Abstract

A composite herbicide contains sulcotrine-methyl and one of 18 herbicide including propisochlor, acetochlor, atrazine, etc.

Description

A kind of Herbicidal combinations that contains mesotrione
Technical field:
The present invention relates to contain the binary built Herbicidal combinations of mesotrione, be mainly used in cornfield weeding.
Background technology:
At present China's corn field herbicide mainly contains the A Yi mixture of using before the seedling (atrazine+Acetochlor), use behind the seedling 2,4-D butyl ester, dicamba, Brominal, beautiful farming are happy etc.Because the longevity of residure of atrazine in soil is longer, be unfavorable for crop rotation, not only influence back stubble is planted brassicaceous vegetable, and to afterwards stubble is planted wheat, soybean also can produce poisoning, and it is bigger that the herbicidal effect of the weed killer herbicide of soil treatment is influenced by soil moisture, drug effect is relatively poor when arid, even invalid; And cauline leaf handles in the weed killer herbicide 2, and 4-D butyl ester, dicamba, Brominal etc. only have preventive effect preferably to broad leaved weed, and are invalid to grassy weed; Cauline leaf inorganic agent nicosulfuron all has preventive effect preferably to broad leaved weed and grassy weed, but higher because of its cost, and influences its large-area applying.
Mesotrione is a kind of novel three ketones weed killer herbicide, but both native list processings before the seedling, but also cauline leaf spraying behind the seedling, instant effect simultaneously, simultaneously mesotrione residual life in soil short, so to succession crop safety.Simultaneously, its biologically active surpasses the sulphur humulone more than 10 times, has more potentiality to be exploited with competitive, because it is environmentally friendly, calendar year 2001 sells in the EU countries and the U.S. in 2002 by the approval of Environmental Protection Agency USA.But its control efficiency to broad leaved weed common in the corn field such as Siberian cocklebur, Tong fiber crops, japanese bearbind, acalypha copperleaf etc. is not very good.In addition, the domestic and international composition of also not mentioned it and other specific compounds of patent.Therefore it is unforeseen with the effect of other compound use.
Summary of the invention:
The stack that effectiveness that Herbicidal combinations was showed that mesotrione and compound that some is specific are formed with certain proportion among the present invention and activity level have exceeded individual composition activity, this exercising result is called synergistic effect.The invention provides the one group of compound that has synergistic effect with mesotrione, in the hope of a kind of efficient, low-residual of further invention, low cost and grassy weed and broad leaved weed all there are the disposable herbicide composition of better preventive effect, they can enlarge kills the grass spectrum, improves herbicidal effect, reduces residual activity, reduces poisoning to crop, delays the drug-fast generation of weeds and the succession of community, reduction dosage, reduces environmental pollution, laborsaving simultaneously, economical, reduce farmer's burdens.
The binary mixture preparation of preventing and kill off corn field weed that mesotrione and weed killer herbicide M form is mainly used in corn field, is pesticidal preparations.The active ingredient weed killer herbicide M that the present invention relates to is respectively:

The purpose of this invention is to provide and a kind ofly be applicable to that single broadleaf weed prevents and kill off, to the binary mixture preparation that contains the methyl yellow humulone when stubble corn and succession crop safety.
Herbicide formulations of the present invention is to be the binary mixture of active ingredient by mesotrione and weed killer herbicide M, be mainly used in the disposable single broadleaf weed that corn field takes place of preventing and kill off, the active ingredient that contains in this mixture is respectively sulphur humulone: M=1: 30-50: 1, add an amount of auxiliary agent or carrier, can be processed into the dispersibility granula, do outstanding agent, aqua, suspending agent, wetting powder, missible oil, sustained release agent, granule.
The present invention is to be the binary mixture and the application thereof of active ingredient by mesotrione and weed killer herbicide M, and advantage is
1, easy to use.Composition proposed by the invention can seedling pre-treatment (closed soil treatment) but also behind the seedling cauline leaf spraying handle, use optimum period long, the user can freely select spraying time according to environmental condition.
2, broad weed-killing spectrum.One of the composition that the present invention proposes mesotrione list is used most of lists dicotyledonous all effective, after using with other weed killer herbicides M, not only can effectively kill the weeds after being unearthed, and also the weeds of not being unearthed in the controlled soil are improved herbicidal effect.
3, save drug cost.The composition that the present invention proposes, can disposablely prevent and kill off the single broadleaf weed after great majority are emerged in the corn field, and the weeds that do not sprout as yet in the soil, the weeds of dispenser controlled corn field in most of breeding times, saved half farming season of user, relatively happy with the beautiful farming of corn field herbicide after seedling simultaneously, the mu cost is from 15-20 unit/mu, drop to 3-8 unit/mu, saved drug cost greatly.
4, to working as stubble corn and succession crop safety.The composition that the present invention proposes is through verification experimental verification, not only to when the safety of stubble crop corn fine, and after the medication 3 months, to the equal safety of crops such as the soybean of back stubble plantation, paddy rice, rape, Chinese sorghum, wheat.Illustrate that the said composition lasting period can reach three months, just in time control weeds harm in the corn growth stage, also can not influence succession crop simultaneously, solved heterocycle herbicides such as use atrazine, change the problem of stubble difficulty.
