Test method: the greenhouse pot culture method is adopted in test, the quantitative weed seed of sowing in Disposable paper cup, treat that the unearthed back of weeds 1.5～2 leaves carry out thinning during the phase, each dixie cup is cultivated by the more consistent weeds plant of 5 strain growing ways of selecting and remain, and regularly water N, P, the aqueous solution of K composite fertilizer, treat 4～6 leaf phases of broad leaved weed, grassy weed grows to 2～5 leaves during the phase, carrying out the cauline leaf spraying with crawler type crop sprayer handles, each processed group dosing (being the effective active dose of components) is as shown in table 1, handle and be placed on greenhouse continuation cultivation observation, the herbicidal effect of each processing of " Invest, Then Investigate " in 20 days after back 3 hours.The result is as shown in table 1.
Table 1 mesotrione, dicamba, diflufenzopyr and the present composition are to the preventive effect of broad leaved weed and grassy weed
As can be seen from Table 1, mesotrione, dicamba and more single with comparing after diflufenzopyr is composite, to weeds particularly the preventive effect of broad leaved weeds such as Commelina communis, the root of Beijing euphorbia etc. be significantly improved, grass family class weeds such as barnyard grass grass also there are obvious synergistic effect, reach the purpose of preventing and kill off broad leaved weed and grassy weed simultaneously.
Though above the present invention is described in detail with a general description of the specific embodiments, on basis of the present invention, can make some modifications or improvements it, this will be apparent to those skilled in the art.Therefore, these modifications or improvements all belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
