Description
Technical field
The present invention relates to paddy field weed prevention and control fields, especially a kind of for the granula of agent for removing grass in paddy field and its preparation side
Method.
Background technique
Usually there are many dosage forms, such as wettable powder, missible oil, aqua, water to dissipate for herbicide used in rice field at present
Granula, suspending agent etc., however these dosage forms had using the shortcomings that difficult, the amount of labour is big, low efficiency.When application need mix soil,
It mixes fertilizer to spread fertilizer over the fields or water spray is added to walk using and field, time-consuming, large labor intensity.And wettable powder is in application
Dust drift is had, can user or environment be caused damages or be polluted.
In recent years, from the point of view of the burden increase of the aging of peasant, part-timeization and woman worker, need to save application agrochemicals
The labour of product.It is therefore not necessary to the use of any mechanical and the reduction manpower without coming into paddy field applications of pesticide method be very
Welcome.On the other hand, the concern influenced due to society on Pesticide environment is higher and higher, is sought after easily applying
Pesticidal preparations are to reduce risk that pesticide is lost from Tanaka and reduce the harm to operator.
In this case, the exploitation of granule becomes to adapt to very much current situation at present, this is because its is advantageous
Characteristic, it is convenient without going to the field such as to apply, time saving and energy saving ultrahigh in efficiency, without dust drift to operator and Environmental security, application
When influenced the risk that smaller, pesticide is lost from spray by weather and reduced etc..Although effervescent tablet also has the advantages of Labor-saving,
But the risks such as swollen bag, failure are generated because acid-base neutralization reaction occurs for its moisture-sensitive, thus application is extremely limited, and particle
Agent does not have the risk of this respect.To sum up, granule combines the excellent dispersibility of missible oil, wettable powder storing conveniently and does outstanding
Floating agent advantage easy to use, has the advantages that full field is spread automatically, significantly reduces labor intensity, and environmental pollution
Small, formulation rate is easily mastered, and climate Effects of Factors is small, has apparent application value.
Summary of the invention
In view of this, the granula and preparation method thereof that the object of the present invention is to provide a kind of for agent for removing grass in paddy field, is made
