Description

A kind of herbicide for paddy field and its application and preparation method
Technical field
The present invention relates to herbicide technology field, more particularly to a kind of herbicide for paddy field and its application and preparation method.
Background technology
One of paddy rice is not only the main cereal crops of China, and world's staple food crop.Nearly half in the world Population, including the population in almost whole East Asia and Southeast Asia, all with rice as food.Production is throughout each continent in addition to the South Pole. Eighties of last century late period, 400,000,000,000 kilograms or so of View of World Rice annual production average out to, about 1.45 hundred million hectares of cultivated area.China paddy rice Sown area accounts for the 1/4 of national cereal crops, and every year about at more than 3,500 ten thousand hectares, and yield then accounts for more than half.No matter plant Area and yield, paddy rice all rank first in China cereal crops.
In production management process, weeding is a main task to paddy rice.Weeds strive fertilizer with paddy rice and win honour for, and have a strong impact on water The growth of rice, reduces rice yield.Medium crop smothering area accounts for more than the 46% of total cultivated area, wherein serious injured area exists More than 11.5%, more than 200 hundred million kilograms of grain is thus lost every year.Therefore, the use ratio of domestic herbicide for paddy field is nearly reached 100%, its dosage is very big.With the development of agricultural cience and farming techniques, the popularization and application of chemical herbicide as saving of labor, Save time, one of cost-effective strong well stimulation.
As herbicide is developed rapidly, the appearance of numerous new varieties creates diversified novel form.A kind of active compound is put down It has been intended to more than 10 kind processing formulations.The sorting technique of formulation is that formulation of herbicide is divided into solid pharmaceutical preparation and liquid by the states of matter of preparation Two class of body preparation；Missible oil, suspending agent, aqueous emulsion can be divided into by type of dosage form（Emulsifiable concentrate）, microemulsion, wettable powder and water Dispersible granule etc..
In actual production management, herbicide mainly carries out dispenser with sprayer by artificial.As cost of labor is got over Come higher, labour's majority is gone down town and worked in rural area, therefore rice herbicide dispenser is increasingly difficult to.Be badly in need of one kind can simplicity apply The novel form of medicine.
The content of the invention

Find out from application test example 1, pretilachlor and Oxadiargyl waxy composition, it is when rice terrace closes weeding, single Component pretilachlor integrated control effect 34.5%, Oxadiargyl integrated control effect 19.6%.Pretilachlor, Oxadiargyl water dispersible granules are comprehensive It is 68.9% to close preventive effect, and the integrated control effect of composition is 78.2～90.0%, and synergistic effect is clearly.Waxy composition exists simultaneously It is very convenient during dispenser, saving of work and time.
Find out from application test example 2, pretilachlor and anilofos waxy composition, when rice terrace closes weeding, one pack system Pretilachlor integrated control effect 8.0%, Sha's spy's phosphorus integrated control effect 29.6%.Pretilachlor is 51.0% with anilofos missible oil integrated control effect.Combination The integrated control effect of thing is 61.2～83.5%, and synergistic effect is clearly.Waxy composition is very convenient in dispenser simultaneously, saves Work saves time.
Find out from application test example 3, pretilachlor and Oxyfluorfen, humulone waxy composition, remove in rice terrace closing When careless, one pack system pretilachlor integrated control effect 44.5%, Oxyfluorfen integrated control effect 34.4%, humulone integrated control effect 41.8%.Third Careless amine is 77.7% with the integrated control effect of Oxyfluorfen, humulone missible oil.The integrated control effect of composition is 88.7～99.4%, is increased Effect is acted on clearly.Waxy composition is very convenient in dispenser simultaneously, saving of work and time.
Find out from application test example 4, pretilachlor and symetryne waxy composition, when rice terrace closes weeding, one pack system Pretilachlor integrated control effect 38.3%, symetryne integrated control effect 39.7%.Pretilachlor with the integrated control effect of symetryne wettable powder is 59.8%.The integrated control effect of composition is 78.5～90.0%, and synergistic effect is clearly.Waxy composition is non-in dispenser simultaneously It is often convenient, saving of work and time.
Find out from application test example 5, pretilachlor and humulone waxy composition, when rice terrace closes weeding, one pack system Pretilachlor integrated control effect 45.9%, symetryne integrated control effect 44.7%.Pretilachlor is 72.7% with the integrated control effect of humulone missible oil. The integrated control effect of composition is 78.2～99.7%, and synergistic effect is clearly.Waxy composition is very square in dispenser simultaneously Just, saving of work and time.
As can be seen here, the prevention effect of wax stone shape herbicidal composition of the invention is significantly improved, and synergy is notable.Exist simultaneously Spraying need not be watered during administration, directly can be spread fertilizer over the fields, very easy to use, saving of work and time.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
