Description

A kind of Herbicidal combinations

It is on 06 05th, 2013, invention name that the present invention, which is China national application No. is the 201310220249.9, applying date, A kind of referred to as divisional application of the application for a patent for invention of " Herbicidal combinations ".

Technical field

The present invention relates to a kind of Herbicidal combinations more particularly to a kind of removing containing promazine Sulfometuron Methyl and cyhalofop-butyl Careless composition and application thereof and corresponding weed control methods.

Background technology

Currently, in order to promote the growth quality of crop, constantly it is dedicated to developing herbicidal effect height in industry, has widely The excellent herbicide of herbicide controlling spectrum, low toxicity, low-residual, crop-selective.In the production environment of crop, certain weedings are used for a long time Agent can cause certain weeds to generate certain resistance to corresponding drug.So far, many kinds of sulfonyl urea compounds are real Border is used for rice field, is usually widely used that composite preparation form, in preparation containing two or more active constituents and for Prevent grassy weed effectively miscellaneous grassy weed killing agent.But in recent years, occur to sulfonylurea herbicide (such as bensulfuron-methyl, pyrazosulfuron and flazasulfuron) resistant weeds, their prevention is at problem.

Can especially grow a large amount of important monocotyledon weeds for influencing economic benefits in rice crops, for example, mainly barnyard grass, Ischaemum or moleplant seed can not possibly obtain satisfied control using a kind of rice crops herbicide being currently known or combinations thereof and imitate Fruit.In addition it has also been found that noxious plant from global rice growing system：Such as Sagittaria, needle Lin category, such as scouring rush's shape water chestnut, water Sha Grass, firefly Lin and other noxious plants, they are mainly the rudiment from perennial tissue in soil, therefore more miscellaneous than seed germination Grass is more difficult to control, and is not easily controlled best broad leaved weed type in entire weeds spectrum.Moreover, resistant weed type occurs Rate increases (including Herba Cyperi Glomerati category or needle Lin belong to), this makes using single-activity component or even if common combinations can not control this A little weeds.

Sulfonylurea herbicide is selective inner-adsorption conduction-type herbicide, is easily absorbed by the root of plant, leaf, in xylem and Bast conducts, it can inhibit the activity of vital acetolactate synthestase (ALS) in plant.Sulfonylurea herbicide There are still some problems in application process, wherein most outstanding is that it remains key and weeds resist sulfonylurea herbicide Pharmacological property problem.

The method of conventional control weeds be into existing preparation addition can effectively prevent have to sulfonylurea herbicide it is anti- The active constituent of the weeds of property, to increase the active constituent number in the combination agent for weeds.In this case, it needs There is such herbicide, they have satisfactory effect for the weeds of anti-sulfonylurea herbicide, and can reduce composition The amount of middle active constituent.

Promazine Sulfometuron Methyl (Propyrisulfuron) is the pyrimidine radicals sulfonylurea herbicide developed by SUMITOMO CHEMICAL chemistry Agent is mainly used for rice terrace and prevents and kill off the grass family such as barnyard grass and broad leaved weed.The product dosage is low, is removed to certain known sulfonylureas The weeds that careless agent generates resistance have good preventive effect.

The molecular formula of promazine Sulfometuron Methyl is C16H18O5N7SCl, and molecular structure is as follows：

Cyhalofop-butyl (cyhalofop-butyl) is fragrant phenoxy phenoxy propionic acid herbicide, has tight security to rice, With uptake and translocation.Medicament is absorbed via blade, the leaf sheath of weeds, is conducted through bast, is accumulated in weeds meristem zone, Acetyl-CoA carboxylase (ACCase) is resisted, aliphatic acid synthesis is made to stop, the growth division of cell cannot be normally carried out, membrane system The structures containing fat such as system are destroyed, and Plant death is finally resulted in.It is slower it to be absorbed into weeds death from cyhalofop-butyl, generally requires 1-3 weeks.The symptom of weeds after administration is as follows：The tender shoots atrophy of four leaf stage, leads to death.The old leaf of two leaf stage changes very little, Keep green.Cyhalofop-butyl is higher to grass family moleplant seed, barnyard grass preventive effect, while and anti-lady's-grass, Paspalum distichum, green bristlegrass, ox Muscle grass, etc..Cyhalofop-butyl is invalid to sedge weed and broad leaved weed, especially to the above broad leaved weed of 4 leaves；When high dose pair 2 leaf age angustifolia arrowhead herbs also only have certain inhibiting effect, and herbicide controlling spectrum is relatively narrow.Cyhalofop-butyl is for many years pushed away in the form of single dose always Wide application, the rising year by year of Weed Resistance caused by after use, dosage increase year by year, and use cost is higher and higher.

Cyhalofop-butyl after rice absorbing, is degraded rapidly to two acid-state inactive to acetyl-CoA carboxylase, thus right Rice is highly safe.Cyhalofop-butyl is degraded rapidly in soil, typical rice field water, to succession crop safety.

Still individually active ingredient using promazine Sulfometuron Methyl as herbicide prepares weeding to common practice in industry at present Drug does not occur so far by the technology of promazine Sulfometuron Methyl and other active ingredient mixtures.Studies have shown that individually with promazine Sulfometuron Methyl As the active ingredient of herbicide, there is also certain deficiencies, for example, it is not high enough to crop safety, herbicide controlling spectrum is not wide enough, medicine Object residual effect difference etc. is difficult to reach best so as to cause control of weeds effect.
