintegrating mill is remixed after crushing and uniformly obtained final product.
When the auxiliary combination is emulsifying agent, antifreezing agent and defoamer, each component accounts for mass percent and is in agricultural chemicals：Pyridine
Acyl bacterium amine 1%～80%, emulsifying agent 5～15%, antifreezing agent 0～8%, defoamer 0.1～0.5%, balance of solvent, the now agriculture
Medicine is microemulsion.
Invention also provides preparing the agricultural chemicals for preventing and treating crop fungi and bacterial disease（Microemulsion, it is single
Agent）Method, in proportion by Boscalid, emulsifying agent, antifreezing agent, defoamer, solvent mixing, in mixed cylinder mix glue stick it is equal
It is even to obtain final product.
Another kind of form of the present invention, a kind of agricultural chemicals for preventing and treating crop fungi and bacterial disease, using compounding system
Agent, including：Mass ratio is 25：Acceptable auxiliary combination on 5 Boscalid and pyraclostrobin, and agricultural chemicals.
When the auxiliary combination is dispersant and wetting agent, each component accounts for mass percent and is in agricultural chemicals：Boscalid
25%th, pyraclostrobin 5%, dispersant 5%, wetting agent 5%, balance of filler, now the agricultural chemicals is wettable powder.
When the auxiliary combination is wetting agent, dispersant, disintegrant, defoamer and binding agent, each component is accounted in agricultural chemicals
Mass percent is：Boscalid 25%, pyraclostrobin 5%, wetting agent 5%, dispersant 5%, disintegrant 2%, defoamer 0.5%,
Binding agent 0.5%, balance of filler, now the agricultural chemicals is water dispersible granules.
It is each in agricultural chemicals when the auxiliary combination is dispersant, wetting agent, thickener, antifreezing agent, defoamer and preservative
Component accounts for mass percent：It is Boscalid 25%, pyraclostrobin 5%, dispersant 5%, wetting agent 5%, thickener 0.5%, antifreeze
Agent 3%, defoamer 0.3%, preservative 0.2%, balance of deionized water, now the agricultural chemicals is suspending agent.
The preparation method of complex preparation is consistent with the single dose preparation process of respective type.
The above dispersant may be selected dodecyl sodium naphthalene sulfonate（NNO）Or sodium methylene bis-naphthalene sulfonate, wetting agent can
Select lauryl sodium sulfate or dodecyl sodium sulfate, defoamer that polysiloxanes or organosilicon may be selected, thickener may be selected
