Description
Technical field
The present invention relates to agriculture field, particularly, relate to a kind of herbicidal composition, and the purposes of this herbicidal composition.
Background technology
Rape is the most important oil crop of China, since 1985, China's rapeseed cultivation area and first place, the equal world of gross yield, account for 30% left and right of world's rapeseed cultivation area and gross yield, in international rape industry, occupy space of prominence, simultaneously the main source of rape Ye Shi China edible vegetable oil.
The diversified impact of various places climate, environment and planting type, rape field weed is relatively complicated, and weeds harm is serious, and difficulty of prevention and cure is large.In recent years, rape field weed kind constantly rises, and because itself and crop strive fertilizer, strive water, strive sunlight, strive space etc., yield of rape and quality is caused to serious impact, therefore become Rapeseed Field produce in problem demanding prompt solution.
According to the careless phase between Rapeseed Field, the weeds type between China's Rapeseed Field is broadly divided into: taking grassy weed as main, be mainly amur foxtail, wild oat etc.; Taking broad leaved weed as main, be mainly clearvers, ox chickweed, shepherd's purse etc.; Grass family and broad leaved weed are mixed raw, are mainly the mixed lifes such as clearvers, ox chickweed and amur foxtail.
At present, the main weed killer herbicide kind of Controlling Weeds in Rape Fields field grassy weed has amide-type processing soil treatment agent Acetochlor, alachlor etc.; Cauline leaf inorganic agent has the fragrant phenoxy base propionic acid ester diclofop-methyl of (being called for short AOPP), haloxyfop-r-methyl, efficient fluazifop, Quizalotop-ethyl etc.; The sethoxydim of cyclohexenone analog (being called for short CHD) etc.AOPP and CHD class weed killer herbicide are the leading medicaments that Rapeseed Field is prevented and kill off grassy weed always, wherein haloxyfop-r-methyl uses more extensive at middle and lower reach of Yangtze River Paddy field after rice, due to long-term this weed killer herbicide of single use, playing annual medication number of times and dosage is all increasing gradually, weed killer herbicide constantly rises to weeds selectivity, and drug effect constantly declines.And control broad leaved weed aspect, conventional product only has several medicaments few in number such as benazolin, ethametsulfuron at present.Wherein ethametsulfuron is because degradation speed is slow, and on the residual impact of paddy rice of rear stubble and in the south of the River, forbid in most of province, and grass eliminates the limitation due to its herbicidal spectrum aspect, and through long-term use in a few years, some variations have occurred weeds in field grass mutually.
Due to a large amount of generations of Rapeseed Field resistant weed, there is the defect that preventive effect is lower in current weed killer herbicide in the time of control Rapeseed Field resistant weed.
Summary of the invention
The lower defect of usefulness that the object of the invention is to overcome weed killer herbicide, provides the herbicidal composition that a kind of usefulness is higher.
To achieve these goals, the invention provides a kind of herbicidal composition; This herbicidal composition contains clethodim, clopyralid and picloram; With respect to the clethodim of 1 weight portion, the content of clopyralid is 0.01-90 weight portion, and the content of picloram is 0.005-45 weight portion.

Test implementation example 1
This test implementation example is tested the control efficiency of amur foxtail, wild oat, clearvers, ox chickweed and barnyard grass.
Control efficiency at the herbicidal composition of rapeseed cultivation field build-in test embodiment 1-12 and comparative example 1-9 to weeds, concrete steps comprise: after rape seed 3 days, use the herbicidal composition of embodiment 1-12 and comparative example 1-9 at different growing area internal sprayings.Wherein, the amount of application of the herbicidal composition of embodiment 1-7 and comparative example 1-9 is 100g/ mu, the amount of application of the herbicidal composition of embodiment 8 is 29g/ mu, the amount of application of the herbicidal composition of embodiment 9 is 33.3g/ mu, the amount of application of the herbicidal composition of embodiment 10 is 50g/ mu, the amount of application of the herbicidal composition of embodiment 11 is 66.7g/ mu, and the amount of application of the herbicidal composition of embodiment 12 is 200g/ mu.The area of testing the growing area of every kind of herbicidal composition is 5 mu, while using, being diluted with water to every mu of spray amount is 30L, and substitute herbicidal composition as space management using water, except using weed killer herbicide by such scheme, other planting conditions of each growing area is identical.After spraying herbicide 20 days, the weeds of growing area are identified to counting, calculate strain preventive effect, and the rape seed output of growing area is added up by formula (A), result is as shown in table 1.
Formula (A)
Table 1
As can be seen from Table 1, herbicidal composition of the present invention, due to its distinctive composition and combination, has very notable synergistic effect, can obtain the effect of high-efficiency environment friendly ground controlling weeds with respect to the combination of other composition and consumption, thereby improves the output of rape seed.
In addition, as can also be seen from Table 1, herbicidal composition of the present invention is at the preferred clethodim with respect to 1 weight portion, the content of clopyralid is 0.1-5 weight portion, the content of picloram is in the situation of 0.01-1.5 weight portion, particularly at the preferred clethodim with respect to 1 weight portion, the content of clopyralid is 0.5-1.5 weight portion, the content of picloram is in the situation of 0.05-0.35 weight portion, can obtain more excellent control efficiency, and can reduce dosage, cost-saving, alleviate the pollution to environment and improve corn 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 characterictic described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present invention, also can be combined, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
