Description
Technical field
The present invention relates to agriculture field, particularly, relate to the purposes of a kind of herbicidal composition and this herbicidal composition.
Background technology
Paddy rice is one of China's staple food crop, accounts for 29% of plant of grain crops area.
According to statistics, crop smothering rice area accounts for more than 46% of total cultivated area, so weeds and paddy rice strive water, strive fertilizer, is one of principal element affecting rice yield, if do not prevented and not treated, can causes a large amount of underproduction.
Weeds in paddy field are mainly divided three classes: grassy weed: barnyard grass, Paspalum distichum; Broad leaved weed: angustifolia arrowhead herb, Monochoria korsakowii, pondweed, rhizoma alismatis, wolf tail grass, alternanthera philoxeroides; Sedge weed: difformed galingale herb, flat stalk Fischer grass, Japanese Fischer grass, firefly Lin (little Scirpus tabernaemontani), fescue; In addition weeds are under water also had: little najas marina, pipewort etc.
At present, prevent and kill off paddy field weed major herbicides kind to have: butachlor, Acetochlor, the third careless amine, bensulfuron-methyl, Stam F-34 etc., but due to the difference of chemical composition, formation and physic-chemical property, the herbicide of different weed killer herbicide is limited in one's ability and herbicide spectrum is narrower, such as, butachlor is tooth pro-herbicide, when during dispenser, water layer floods lobus cardiacus, butachlor liquid is had an impact to paddy growth point, easily produces symptom of chemical damage; Acetochlor weed killer herbicide is to grassy weed weak effect, and in surface water, Acetochlor metabolite has certain harm to human body; When third careless amine is used separately, poor to wet slotting rice selective, and paddy rice germination period is also more responsive to the third careless amine; Bensulfuron-methyl is to barnyard grass weak effect, and the rice seedling bed based on barnyard grass should not use; Stam F-34 is the contact killing type weed killer herbicide of amide-type high selectivity, but easily decomposes in soil, can not make processing soil treatment agent and use.
Due to the existing weed killer herbicide of Long-Time Service, resistance weed strengthens gradually, causes existing weed killer herbicide to there is the poor defect of control efficiency.
Summary of the invention
The object of the invention is to overcome the poor defect of weed killer herbicide control efficiency, provide a kind of control efficiency good herbicidal composition.
To achieve these goals, the invention provides a kind of herbicidal composition, this herbicidal composition contains flumioxazin and the third careless amine; Relative to the flumioxazin of 1 weight portion, the content of the third careless amine is 0.15-500 weight portion.
Present invention also offers the purposes of herbicidal composition as above in water prevention weeds in paddy field.
By technique scheme, herbicidal composition of the present invention, relative to flumioxazin and the third careless amine, can obtain and obviously strengthen ground control efficiency, thus improve the control efficiency of weed killer herbicide.
Other features and advantages of the present invention are described in detail in embodiment part subsequently.

At the herbicidal composition of Rice Cropping field build-in test embodiment 1-13 and comparative example 1-5 to the control efficiency of weeds, concrete steps comprise: transplanting rice, after 6 days, mixes the herbicidal composition that soil spreads fertilizer over the fields embodiment 1-13 and comparative example 1-5 in different growing areas.Wherein, the amount of application of the herbicidal composition of embodiment 1-7 and comparative example 1-5 is 100g/ mu, the amount of application of the herbicidal composition of embodiment 8 is 100g/ mu, the amount of application of the herbicidal composition of embodiment 9 is 83.3g/ mu, the amount of application of the herbicidal composition of embodiment 10 is 66.7g/ mu, the amount of application of the herbicidal composition of embodiment 11 is 200g/ mu, the amount of application of the herbicidal composition of embodiment 12 is 400g/ mu, and the amount of application of the herbicidal composition of embodiment 13 is 400g/ mu.The area testing the growing area of often kind of herbicidal composition is 5 mu, mix soil with weed killer herbicide when using, carry out medicine soil and spread fertilizer over the fields, and substitute weed killer herbicide as space management using water, use except weed killer herbicide except by such scheme, other planting conditions of each growing area is identical.Spread fertilizer over the fields weed killer herbicide after 30 days, carry out identification counting to the weeds of growing area, calculate strain preventive effect by formula (A), and add up the rice yield of growing area, result is as shown in table 1.
Table 1
As can be seen from Table 1, herbicidal composition of the present invention, due to its distinctive composition and combination, has obviously synergistic effect, can obtain the effect of high-efficiency environment friendly ground controlling weeds, thus improve the output of paddy rice relative to the combination of other composition and consumption.
In addition, as can also be seen from Table 1, herbicidal composition of the present invention is at the flumioxazin relative to 1 weight portion, the content of the third careless amine is under the preferable case of 1.5-100 weight portion, and particularly at the flumioxazin relative to 1 weight portion, the content of the third careless amine is under the preferable case of 10-30 weight portion, more excellent control efficiency can be obtained, and can dosage be reduced, cost-saving, alleviate the pollution to environment and raising rice yield.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible combination.
In addition, also can be combined between various different embodiment of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
