Abstract
The invention belongs to a herbicide for removing monogenus or dicotyledonous weeds in a paddy field, in particular to a compound herbicide with effective active components in percentage by weight: 1pyrazosulfuron-ethyl, 0.75-2 grass amine sulfonamide pentafluoride and 4-7 cyhalofop butyl as well as preparations with different contents and a plurality of preparation formulations; and the compoundherbicide comprises the effective active components, a wetting additive, a filler, and the like. The invention obviously improves the effect, increases a weed control speed, obtains the effect of preventing and removing a plurality of broad-leaved weeds and gramineae weeds in a paddy field after compounding the pyrazosulfuron-ethyl, the grass amine sulfonamide pentafluoride and the cyhalofop butyl, has low toxicity and remains, expands a weed removal spectrum, remarkably reduces the dosage, the medicament-applying number and the medicament cost and is beneficial to delaying the succession speed of weed communities and prolonging the service life of the herbicide.
Description
Technical field:
The invention belongs to the chemical herbicide of preventing and kill off grassy weeds such as the multiple broad leaved weed of paddy field and barnyard grass grass, moleplant seed, relate to the complex weedicide that a kind of effective active components is pyrazosulfuron, penoxsuam and cyhalofop-butyl.
Background technology:
The use of chemical herbicide is that vast farmers is in order to reduce labor intensity, can effectively control the farmland crop smothering again, capture one of major measure of higher yield of crops, from now on for a long time in also inevitably by using chemical herbicide to prevent and kill off weeds in field, reduce labor intensity, improve crop yield.
In order to protect food security; the protection environment; the protection human beings'health; the research and development of chemical herbicide just develop towards efficient, low toxicity, low-residual direction with application; researchers at different levels have been done fruitful effort for it, and new, as to be subjected to that vast farmers welcomes efficient, low toxicity, the chemical herbicide kind of low-residual constantly occur.
New, as to be subjected to the complex weedicide that society welcomes continuous appearance is used alternatingly weed killer herbicide with updating the use habit of weed killer herbicide, comprising.For delaying the speed of weeds population succession, prolong a kind of service life of weed killer herbicide, finally reduce the usage amount of weed killer herbicide, new approach is provided.
Pyrazosulfuron (pyrazosulfuron ethyl) is a sulfonylurea herbicide, low toxicity, and the mouse acute oral lethal dose of 50＞5000 mg/kg is to fish safety.It is selectivity inner sucting conduction type herbicide for paddy field.Can spread rapidly in water after using, after being absorbed by the weeds root, conduct in the plant body, suppress acetolactate synthestase, hindered aminoacid is synthetic, and inhibition weeds cauline leaf is grown and root stretches, and causes weeds withered.Be used for transplanted rice field, seedling throwing field and live field, can prevent and kill off annual and perennial broadleaf weed and sedge weeds such as needle spikesedge herb, Procumbent Falsepimpernel, mexicana, Herba Ammanniae Bacciferae, short arrowhead, wild arrowhead, carp intestines, Monochoria vaginalis, rhizoma alismatis, difformed galingale herb, pondweed, false loosestrife.To rice safety, has selectivity.
Penoxsuam (penoxsulam) is a kind of triazolopyrimidine sulfonamides herbicide, low toxicity.Absorb by grass cutting blade, sheath portion or root, conduct to meristematic tissue, impel that weeds stop growing, yellow, death.Be used for rice direct seeding field and transplant field, can prevent and kill off grassy weed, sedge weed and broad leaved weeds such as barnyard grass grass, difformed galingale herb, carp intestines, Monochoria vaginalis, Monochoria korsakowii, bur beggar-ticks, miliary fimbristylis herb, wild arrowhead, mexicana, Procumbent Falsepimpernel, preventive effect to the barnyard grass grass is particularly outstanding, above the average age for marriage barnyard grass grass there is splendid preventive effect, effective to the barnyard grass grass of multiple subspecies simultaneously, comprise the barnyard grass grass that dichloro quinolinic acid, Stam F-34 is produced resistance, the weeds that many sulfonylureas produced resistance also have good preventive effect, but invalid to moleplant seed.Under the recommended dose to rice safety.
Cyhalofop-butyl (cyhalofop butyl) is that a kind of fragrant phenoxy propionic acid class selectivity inner sucting conduction type cauline leaf is handled weed killer herbicide.Low toxicity.Handle as cauline leaf, the stem, the leaf that can be plant absorb, and are transmitted to growing point and meristematic tissue, and the fatty acid that suppresses weeds by the inhibition to acetyl-CoA carboxylase is synthetic, suppresses weed growth, stopped growing in several days by the medicine weeds, and be withered gradually later on.This medicine can be degraded to the diacid attitude of non-activity rapidly in the paddy rice body, and to the paddy rice high safety.The rice field that can be used for various planting patternss, it is wide to have a dispenser phase, to succession crop safety, can effectively prevent and kill off grassy weeds such as barnyard grass grass, moleplant seed, amur foxtail, Paspalum distichum, lady's-grass.
Use above-mentioned a kind of weed killer herbicide separately, not only cost is higher, and the grass spectrum is narrow extremely, can not reach and once prevent and kill off multiple broad leaved weed and grassy weeds such as barnyard grass grass, moleplant seed.
The reasonable composite of weed killer herbicide is to improve preventive effect, expansion grass spectrum extremely, delays the speed of weed community succession, alleviates the pollution to environment, reduces a kind of effective ways of herbicide residue.Through screening, pyrazosulfuron and penoxsuam, cyhalofop-butyl is composite, can realize above-mentioned a series of advantage.
Summary of the invention:
The objective of the invention is to: not wide at using at present separately pyrazosulfuron or penoxsuam or cyhalofop-butyl to prevent and kill off to kill in the paddy field weed process grass spectrum, be difficult to reach the practical problem of effectively preventing and kill off purpose, provide a kind of pyrazosulfuron penoxsuam cyhalofop-butyl composite weed killer herbicide.
The object of the present invention is achieved like this: a kind of pyrazosulfuron penoxsuam cyhalofop-butyl complex weedicide comprises effective active components, wettability auxiliary agent and filler, it is characterized in that: effective active components is pyrazosulfuron and penoxsuam and cyhalofop-butyl.The mass ratio of pyrazosulfuron and penoxsuam, cyhalofop-butyl is 1: 0.75～2: 4～7.
The complex weedicide preparation effective component content that the present invention relates to is 10-60%.
The complex weedicide formulation that the present invention relates to is wetting powder, suspending agent, water dispersible granules, soluble powder, missible oil etc.
The invention has the advantages that: after pyrazosulfuron and penoxsuam, cyhalofop-butyl are composite, having obtained has the notable synergistic effect to grassy weeds such as the multiple broad leaved weed of paddy field and barnyard grass grass, moleplant seeds, the dead speed of weeds is fast, enlarge with killing the grass spectrum than single, simultaneously can reduce dosage, and delay the speed of weeds population succession.
