Abstract
The invention provides a herbicide composition, comprising the following active ingredients by weight: 0.1-5 parts of mesotrione, 0.1-10 parts of fluroxypyr and 0.1-10 parts of diflufenzopyr. The invention also provides application of the herbicide composition to controlling annual and perennial broadleaf weeds and grass weeds in the corn fields. The herbicide composition obviously improves the weed control effect compared with the single agent, has excellent synergy, reduces the drug dosage, reduces the impact on the environment while lowering the drug cost of the farmers, simultaneously expands the weed control spectrum and can effectively retard occurrence and development of the tolerance of the single angle.
Description
Technical field
The present invention relates to the agricultural herbicide field, specifically, relate to a kind of herbicidal composition and application thereof that contains mesotrione, fluroxypyr, three kinds of active components of diflufenzopyr.
Background technology
Mesotrione is an all spendable broad-spectrum herbicide before the seedling, behind the seedling, it is to two oxidase (HPPD) inhibitor of hydroxyphenyl pyruvic acid, three ketones weed killer herbicide by the exploitation of the sharp Kanggong of victory department, can effectively prevent and kill off annual gramineous weed and most of broad leaved weed, especially the weeds effect to sulfonylurea herbicide generation resistance is obvious.
Fluroxypyr is the inner sucting conduction type weed killer herbicide, and is very fast by plant absorbing after the medication, makes sensitive plant the reaction of typical hormone herbicide occur, and the plant deformity is twisted.Temperature does not have influence to the final effect of its weeding, but influences the speed of its drug effect performance.General when temperature is low the drug effect performance slower, stop growing, but dead immediately the temperature back plant death immediately that raises after can making dunsiekte.
Diflufenzopyr belongs to the pyridines weed killer herbicide, be the growth hormone transfer inhibitor,, be mainly used to control of maize Tanaka's broad leaved weed and grassy weed by BASF AG's exploitation, it can make plant growing deformity, depleted of energy and death, has characteristics such as low toxicity, efficient, low-residual.

In the greenhouse, adopt potted plant method to measure the preventive effect of composite preparation to broad leaved weed and grassy weed.
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, fluroxypyr and 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, fluroxypyr and more single with comparing after diflufenzopyr is composite, to weeds particularly the preventive effect of broad leaved weeds such as dayflower, 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.
